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
The answer to your problem is 20.
<span>Rx h= ax-k
</span><span>Rxh−ax=−k
</span><span><span>x(rh−a)=−k ( here i took the common one out ..)
x = - k/ rh-a
Hope it helps !!!

Answer: 5
Step-by-step explanation:
To solve this, we would have to divide 361.42 by 79.45. This will be:
= 361.42 / 79.45
= 4.549
We can see that 4.549, has 4 significant digits. By the time we round it off to 1 significant number, we would have 5.
