First recognize that the unit rate we're finding is gallons per hour, or
.
rate for Tank 1 = x gallons per hour = <em>a</em> gallons / <em>b</em> hours

Answer:
40%
Step-by-step explanation:
In order to find percent, you can set up the fraction 2/5 to the equation x/100.
Then solve using algebra to cross-multiply.
so the answer is 40%.
Vsphere=(4/3)pir³
d/2=r
given
d=4
d/2=r=4/2=2
Vsphere=(4/3)pi2³
Vsphere=(4/3)pi8
Vsphere=32/3pi
using pi=3.14
Vsphere=33.493333333333 cm³
round
Vsphere=33 cm³
You can use the ratio to find the height of the actual building, 1 inch:25 feet.
We have to find y which is the actual height, 12.5 inches: y.
To find y, you have to multiply 12.5 by 25 to find the actual height.
12.5×25= 312.5
So the actual height of the building is 312.5 feet.
