There's two ways to do this problem: y=mx+b and normal division. To divide, just do 390 ÷ 40 and 234 ÷ 24. Both equations should equal 9.75. The other way is a bit more complicated, but it's the way I solved it. They give you two points, (24,234) and (40,390). 10 is b, now to find the slope. To find the slope you do y2-y1 over x2-x1. Plug the numbers in: 390-234 over 40-24. Simplify: 156/6, which equals 9.75. So, y=9.75x+10. The answer is: after 10 hours of work, she'll make $9.75

Cos 12 = sin (90 - 12) = sin 78
Answer B shows the correct information. If you look at the totals of the tables, B shows that 30 aren't in a band, 20 are in a band, and 25 play an instrument.
Answer:
Your tip would be $6.60
Step-by-step explanation:
Here, One angle magnitude = 58 [ Given ]
Opposite angle = 90 - 58 = 32 [ Complementary angles ]
One angle = 90
Now,
Tan Ф = P/B
Tan 58 = 14/EF
EF = 14/1.60
EF = 8.75
& Sin Ф = P / H
Sin 58 = 14/DF
DF = 14/0.84
DF = 16.50
Hope this helps!
