The original number would be 50 because 3/10 = 15/x and 10x5 is 50

sarah invests £9600 at a simple interest rate of 8% per year. Work out the value of the investment after 3 years

Bess [88]

Answer:

£11,904

Step-by-step explanation:

Simple interest = PRT/100 where P = initial investment, R = rate and T = time.

So interest on £9600 = 9600*8*3/ 100

= £2304

So the value after 3 years = 9600 + 2304

= £11,904 (answer)

A car has a windshield wiper on the driver's side that has total arm length of 10 inches. It rotates

son4ous [18]

Answer:

75.44 Square Inches

Step-by-step explanation:

The diagram of the problem is produced and attached.

To determine the area of the cleaned sector:

Let the radius of the larger sector be R

Let the radius of the smaller sector be r

Area of the larger sector $=\frac{\theta}{360}X\pi R^2$

Area of the smaller sector $=\frac{\theta}{360}X\pi r^2$

Area of shaded part =Area of the larger sector-Area of the smaller sector

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

From the diagram, R=10 Inch, r=10-7=3 Inch, $\theta=95^\circ$

Therefore, Area of the sector cleaned

$=\frac{95 \pi}{360}X (10^2- 3^2)\\=75.44$ Square Inches$
