Answer:

Step-by-step explanation:

To find the highest price Jenny can charge to earn $125 in profit, first write an equation.

total profit = profit per card * number of cards

You want to know when Jenny will earn $125 in profit, and the price per card, x, is the variable. The expression 0.7x represents the profit per card.

125=0.7x(–15x+120)

Now, solve for x. Start by writing the equation in standard form

125=0.7x(–15x+120)

125= –10.5x2+84x

0= –10.5x2+84x–125

Now to solve for x, you can use the quadratic formula with a= – 10.5, b=84, and

So, to the nearest dollar, the highest price Jenny can charge per card to earn $125 in profit is $6.0236 or $6.

Answer:10.66 years. Punch again to double check

Step-by-step explanation:

A=Pe^(rt)

11700=5850e^(.065t)

isolate the variable expression

2=e^(.065t) divide by 5850

ln2=lne^(.065t) take the natural log of both sides

ln2=.065t. Bring down the power, lne equals

t is about 10.66 years. Divide ln2 by .065

The lateral and total surface area of the prism are 1000 square feet and 1120 square feet.

In this problem we need to determine the lateral and total surface area of a prism with a triangular base. The lateral surface area is the sum of the areas of the three rectangles and the total surface area is the sum of the lateral surface area and the areas of the two triangles.

The area formulas for the triangle and the rectangle are, respectively:

Triangle:

A = s · √[s · (s - a) · (s - b) · (s - c)]

s = 0.5 · (a + b + c)

Where:

Rectangle:

A = w · h

Where:

Now we proceed to determine each surface area:

Lateral surface area:

A = 2 · (20 ft) · (17 ft) + (20 ft) · (16 ft)

A = 1000 ft²

Total surface area:

s = 0.5 · (17 ft + 17 ft + 16 ft)

s = 25 ft

A = √[(25 ft) · (25 ft - 17 ft)² · (25 ft - 16 ft)] + 1000 ft²

A = 1120 ft²

To find the slope in this problem, we can use the formula for calculating slope, which is change in distance divided by change in time. In this case, the change in distance is 350 miles - 200 miles = 150 miles, and the change in time is 4:00 pm - 1:00 pm = 3 hours.

So, the slope (rate of driving) is 150 miles / 3 hours = 50 miles per hour.

Therefore, Sue will drive an additional 50 miles by 5:00 pm, making her total distance driven by 5:00 pm 200 miles + 150 miles + 50 miles = 400 miles. So, Sue will drive 400 miles by 5:00 pm if she continues at the same rate. Note that in this problem, we are assuming that Sue maintains a constant speed throughout her drive. If her speed changes, the solution may be different.

Answer:

C. (–3, –7)

Step-by-step explanation:

We can check each ordered pair by substituting the values of x and y into the equation y = x - 4 and see if the equation is true.

A. (-3, 7)

y = x - 4

7 = -3 - 4

7 = -7

This is not true, so (-3, 7) is not a solution.

B. (3, -7)

y = x - 4

-7 = 3 - 4

-7 = -1

This is not true, so (3, -7) is not a solution.

C. (-3, -7)

y = x - 4

-7 = -3 - 4

-7 = -7

This is true, so (-3, -7) is a solution.

D. (3, 7)

y = x - 4

7 = 3 - 4

7 = -1

This is not true, so (3, 7) is not a solution.

Therefore, the only ordered pair that is a solution of y = x - 4 is (–3, –7).

Since Q is the midpoint of NP, we know that NQ = QP. Similarly, we know that RS is the midpoint of OP, so we have RS = SO.

Let's label the length of QS as x. Then, we know that QR = 2x and SR = 3x.

To find the perimeter of triangle NOP, we need to find the lengths of NO, OP, and NP.

