and wants to know what is the minimum number of cups she needs in order to fill the fishbowl.
Answer:
Dixie Cup Volume = π • r² • height
volume = PI * 4^2 * 15
Dixie Cup Volume = 753.9822368616 cubic cm
Sphere Volume = 4/3 • π • r³
Fishbowl Volume = 4/3 * PI * 37.5^3
Fishbowl Volume = 220,893.233 cubic cm
She'll need this many Dixie Cups (220,893.233 / 753.982)
= 292.96 Which rounds to
293 Dixie Cups
Step-by-step explanation:
The height of the rocket after 6 seconds is 630 feet
Given the polynomial function that represents the height of the rocket expressed as:
f(t) = -16t^2 + 200t + 6
If the time the rocket take to rise is 6 seconds, hence;
f(6) = -16(6)^2 + 200(6) + 6
f(6) = - 576 + 1200 + 6
f(6) = 630 feet
Hence the height of the rocket after 6 seconds is 630 feet

The remaining side length (L) of the rectangle is approximately 3.335 units.
To find the remaining side length (L) of a rectangle when given the perimeter and three sides of the rectangle, we can use the formula for the perimeter of a rectangle:
Perimeter = 2 * (Length + Width)
In this case, you have three sides, which means you have the sum of two lengths and one width:
3 * Side = 2 * Length + Width
Given that the perimeter is 30 and the three sides sum up to 70:
30 = 2 * Length + Width
We also know that 3 * Side = 70, so each side is equal to 70/3 = 23.33 (approximately).
Now, we can substitute this value for Width into the first equation:
30 = 2 * Length + 23.33
Subtract 23.33 from both sides:
30 - 23.33 = 2 * Length
6.67 = 2 * Length
Divide by 2 to isolate Length:
Length = 6.67 / 2 = 3.335
So, the remaining side length (L) of the rectangle is approximately 3.335 units.

Opposite sides equals to 7 and so you add 7 + 7 which equals to 14. Next you subtract 30 by 14 to get the total of the opposite side of L and itself which gets you 16 which is then divided by 2 because you have L and its opposite side which would give you 8. So L equals to 8.
Check:
7 + 7 + 8 + 8
14 + 16

Equation: y=8.5h+25 Answer: $50.50
Step-by-step explanation:
h= amount of hours
y=total cost
y=8.5h+25
She rented for 3 hours
y=8.5(3)+25
y=25.5+25
y=50.5
