Robin is making bows to sell at her mother's yard sale. She will use 3/4foot of red ribbon and 2/3foot of blue ribbon to make each bow. What is the ratio of the length of red ribbon to blue ribbon?

Solution:

Given that,

Robin is making bows to sell at her mother's yard sale

From given,

What is the ratio of the length of red ribbon to blue ribbon?

Thus ratio of length of red ribbon to blue ribbon is 9 : 8

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
