19/40 as a fraction and decimal it is 0.475
The velocity v and maximum height h of the water being pumped into the air are related by the equation
v=
where g = 32
(a) To find the equation that will give the maximum height of the water , solve the equation for h
v=
Take square root on both sides
= 2gh
Divide by 2g on both sides
= h
So maximum height of the water h =
(b) Maximum height h= 80
velocity v= 75 ft/sec
Given g = 32
h =
h =
h= 87.89 ft
The pump withe the velocity of 75 ft/sec reaches the maximum height of 87.89 feet. 87.86 is greater than the maximum height 80 feet.
So the pump will meet the fire department needs.
Answer:
Mean = Mean is all of the numbers added up and divided by the amount of numbers you have added up. Therefore its 414 ÷ 15 = 27.6
Mode = Most common number = 35
Range = Largest number - Smallest number
40 - 5 = 35
Median = 32 (Middle number)
Answer:
25,200in²
Step-by-step explanation:
The architect wants to draw a room that has an area of 175 ft². We need to find this measurement in square inches.
<u>Square feet and square inches are different from feet and inches. </u>
We should know that a square foot is 144 square inches.
Multiply 175 * 144.
So the same architect wants to draw a room that should have an area of 25,200in².
