So you know the school donated 9 pies, so you want to know how many pieces are in 9 pies. (remember 8 pieces per 1 pie)
9 x 8 = 72
Next you subtract the amount you got to total amount.(224)
So 224 - 72 is 152.
152 is how many pieces of pie were sold by students.
To configure this number back to amount of pie, you basically need to divide by 8(number of pieces in 1 pie).
152 divided by 8 is 19. So 19 pies were sold by students.
Hope this helped!
Answer:
Slope = 8
Y-intercept = 9
Step-by-step explanation:
y=mx+b
M stands for the slope of the line
B stands for the y-intercept of the line
Answer:
yes they are proportional because they are in a line
Step-by-step explanation:
Answer:
Step-by-step explanation:
n*8<72
:8 :8
n<72/8
n<9
n could be 1,2,3,4,5,6,7,8
The surface area of a cone is : pi•r•slant height + pi•r^2
If d=28 then r=14
Use the pythagorean theorem to find the slant height c^2 = 14^2 + 22^2
C^2 = 680
C = 26.08 (rounded)
Pi•14•26.08 + 196pi = 1,762.67 squared cm
