Answer:

B. 80 cm

Step-by-step explanation:

A scale factor of 4 multiplies each side length by 4, so the perimeter also becomes 4 times larger.

4 * 20 cm = 80 cm

Answer: 80 cm

Olive flipped a coin and rolled a number cube with the numbers 1-6 on it.What is the probability that she flipped heads and roll
Helen [10]
The probability that Olive flips heads and rolls an even number is 3/12 or 1/4.

These events are known as independent events which means the result of one event will not affect the other. The find the probability of the two events, you must multiply the probability of flipping heads and rolling an even number on a number cube.

1/2 x 3/6 = 3/12 OR 1/4 :)

The ratio of star beads to moon beads in a bracelet is 9:6.
Arlecino [84]
So for every 9 star beads you have, you have 6 moon beads. The rule is dividing.
6 divided by two (because we have two moon beads) is 3.
9 divided by three (because that's the answer to the first part) is 3.
So there are 3 star beads.
