Answers
Answer:
3 inches
Step-by-step explanation:
25*20*h=750
500h=750
h=1.5
Height*2 = length of one of the cut corners
1.5*2=3
Therefore, 3 inches
Answer:
5 in
Step-by-step explanation:
x = number of in cut from each side
V = 750
V=lwh
l = 25 -2x
w = 20-2x
h =x
V = (25-2x)(20-2x)x
(25-2x)(20-2x)x = 750
4x^3-90x^2+500x-750=0

Each visit to a water park costs $19.95. An annual pass to the park costs $89.95. Write an inequality to represent the number of times you would need to visit the park for the pass to be a better deal. Use x for your variable. Do not use $ in the awnser pls help
Answers
Answer:
4.5
Step-by-step explanation:
Answer:
It would be 4.7342 times to get the park pass
Step-by-step explanation:
x > (89.95/19.95)
x is the number of times you will have to visit the park in order to get a better deal.
____________________________________________________________
I'm assuming you want to know how many times you have to visit the park for the pass to pay off...
Let's say that "x" is the number of times you visit the park. So.
19.95x = 89.95
Divide both sides by 19.95 to get "x" alone
x = 4.509
We round the number to the nearest whole and...you'd have to go to the park at least 5 times.
