gradient of AB:

gradient=-4-1/2-3

=-5/-1

gradient of BC:

=-5+4/7-2

=-1/5

b) as the priduct of both gradient is -1 ,both lines are perpendicular.

c) as we have seen lines are perpendicular so it is a right angled triangle.

Question:

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. what is the unit rate at which Martian paints in walls per gallon

Answer:

0.78125 walls per gallon

Step-by-step explanation:

Given

$Paint = \frac{5}{8}\ gallon$

$Wall = \frac{4}{5}$

Required

Determine the unit rate

This is calculated as:

$Unit\ Rate = \frac{Wall}{Paint}$

Substitute values for wall and paint

$Unit\ Rate = \frac{5/8}{4/5}$

Simplify:

$Unit\ Rate = \frac{5}{8}/\frac{4}{5}$

Change to *

$Unit\ Rate = \frac{5}{8}*\frac{5}{4}$

$Unit\ Rate = \frac{5*5}{8*4}$

$Unit\ Rate = \frac{25}{32}$

$Unit\ Rate = 0.78125$

<em>Hence, the unit rate is: 0.78125 walls per gallon</em>
