Answer: 30
Step-by-step explanation:
3(0.3m + 6) + m =75
(0.3 x 3 = 0.9)
(6 x 3 = 18)
0.9m + 18 + m = 75
0.9m + m + 18 = 75
(m=1)
1.9m + 18 = 75
1.9m = 75 - 18
1.9m = 57
m = 57÷ 1.9
m = 30
Answer:
area of shaded region =(6×4)²-4(π6²)=123.61in²
Answer: x = 1
3x + 4 = 7
subtract 4 from both sides
3x = 3
x = 3/3 = 1
Answer: 126 in
Step-by-step explanation: 126 in because if you were to seperate the shapes you would get 6 in for the triangle by using the formula A=1/2 bh and for the rectangle you would get 120 by using the formula A=bh and when you add it you will get 126 in.
Surface area is 6s^2, so 6(7^2) is 294. The minimum amount would be 294 inches^2 of wrapper paper.
