Answer:

Step-by-step explanation:

$\dfrac{x}{5}+1=7\qquad\text{subtract 1 from both sides}\\\\\dfrac{x}{5}+1-1=7-1\\\\\dfrac{x}{5}=6\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{x}{5\!\!\!\!\diagup_1}=5\cdot6\\\\x=30$

Suppose that you are provided with the following data for your country for a particular month: 200 million people are working, 2

lisov135 [29]

Answer:

$Unemployement\,\,rate=23%$

Step-by-step explanation:

To find the unemployment rate we have the next expression:

$Unemplyment\,\,rate=\frac{Unemployment\,\,people}{Total\,\, labor\,\, force}\cdot 100$

We have the next data:

200 million employed

20 million unemployed

40 million umemployed are not looking for a job

Then the total labor force will be the employed and the unemployed population then de have 260 million

$Unemployement\,\,rate=\frac{60million}{260million}\cdot 100$

$Unemployement\,\,rate=\frac{6}{26}\cdot 100$

$Unemployement\,\,rate=0.23\cdot 100$

$Unemployement\,\,rate=23%$

George plans to cover his circular pool for the upcoming winter season. The pool has a diameter of 20 feet and the cover extends

MariettaO [177]

For the circular cover we have:

A) The area is 379.94 ft²

B) The length of the rope must be 68.2 ft

<h3>How to get the area of the cover?</h3>

Remember that the area of a circle of radius R is given by the formula:

$A = pi*R^2$

Where pi = 3.14

In this case, the diameter of the pool is 20ft, then the radius is:

R = 20ft/2 = 10ft

And it must extend 12 inches beyond, then the radius of the cover must be:

R = 10ft + 12in

Now, we know that 1ft = 12 in, then we can rewrite the radius as:

R = 10ft +1ft = 11ft

Then the area of the cover is:

$A = 3.14*(11ft)^2 = 379.94 ft^2$

B) now we want to get the length of the rope, we know that the rope runs along the cover, then the length of the rope must be equal to the circumference of the cover.

Remember that the circumference of a circle of radius R is:

$C = 2*pi*R$
