Answer:
1/9
Step-by-step explanation:
the probability of one blue marble is 1/3 so to find the probability of 2 marbles you multiply it by itself.
Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.
<h3>What are Supplementary Angles?</h3>
The sum of angles that are supplementary to each other equals 180 degrees.
Let the measure of the supplementary angle be x.
The other angle will be: x + 20.
(x + 20) + x = 180
x + 20 + x = 180
2x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80°
The other angle will be x + 20 = 80 + 20 = 100°.
The measure of the angles are: 80° and 100°.

Step-by-step explanation:
Answer:
d is parallel to e
Step-by-step explanation:
Since b is parallel to e and d is perpendicular to b , then
d is perpendicular to e
Answer:
(a)10 modules per floor
(b)Two different rectangular prism
Step-by-step explanation:
<u>Part A</u>
Number of modules=130
Number of stories=13
Since all of the modules were divided evenly among the number of stories:
Number of module per floor =130÷13=10 modules per floor
There would be 10 modules on each floor.
<u>Part B</u>
Next, we determine how many different rectangular prisms could be made from the number 10 derived above.
Step 1: List the factors of 10
Factors of 10 are: 1,2,5 and 10
Step 2:
Form a product of three terms which equals 10 using the factors derived above. We have two possible combinations:
Therefore, two different rectangular prisms could be made from the number of modules on each floor.
