Answer:
130 miles
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual distance = 31/4 x 40
convert 31/4 to an improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
13/4 x 40 = 130 miles
A cylinder has a height of 5 feet. Its volume is 1,271.7 cubic feet. What is the radius of the cylinder?
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]
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.
Using the unit circle, determine the value of sin(-240°).
A) -1/2
B) √3/2
C) 1/2
D) -√3/2
Answer:
B. √3/2.
Step-by-step explanation:
If we follow the circle from (1,0) clockwise through 240 degrees we end up at 120 degrees.
sin(120)
= √3/2
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. What is the price to rent a bike for 2 hours?
$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.
What is the linear system?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.

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.

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

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

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.
