Answer:
5 hours
Step-by-step explanation:
The volume of the pool is ...
V = LWH
V = (10 ft)(8 ft)(5 ft) = 400 ft^3
At the given fill rate, the time it will take is ...
(400 ft^3)/(80 ft^3/h) = 5 h
It will take 5 hours for the pump to fill the pool.
Answer:
Im pretty sure the answer is 5 hours
Step-by-step explanation:
The capacity of swimming pool is
v = 10 ⋅ 8 ⋅ 5 = 400 cubic feet
The pump fills 80 cubic feet in 1 hour
Therefore, the pump will fill
400 cubic feet in 5 hours.
HELP please ASAP. I am being timed, and I am very confused on these two questions, answering both questions would be really appreciated...

Find the midpoint of A and B where A has coordinates (-7, 1)
and B has coordinates (3,-5).
Answer:
A (-7, 1) = (X1, Y1)
B (3, -5) = (X1, Y2)
Now,
Mid point = (X1 + X2÷2, Y1 + Y2 ÷ 2)
= {-7+3÷2, 1+(-5)÷2}
= (-4÷2, 1-5÷2)
= (-4÷2, -4÷2)
= (-2, -2)

Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price. The shoe store’s clerks are paid on commission. If the clerk receives a 12% commission on total purchase amounts before tax is applied, how much would the commission be for Isaac’s purchase with and without a coupon?

Write an equation in point slope form of the line that passes through the point -4, 5 and has the slope of one.
Answer:
y - 5 = x + 4
Step-by-step explanation:
Use point slope form, y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line
Plug in the given point and slope:
y - y1 = m(x - x1)
y - 5 = 1(x + 4)
Simplify:
y - 5 = x + 4
So, the point slope form of the line is y - 5 = x + 4

Hey you! Yes you! You are awesome! Can you help me?
Answer:
a = -40
Step-by-step explanation:
In order for a system of equations to have infinitely many solutions, the equations must have the same line when graphed. Knowing this, it also means that the equations equal the same thing - they're just written differently. Also, remember that a constant term is just a number with no variables.
First, I would organize the second equation into standard format just like the first one (moving the x and y terms to the left side):
[tex]6x = 16 + a -15y\\6x + 15y = 16 + a[/tex]
Then, by comparing the x and y terms in both equations, we can see that the second equation is just the first equation multiplied by 3. (Notice how 2x times 3 is 6x, and 5y times 3 is 15y.) So, we would need our constant on the left hand side to do the same, to equal -8 times 3, or -24.
Thus, we would need to find what added to 16 equals -24, and we can do this with a simple algebra equation:
[tex]a + 16 = -24\\a = -40[/tex]
Therefore, a would need to equal -40 in order for the system to have infinitely many solutions.

45 girls tried out for the field hockey team. 20% of the girls who tried out did not make the team. How many girls did not make the team?
It lagged earlier when I first asked
Answer:
9 girls did not make the team
Step-by-step explanation:
20*45=900
900/100=9
Answer:
9 girls didn't make the team
Step-by-step explanation:
The person above did it a great way, and that is the way I use it, but if you want a method that involves fractions here it is: 20% is the same as 1/5. Since there are 45 girls total, we need to find 1/5 of 45 and you can achieve that by multiplying 45 by 1/5 and you get 45/5 which is 9. Hope this helped :) .

A family of two adults and three children went to a water park. Admission to the water park costs $18 per person. Nora used the expression 2(18)+3(18) to model the total cost for the family, and Alex used the expression 5(18). Which property of operations makes both of their expressions correct? O associative property O commutative property O distributive property identity property
Answer:
distributive property
Step-by-step explanation:
5(18)=2(18)+3(18)
Distributive property
c(a+b) = ca+cb
We are using the left hand side and adding a+b
18(2+3) = 2* 18+ 3*18
18*5 = 2* 18+ 3*18

Step-by-step explanation:
But there are 2 ways to think of it becaue=se if u used the people in the school to play on the stage there are still 300 seats left or your teacher would think of it as being 300-89=211 so this word problem has 2 answers!

Help pls I’m in trouble I need this
Answer:
We conclude that:
g(-3) = 3.5Step-by-step explanation:
Some background Concepts:
From the graph, it is clear that at x = -10, the graph intersects the x-axis.
So, the x-intercept of the graph is (-10, 0).
It means g(-10) = 0
From the graph, it is clear that at y = 5, the graph intersects the y-axis.
So, the y-intercept of the graph is (0, 5).
It means g(0) = 5
Determining g(-3):
From the graph, it is clear that at x = -3, the value of the function output = 3.5.
In other words,
at x = -3, g(-3) = 3.5
Therefore, we conclude that:
g(-3) = 3.5Haley and mia's dad said if they combined the money they've saved. He would double it.

A music store buys instruments and then sells them for 30% more than they paid.
During a 20% off sale, the store offers a clarinet for $93.60.
How much did the store pay for the clarinet?
$93.60 x 0.2 = $18.72
$93.60 + $18.72 = $112.32 = Price before 20% discount.
$112.32 ÷ 100 x 30 = $33. 696 = Discount of 30%
$112.32 - $33.696 = $78.624 = Original Price
Therefore, the store paid $78.624 for the clarinet before the 30% markup and 20% discount.
It's just a process of working backwards.
