The perimeter of a rectangle is 1000m. if the length is given as x , find the width in terms of x

1 answer:

4 0

$\text{Given that,}\\\\\text{Perimeter = 1000 m}\\\\\implies 2(\text{Length} + \text{Width}) = 1000~ \text m\\\\\implies (x+ \text{Width}) = \dfrac{1000}2 =500~ \text m\\\\\implies \text{Width} =(500 -x) ~\text{m}$

Joseph earns $15 for every lawn he mows. Is the amount of money he earns proportional to the number of lawns he mows? Make a tab

Vedmedyk [2.9K]

Given that Joseph earns $15 for every lawn he mows.

so if he mows lown 1 time then his earning = $15

if he mows lown 2 time then his earning = $15*2= $30

if he mows lown 3 time then his earning = $15*3= $45

if he mows lown 4 time then his earning = $15*4= $60

if he mows lown 5 time then his earning = $15*5= $75

So the required table will be:

From the table we can see that Joseph's earning increases by $15 each time so we can say that YES, the amount of money he earns proportional to the number of lawns he mows.
