Answer: 512m³
Step-by-step explanation:
v = whl
The volume for left building:
v = w x h x l
v = 4 x 10 x 8
v = 320 m³
The volume for right and lower building:
v = w x h x l
v = 8 x 4 x 6
v = 192 m³
The total volume for the entire Charter School is: 320m³ + 192m³ = 512m³
First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer.
To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)
8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120.
120/4=30
It takes 30 minutes to fill the pool up to 120 gallons.

<h2>$13 </h2>
Step-by-step explanation:

cost of 2.5 pounds= $32.5
Step two:
Required
we want to find the charge per pound
if 2.5 pounds cost $32.5
1pound will cost x
cross multiply we have
x= 32.5/2.5
x=$13
The cost per pound is $13
Answer:
The markdown rate is 32.1%
Step-by-step explanation:
We can easily solve this problem by applying a rule of three,
$1.09 a dozen ---------------------------------- 100% of the value
$0.35 a dozen ------------------------------------- x
x = ($0.35/$1.09) * 100%
x = 0.3211 *100%
x = 32.11%
The markdown rate is 32.1%
