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

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

Someone Help? Im confuzzled

cupoosta [38]

Answer: 16π

Step-by-step explanation:

First, solve for total area:

A = πr^2

A = π(8^2) = 64π

Then, find 1/4 of the area of the whole (since this is only a quarter circle)

A/4 = (64π)/4 = 16π

Math problem!!! Help needed 10 points !!!

My name is Ann [436]

ANSWER

Option D

EXPLANATION

The parent radical function is

$f(x) = \sqrt{x}$

The transformed function is

$g(x) = 2 \sqrt{x - 3}$

This is a transformation of the form.

$y = a \sqrt{x - k}$

which shifts the parent function horizontally by k units to the right and stretches the parent function vertically by a factor of 'a'.

In this case a=2 and k=3,

there is a horizontal shift of 3 units to the right and a vertical stretch by a factor of 2.

The last choice is correct.

Kyle makes 2,500 a month plus 20% of his sales. If he wants to earn no less than $4000 this month, write and solve an inequality

Nina [5.8K]

Answer:

kyle must sell 7500$

Step-by-step explanation:

If you take the 2500$ he makes base salary and subtract from 4000$ you get 1500$ and if you multiply it by 1.80 you get the other needed 80% of the required sales.
