Answer:
180 gallons
Step-by-step explanation:
Each hour, 8 gallons were lost. Thus, in 6 hours,
6 * 8 = 48 gallons were lost
After 6 hours, 132 gallons remained, so before this 6 hours, there were more 48 gallons in it. Thus,
Original amount was 132 + 48 = 180 gallons
Originally, 180 gallons of water was in the pool
Answer:
y =x^2 +8x +15
factories form
y =( x+5 )( x+3 )
x intercept where the graph meet the x axis
y = x^2 +8x +15
let y =0
0 = x^2 +8x +15
0 = ( x + 5) (x+3)
o = x+5 or 0 = x+3
-5 = x or x = - 3
x intercept
(-5;0)
(-3 ;0)
axis of symmetry : where you will cut the graph into two half
x = - b/2a
x = - 8/2(1)
x = - 8/2
x = - 4

The answer is 37.45
Explanation:
.07x35=2.45 2.45+35=37.45
Answer: 5 cm by 10 cm gives an area of 50 cm^2
To do this draw a parallelogram and start by labeling the base as 10 cm. If 10 cm is the base, then the height needs to be 5 cm.
To find the area, multiply the base times height.
This will give you: 5 x 10 = 50 which is less than 60.
