Answer:
2 hours
Step-by-step explanation:
Circumference = pi × d
126 = 3.14 × d
d = 40.127388535 yards
d = 40 yards (nearest whole number)
Time = 40/20 = 2 hours
Answer:
- 4. -3
- 5. -1/2
- 6. 1/2
- 7. 4
- 8. 0
- 9. undefined
Step-by-step explanation:
<u>Use of slope formula:</u>
4.
- m = (7 - 4)/(1 - 2) = 3/-1 = -3
5.
- m = (-2 - 0)/(3 - (-1)) = -2/4 = -1/2
6.
- m = (5 - 3)/(5 - 1) = 2/4 = 1/2
7.
- m = (3 - 0)/(3.5 - 4.25) = 3/0.75 = 4
8.
- m = (3/4 - 3/4)/(5 - 2) = 0
9.
- m = (2 - 3)/(7.5 - 7.5) = -1/0 = undefined
Answer:
Uh if you added a picture I cant see it
7x=y, because you first multiply y by 7 so you then have to do the same to x, so that gives you 7x=y
