Answer:
≥ 420 boards
Step-by-step explanation:
Write the required relation between cost per board and "x" (the number of boards that must be sold).
143 + 30240/x ≤ 215 . . . . . . . note that the first term is <em>not</em> 143x
Subtract 143
30240/x ≤ 72
Multiply by x/72. This is a positive number because x is a positive number.
30240/72 ≤ x
420 ≤ x
At least 420 surfboards must be sold to limit the final cost per board to $215.
Answer: 527.79 m²
Step-by-step explanation:
formula is A = 2πrh + 2πr²
A = 2π x 4 x 17 + 2π x 4²
A = 527.79 m²
So yuo simplyfly
15:20=3:4
6:8=3:4
8:12=2:3
9:12=3:4
so your answer is not c
