Sum of all exterior angles = 360°.
Number of sides = 360 ÷ 40 = 9
Each interior angle = 180 - 40 = 140°.
Answer: <span>The regular polygon has 9 sides and each of its interior angles 140°</span>
Hello!
A cereal box is a rectangular prism
The equation to find the surface area of a rectangular prism is
2(wl + wh + lh)
The length is 11
The width is 8
The height is 6
Put in the values
2(8 * 11 + 8 * 6 + 11 * 6)
Multiply
2(88 + 48 + 66)
Add
2(202)
Multiply
404
The answer is 404 inches squared
Hope this helps!
When they work together, it takes John 1/x hours and it takes Brian 1/(x+15) hours to complete 1/4 of the model.
1/x + 1/( x+15 ) = 1/4 / · x ( x+15 )
x+15 + x = x ( x+15 ) /4 / · 4
8 x + 60 = x² + 15 x
x² + 15 x - 8 x - 60 = 0
x² + 7 x - 60 = 0
x² + 12 x - 5 x - 60 = 0
x · ( x + 12 ) - 5 ·( x+ 12 ) = 0
( x + 12 ) · ( x - 5 ) =0
x = - 12 ( not accepted ) or x = 5
The time taken by Brian: 5 + 15 = 20 hours
