Solve the word problem. Round your final result to the nearest hundredth.

fenix001 [56]

Answer:

1)Area of circle: 64 $\pi$

2)Area of semicircles: 128 $\pi$

3)Area of quarter-circles: 128 $\pi$

4)Total area of pattern: 320 $\pi$

Step-by-step explanation:

r = 8cm

Given: 1 circle, 4 semicircles, and 8 quarter-circles.

Area of a circle: $\pi r^{2}$

1) A = $\pi r^{2}$ where r = 8

A = 64 $\pi$

2) 4 semicircles = 2 circles

so the answer is 2*A = 128 $\pi$

3) 8 quarter-circles = 2 circles

Therefore, the answer here is the same as the answer for #2!

4)There are 5 circles total because:

1 circle = 1 circle

4 semicircles divided by 2 = 2 circles (because $\frac{1}{2}$ times 4)

8 quarter-circles divided by 4 (think about what "quarter" means) = 2 circles

So ... 1 + 2 + 2 = 5 circles

Now we need to find the area of 5 circles which is just 5*A

5*A = 320 $\pi$

An executive invests $26,000, some at 8% and some at 6% annual interest. If he receives an annual return of $1,860, how much is

S_A_V [24]

Let x = amount invested at 8%
26000 - x = amount invested at 6%

0.08x + 0.06(26000 - x) = 1860

solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000

7.5% would be 405. Honestly to find it quickly, i took 10% of 5400,which is 540 and divided that by 4 to get 135 and multiply that by 3 to get 7.5%, which is 405 increase. to get the money total add 405 to 5400 to get 5805
