Step-by-step explanation:
Given :
Mean :
![$=-0.0375 \left[ \frac{t^4}{4} \right]^4_0 + 0.225 \left[ \frac{t^3}{3} \right]^4_0$](https://tex.z-dn.net/?f=%24%3D-0.0375%20%5Cleft%5B%20%5Cfrac%7Bt%5E4%7D%7B4%7D%20%5Cright%5D%5E4_0%20%2B%200.225%20%5Cleft%5B%20%5Cfrac%7Bt%5E3%7D%7B3%7D%20%5Cright%5D%5E4_0%24)
= 2.4

The lateral area is the area of all the sides except the base. So you find the area of the triangles (16), then the left rectangle (80), then the right rectangle (90). Finally you add them together.
16+16+80+90=202
Rounding 1.49 to the nearest tenth would make it 1.50
As a fraction 0.50 is 1/2 so 1.50 becomes 1 1/2
He pays $86.70 for the carpet. 8 time 10.2 equals 81.6.
10.2 divided by 2 equals 5.1. you will use 5.1 later.
81.6 + 5.1 = 86.7
