Usually t is used for time. Plug in the correct value for t. Which is 5 hours.
w = -500(5) + 7000 ; Start
w = -2500 + 7000 ; Multiple -500 by 5
w = 4500 ; Subtract 2500 from 7000
So, after 5 hours of draining the pool, 4500 liters (I choose liters. It didn't specify in the question) of water are still in the pool.

The volume of globe is 381.51 cubic inches when the dimensions of the globe were reduced by half
<em><u>Solution:</u></em>
The globe is usually of spherical shape
<em><u>The volume of sphere is given as:</u></em>
Where, "r" is the radius of sphere
Given that diameter is 18 inches
Diameter = 18 inches
Thus radius is 9 inches
The dimensions of the globe were reduced by half
Thus radius is reduced by half
Now find the volume of sphere
Thus volume of globe is 381.51 cubic inches
First evaluate the sq root of 45.
To do so, you have to find perfect square factors (2 x 2, 3 x 3, 4 x 4, and etc.)
The factors of 45 are 3 x 3 x 5.
Notice that there is a 3 x 3. That means you can get the 3 out of the square root and multiply with the number outside of the square root.
11(3)square root 5 - 4 square root 5
33 square root 5 - 4 square root 5
Subtracting and Adding square roots is the same thing as subtracting and Adding variables. If they have the same variable you can +/-. So if they have the same square root, then can +/-.
Answer: 29 square root 5
Answer:5x - 7x + 6 = -2(x - 3)
-2x + 6 = -2x + 6
0x = 0
