What is the fraction and the percent of the shaded part in each square?

elena-14-01-66 [18.8K]

Answer:

Part a) The fraction is $\frac{5}{9}$

Part b) The percent is $55\frac{5}{9}\%$

Step-by-step explanation:

Part a)

Find the fraction

we know that

To find the fraction of the shaded part in the square divide the number of shaded squares by the total number of squares

Let

x-------> the number of shaded squares

y-------> the total number of squares

f-------> the fraction of the shaded part

$f=\frac{x}{y}$

In this problem we have

$x=20\ shaded\ squares$

$y=36\ total\ squares$

substitutes

$f=\frac{20}{36}$

Simplify

$\frac{20}{36}=\frac{5}{9}$

Part b) Find the percent

To find the percent multiply the fraction by 100

$\frac{5}{9}*100=\frac{500}{9}\%$

convert to mixed number

$\frac{500}{9}=\frac{495}{9}+\frac{5}{9}=55\frac{5}{9}\%$

Before the election, you want to determine the number of possible president/vice-president combinations for the sorority you bel

vichka [17]

Solution: We have to choose two positions president and vice president from eight people. So, we need to use the Permutations formula in order to find the possible number of combinations.

The number of possible combinations is:

8P2 $=\frac{8!}{(8-2)!}$

$=\frac{8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1}$

$=\frac{40320}{720}$

$=56$

Therefore the possible number of combination to select two positions from 8 people is 56
