The cost of one movie ticket, including sales tax, is $13.02
The cost of the movie ticket is $12.00, and the sales tax rate is 8.5%. To find the amount of sales tax on the ticket, we can multiply the ticket price by the tax rate:
Sales tax = 12.00 * 0.085
= 1.02
So the sales tax on the ticket is $1.02.
To find the total cost of the ticket, we add the ticket price to the sales tax:
Total cost = 12.00 + 1.02
= 13.02
Therefore, the cost of one movie ticket, including sales tax, is $13.02.

P(x;y)= -mx3m-1 y2m-7
Un monomio que cumple : GA=17. Calcula
E= GR(x). GR(y)
According to given data GR(x) * GR(y) = 3 * 2m - 5
The given monomial is P(x;y) = -mx^3m-1 * y^2m-7, and it is known that GA(P) = 17.
We need to find the values of GR(x) and GR(y), which are the degrees of the monomial with respect to x and y, respectively.
Using the formula GA(P) = GR(x) + GR(y), we get GR(x) + GR(y) = 17.
Now, we can write the monomial as P(x;y) = (-m) * x^(3m-1) * y^(2m-7).
Therefore, GR(x) = 3m-1 and GR(y) = 2m-7.
Multiplying these two values, we get GR(x) * GR(y) = (3m-1) * (2m-7) = 6m^2 - 23m + 7.
Hence, the final answer is GR(x) * GR(y) = 6m^2 - 23m + 7.

Melanie does not have enough grass seed to make a lawn.
To find out if Melanie has enough grass seed to make a lawn by 12m by 14m, we need to calculate the area of the lawn and compare it to the amount of grass seed she has.
The area of the square lawn is 8m x 8m = 64 square meters. To cover this area with 5kg of grass seed, we can calculate the amount of grass seed needed per square meter: 5kg / 64 square meters = 0.078125 kg/square meter.
The area of the rectangular lawn is 12m x 14m = 168 square meters. To cover this area with the same amount of grass seed per square meter, we can calculate the total amount of grass seed needed: 168 square meters x 0.078125 kg/square meter = 13.125 kg.
Since Melanie only has 4 boxes of grass seed, which is a total of 12kg, she does not have enough to cover the rectangular lawn. She would need at least 1.125 kg more grass seed to cover the area.

7. the interest on a particular savings account is compounded continuously. the account initially had $3500 deposited in it. the worth of the account after t-years can be calculated using the formula: a(t)- 3500041 (a) by what percent will the worth of the account increase per year? round to the nearest hundredth of a percent. (b) to the nearest tenth of a year, how long will it take for the worth of the account to triple?
With the given formula [tex]a(t) = 3500e^{(0.041t)[/tex], the percent increase per year for savings account is 4.1% and it will take about 16.9 years for the worth of the account to triple.
a) The formula given is: [tex]a(t) = 3500e^{({0.041t)[/tex]
To find the percent increase per year, we need to find the annual growth rate. We can do this by taking the derivative of a(t) with respect to t:
[tex]a'(t) = 0.041 * 3500 * e^{(0.041t)[/tex]
The annual growth rate is equal to a'(t)/a(t). Plugging in the formula for a(t) and simplifying, we get:
a'(t)/a(t) = 0.041
So the percent increase per year is 4.1%.
b) We want to find the time it takes for the account to triple in value, so we need to solve for t in the equation:
[tex]3a(0) = 3500e^{(0.041t)[/tex]
Dividing both sides by 3500 and taking the natural logarithm of both sides, we get:
ln(3) = 0.041t
t = ln(3)/0.041
Using a calculator, we get:
t ≈ 16.92 years
So it will take about 16.9 years for the worth of the account to triple.

