Many us employess received a 3% raise in 2012 suppose an employee made 47,000 in 2011 and received a 3% raise. What did she make

WITCHER [35]

First lets get 3% into decimal form.

3% is 3/100 = 0.03

Now multiply 0.03 by 47000 to get how much extra money she was going to get.

47000 * 0.03 = 1410

Now we just add
47000 + 1410 = 48410 is what she was going to make in 2012

Another way to do this is

(47000)(1+0.03) = 48410

you would use (1+0.03) which tells you she increased in pay.

Please help with this<br><br> Find the area of the shaded regions.

Mice21 [21]

Answer:

The area of the shaded region is 7π square centimeters.

Step-by-step explanation:

Note that Circle B has a radius of 3 cm, and the two smaller circles, Circles O and C, both have a radius of 1 cm.

The area of a circle is given by:

$\displaystyle A = \pi r^2$

Therefore, the area of Circle B, the entire circle, is:

$\displaystyle \begin{aligned} A_B &= \pi (3)^2 \\ &= 9\pi \end{aligned}$

The area of Circle O is:

$\displaystyle \begin{aligned} A_O &= \pi (1)^2 \\ &= \pi \end{aligned}$

And likewise, the area of Circle C is:

$\displaystyle \begin{aligned} A_C &= \pi (1)^2 \\ &= \pi \end{aligned}$

The area of the shaded area is the area of the Circle B subtracted by the area of Circles O and C. Hence:

$\displaystyle A_\text{shaded} =A_B - \left(A_ O + A_ C\right)$

Substitute and evaluate:

$\displaystyle \begin{aligned} A_\text{shaded} &= (9\pi ) - (\pi + \pi) \\ &= 9\pi - 2\pi \\\ &= 7\pi \end{aligned}$

The area of the shaded region is 7π square centimeters.

Vince needed five eights of a package of marbles for each gift bag if he had to make five gift bags how many packages of marbles

Alenkasestr [34]

Answer:

$3\frac{1}{8}$ packages of marbles.

Step-by-step explanation:

We have been given that Vince needed five eights of a package of marbles for each gift bag. He had to make five gift bags. We are asked to find the number of packages of marbles that Vince needs.

To find the number of packages that Vince needs, we will multiply package needed for each gift with total number of gift packages.

$\text{Number of packages that Vince needs}=\frac{5}{8}\times 5$
