The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure. Scale factor: 5:8

Surface area: 475

volume: 1125

Surface area: ?

volume: ?

Surface area: 1216

Volume: 4608

Step-by-step explanation:

Scale factor: 5:8

This means that the dimensions of the larger figure are 8/5 of those in the smaller figure.

Surface area:

The surface area is found multiplying the square of the change(8/5) by the original surface area(475). So

Volume:

The volume is found multiplying the cube of the change(8/5) by the original volume(1125). So

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)
