We let x be the multiple of each side of the triangle. Then, we add all sides to obtain the perimeter.

1x + 2x + 2x = 15
5x = 15
x = 15/5
x = 3

The multiple is 3. We multiply this to the ratio to get the actual lengths of the sides. That would be 3, 6 and 6. Thus, the shortest side is 3 feet.

A fair spinner has 10 equal sections: 3 red, 3 blue and 4 green. It is spun twice. What is the probability of getting not green
Nonamiya [84]

Answer:

0.24

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome. The probability that an even will happen or not happen is 1.

Given that the spun has 10 sections 3 red, 3 blue and 4 green, the probability of not getting green

= (3 + 3)/(3 + 3 + 4)

= 6/10

The probability of getting green

= 4/10

Hence the probability of getting not green then green

= 6/10 * 4/10

= 24/100

= 0.24
