Answer:
6
Step-by-step explanation:
H is proportionate to L, meaning that they can be represented as a ratio, 
.
If we know that L in the same ratio is 20, we can set these ratio's equal to each other to find H.
.
To find x, we can cross multiply.
So 
, meaning that when 
, 
.

Answer:
200.96
Step-by-step explanation:
Area is
Where r is the radius, we can find the radius since the radius is half of the diameter. Since the diameter is 16, the radius is 8. Now let plug it in the equation.
Which equals
Use 3.14 as pi then multiply
Which is 200.96
40, because 6×4=24 and 10×4=40
Answer:
the height of the water in the pool is 2m
Step-by-step explanation:
This problem bothers on the mensuration of solids.
Given data
Volume of pool v= 270m³
Base length l= 15m
Base width b= 9m
Height h=?
The pool takes the shape of a rectangular prism
The expression for the volume of the pool is
v= l*b*h
Substituting our given data we have
270= 15*9*h
270= 135h
h= 270/135
h= 2
Therefore the height h =2m
Answer:
C. 14xy - 6y²
Step-by-step explanation:
The distributive property will essentially result in the sum of the product of the "outside term" with each of the "inside terms".
Here, the "outside term" is 2y and the "inside terms" are 7x and -3y. So:
2y(7x - 3y) = 2y * 7x + 2y * (-3y) = 14xy - 6y²
The answer is C.