Using the Pythagorean Theorem, we can find that:

NO^2 = NQ^2 + OQ^2

NO^2 = (QP)^2 + (SO)^2

NO^2 = (x)^2 + (2x)^2

NO^2 = 5x^2

NO = x√5

Similarly, we can find that:

OP^2 = OQ^2 + PQ^2

OP^2 = (SO)^2 + (QP)^2

OP^2 = (3x)^2 + (x)^2

OP^2 = 10x^2

OP = x√10

Finally, we know that NP = NO + OP, so:

NP = x√5 + x√10

NP = x(√5 + √10)

To find the perimeter of NOP, we add up the three sides:

Perimeter of NOP = NO + OP + NP

Perimeter of NOP = x√5 + x√10 + x(√5 + √10)

Perimeter of NOP = x(2√5 + 2√10)

Perimeter of NOP = 2x(√5 + √10)

We can substitute the value we found for QS, which is x, to get:

Perimeter of NOP = 2(5 + 2√10)

Perimeter of NOP = 10 + 4√10

Therefore, the perimeter of triangle NOP is 10 + 4√10 units.

The equation expressing d as a function of t can be found by using the formula for distance traveled with constant speed:

d = vt

where d is the distance, v is the constant speed, and t is the time elapsed.

In this case, the speed is 150 cm/s, so the equation is:

d = 150t

To find the total distance traveled in meters at t = 2 seconds, we need to first find the total distance traveled in centimeters at t = 2 seconds:

d = 150t

d = 150(2)

d = 300 cm

To convert to meters, we divide by 100:

d = 300/100

d = 3 meters

Therefore, at t = 2 seconds, the object has traveled a total distance of 3 meters.

The value of the variable x is -4

First, we need to know that line segments are described as a section of a line that is bounded by two points or connecting two points.

Now, equate the expressions since they are of equal lengths, we have;

3x + 19 = 5x - 11

collect the like terms

3x - 5x = -11 + 19

The exact values for both equations are as follows:

a) 3

b) -√3/2 - √2/2

a) In order to ascertain the precise value of 4sin(π/6) + tan(π/4), we must first evaluate the trigonometric functions involved: sin(π/6) = 1/2 and tan(π/4) = 1.

Now, by substituting these values in the equation, we get

4(1/2) + 1 = 2 + 1 = 3.

b) To calculate cos(4π/3) tan(330°) - sin(3π/4), it is necessary to convert 330° into radians: (330 * π) / 180 = 11π/6.

After setting this conversion, evaluate the trigonometric functions present: cos(4π/3) = -1/2, tan(11π/6) = √3, and sin(3π/4) = √2/2.

When these values are used within the equation, the result is (-1/2)(√3) - (√2/2) which equals -√3/2 - √2/2.

Ergo, the exact values for both equations are as follows:

a) 3

The measure of <RTV = 1/2 * (99 - 45) = 27 degrees

Geometrically speaking, a secant is an intersecting line that marks two separate points on the circumference of a circle.

Primarily, it serves as a chord drawn across the diameter which transverses through each endpoint connecting them. The magnitude of the secant is determined by the distance between these intersectional points. This particular element of geometry has various applications in trigonometry, particularly in computing angles and lengths within circles.

According to the Exterior Angle of a Circle Theorem, the measure of an exterior angle of a circle formed by two secants is equal to half the difference of the measures of the intercepted arcs:

Using this theorem,

In the given diagram, the volume of the composite shape is 12,672 ft³

From the question, we are to calculate the volume of the given composite shape

The composite shape is made up of a pyramid and a cuboid

Thus,

Volume of the shape = Volume of pyramid + Volume of cuboid

Volume of pyramid = 1/3 × base area × height

Answer: First, let's convert the room's dimensions from feet to yards, since the carpet cost is given per square yard:

17 feet = 5.67 yards (rounded to two decimal places)

16 feet = 5.33 yards (rounded to two decimal places)

Next, we can calculate the area of the room in square yards by multiplying these values:

Area = 5.67 yards × 5.33 yards = 30.23 square yards (rounded to two decimal places)

Finally, we can multiply the area by the cost per square yard to get the total cost:

Total cost = 30.23 square yards × $101/square yard = $3,056.23 (rounded to two decimal places)

Therefore, it will cost $3,056.23 to carpet the room.
