For shape A, it’s simply length x height.
So, that would be 9.2cm x 11.3cm= 103.96

For shape B, it’s base x height = area.
So, that would be 8 1/2cm x 11cm = 93 1/2

For shape C, you have to multiply the height and by the base and then divide by 2:
8cm x 14.5cm = 116 divided by 2= 58

For shape D, it’s 112cm.
You add the two bases together and then multiply by height. Then divide by 2.

Then simply put all the numbers from greatest to least.

A bag contains 3 red, 2 blue, 5 yellow, and 2 green marbles. What is the probability of choosing a red marble and then a blue marble

A. 5/23
B. 1/22
C. 5/21
D. 1/24

Answers

Multiply 3/12 * 2/12 = 6/144

Simplify to get 1/24 by dividing too and bottom by 6.

Answer:

12 outcomes

Step-by-step explanation:

To get a red on the counter, it's a 50% chance. To get a number greater than 3 on a spinner with numbers labeled 1 to 6, it's another 50% chance. To get the chance of both happening, you'll have to multiply both percents together. 50% x 50% = 25%

2/5 = 0.4 = 40%

40% of 80 is 32

25% of 80 is 20

32 - 20 is 12
