Answer:
36 squared units
Step-by-step explanation:
So you can draw "made up lines" or I guess lines you draw yourself to create 2 rectangles. Check attachment.
The first rectangle is a square and has sides 3 and 3, so you get the area of 9.
The second, has sides 9 and 3, so you get the area of 27
Since you are trying to find the entire thing, you add 27 and 9 to get 36
A bag contains 15 blue marbles, 5 red marbles, and 11 green marbles. How many blue marbles must be removed
from the 31 marbles in the bag so that the probability of randomly drawing a blue marble is 1/3?
Answer:
7 blue marbles
Step-by-step explanation:
15 blue
5 red
11 green
Total = 31
Number of Blue marbles that must be removed to obtain a probability of :
P(blue) = 1/3
Probability = required outcome / Total possible outcomes
Let number of blue marble to be removed = x
Number of Blue becomes : 15 - x
Total becomes : 31 - x
P(blue) = 1/3
1/3 = (15 - x) / (31 - x)
1/3 * (31 - x) = 15 - x
(31 - x) / 3 = 15 - x
31 - x = 45 - 3x
-x + 3x = 45 - 31
2x = 14
x = 14 / 2
x = 7
Answer:
A, C, and D
Step-by-step explanation:
Remember that in a function, every unique input must have one output. Therefore, two or more outputs cannot have the same input. Knowing this, we can eliminate choice B. Therefore, A, C, and D are correct.

Answer:
<u>A) 2¹²</u>
Step-by-step explanation:
Given :
Equate the equation to y :
- 3x - y + y = 12 + y
- 12 + y = 3x
- 12 + y - 12 = 3x - 12
- <u>y = 3x - 12</u>
