Answer:
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is ⇒ B
Step-by-step explanation:
In similar rectangles, their corresponding dimensions are proportional, which means =
, where L is the length and W is the width
∵ Rectangle ABCD is similar to rectangle MNOP
∴ Their dimensions are proportional
∵ The dimensions of rectangle ABCD are 6 m, 14 m
∴ L = 14 and W
= 6
∵ The dimensions of rectangle MNOP are 4.5 m, 10.5 m
∴ L = 10.5 and W
= 4.5
∵ The rectangle MNOP is the image of rectangle ABCD after dilation
→ To find the scale factor of dilation find the ratio between the
corresponding dimensions in the two rectangles (image/pre-image)
∵ =
=
∵ =
=
∴ The scale factor for the dilation is
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is
Answer:
Therefore,
Jana bikes 18 miles in one hour.
Step-by-step explanation:
Given:
Jana bikes,
15 miles ---------------> in 50 minutes
To Find:
How many miles ------------------> in 1 hour = 60 minutes
Solution:
Let 'x' miles Jana Bikes in 1 hour or 60 minutes
As, 1 hour = 60 minutes
The Ratio of Equation will be
Cross Multiplying we get
Therefore,
Jana bikes 18 miles in one hour.
