For the first one, it should be 5x=50-30 which 5x=20 and x=4 so she needs to read 4 books
For the second one, it should be
(50-(7*5)/5)*7 or (50-35/5)*7= 5*7=35
Sorry if I'm wrong!
Answer:
sin(y)=15/17
cos(y)=8/17
tan(y)=15/8
Step-by-step explanation:
We know that sinФ=Opposite/Hypotenuse, cosФ=Adjacent/Hypotenuse, and tanФ=Opposite/Adjacent. We can remember this with the phrase SOH-CAH-TOA.
We know our angle is Y. The opposite side of Y is 15. The adjacent side of Y is 8. The hypothenuse is 17.
Now, we can plug the given information into the formulas and get the solutions.
sin(y)=15/17
cos(y)=8/17
tan(y)=15/8

Answer:
Population after 4 years = 49 (nearest unit)
Population after 5 years = 47 (nearest unit)
Step-by-step explanation:
Yearly decrease = 4.6%
Decrease factor (what's left) = (100-4.6)% = 0.954
Current population, P = 60
population after n years = P(0.954)^n (to the nearest unit)
Population after 4 years = 60(0.954)^4 = 49.7 = 49 (nearest unit)
Population after 5 years = 60(0.954)^5 = 47.4 = 47 (nearest unit)
