1. A man wants to place cobblestone on his driveway. It is a perfect rectangle that has measurements of 45 feet by 60 feet. One box of cobblestone will cover 35 square yards. If you cannot buy a partial box, how many boxes of
cobblestone will he need to purchase to cover the driveway?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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)

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
