Express each ratio as a unit rate. round to the nearest tenth, if necessary. 400 feet in 52.4 seconds

7.6 ft/sec

Step-by-step explanation:

Given : 400 feet in 52.4 seconds

To Find : Express each ratio as a unit rate.

Solution:

Distance = 400 feet

Time = 52.4 seconds

So, 400 feet in 52.4 seconds

So, in 1 second =

                        =

So, unit rate =7.6 ft/sec

Hence 400 feet in 52.4 seconds as unit rate is 7.6 ft/sec

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
