Answer:
C. Each side in the pre-image is multiplied by three to find the corresponding side length in the image.
Step-by-step explanation:
The scale factor multiplies every linear dimension in the pre-image. It is the ratio of image dimensions to pre-image dimensions.
So, for a scale factor of 3, each side in the pre-image is multiplied by 3.
Answer:
The answer is 40
Step-by-step explanation:
The reason it’s fourth is because your multiplying and subtracting
Answer:
Amy traveled at 4.5 mph, while Jim traveled at 6 mph. Therefore, Jim traveled at a greater average speed.
Step-by-step explanation:
Given that Amy drove her hoverboard 3 miles in 40 minutes, while Jim hopped 2 miles in 20 minutes, to determine who traveled at a greater average speed, the following calculation must be performed:
(3/40) x 60 = Amy's speed
0.075 x 60 = Amy's speed
4.5 = Amy's speed
So Amy traveled 4.5 miles per hour.
(2/20) x 60 = Jim's speed
0.1 x 60 = Jim's velocity
6 = Jim's speed
Instead, Jim traveled 6 miles per hour.
Therefore, Jim was the one who traveled at a greater average speed.
To begin with the vertical line is y and the horizontal line is x. There are two coordinates per piece of the graph. (X,Y) The first one right down the middle is (0,1) graph the first number being x and the second being y. hope this helps a bit
