Because the denominators will always stay the same, no matter what. If they are the same, they will remain the same; however, if they are different, they will be changed to be the same before the numerator is considered.
Answer:
The height of the water is
Step-by-step explanation:
step 1
Find the volume of the tank
The volume of the inverted right circular cone is equal to
we have
substitute
step 2
Find the 25% of the tank’s capacity
step 3
Find the height, of the water in the tank
Let
h ----> the height of the water
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
substitute
where
r is the radius of the smaller cone of the figure
h is the height of the smaller cone of the figure
R is the radius of the circular base of tank
H is the height of the tank
we have
-----> volume of the smaller cone
substitute
Simplify
Y=1/4x - 1 since the y intercept is at -1
Answer:
$3,852
Step-by-step explanation:
Total for 4th grade: 2,124
5th grade: raised 396 less
2,124-396= total amount 5th graders raised
2,124-396=1,728
2,124+1,728=3,852
They raised $3,852 dollars.
Can't tell with graph but if the width is 15 more than likely the length is 13 but that is if you use the basic subtraction.
