Answer:
Roni did not make use of the equation for a proportional relationship.
Step-by-step explanation:
For some constant of proportionality k, y is proportional to x if x and y satisfy the equation ...
y = kx
Roni knows k=7/25, but she did not use this equation. She added instead of multiplying, so did not end with an equation expressing a proportional relation.
___
y = (7/25)x
Answer:
5×2y=2:z (5-,-6 and is perpendicular to the line .
Step-by-step explanation:
5×2y=2:
The large tire makes 3 rotations, and the small tire makes 11 rotations.
We must find the circumference of each tire to know how many feet are covered when it makes one complete rotation.
C=πd
For the large tire, this means:
C=3.14(60) = 188.4
Dividing 600/188.4, we get (to the nearest whole number) 3 rotations.
For the small tire, we have:
C= 3.14(2*9) = 3.14(18) = 56.52
Dividing 600/56.52, we get (to the nearest whole number) 11 rotations.
Answer:
C:16
