Answer: Im not completely sure but I believe its 20
Step-by-step explanation: The way I did it is kind of hard to explain.
Divide the numerator and denominator by 21:
21 / 21 = 1
84 / 21 = 4
So 21/84 is equal to 1/4.
The answer would be 6 inches!
Answer:
A. D: 0 ≤ b ≤ 10 R: 0 ≤ W(b) ≤ 120
Step-by-step explanation:
Since b represents the number of birdhouses, it is reasonable for that to have non-negative values. The maximum material availability means that b > 10 is not of practical use. This eliminates choices B and D.
Since W represents the amount of wood required for b birdhouses, it is reasonable for the range of it to match 12 times the domain: 12·0 = 0 to 12·10 = 120. This eliminates choice C.
The appropriate choice is ...
A. D: 0 ≤ b ≤ 10 R: 0 ≤ W(b) ≤ 120
