Answer:
7m
Step-by-step explanation:
v=πr^2h
769.3=3.14*r^2*5
769.3=15.7r^2
769.3/15.7=15.7r^2/15.7
49=r^2
√49=√r^2
√49=r
r=7m

1. How many cars per day does Car Mart sell? How did you use the table to find this rate?
2. How many cars per day does Winston's sell? Explain how you found this rate.
3. Which dealership sells more cars per day? How many more?
4. Which dealership started with more cars? How many more cars did that dealership start with?
Explain how you found your answer.
1. Car Mart sells 11 cars a day.
2. Winston's sells 10 cars per day.
3. Car Mart sells one more car per day.
4. Winston started with more cars.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.
Rate for cart mart is (32 - 43)/(3 - 2) = - 11.
Car Mart sells 11 cars a day.
Winston's sells 10 cars per day.
Car Mart sells more cars per day.
As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.
As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.

The original height was _answer this_ feet.
please help me with this thank you
Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
we translate word problem to equation.
8219.5 IS 85% of TOTAL
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
8219.5 = 0.85 * Total
Hence, total = [let total be 7]
8219.5 = 0.85 * t
t = 8219.5/0.85 = 9670 feet

What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The radical is the symbol that is used to represent the root in the expression n√x. When the value of n in this radical is 2, then it is known as the square root.
The inverse operation of a square root is a square, which means that the expression is needed to be multiplied by itself.
