Answer:
Equation: y=.50x+5.00
Answer 1: You would have to pay 15.00 dollars total.
Answer 2: 40 miles
Step-by-step explanation:
Answer 1:
The flat fee is 5.00 dollars. plus it's 00.50 cents per mile. So, what's the half of 20? It's 10. So, 10.00 dollars plus 5.00 is $15.00 .
Answer 2:
Okay, so here, you have $25.00. So, you can go ahead and take the 5.00 away cause that's the flat fee. So, we know that you need $10.00 for 20 miles, so if we have $20.00, then that would take you 40 miles.
Using the Law of Sines (sina/A=sinb/B=sincC for any triangle)
sinc/28=sin90/53 (sin90=1) multiply both sides by 28
sinc=28/53 take the inverse of sin (arcsin) of both sides
c=arcsin(28/53)°
c≈31.89° (to nearest hundredth of a degree)
So it is obvious that they rounded to nearest tenth of a degree
c≈31.9°
-0.2
'0
-0.2 = - .2 = - 2/10 = - 1/5
so
answer is -1/5
I believe it is 30 cubic yards. There are 27 cubic feet per cubic yard. Correct me if I'm wrong!
