The circumferences of two circles are in the ratio of 2: 5. the radius of the smaller circle is 16 in. what is the radius of the larger circle? 32 in. 40 in 80 in 160 in.

Here, x represents the number of minutes and y represents the number of laps.

(a)

Given two points: (4.5, 3.5 ) and (7.5, 5.75)

To find the slope of a line.

Using slope(m) formula for two points:

then, substitute the given values we have;

Therefore, slope of a line is, 0.75

(b)

Kailee run per minute = 0.75 laps

(c)

Now, find the number of laps would she run in 24 min.

in 1 min, she run 0.75 laps

then

in 24 minute , she run laps

therefore, 18 laps would she run in 24 laps.
