Answer:
1/15
Step-by-step explanation:
5+3+2 = 10
Chance of pulling out a yellow marble = 3/10
Once you pull out the marble there are 9 marbles left, 2 yellows, 2 blacks and 5 whites.
Chance of then pulling out a black marble = 2/9
3/10 x 2/9 = 6/90
6/90 = 1/15
Supplementary angles add up to 180°.
89°= angle 1
x= angle 2
Add the two angles equal to 180°
x + 89= 180
subtract 89 from both sides
x= 91°
ANSWER: The measure of the supplementary angle is 91°.

Answer:
Table B
Step-by-step explanation:
Note that for y to vary inversely as x, an increase in x will cause a decrease in y. Therefore, by careful observation of tables A, B, C, and D, we would notice the following:
In table C:
As x increases from 1 to 2 to 3, y also increases from 26 to 52 to 78. Which means that an increase in x causes an increase in y. This is not an inverse variation.
In table D:
As x increases from 1 to 2 to 3, y also increases from -7 to -1 to 6. Which means that an increase in x causes an increase in y. This is also not an inverse variation.
We are left with options A and B
If y varies inversely as x, the following relationship must hold:
Where k is a constant of proportionality
considering option B:
When x = 1, y = 36
36 = k/1
k = 36 * 1
k = 36
when x = 2, y = 36/2
y = 18
when x = 3, y = 36/3
y = 12
These tally with all that is indicated in the table. Option B is an inverse variation