After some not so high practice dives by the circus owner, the circus performers decide to do a practice run of the show with the diver himself. but they decide to set it up so they will not have to worry about a moving cart. instead, the cart containing the tub of water is placed directly under the ferris wheel’s 11o’clock position. as usual, the platform passes the 3o’clock position at t=0
how many seconds will it take for the platform to reach the 11 o’clock position?
what is the diver’s height off the ground when he is at the 11 o’clock position?
radius = 50 ft
center of wheel is 65 feet off ground
turns counterclockwise at a constant speed, with a period of 40 seconds.
platform is at 3 o’clock position when it starts moving
The ferris wheel will take a total time of 10 seconds for the platform to reach the 11 o'clock position and the diver's height off the ground when he is at the 11 o'clock position is 50 feet.
To determine the time it takes for the platform to reach the 11 o'clock position and the diver's height off the ground, we will use the given information about the ferris wheel.
1. The ferris wheel has a radius of 50 ft and turns counterclockwise at a constant speed with a period of 40 seconds.
2. The center of the wheel is 65 ft off the ground.
3. The platform is at the 3 o'clock position when it starts moving (t=0).
The ferris wheel has a period of 40 seconds, which means it takes 40 seconds for it to make a full rotation. The distance between the 3 o'clock position and the 11 o'clock position is 90 degrees out of 360, which is one-fourth of the total distance around the circle.
Therefore, it will take 1/4 of the total time for the platform to reach the 11 o'clock position, which is 40/4 = 10 seconds.
To find the diver's height off the ground at the 11 o'clock position, we can use the sine function. Let's call the angle formed by the radius from the center of the ferris wheel to the diver and the radius from the center of the ferris wheel to the 3 o'clock position θ.
Since the platform starts at the 3 o'clock position and rotates counterclockwise, θ will increase as time passes. At the 11 o'clock position, θ will be 90 degrees.
We know that the radius of the ferris wheel is 50 feet and the center of the ferris wheel is 65 feet off the ground. Let's call the height of the diver off the ground h. Then we have:
sin θ = h / (50 ft)
h = (50 ft) * sin θ
At the 11 o'clock position, θ = 90 degrees, so we have:
h = (50 ft) * sin 90°
h = 50 ft
Therefore, the diver's height off the ground when he is at the 11 o'clock position is 50 feet.

The expression to find the number of events is: (1 event) / (1/8 side) = (n events) / (1/4 sides).
Devonte is studying for a history test and uses 1/8 of a side of one sheet of paper to write notes for each history event. He fills 2 full sides of one sheet of paper. To find out how many events he wrote notes for, you can set up an expression using the given information.
Since Devonte uses 1/8 of a side for each event, and he fills 2 sides, you can calculate the total amount of space he used by multiplying the fractions: (1/8) * 2. This simplifies to 2/8 or 1/4. Now, you can set up a proportion to find the number of events (n) that Devonte wrote notes for:
(1 event) / (1/8 side) = (n events) / (1/4 sides)
Cross-multiply to solve for n:
1 * (1/4) = n * (1/8)
1/4 = n/8
To find n, multiply both sides by 8:
(8) * (1/4) = n
2 = n
So, Devonte wrote notes for 2 history events using the 2 full sides of one sheet of paper. The expression to find the number of events is: (1 event) / (1/8 side) = (n events) / (1/4 sides).

60 juniors and sophomores were asked whether or not they will attend the prom this year. The data from the survey is shown in the table. Find P(will attend the prom|sophomore).
Attend the prom Will not attend the prom Total
Sophomores 10 17 27
Juniors 24 9 33
Total 34 26 60
The probability of a sophomore attending the prom, given that they were selected from the group of sophomores, is:
P(will attend the prom|sophomore) = (number of sophomores attending the prom) / (total number of sophomores)
From the table, we see that the number of sophomores attending the prom is 10, and the total number of sophomores is 54 (10 + 17 + 27). Therefore:
P(will attend the prom|sophomore) = 10 / 54
Simplifying the fraction, we get:
P(will attend the prom|sophomore) = 5 / 27
So the probability of a sophomore attending the prom is 5/27 (18.519%).

Answer: 12mm
Step-by-step explanation:
Basically, you will find the circumference of the entire circle and then using that find the length of the arc.
So the circumference of the circle is its radius (11) times pi multiplied by 2.
2(11 x 3.14) = 69.08
Now a circle is always 360 degrees and the angle of the sector is 60 degrees.
So we have our circumference and we only need that small portion, so you take and make it a fraction and multiply by the circumference to find the length of that small portion:
60/360 x 69.08 = 11.51
Rounded = 12

