There are 7 times as many females as males on the maths course at university. What fraction
of the course are female?
Give your answer in its simplest form.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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)

is there any other information given for this problem? this is not enough information.
