Answer:
B) 70.3
Step-by-step explanation:
You can solve this question two different ways.
One way is to find 85% of 38 by doing 38 × 0.85, which is 32.3. Then, you can add that to 38 (since 100% of 38 is 38) and get 70.3.
Another way you can find this (the easiest way) is to just find 185% right off the bat by doing 38 × 1.85 and get the answer of 70.3.
Let be Z the money ;
We have ( 40 / 100 ) x Z = $85 ;
( 4 / 10 ) x Z = $85 ;
( 2 / 5 ) x Z = $85 ;
Z = $( 85 x 5 ) ÷ 3 ;
Z = $425 ÷ 3 ;
Z = $141,66 ≈ $142 ;
Total area of the ends: 2(2")(6") = 24 in^2
Total area of the sides: 2(2")(9") = 36 in^2
Are of the bottom : 1(6")(9") = 54 in^2
Total surface area to be covered = (24+36+54) in^2
Remember, the slope formula is y2-y1 over x2-x1. To plug numbers into the formula, find two points. Then, you substitute the points into the formula.
