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:
Two hundred eighty-three thousand, nine hundred eighty
Step-by-step explanation:
The coordinates of the center of this circle will be the average between the extreme points
C = ( (xo+x1)/2 , (yo+y1)/2)
Where,
xo = 3 and x1 = 9
yo = 8 and y1 = 16
Then us stay with"
C = ( (3+9)/2 , (8+16)/2)
C = ( 12/2 , 24/2)
C = ( 6 , 12 )
Answer:
![13,846\ cones](https://tex.z-dn.net/?f=13%2C846%5C%20cones)
Step-by-step explanation:
Let
x -----> the number of ice cream cones sold 5 years ago
Remember that
![100\%+30\%=130\%=130/100=1.3](https://tex.z-dn.net/?f=100%5C%25%2B30%5C%25%3D130%5C%25%3D130%2F100%3D1.3)
we know that
Sales 5 years ago, multiplied by the 30% increase should equal 18,000 ice cream cones.
so
The linear equation that represent this problem is
![1.30x=18,000](https://tex.z-dn.net/?f=1.30x%3D18%2C000)
Solve for x
Divide by 1.3 both sides
![x=13,846\ cones](https://tex.z-dn.net/?f=x%3D13%2C846%5C%20cones)
