Question

50 POINTS IF YOU ANSWER THIS, IF CORRECT I WILL GIVE BRAINIEST!!!!!

Answer 1

Answer:

B, C, E

Step-by-step explanation:

B) $\frac{3a+3b}{3a-3b}$ = $\frac{3(a+b)}{3(a-b)}$=$\frac{a+b}{a-b}$

c) $\frac{2(a+b)}{4(0.5a-0.5b)}$=$\frac{2a+2b}{2a-2b}$=$\frac{2(a+b)}{2(a-b)}$=$\frac{a+b}{a-b}$

E) $\frac{1/3a+1/3b}{0.3a-0.3b}$=$\frac{0.3a+0.3b}{0.3a-0.3b}$=$\frac{0.3(a+b)}{0.3(a-b)}$=$\frac{a+b}{a-b}$

The others are not the same ratio:

Answer 2

Answer:666

Step-by-step explanation:

Because the ball is softer than the floor, it does most of the denting and stores most of the energy. ... When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
