Answer:
RO = 39.5
Step-by-step explanation:
RO/9 = 57/13
13RO = 513
RO = 513/13
RO = 39.46
Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'
<span>A y = $6.5x, y = $52.00</span>
She will need 5 and a half hours. First step is to do 360-112.5 the pgs she read and her goal. then you'll get 247.5. To find how many hours you need to find the unit rate. so 247.5 divided by 45 is 5.5 hours.
hope this helped. can u mark me as the brainiest answer

Answer:
59
29.33
Step-by-step explanation:
Recall SOH CAH TOA
SOH= Sinα=opposite/hypotonouse
CAH= cosα=adjacent/hypotonouse
TOA= tanα=opposite/adjacent
To find angle C we'll use TOA
which means we take the lenght opposite to d and adjacent to d
which means we have
tand=10/6
d=tan⁻1(10/6)
d=59
to find length z let's use SOH CAH TOA again (for the practice)
This time let's use angle z and SOH
which means we have
sin(64.5)=z/32.5
Solve for z
32.5sin(64.5)=z
z=29.33
*note* if you use a²+b² for number two you get a sligthly different answer. This is because when they rounded when they wrote 64.5**
