Answer:

  p = 55 + 35h

Step-by-step explanation:

Let p and h represent the price of the service call and the hours worked, respectively. The price charged is 35 dollars for each hour, so the time-based part of the price is 35h. The base fee of 55 dollars is added to that for a total price of ...

galina1969 [7]

Answer:

Step-by-step explanation:

Ok let start by putting a set amount of hats, let start with 12, 8 times 12 equals 96, 200-96 is 104… I would subtract 8 until you get a number you can divide equally by 10, 104-8=96, 96-8 =88 , 88-8=80, there is 80 dollars left! Ok 80 divide by 10 = 8 so

8 shirts and we’ll we started at 12 and then we add how many more time we subtracted 8 so 15 total,

So, in total 8 shirts and 15 hats!!!

I need help with these two trigonometry problems.
Sloan [31]

Answer:

B \approx 32.1\°; A \approx 39.0\°

Step-by-step explanation:

Sine theorem: in any triangle, the ratio between a side and the sine of the opposite angle is constant

\frac{sin\ \alpha}a = \frac{sin\ \beta}b =\frac{sin\ \gamma}c

In our case, for the left triangle,

\frac {sin\ 103\°}{11} =\frac{sin\ B} 6 \rightarrow sin\ B = \frac6{11} sin\ 103\°

Time to grab a calculator and crunch numbers. Double check your calculator is in degrees and not in radians (plug in sin 30°, if you're getting 0.5 you're good) and you will get

sin\ B \approx 0.53 \rightarrow B \approx 32.1\°

Same difference with the right triangle. With the same calculations

sin\ A = \frac{26}{41} sin 83\° \approx 0.68 \rightarrow A \approx 39.0\°
