A sled sells for $40 is on sale for $28. By what percent is the price reduced?

40-28-12    

12/40 = 0.3

0.3 = 30%

Step-by-step explanation:

The price is reduced by 30 percent

Step-by-step explanation:

the price was reduced by 30 percent how I got the answer was taking by taking 100 dividing it by 40 then multiplying it by the new number 28, with this it gives you 70 and that means it is 70 percent of the whole answer 40 so that's how you get 30 percent as the reduction.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

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)
