Last week, Max earned a total of $162 working at two jobs. He worked 6 hours at his grandfather's store and 10 hours at the loca
VMariaS [17]

The choices are missing but we can find the right equation from the given information

The equation that models this situation is 6 g + 10 m = 162

Step-by-step explanation:

The given is:

  • Max earned a total of $162 working at two jobs
  • He worked 6 hours at his grandfather's store
  • He worked 10 hours at the local  movie theater
  • g represents the hourly rate paid by Max's grandfather, and m represents the hourly rate paid by the movie theater

We need to write an equation models this situation

∵ g represents the hourly rate paid by Max's grandfather

∵ He worked 6 hours at his grandfather's store

∴ He earned from his grandfather = 6 × g = 6 g dollars

∵ m represents the hourly rate paid by the movie theater

∵ He worked 10 hours at the local  movie theater

∴ He earned from the local  movie theater = 10 × m = 10 m dollars

Add 6 g and 10 m to find his total earning

∵ His total earning = 6 g + 10 m

∵ Max earned a total of $162

- Equate his total earning by 162

∴ 6 g + 10 m = 162

The equation that models this situation is 6 g + 10 m = 162

Find the measure of . (to the nearest tenth) PLEASE I NEED HELP :((​
Kobotan [32]

Answer:

Step-by-step explanation:

This is classic right triangle trig.  First decide how each side is related to the angle theta.  The side 7.7 is opposite the angle theta, while the side 14 is adjacent.  That is the tangent ratio by definition.  Setting up the tan ratio:

tan\theta=\frac{7.7}{14}

To find a missing angle on your calculator, hit the 2nd button, then the tan button and enter in 7.7/14 and hit enter.  You should get an angle measure of 28.8°

If you did not get 28.8 then you are probably in radians.  Check it in the "mode" of your calculator.