The area and cost of each of the lots is given below
What is the area?The area and cost of each of the lots is calculated below
To calculate the rectangle trapezoid, it will be:
B = 140m
h = 50m
b = 70m
Note that Area of Lot 1 : A =(B+b)h/2
Hence Height will be:
A= (140m+ 70m) 50m/2
A = 5250 m²
Cost: C = 5250m² *800 pesos = $4,200,000
Lot 2 is another rectangle trapezoid:
B = 150m
b = 80m
h = 50m
Area: A= (150m+ 80m)50m/2
A = 5750 m²
Cost: C = 5750m² x 800 pesos = $4,600,000
So, for Lot 3 which is a rectangle:
b = 70m
to = 50m
Area: A =a x b
W=50m x 70m
A = 3500 m²
Cost: C = 3500m² x 800 pesos = $2,800,000
Lot 4 is a right triangle:
b = 70m
h = 50m
Area: A =b x h/2
A= (50m x 70m)/2
A = 1750 m²
Cost: C = 1750 m² x 800 pesos = $1,400,000
So for Lot 5 that is a rhomboid:
b = 150 base meters
h=50m
Area: A=b x h
A= (150m x 50m
H = 7500 m²
Cost: C = 7500m² x 800 pesos = $6,000,000
So, for Lot 6 that is an isosceles triangle:
b = 140m
h= 50m
Area: A =b x h/2
A= (140m x 50m)/2
A = 3500 m²

Use the Chain Rule to find Oz/as and Oz/ot. sin(e) cos(6), = st*, Q = st дz as az at 1 x
the Chain Rule to find Oz/as and Oz/ot for the expression sin(e) cos(6), we first need to break it down into its component parts.
Let u = sin(e) and v = cos(6), so that our expression becomes u*v.
Now we can find the partial derivative of Oz/as by using the Chain Rule:
Oz/as = (dOz/du) * (du/as) + (dOz/dv) * (dv/as)
Since Oz = st*, we have dOz/du = st and dOz/dv = t*, so we can substitute those values in:
Oz/as = (st) * (dcos(e)/das) + (t*) * (-sin(6)/das)
To simplify this expression, we need to find the partial derivative of u and v with respect to as:
du/as = (dcos(e)/das)
dv/as = (-sin(6)/das)
Substituting those values back into our original expression for Oz/as, we get:
Oz/as = st * du/as + t* * dv/as
Oz/as = st * (dcos(e)/das) + t* * (-sin(6)/das)
Finally, we can simplify this expression by factoring out the common factor of das:
Oz/as = (st * dcos(e) - t* * sin(6)) / das
To find Oz/ot, we can follow the same steps but with respect to ot instead of as:
Oz/ot = (dOz/du) * (du/ot) + (dOz/dv) * (dv/ot)
Since Oz = st*, we have dOz/du = st and dOz/dv = t*, so we can substitute those values in:
Oz/ot = (st) * (-sin(e)/dot) + (t*) * (-6sin(6)/dot)
To simplify this expression, we need to find the partial derivative of u and v with respect to ot:
du/ot = (-sin(e)/dot)
dv/ot = (-6sin(6)/dot)
Substituting those values back into our original expression for Oz/ot, we get:
Oz/ot = st * du/ot + t* * dv/ot
Oz/ot = st * (-sin(e)/dot) + t* * (-6sin(6)/dot)
Finally, we can simplify this expression by factoring out the common factor of dot:
Oz/ot = (-sin(e)st - 6sin(6)t*) / dot
To find ∂z/∂s and ∂z/∂t using the Chain Rule, let's first define the given functions:
1. z = st (where s and t are variables)
2. s = sin(e) (where e is a variable)
3. t = cos(θ) (where θ is a variable)
Now, apply the Chain Rule to find ∂z/∂s and ∂z/∂t:
Chain Rule states: ∂z/∂x = (∂z/∂s) * (∂s/∂x) + (∂z/∂t) * (∂t/∂x)
1. Find ∂z/∂s:
Since z = st, ∂z/∂s = t
2. Find ∂z/∂t:
Since z = st, ∂z/∂t = s
Now we have ∂z/∂s and ∂z/∂t. You can use these expressions to find the desired derivatives by substituting the given functions for s and t.
∂z/∂s = t = cos(θ)
∂z/∂t = s = sin(e)

