What is 170% of 520? Round to the nearest hundredth (if necessary).

884

Explanation: Set up your equation as you read through the problem.

Also, remember that percent means over 100.

What means x, is means equals, 170% means

170/100, of means times, and 60 means 60.

Simplifying on the right side of the equation,

we can reduce 170/100 to 17/10.

So we have x = 17/10 · 520.

Put 520 over 1 then cross-cancel 520 and 10 to 52 and 1.

So our answer is 17 · 52 or 884

step-by-step explanation:

8+8+6+6

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)
