Four friends, Abe, Bob, Carl, and Darrel, are going to a fun park .They want to ride go-karts. The price to ride the go-karts is $2.15 for 5 minutes,$4.00 10 minutes ,or $6.75 for 15 minutes .Which price is the best deal?Explain why? math question
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.

Find the volume of the cone using 3.14 for pi. Please help asap i need it!
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.

Quicklyyyy please
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

Can I have help :< Im stuck and confused
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
Ayaan does push-ups and sit-ups every morning. He does p push-ups and 2p + 5 sit-ups. Which statement describes the number of sit-ups Ayaan does every morning?
The number of sit-ups is 5 more than twice the number of push-ups he does.
The number of sit-ups is 5 more than half the number of push-ups he does.
The number of sit-ups is 5 fewer than twice the number of push-ups he does.
The number of sit-ups is 5 fewer than half the number of push-ups he does.
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

Identify the vertex of the graph. Tell whether it is a minimum or maximum.
A. (–2, 1); minimum
B. (–2, 1); maximum
C. (1, –2); minimum
D. (1, –2); maximum
Answer:
C. (1, –2); minimum
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The vertex is the turning point of the graph.
This is at (- 1, - 2)
The graph changes from decreasing to increasing at (- 1, - 2)
Hence is a minimum at (- 1, - 2)
find the area of the figure with coordinates A (-6,1), B (2,1), C(-3,4), D(5,4)
Answer: The area of the figure is 24 units.
Step-by-step explanation:
After plotting, the given points on the graph, we can observe that it is a parallelogram(opposite sides are equal and parallel)
Height = 4-1 = 3 units
Base = 2-(-6) = 8 units
Area of parallelogram = Base x height
= 8 x 3 square units.
= 24 square units.
Hence, the area of the figure is 24 units.

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.
