The total number of marbles in the bag is 7, since 3+4=7. There are 3:4 black marbles, so 3/7 of the bag is black marbles, which can be written as 3:7.
4/7 of the bag is red marbles, which can be written as 4:7
Answer:
Option B
Step-by-step explanation:
First identify which options are a match for the hyperbola with a foci of (- 12, 6) and ( 6, 6 ). If there is only one, we can claim that that is the solution. Otherwise we would have to take the vertices into account,
The first option can be eliminated as it is present with a decimal in the denominator, indicating that the foci should also be a decimal. However, the foci of this option should be valuable to us -

The second option squares the denominators of the first option, so the foci should be the following -

Which is the given! The rest of the options are similar to this second option, but are altered, thus don't have the same foci,
<u><em>Solution = Option B</em></u>
Answer:
X. 120 Y. 30 Z. 36.5
Step-by-step explanation:
X. 360-107-133= 120
Y. Length of AB is equal to 120, so angles y and C are equal to 60. 60/2= 30
Z. 133+ 30= 163. 180-163= 17. Angle A and Z equal to 53.5. 53.5-17= 36.5
The correct answer is that she picked 16 green peppers. We can work this
out because 16 + 4 = 20, and 4 x 4 is 16, so therefore there were 16
green peppers and 4 red peppers.
