Answer:
A
Step-by-step explanation:
1) y = -x + 6
2) y = x - 6
The line with a positive slope (2) crosses the y-axis (vertical line) at - 6 (positive slope line goes uphill)
The line with the negative slope (1) crosses the y-axis at 6. (Negative slope goes downhill)
You can set up an equality:
40/160 = 225/x
Cross multiply:
40x = 160(225)
Evaluate:
40x = 36000
Isolate x:
x = 900.
So, 900 batteries are required for 225 calculators.

Answer:
33.3
Step-by-step explanation:
tan A = opp/adj
tan 39° = 27/x
x tan 39° = 27
x = 27/(tan 39°)
x = 33.3
