Answer:
Length is 22.5 ft
Width is 16.5 ft
Step-by-step explanation:
4L-w=73.5
4L=73.5+w
L=(73.5+w)/4
P=78
P=2L+2w
78=2[(73.5+w)/4]+2w
78=(73.5+w)/2+2w
78=(73.5+w+4w)/2
2•78=73.5+5w
156=73.5+5w
156-73.5=5w
82.5=5w
82.5/5=w
16.5=w
L=(73.5+w)/4
=(73.5+16.5)/4
=90/4
L=22.5

Answer:
h = 5 and k = -8.
Step-by-step explanation:
The parent equation is f(x) = x², which is the equation of a parabola having the vertex at point (0,0).
The original equation is given by g(x) = (x - 5)² + k, ⇒ y = (x - 5)² + k
⇒ y - k = (x - 5)²
So, the vertex of the original equation is at (5, k) which is given to be (5, -8)
Therefore, h = 5 and k = -8. (Answer)
Answer: 10 minutes
Step-by-step explanation:
First you have to find out how big the tank is. You will have to you the formula Length x Width x Height. 20 x 18 x 10= 3,600 in. Then you would divide that by 360. 3,600/360= 10. It would have to take 10 minutes to empty the aquarium.
