Ill Mark Brainliest if you answer correctly. The figure below shows a shaded circular region inside a larger circle:

pogonyaev

First we have to find the areas of both circle using the formula

$Area = \pi r^2$

For larger circle,

$Area= \pi(5)^2 = 25 \pi$

For smaller circle,

$Area = \pi (4)^2 = 16 \pi$

Required probability

$= \frac{25 \pi -16 \pi}{25 \pi} *100 = \frac{9}{25}*100 = 36%$

Correct option is the second option .

Kinda need help anything helps

katovenus [111]

First you have to find the slope with the equation y2 - y1 / x2 - x1 , then once you have found the slope (slope = -2) you simply plug it into the point slope formula. y-0 = -2(x-5) solving it algebraically you should arrive at Y=-2x+10. (the 5 and 0 were plugged in are two of the X and Y points of the line which is why we plugged them into the X and Y values of the equation)

The area of a triangular-shaped rug is 21 square yards and the height is 3 yards. Find the base.

tresset_1 [31]

Answer:

14 yards

Step-by-step explanation:

the area of a triangle is 0.5×b×h

plug in what you have

0.5×b×3=21

(3x0.5)b=21

1.5b=21

b=21/1.5

b=14

Write an equation in standard form given: m= -3/4 and b=5.

Dmitry [639]

Answer:

3x+4y=20

Step-by-step explanation:

The slope-intercept equation would be:

y=mx+b

y=-3/4(x)+5

But standard form is

ax+by=c

We can obtain this by moving the -3/4(x) to the left side

$\frac{3x}{4} +y=5$

Multiply both sides by 4 to get rid of the fraction

3x+4y=20
