Mariana's swimming pool holds 22,000 gallons of water. If there are approximately 7.5 gallons per cubic foot, what size swimming pool, in terms of cubic feet, does Mariana have? Round your answer to the nearest cubic foot.

Answers

The size of swimming pool, in terms of cubic feet, that Mariana has is 2,933 cubic feet. There are approximately 7.5 gallons per cubic foot and there are 22,000 gallons of water. Make a proportion. 7.5 gallons : 1 cubic foot = 22,000 gallons : x. Cross the products and solve for x. x = 1 cubic foot * 22,000 gallons : 7.5 gallons = 2,933 cubic feet.

Answer:

Size of Mariana's swimming pool would be 2933 cubic feet.

Step-by-step explanation:

Mariana's swimming pool holds water = 22,000 gallons

there are 7.5 gallons water per cubic foot,

Now we have to calculate the size of the swimming pool by unitary method.

∵ 7.5 gallons of water is contained = 1 cubic foot of pool

∴ 1 gallon of water will be contained in = $(1)/(7.5)$ cubic foot

∴ 22,000 gallons of water will be contained in = $(22000)/(7.5)$

= 2933 cubic feet

Size of Mariana's swimming pool would be 2933 cubic feet.

Hey i need help pleaseA week before the election, 1,500 people were asked who they planned to vote for. 45% said they planned to vote for Candidate X. 38% said they planned to vote for Candidate Y.

Answers

Answer: A subject, a verb, and a complete thought.

Step-by-step explanation:

Independent clauses have three components:

They have a subject - they tell the reader what the sentence is about.

They have an action or predicate - they tell the reader what the subject is doing.

They express a complete thought - something happened or was said.

How to show your work to solve 3r^2-16r-7=5

Answers

OK so 3r^2-16r-7=5
Subtract five from both sides
3r^2-16r-7-5=0
Add like terms
3r^2-16r-12=0
Factorise it, this means putting it into brackets
(3r + 2)(r - 6)
Find out what multiplies to make negative twelve but adds to make negative sixteen
However none of the terms do this so we put negatives next to the "r"s
(-3r + 2)(-1r - 6)
The answer is r=6

Answer:

Step 1: Subtract 5 from both sides.

3r2−16r−7−5=5−5

3r2−16r−12=0

Step 2: Factor left side of equation.

(3r+2)(r−6)=0

Step 3: Set factors equal to 0.

3r+2=0 or r−6=0

r=−2/3

or r=6

Answer:

r=−2/3
