<h3>
Answer: D) 1/3</h3>
================================================================
Explanation:
Start at (2,-3). Move up 3 and over to the right 6 spots to move to (8,0) which is where point F is located.
We can write the slope as rise/run = 3/6
Go back to (2,-3). Move up 1 and to the right 2 spots to arrive at F ' (4,-2)
Let's now compare the upward movements:
- Initially we moved up 3 units when trying to get to point F
- Now we're only moving up 1 unit when getting to F'
The starting point each time is (2,-3) which is the center of dilation. The jump from 3 to 1 is "times 1/3" and that's our scale factor. Every linear distance in the image is 1/3 times as long compared to the preimage.
We can also get the same scale factor when comparing the horizontal movements as well. The jump from 6 to 2 is also "times 1/3".
Answer:
32 percent the puppy's weighed increased.
Step-by-step explanation:
In February Lana got a puppy that weighed 13 kilograms.By October the puppy weighed 17.16 kilograms.
Original weighed = 13 kilogram
Final weighed = 17.16 kilogram.
Increase in weighed = 17.16-13 = 4.16 kilogram.
Now to find the percent the puppy's weighed increased.
Percent = ![\frac{increase weighed}{original weighed} \times 100](https://tex.z-dn.net/?f=%5Cfrac%7Bincrease%20weighed%7D%7Boriginal%20weighed%7D%20%5Ctimes%20100)
Percent = ![\frac{4.16}{13} \times 100 = 32 \%](https://tex.z-dn.net/?f=%5Cfrac%7B4.16%7D%7B13%7D%20%5Ctimes%20100%20%3D%2032%20%5C%25)
Hence, the percent the puppy's weighed increased was 32%.
Answer:
D.) Collecting the cholesterol readings of a group of people in a certain age group in a small town
Step-by-step explanation:
Let's denote width1 with a and length1 with b. Then, the area of this room is
![A_{1} = a*b](https://tex.z-dn.net/?f=A_%7B1%7D%20%3D%20a%2Ab%20)
Let's denote width2 with c and length2 with d. Then, the area of the second room is
![A_{2} = c*d](https://tex.z-dn.net/?f=A_%7B2%7D%20%3D%20c%2Ad%20)
The total area of the rooms is
