In the picture, rectangle R is divided into some smaller rectangles as shown. Is R a scaled copy of C? If so, what is the scale factor?

Scale factor = 36

Step-by-step explanation:

R is a biggest rectangle and C is the smallest rectangle in the picture

attached.

Rectangle R = 4 × [Rectangle B]

                    = 4 × [9 × rectangle C] {since rectangle B is formed by joining 9 rectangles of C}

                    = 36 × rectangle C

This shows that R is a scaled copy of C.

Since, scale factor = [Scale factor for rectangle R from C]

                               =

                               = 36

Therefore, scale factor by which C is enlarged to form R is 36.

366

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
