Answer:
The number of faces is 29
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
In this problem we have
Substitute in the formula and solve for F
Let
the amount of money invested at 9% and
the amount of money invested at 5%. The amount invested at 5% (
) is 1700$ less than the amount invested at 9% (
) it means:
(equation 1)
The investments produced 223$ which means:
. (equation 2)
We use the first equation to eliminate
from equation 2:
He invested 2200$ at 9% and 500$ at 5%.
Answer: 1/56
Step-by-step explanation:
Since the box has 8 different colors, the probability of picking any color of crayon will be 1/8.
This question relates to a probability without replacement, therefore, the probability of picking the red crayon first will be 1/8. After then, there'll be 7 crayons left and the probability of picking the green crayon next will be 1/7.
Therefore, the probability that I will remove the Red and the Green crayon from the box will be:
= 1/8 × 1/7
= 1/56
