There are eight hamsters at crazy peds pet shop that are completely brown. The rest of the hamsters at the shop or mixed colors.

Alina [70]

There are a total of 20 hamsters. I solved it by dividing the 8 hamster by 2 to get what 1/5 would be. After i know 1/5=4 hamsters i multiplied 4*5

4 hamsters is the same as 1/4 of all the hamster

8 hamsters=2/5

12 hamster=3/5

16 hamster=4/5

Please select the best answer from the choices provided

Answer:

The correct answer is option B. 8,16, 20

Step-by-step explanation:

Its given that,ΔJKL ~ ΔPQR, with a scale factor of 3 : 4

The sides of ΔJKL are, 6,12,15

Let 'x', 'y', and 'z' be the sides of ΔPQR

We know that if two triangles are similar, then the ratio of corresponding sides are in same raio.

To find x

6/x = 3/4

x = 8

To find y

12/y = 3/4

y = 16

To find z

15/z = 3/4

z = 20

Therefore the sides of ΔPQR are 8,16 and 20

Option B. 8,16,20 is the correct answer

Geometry help please! Thanks!

masya89 [10]

Mid point formula

(x1 + x2) , (y1+y2)
--------- --------
2 2
Thus for x it would be (6+(-2)) /2 or 4/2 or 2.
For y (-4 + 4) / 2 or 0 / 2 or 0.
Mid point is (2,0)
