42/60, x/320. 320/60=5.33333, 42*5.33333=224. So, about 224 students would ride the bus.
9.2x10^-8
Move the decimal to the right 8 times. Since it is moved to the right, the exponent is negative.
It would be none because the same would be the reciprocal which would be (-7, -8.75)
Answer:
Option B

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem the only linear function that passes through the origin is

where
The constant of proportionality is k=3/4
