Answer:
There were total 2900 seats in the theater.
Step-by-step explanation:
Given that:
Seats filled by students = 1247 seats
Vacant seats = 57%
Total percentage of seats = 100%
Percentage of seats filled by students = (100-57)%
Percentage of seats filled by students = 43%
Let,
x be the total number of seats.
43% of x = 1247
![\frac{43}{100}x=1247\\0.43x=1247](https://tex.z-dn.net/?f=%5Cfrac%7B43%7D%7B100%7Dx%3D1247%5C%5C0.43x%3D1247)
Dividing both sides by 0.43
![\frac{0.43x}{0.43}=\frac{1247}{0.43}\\x=2900](https://tex.z-dn.net/?f=%5Cfrac%7B0.43x%7D%7B0.43%7D%3D%5Cfrac%7B1247%7D%7B0.43%7D%5C%5Cx%3D2900)
Hence,
There were total 2900 seats in the theater.
Answer:
x = 10 ft
Step-by-step explanation:
By Pythogorus theorem,
x^2 = 8^2 + 6^2
x^2 = 64 + 36
x^2 = 100
x = sqrt(100)
x = 10 ft

Answer:
r = 6 cm
Step-by-step explanation:
The volume of a sphere is 288 pi cm tripled . Find the lenght of a radius of a SPHERE.What is the answer and how did you do it?
-------------------
The volume of a sphere of radius r is:
V+=+4%2Api%2Ar%5E3%2F3
It's r cubed, not tripled. meaning r*r*r
-------------------
288pi+=+4%2Api%2Ar%5E3%2F3
864+=+4r%5E3
r%5E3+=+216
r = 6 cm
