Answer:

  57.9°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between trig functions and sides of a right triangle. Here, you're given the side adjacent to the angle of interest, and the hypotenuse of the triangle. This suggests the CAH relationship is the one of interest:

  Cos = Adjacent/Hypotenuse

  cos(angle) = (741 ft)/(1393 ft)

  angle = arccos(741/1393) ≈ 57.863° . . . . . use the inverse cosine function

  angle ≈ 57.9°

The wire makes an angle of approximately 57.9° with the ground.

Andre owned a 1/4 acre lot. He wanted to construct a 120’ x 80’ tennis court on the lot. How many square feet will remain uncove
OLga [1]

The area of the tennis court is computed by multiplying the dimensions given,

                               A = 120' x 80'

                               A = 9600 ift


Then, we convert the area in ft² to acres,

                       A = (9600 in²)(2.3 x 10^-5/ 1 in²)

                           A = 0.24 acre


The portion of land remaining is,

                  A of remaining = 0.25 acre - 0.24 acre

                                           = 0.1 acre


The remaining portion is for Andre's studies.


This, 0.1 ft² is equal to the 4% of the given area of the court.

If randy earns $12.74 per hour, what is his overtime rate? How much should randy make if he works 45 1/2 hours during 1 week?
elena-14-01-66 [18.8K]

Answer:

$19.24 is the overtime rate $579.67 one week

Step-by-step explanation:

So $13.00 its $19.50 so I subtracted $12.74 to $13.00 got 0.26 then subtracted $19.50 by 0.26 and got $19.24

$12.74 times 45.5 that will be $579.67 for just one week

If I didn't get it right. Tell me in the comments. I think I got it right.
