Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west. How far apart are the sales representatives? Estimate the distance to the nearest tenth. 22.6 mi 16.4 mi 20.6 mi 11.8 mi

d = 20.6 miles

Step-by-step explanation:

Given that,

Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west.

It is required to find the distance between two representatives. It it is d. It can be calculated as the resultant if two values as follows :

So, the sales representative are 20.6 miles apart. Hence, the correct option is (c).

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
