Answer:

12

Step-by-step explanation:

I am represent 1/4 as a quarter of a circle, and 3 as 3 full circles.

How many quarters of a circle are there in 3 full circles.

There is 4 quarters of a circle in one full circle. Multiplying that by 3, there are 12 quarters of a circle in 3 full circles. So there are 12 quarters in 3.

A puppy and kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 meters per second, while th
Gnom [1K]

It seems it should be the other way... . How soon will the puppy catch up with the kitten.

The way you have it the kitten will never catch the pup. There is already 180m between them so, the distance will only increase because the puppy runs faster than the cat.

If the puppy runs after the cat, will eventually catch up with it and can be calculated. Not the other way around.

If the pup runs after the cat, the distance between them will decrease and the pup will catch the cat.

RT = D kitten

RT = D+180 puppy

20T = D

25T = D + 180

Substitution

25T = 20T +180

5T = 180

T = 36s

Multiplication -> Division
Squaring -> Square rooting

Cubing -> Taking the cube root

Addition -> Subtraction

Alternative:

Basically, an inverse is a mathematical manipulation where one operation undoes the action of the other.
