The number of charts that was coded per hour will be:
(number of charts)/(time taken)
number of charts=23 charts
time taken=7.5 hours
thus the rate will be:
23/7.5
=3.06666667
~3 charts per hour (to the nearest whole number)

I have the other two answers. i just need the maximum height. please
Alex777 [14]

You have the maximum height happens at 5 seconds.

Replace t with 5 and solve for h(t):

h(5) = -0.2(5)^2 + 2(5)

h(5) = -0.2(25) + 10

h(5) = -5+10

h(5) = 5

The maximum height is 5 feet.

Part 1

Divide bags of sand by gallons of water:

14 /6 = 2.33

21/9 = 2.33

The ratio is the same, so this means for every gallon of water you need 2.33 bags of sand.

Convert the fractions into decimals and you will get 7/3 = 2.33

The answer for Part 1 is D) 7/3

For part 2, multiply the gallons of water by 2.33 to get the number of sand bags needed:

12 x 2.33 = 27.99, which rounds to 28.

The answer is C) 28 bags.
