Answer:

Step-by-step explanation:

We can first look at the number that is higher.

16 is negative because it is the number that is higher and is being subtracted from 12.
So your answer is

Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.
Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
23.) 21 hrs at $ 11 per hr = (21 * 11) = 231....and u received 91% of ur wages...
0.91 (231) = 210.21
fraction u got : 210.21 / 231 = 0.91 = 91/100 <== I am not 100% sure on
this. I might be making this harder then it looks....u r going to get 210.31 take home pay.....or 91% which in fraction form is 91/100
26B. 17/10 = 85/ x
cross multiply
17x = 850
x = 850/17
x = 50....50 liters of oil <==
26C. 12:9...added = 21
12/21(4200) = 50400/21 = 2400 <== higher cost receives 2400
9/21(4200) = 37800/21 = 1800
