Answer:

A. 120%

B. 150%

Step-by-step explanation:

a. Let 'a' represent the percentage of interest.

600 = a% × 500

600/500 = a/100 . . . . . . . % means /100

100(6/5) = a = 120

600 is <u> 120 </u>% of 500

b. Let 'b' represent the percentage of interest. The given statement means ...

100 = 40 + b% × 40

100 = 40(1 +b/100) . . . . . factor out 40, use /100 for %

2.50 = 1 +b/100 . . . . . . . divide by 40

1.50 = b/100 . . . . . . . . . . subtract 1

150 = b . . . . . . . . . . . . . . multiply by 100

100 is <u> 150 </u>% more than 40

Which graph represents the solution to the given system? y=5x+4; y=5x-3

Mars2501 [29]

Hello from MrBillDoesMath!

Answer:

The lines do not intersect

Discussion:

Where do the lines intersect?

5x + 4 = 5x - 3 => subtract 5x from both sides

4 = -3 => NO WAY! The lines do not intersect

Thank you,

The sector COB is cut from the circle with center O. The ratio of the area of the sector removed from the whole circle to the ar

mafiozo [28]

Answer:

$Ratio = \frac{R^2 - r^2 }{ r^2}$

Step-by-step explanation:

Given

See attachment for circles

Required

Ratio of the outer sector to inner sector

The area of a sector is:

$Area = \frac{\theta}{360}\pi r^2$

For the inner circle

$r \to radius$

The sector of the inner circle has the following area

$A_1 = \frac{\theta}{360}\pi r^2$

For the whole circle

$R \to Radius$

The sector of the outer sector has the following area

$A_2 = \frac{\theta}{360}\pi (R^2 - r^2)$

So, the ratio of the outer sector to the inner sector is:

$Ratio = A_2 : A_1$

$Ratio = \frac{\theta}{360}\pi (R^2 - r^2) : \frac{\theta}{360}\pi r^2$

Cancel out common factor

$Ratio = R^2 - r^2 : r^2$

Express as fraction

$Ratio = \frac{R^2 - r^2 }{ r^2}$

If a company has five employees with annual salaries of $60,000, $70,000, $60,000, $90,000, and $80,000, respectively, what is t

Vanyuwa [196]

well to find the mean you add up all the numbers then divide by the ammount of numbers so it would be 60,000+70,000+60,000+90,000+80,000=360,000 then you divide that by 5 and you end up with 72,000
