Answer: 4 gallons will be needed.
Step-by-step explanation:
The bottom of the pool is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = Length × width
Olympic-sized swimming pool of uniform depth measures 50 meters by 21 meters. The area of the bottom would be
Area = 50 × 21 = 1050 m²
The bottom of the pool is to be treated with a sealer, and one gallon of the sealer covers 300 square feet of surface. This means that the number of gallons of sealer required for the job would be
1050/300 = 3.5gallons Approximately 4 gallons to the nearest gallon
Answer:
the answer has to be 3(17-y)
Step-by-step explanation:
I'm pretty sure about that cause what I did at first is subtract the numbers.
<em>6</em><em>0</em><em>-3y-9</em>
=51-3y
factor our 3 from the expression.
3(17-y)
Answer:
$298
Explanation:
There are 4 friends, each of whom splits the profit equally. Since they each had a total of $184 at the end of the second month, that means the car wash had made
184(4) = 736 by the end of the second month.
Now we subtract the amount of profit in the first month:
736 - 438 = 298

Answer:
BD = 14
Step-by-step explanation:
The Pythagorean theorem can be used to find the lengths of CD and BC.
CD² +12² = 13²
CD = √(169 -144) = √25 = 5
__
BC² +12² = 15²
BC = √(225 -144) = √81 = 9
__
The length BD is then ...
BD = BC +CD
BD = 9 + 5 = 14
The length of side BD is 14 units.
Answer:
perpendicular slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (6, - 6) and (x₂, y₂ ) = (- 1, - 3)
m = 
= 
= - 
Given slope m then the slope of a perpendicular line is
= - 
= -
