Step-by-step explanation:

Area of a Circle

Given a circle of radius r, the area is calculated by the formula:

[tex]A=\pi\ r^2[/tex]

There are two circles in the diagram. The outer circle has a radius of r1=2x, thus its area is:

[tex]A_1=\pi\ (2x)^2[/tex]

The interior circle has a radius of r2=6 cm, thus its area is:

[tex]A_2=\pi\ 6^2=36\pi[/tex]

The shaded area is obtained by subtracting A1-A2:

[tex]A=\pi\ (2x)^2-36\pi[/tex]

The value of the shaded area is given as 220π cm2. Equating:

[tex]\pi\ (2x)^2-36\pi=220\pi[/tex]

Dividing by π:

[tex](2x)^2-36=220[/tex]

Adding 36:

[tex](2x)^2=220+36=256[/tex]

Taking square root:

[tex]2x=\sqrt{256}=16[/tex]

Dividing by 2:

x = 8 cm

Answer:

Rewrite the absolute value equation as four equations without absolute value bars.

5z−2=z+65−2=−(z+6)−(5z-2)=z+6−(5z−2)=−(z+6)

After simplifying, there are only two unique equations to be solved.

5z−2=z+65z−2=−(z+6)

Solve

5z−2=z+6 for z.

z=2

Solve

5z−2=−(z+6)for z.

Tap for more steps...

z=−23

List all of the solutions.

z=2,−23

The result can be shown in multiple forms.

Exact Form:

z=2,−23

Decimal Form:

z=2,−0.6

Step-by-step explanation:

it is 0.6

Step-by-step explanation:

I believe it's this one. I have the same exact question :))

Answer: 30 + 45 = 15(2 + 3)

Step-by-step explanation:

The greatest common factor for 30 and 45 will be gotten as follows:

Factor of 30 = 2 × 3 × 5

Factor of 45 = 3 × 3 × 5.

GCF = 3× 5 = 15

Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:

30 + 45 = 15(2 + 3)

Answer:

Step-by-step explanation:

1. x^2-x-20=3x-15

x=5, x=1 substitute

y=3*5-15 = 0

y=3*(-1)-15 = -18

Solution: (5,0) & (-1,-18)

2. x^2+2x+3=x+5

x=-2, x=1 substitute

y= -2+5 = 3

y=1+5 = 6

Solution: (-2,3) & (1,6)

Answer:

Answer:

Step-by-step explanation:

An exterior angle of a triangle is formed by any side of a triangle and the extension of its adjacent side. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. Find the values of x and y in the following triangle. y + 92° = 180° (interior angle + adjacent exterior angle = 180°.)

Answer:

330.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 11%/100 = 0.11 per year,

then, solving our equation

I = 1500 × 0.11 × 2 = 330

I = $ 330.00

The simple interest accumulated

on a principal of $ 1,500.00

at a rate of 11% per year

for 2 years is $ 330.00.

Answer:

y = 6/5x

4. your final answer is [tex]\frac{6}{5}[/tex]

Answer:

20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

WOW, that's a lot of points!!

To find the answer for this problem, you take 80% of 50.

In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Answer:

500,000

Step-by-step explanation:

The nearest hundred thousand is the first 5

In rounding when something is 4 or lower it becomes a zero and if it is 5 or higher it is goes up to the next number for example if it is rounded to the nearest ten, and the number is 338, it would be 340
