Answer:
89
Step-by-step explanation:
To find the area of the rectangle, you do 13 times 8. That gives you 104. Now, for the triangle, you do 1/2 base times height. That is 1/2 of (13 - (4 + 4)) times 6. That equals 1/2 of 5 times 6. So 5 times 3 is 15. 104 - 15 is 89. I hope this helped and please mark me brainliest! Thanks.
Step-by-step explanation:
the volume of pyramid =
⅓× base area × height =
⅓× (½×7×5)×6 =
1/6 × 210 = 35 cm³
C = 25 + 7h...c = 81
81 = 25 + 7h
81 - 25 = 7h
56 = 7h
56/7 = h
8 = h......so at 8 hrs, it will cost $ 81
15 is a positive value, -3 is a negative value.
A positive value is always greater than a negative value.
The answer is: 15 > -3
