That's a rectangular prism.
And the formula to find the volume of a rectangular prism is:
Plug in what we know:
Multiply the three numbers together:
Answer: y = -5
Substitute in 3 for x.
x - y = 8 Substitution
3 - y = 8 Subtract 3 from both sides
-y = 5 Divide by -1 to both sides
y = -5 Answer!
You can also check your work.
x - y = 8
3 - (-5) = 8
3 + 5 = 8
8 = 8
A ) The angle formed by 2 consecutive radii:
Ф= 360° : 8 = 45°
b ) The angle formed by a radius and a side of a polygon:
α = (180° - 45°): 2 = 135° : 2 = 67.5°
Answer:
B ) 45°, 67.5°
Divide 2.48 by 10 to find the price of 1 slice. = 0.248
Do the same with the other price.
3.18 / 12 = 0.265
The best one to get would be the 10 cheese slices because a single slice is cheaper than the single slices for the 12 slices.
hope this helped! (:
