Okay. So no more than 660 minutes will be spent cutting the lawn. The sign will be less than or equal to. A and D are out, because those show greater than or equal to symbols, which is not what we're looking for. x represents the number of lawns mowed, which is an average of 40 minutes, and he will have done 110 minutes. The equation is 40x + 110 ≤ 660. The answer is C.

How many nanoseconds does it take for a computer to perform one calculation if it performs calculations per second?

igor_vitrenko [27]

I believe the correct question is:

6.7*10^7 calc/sec?

So:

1/(6.7 x 10^7) = seconds per calculation

1/(6.7 x 10^7) = 100/(6.7 x 10^9) = 14.9 x 10^-9 seconds per calculation = 14.9 ns

Which is approximately 15 ns

Answer:

15 ns

A volleyball reaches its maximum height of 13 feet, 3 seconds after its served. Which of the following quadratics could model th

julsineya [31]

Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.

We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.
