The side lengths of the pool 10 ft and 45 ft.
<u>SOLUTION:
</u>
Given, a rectangle swimming pool is 8 feet deep.
One side of the pool is 4.5 times longer than the other.
Let the length of pool be n feet, the width will be 4.5n feet
The amount of water needed for the swimming pool is 3600 cubic ft
We have to find the dimensions of the pool. Now, we know that,
On taking square root on both sides we get,
So, the width will be 
To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.
15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been
The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20
So take the 21 from before, and if you add -1, you get 20!
So, x= ➖1⃣!!!!!!! (That's a -1)
Step-by-step explanation:
(39 + 33) - 94
39 + 33 = 72
94 - 72 =22
Answer:
B
Step-by-step explanation:
because TRUST ME
5+7+8=20 which is the total number of balls that the bag contains
because out of the 20 balls only the 8 are blue, it is right to say that
8/20 = x/100 ⇒ x= (8·100)/20 ⇒ x= 800/20 ⇒ x=40
the blue balls are the 40%
