What is the slope of the situation?

==============================================================

Explanation:

Let x and y be the two integers where x > y.

The two integers have a sum of x+y and this is equal to 2, so x+y = 2. Solve for y to get y = -x+2

The two integers also have a difference of 12, so x-y = 12. Plug in y = -x+2 and solve for x

x-y = 12

x - ( y ) = 12

x - ( -x+2 )  = 12 ... replace y with -x+2

x + x - 2 = 12

2x - 2 = 12

2x - 2+2 = 12+2 .... adding 2 to both sides

2x = 14

2x/2 = 14/2 .... divide both sides by 2

x = 7

Use this x value to find y

y = -x+2

y = -7+2

y = -5

--------------------------------------

As a check,

x+y = 7+(-5) = 7-5 = 2 ... we get a sum of 2

x-y = 7-(-5) = 7+5 = 12 ... and get a difference of 12

Answer:

(-1, 4)

Step-by-step explanation:

In the figure attached,

Ordered pair representing point P is (3, 4) [parallel to y-axis]

If this point has been reflected across a line x = 1

New point after reflection across x = 1 will be,

P(3, 4) → P'(-1, 4)

Since point P and P' will be equidistant from the line (x = 1), so the x ordinate of P' will be = 3 - 4 = -1

And y-ordinates of point P' will be same as y = 4

Answer: t = 7.85seconds

Step-by-step explanation:

Given that :

Height of tower = 986 Feets

Function s(t) = 16t^2

To find the time t 8 in Seconds taken for an object to fall to the ground from the top of the​ building

16t^2 = 986

t^2 = 986/16

t ^2 = 61.625

Take the square root of both sides

t = sqrt(61.625)

t = 7.85seconds

Answer:

7.85sec

Step-by-step explanation:

Given that,

s(t)=16t squared​, where t is time in seconds. The height of a certain tower is 986 feet.

s(t) = 16t²

so when s = 986feet

16t² = 986 feet

t² = 986 /  16

t² = 61.625

t = √61.625

t= 7.85 seconds

Answer:

60 degrees.

Step-by-step explanation:

We know that we can rotate the image by a total of 360 degrees until we reach the original point again.

To rotate the image to a point where the image looks the same, we need to take a look at how we can do this. We want to line up the image with the gap between the two white semicircles. There are a total of 6 of these gaps:

360/6 = 60 degree rotations will make the image the same.

Answer:

The angle of elevation for Brendan is  40°

Step-by-step explanation:

To find the angle of elevation of Brendan, we will follow the steps below;

we can use the sine formula to find the angle of elevation of Brendan since we were given two sides and one angle

Using the sine rule;

[tex]\frac{sin A}{a}[/tex] = [tex]\frac{sin E}{e}[/tex]

From the diagram above, angle A = 65°     side a = 155 m   side e=110 m

angle E is what we are to find

we can now proceed to insert the values into the formula

[tex]\frac{sin 65}{155}[/tex]  =  [tex]\frac{sin E}{110}[/tex]

cross-multiply

155 sinE = 110 sin65°

Divide both-side of the equation by 155

sin E = 110 sin65° / 155

sin E =0.64319

Take the sin⁻¹  of both-side of the equation

sin⁻¹ sin E = sin⁻¹ (0.64319)

At the left-hand side of the equation sin⁻¹ will cancel-out sin leaving us with just E

E =  sin⁻¹ (0.64319)

E= 40°

The angle of elevation for Brendan is  40°

Answer:

10.50+10.50+7.95=$28.95

Answer:

Step-by-step explanation:

1)Since he can lose 5 pounds per week, this is a linear rate. The weight is decreasing in arithmetic progression. The formula for determining the nth term of an arithmetic progression is expressed as

Tn = a + (n - 1)d

n = number of terms(weeks)

d = common difference(5 pounds)

a= first term(300 pounds)

The equation that could be used to find how many weeks, w, it would take for him to weigh 150 pounds would be

150 = 300 + (w - 1)5

150 - 300 = 5w - 5

- 150 + 5 = 5w

w = 145/5 = 29 weeks

2) t represents the number of hours used to fix the car. The cost of t hours is 52t. Total amount paid is 210 + 52t. The equation that could be used to find, t, the length of time it took to fix the car is

210 + 52t = 527.23

3) 52t = 527.23 - 210 = 317.23

t = 317.23/52

t = 6 hours

3) Let x represent the time it will take before you and your sister have the same amount of money. The amount that you would have in x weeks is 60 + 7x

The amount that you sister will have in x weeks is 120 + 5x. The equation would be

60 + 7x = 120 + 5x

7x - 5x = 120 - 60

2x = 60

x = 60/2 = 30 weeks

4) let L represent the length of the parking lot.

let W represent the width of the parking lot.

