Answer:
The height is 36 in
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a rectangular based pyramid.
Step one
Given data
Volume v = 1944 in
length of base l = 18 in
width of base w = 9 in
Height h= ?
Step two
we know that the expression for the volume of a pyramid is given as
![volume=\frac{ lwh}{3}](https://tex.z-dn.net/?f=volume%3D%5Cfrac%7B%20lwh%7D%7B3%7D)
substituting our given data we have
![volume = \frac{18*9*h}{3} \\volume = \frac{162h}{3} \\volume= 54h](https://tex.z-dn.net/?f=volume%20%3D%20%5Cfrac%7B18%2A9%2Ah%7D%7B3%7D%20%5C%5Cvolume%20%3D%20%5Cfrac%7B162h%7D%7B3%7D%20%5C%5Cvolume%3D%2054h)
but volume = 1944 in therefore
![1944= 54h\\h= \frac{1944}{54} \\h= 36 in](https://tex.z-dn.net/?f=1944%3D%2054h%5C%5Ch%3D%20%5Cfrac%7B1944%7D%7B54%7D%20%5C%5Ch%3D%2036%20in)
Answer:
20
Step-by-step explanation:
The ratio of adults to kids is 10:4
Likewise, 50:20 when simplified is a ratio of 10:4

Answer:
2.98×10^-6 hrs
Step-by-step explanation:
Speed = Distance/Time
Time = Distance/speed
Given
Distance = 17in
Speed= 90mph
Convert inches to miles
1in = 1.578 × 10-5 mile
17in = 17(1.578 × 10-5) mile
17in = 26.826×10^-5miles
Get the time
Time =26.826×10^-5/90
Time = 0.298×10^-5
Time = 2.98×10^-6 hrs
