A = ab ( the area of rectangle )
a b = 192
a b r² = 363
192 r² = 363
r = √363 / 192 = √121/64
r = 11/8
The similarity ratio of the two rectangles is 11/8.
If we divide 55 (the total amount of money he made) by 5 (price to walk one small dog), we get 11. Meaning that the maximum amount of small dogs he could possibly walk and receive that amount of money is 11. However, he only walked 8 dogs. Therefore Ryan would have needed to walk a specific amount of large dogs in order to earn 55 dollars in total.
After doing some process of elimination, I reached this conclusion:
3 small dogs = $15
5 large dogs = $40
The combination of the two would equal $55.
Therefore, the answer would be 3 small dogs.
This is the transitive property :)
(5,-3) (-1,6)
y=mx+b
calculate m:
(-3-6)/(5-(-1)
=-9/6=-1.5
y=-1.5x+b
insert the (5, -3) point to calculate b:
-3=-1.5*5+b
-3=-7.5+b
4.5=b
b=the y intercept, so the line intercepts x=0 at y=4.5
Your proportion should look something like this

After cross multiplication, you should end up with this equation

After dividing 4 on both sides, you should get that x=9