If the length of a rectangular parking lot is 3 times its width, it means that

L = 3W

Its perimeter is 840 yards. It means that

2(L + W) = 840

L + W = 840/2 = 420

Substituting, it becomes

3W + W = 420

4W = 420

W = 420/4 = 105

L = 3 × 105 = 315

Length = 315 yards

Answer:

29.49 square inches

Step-by-step explanation:

Let the length of the rectangle be x inches

Therefore, width = (2x - 7) inches

Perimeter of rectangle =2( length + width)

therefore,

43.6 = 2 ( x + 2x - 7)

43.6/2 = 2 ( 3x - 7)

21.8 = 6x - 14

21.8 + 14 = 6x

6x = 35.8

x = 35.8/6

x = 5.97 inches

Length = 5.97 inches

width = 2*5.97-7 =11.94 - 7 = 4. 94 inches

Area of rectangle

= Length * width

= 5.97*4.94

=29.4918

= 29.49 square inches

Answer:80mi/hr * 3.5hrs

Answer:

502.40 inches

Step-by-step explanation:

First we need to find the circumference of the wheel, which is given by pi times the diameter:

C = (3.14)(20) = 62.8 inches

That's how far the unicycle will travel in 1 revolution, so from there just multiply by 8

D = (62.8)(8) = 502.40 inches

The unicycle travel 502 inches in 8 revolutions

The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

Given that, a unicycle wheel has a diameter of 20 inches.

To find that how many inches will the unicycle travel in 8 revolutions, we will multiply the circumference to the asked number of revolutions.

Circumference = π × diameter

= 3.14 × 20 = 62.8 inches

The unicycle travel in 8 revolutions = 62.8 × 8 = 502.4 inches

In nearest hundred = 502 inches

Hence, the unicycle travel 502 inches in 8 revolutions

Answer:

0.6206

Step-by-step explanation:

We would be using the Z score probability to answer this question

The formula to find the is given as :

is z = (x-μ)/σ,

x = observed value

μ = mean or average value

σ = Standard deviation

To find the probability that between 3,000 and 4,800 acres will be burned in any given year

Step 1

Find the probability that that between 3,000 will be burned in any given year

z = (x-μ)/σ,

x = observed value = 3000

μ = mean or average value = 4500

σ = Standard deviation = 780

z = (3000- 4500)/780

z = -1.92308

Step 2

Find the probability that that between 4,800 will be burned in any given year

z = (x-μ)/σ,

x = observed value = 4800

μ = mean or average value = 4500

σ = Standard deviation = 780

z = (4800- 4500)/780

z =0.38462

Step 3

Using the Z score normal distribution table:

= P(Z <0.38462) - P(Z < - 1.92308)

= P(-1.92308 < Z < 0.38462)

Using the Z score normal distribution table:

P(z) -1.92308 = 0.02743

P(z) 0.38462 = 0.64803

Therefore, the probability that between 3,000 and 4,800 acres will be burned in any given year

0.64803 - 0.02743

= 0.6206

Answer: 0.6225

Step-by-step explanation:

$P\left(3,000<X<4,800\right)=0.6225

The mean is μ=4500 and the standard deviation is σ=780. Because the probability between two values is to be calculated, subtract the probability of the lower value from the higher value. In this case, you have to use the NORMDIST function twice.

1. Open Excel and click on any empty cell. Click Insert function, fx.

2. Search for NORMDIST in the search for a function dialog box and click GO.

3. Make sure NORMDIST is on top in select a function. Then click OK.

4. In the function arguments of the NORMDIST function, enter 4800 for X, 4500 for mean, 780 for Standard_dev, and TRUE for Cumulative, all for the higher value of X. Thus, the answer, rounded to four decimal places, is 0.6497.

