Answer:

12y = -7

Step-by-step explanation:

Answer:

B (the one upper right)

Step-by-step explanation:

1. X is at most, something, so x is = or <

2. X is at most 500 more than twice y ---> (2y + 500)

3. X ≤ 2y +500

4. Profits will be over 22500, so 22500 is less (<) than profit

5. Square of profits are 35 times x and 50 times y

6. P^2 = 35x + 50y

7. P = Square-root of (35x + 50y)

8. 22500 < Square-root of (35x + 50y)

Answer is (3) and (8), which is B

$4 I got it right on a quiz

If the relation is given as p (h)= 14 + 3h. Then the price to rent a bike for 2 hours will be $20.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A company rents bikes.

The price (p) in dollars, to rent a bike for h hours can be found using the formula p (h)= 14 + 3h.

Then the price to rent a bike for 2 hours will be

p (h)= 14 + 3 x 2

p (h)= 14 + 6

p (h)= $20

Answer:

29.32

Step-by-step explanation:

We are given the diameter on the bottom, so we can find the radius. Since a radius is half the diameter, the radius is 2mi. The formula for the volume of a cone is:

1/3 * pi * r^2 * h

We can substitute:

1/3 * pi * 2^2 * 7

29.32153

This rounds to about 29.32

Answer:

V = 117.23

Step-by-step explanation:

V = (1/3) pi x r^2 x h

Input.

V = (1/3) 3.14 x 4^2 x 7

V = (1/3) 3.14 x 16 x 7

V = (1/3) 3.14 x 112

V = (1/3) 351.68

V = 117.23

Note: Please disregard my answer as I used the incorrect radius. I needed to find the correct radius instead of using the diameter as it was.

The resulting shape M'S'V' is smaller than the original shape MSV, so it is therefore classified as a reduction.

Answer: [tex]9\ ft[/tex]

Step-by-step explanation:

Given

Height of the cylinder [tex]h=5\ ft[/tex]

Volume of the cylinder [tex]V=1271.7\ ft^3[/tex]

The volume of the cylinder is given by [tex]V=\pi r^2h[/tex]

Consider r be the radius of the circle

[tex]\Rightarrow 1271.7=\pi r^2\cdot 5\\\\\Rightarrow r^2=\dfrac{1271.7}{3.142\times 5}\\\\\Rightarrow r^2=80.948\\\Rightarrow r=8.99\approx 9\ ft[/tex]

Thus, the radius of the cylinder is [tex]9\ ft[/tex]

Answer:

A. The number of sit-ups is 5 more than twice the number of push-ups he does.

Step-by-step explanation:

Expressions:

p = push-ups done

2p + 5 situps = total situps

2p means that he does twice the amount of situps than he did as pushups.

+ 5 situps means that he does an extra 5 situps

Answer:

The friend caught the ball at 2 feet.

Step-by-step explanation:

1. False; the ball was not still in the air at 1 second the x-component of the vertex is 0.5.

2. False; the x-component of the vertex is 0.5

3. True; the ball was tossed at a height of 2 feet (when x=0, y=2), it is safe to assume the ball was caught at the same height.

4. False; when x = 0, y = 2.

Answer:

Since in this option the minute is paid at $ 0.40, the best option is 10 minutes for $ 4.

Step-by-step explanation:

Since four friends, Abe, Bob, Carl, and Darrel, are going to a fun park, and they want to ride go-karts, and the price to ride the go-karts is $ 2.15 for 5 minutes, $ 4.00 for 10 minutes, or $ 6.75 for 15 minutes, to determine which price is the best deal, the following calculations must be performed:

2.15 / 5 = 0.43

4/10 = 0.40

6.75 / 15 = 0.45

Therefore, since in this option the minute is paid at $ 0.40, the best option is 10 minutes for $ 4.

Answer:

A. -8x⁴y³ - 6x³y⁴ + 10x²y^6

Step-by-step explanation:

Given:

– 2x²y³ ( 4x² + 3xy – 5y³)

Open the parenthesis

= (– 2x²y³ * 4x²) + (– 2x²y³ * 3xy) - (– 2x²y³ * 5y³)

= -8x⁴y³ + (-6x³y⁴) - (- 10x²y6^6)

= -8x⁴y³ - 6x³y⁴ + 10x²y6^6

The correct answer is

A. -8x⁴y³ - 6x³y⁴ + 10x²y^6
