1 answer:

3 0

The solution is x=2 y=6. First,you have to rearrange the second equation then rewrite it under the other one. Then, solve for y using elimination. Finally, plug y in to the original to solve for x. It has one solution.

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$

The sum of two numbers is 300 and the two numbers have a ratio of 20:10. Find the larger number.

Komok [63]

Step-by-step explanation:

Let the two numbers be 20x and 10x

Then by the question,

20x + 10x = 300

or, 30x = 300

or, x = 300/ 30

x = 10

Now the larger number

20x = 20* 10 = 200.

Hope it will help you :)