Use vector notation to describe the points that lie in the given configuration. (Let t be an element of the Reals.) the line passing through (−1,−1,−1) and (8,−1,6)
As an illustration, at t = 0, we obtain the point (-1, -1, -1), and at t = 1, we obtain the point (8, -1, 6), which are the line's two endpoints.
what is vector ?A vector is a dimensionless parameter in mathematics that has both its magnitude as well as its direction. A vector can be visualised geometrically as an arrow, with the direction and length of the arrow denoting the magnitude and direction of the vector, respectively. A column can be formally described as a component of a feature space. A vector space is a group of things (referred to as vectors) that may be added to and multiplied by scalars, which are often real numbers, in a way that complies with specific axioms. Flow rates, forces, and fields of electricity and magnetism are only a few of the many different types of quantities that can be represented by vectors.
given
Using vector notation, we can write the following for the line that passes through the points (-1, -1, -1) and (8, -1, 6):
r = (-1, -1, -1) + t(9, 0, 7) (9, 0, 7)
The direction of the line is indicated by the vector (9, 0, 7), which is created by deducting the position vectors of the first and second points. We may generate every point along the line by changing the value of the parameter t.
As an illustration, at t = 0, we obtain the point (-1, -1, -1), and at t = 1, we obtain the point (8, -1, 6), which are the line's two endpoints.
We obtain various places on the line for varying values of t.

According to the information, the customer would save $492 in the first year by switching to Intellivision; the customer would save $207 in the second year by using Intellivision; ElectroniSource would be cheaper in the third year.
How to calculate the annual cost for both companies?a. To calculate the annual cost for ElectroniSource: $42/month for phone service x 12 months = $504/year, $35/month for internet service x 12 months = $420/year, and $59/month for cable television x 12 months = $708/year.
So the total annual cost with ElectroniSource would be $504 + $420 + $708 = $1,632.
With Intellivision, the flat monthly fee for all three services is $95, so the total annual cost would be $95 x 12 months = $1,140.
Therefore, the customer would save $1,632 - $1,140 = $492 in the first year by switching to Intellivision.
How to calculate the best rate for the second year?b. After the first year, Intellivision raises the rates by 25%, so the new monthly fee would be $95 x 1.25 = $118.75.
The total annual cost in the second year would be $118.75 x 12 months = $1,425.
Using the same services, the annual cost with ElectroniSource would still be $1,632.
Therefore, the customer would save $1,632 - $1,425 = $207 in the second year by using Intellivision.
How to calculate the best rate for the third year?c. If Intellivision raises the rates by 16% in the third year compared to the second year, the new monthly fee would be $118.75 x 1.16 = $137.95.
The total annual cost in the third year would be $137.95 x 12 months = $1,655.4.
The annual cost with ElectroniSource would still be $1,632.
Therefore, ElectroniSource would be cheaper in the third year.

Your yacht sails in the direction S 71° W for 141 miles. It then turns
and sails in the direction N 63º E 213 miles. Find its distance from
the starting point. Round answer to nearest hundredth.
We can use the Law of Cosines to solve this problem. Let's call the starting point A, the point where the yacht turns B, and the final destination C.
Then we can use the given distances to find the length of each side of the triangle ABC, and the angles to find the angle opposite each side.
Using the angle opposite side AB as a reference angle, we can find the other angles as follows:
Angle BAC = 180° - (71° + 63°) = 46°
Angle ABC = 180° - (46° + 90°) = 44°
Now we can use the Law of Cosines:
[tex]AC^2 = AB^2 + BC^2 - 2ABBCcos(44°)[/tex]
[tex]AC^2 = (141)^2 + (213)^2 - 2(141)(213)*cos(44°)[/tex]
AC ≈ AC^2 = AB^2 + BC^2 - 2ABBCcos(44°)(rounded to the nearest hundredth)
Therefore, the distance from the starting point is approximately 281.21 miles.

In △def, d = 20, e = 25, and f = 30. find m∠f to the nearest degree.
m∠f to the nearest degree is 83°.
The Law of Cosines is used to find an angle when all triangle sides are known.
f² = d² +e² -2de cos(F)
To find angle ∠F, we need to find the value of cos(∠F), which we can do by rearranging the Law of Cosines as follows:
cos(F) = (d² +e² -f²) / (2de)
cos(F) = (20² + 25² - 30²) / (2 × 20 × 25)
cos(F) = (400 + 625 - 900) / (1000)
cos(F) = 125/1000
∠F = arccos(1/8)
∠F = 82.8°
Rounding to the nearest degree
∠F = 83°
Hence, m∠f to the nearest degree is 83°.