5. Click on any other empty cell. Click Insert function, fx.

6. Search for NORMDIST in the search for a function dialog box and click GO.

7. Make sure NORMDIST is on top in select a function. Then click OK.

8. In the function arguments of the NORMDIST function, enter 3000 for X, 4500 for mean, 780 for Standard_dev, and TRUE for Cumulative, all for the lower value of X. Thus, the answer, rounded to four decimal places, is 0.0272.

Now subtract: 0.6497−0.0272=0.6225. Thus, the probability that between 3,000 and 4,800 acres will be burned in any given year is 0.6225.

Answer:

Perimeter of Isosceles Triangle = 16 units

Step-by-step explanation:

Area of rectangle is given by the formula;

Area = 1/2 × base × height

From the diagram, base = 6x - 6 and height = 6x - 8

Thus,Area = 1/2 × (6x - 6) × (6x - 8)

Area = (3x - 3)(6x - 8) = 18x² - 42x + 24

Secondly, area of rectangle is given by;

Area = length x breadth

So, area of rectangle in question = (6x - 9)(3x - 2) = 18x² - 39x + 18

We are told both the area of the triangle and the rectangle are the same, so let's equate both areas;

18x² - 42x + 24 = 18x² - 39x + 18

18x² will cancel out and rearranging, we have;

24 - 18 = 42x - 39x

6 = 3x

x = 6/3

x = 2

Plugging 2 for x for the height and base of the triangle, we have;

base = 6(2) - 6 and height = 6(2) - 8

Base = 6 and height = 4

So,let's find the slant height of the isosceles triangle.

Dividing the base by 2,we have; 6/2 = 3

So,using Pythagoras theorem, let the slant height be h, so we have;

h² = 3² + 4²

h² = 9 + 16

h² = 25

h = √25

h = 5

2 slant sides of isosceles triangle are the same. So perimeter = 5 + 5 + 6 = 16 units

Formula for volume of a cone:

[tex]V' = \dfrac{1}{3}\pi R^{2} H ...... (2)[/tex]

Where [tex]R[/tex] is the radius of base of cone

and [tex]H[/tex] is the height of cone

Now, it is given that height and radius of cone are equal.

[tex]r = R\\h =H[/tex]

Putting the values in equation (2):

[tex]V' = \dfrac{1}{3}\pi r^{2} h[/tex]

Using equation (1):

[tex]V' = \dfrac{1}{3} \times V[/tex]

Putting V = 180 cubic meters

[tex]\Rightarrow V' = \dfrac{1}{3} \times 180\\\Rightarrow V'=60 \text { cubic meters}[/tex]

9.16 meters

The length of sandbox 2 is 9.16 meters.

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure. The square unit, which is frequently expressed as square inches, square feet, etc., is the accepted unit of area.

Given Two sandboxes with the same area,

area of sand box 1 = 25 m²

area of sand box 2 = w(3w+1) = 25

25 = w(3w + 1)

3w² + w - 25 = 0

w = 2.7248 (round to 2.72 m)

length is (3w + 1) = 3(2.72) + 1 = 9.16 m

Answer:

a) 1 and 7 = congruent

b) 2 and 5 = supplementary

c) 4 and 6 = congruent

d) 3 and 8 = supplementary

Step-by-step explanation:

Congruent angles are the same, but in different forms. So they might be flipped around, but they are still the same angle and they have the same number of degrees.

Supplementary angles are 2 angles that add up to 180 degrees.

For example, you know that 2 + 3 = 180 degrees, because its sitting on a straight line, and so they are supplementary. They have been cut unevenly which makes 2>3. Same goes for all the other pairs of angles. Using this, you can determine which ones are supplementary and congruent.

So, even though they haven't given you exact values for each of the angles, just by looking at the shape, you can often tell very easily what kind they are:

*acute angles = angles that are less than 90 degrees

*obtuse angles = angles more than 90 degrees, but less than 180 degrees.

a) 1 and 7 have the same shape. Both are acute angles, just flipped upside down.

b) 2 and 5 are complementary. 5 is an acute angle, like 1 and 7. 2 is an obtuse angle, like 6 and 8. If you look at it closely, you can tell that they add up to 180 degrees.

c) 4 and 6 are congruent. They are both obtuse angles.

d) 3 and 8 are supplementary. 3 is an acute angle and 8 is obtuse.
