For the 3 circles, in increasing order of the radius, we have:

For a circle of radius R, the arc defined by an angle θ (in degrees) is given by:

L = (θ/360°)*2pi*R

Where pi = 3.14

In this case, we have 3 circles of different radius, and θ = 60°, then we have:

circle 1:

radius = 1 unit, then:

L₁ = (60°/180°)*2*3.14*1 = 2.09

circle 2:

radius = 2 units, then:

L₂ = (60°/180°)*2*3.14*2 = 4.18

circle 3:

radius = 3 units, then:

L₃ = (60°/180°)*2*3.14*3 = 6.28

Answer:

x=5

Step-by-step explanation:

.

Answer:

so i have a little trick for you.  Reflecting across the x axis is just turning (x,y) to (x, -y)

Reflecting across the y axis is just turning (x, y) to (-x, y)

If we substitute that in we can figure it out

so

(0, 3) we have to turn it to (x, -y), so it would end up being (0, -3). That is the reflection axross the x axis.

(-4,5) we have to turn it to (-x,y) which will be (4,5) because a negative and a negative is positive. so (4,5) is the ordered pair reflected across the y axis! Hope it helps :D

Answer: 38

Step-by-step explanation:

Since the polygons are similar, the corresponding sides are all in the same proportions.

x-2/4.5 = 16/2 = 48/6

Solving for x

Step-by-step explanation:

Factorize x² - 5x + 6

x² - 5x + 6 = x² - 3x - 2x  + 6

Answer:

20° and 70°

Step-by-step explanation:

complimentary angle sum to 90°

let x be the compliment then the angle is 3x + 10 , so

x + 3x + 10 = 90 , that is

4x + 10 = 90 ( subtract 10 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20

3x + 10 = 3(20) + 10 = 60 + 10 = 70

the 2 angle measures are 20° and 70°

Answer:

Suppose we want to divide 3 by 2.

By Long Division we first write 1 as the first digit as the quotient, then we subtract 2 from 3, then we add a zero to the remainder 1, and then add a decimal point after the quotient 1, then write 5 after the decimal point, getting the quotient as 1.5

I know it is indeed right as we can verify. But why do we add a zero and the decimal point in the quotient?

Thank you.

Answer:

less

Step-by-step explanation:

Dividing a decimal number that is less than 1 gives a quotient that is larger than the dividend.

For example :

Take 3/0.3 :

⇒ 3 / 0.3

⇒ 10

10 is greater than the dividend 3.

The number 4 represents the initially held water of the bucket. Then the correct option is B.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bucket holding several inches of water was placed under a leaking faucet.

Water leaking into the bucket so that the level of the water in the bucket increased by a certain number of inches per hour.

The equation y = 2x + 4 represents this situation, where x is the number of hours and y is the number of inches of water in the bucket.

Then the number 4 in the equation represents.

The number 4 represents the initially held water of the bucket.

Answer:

the answer for 500×4-8/2 is 1996

The distance that the car travel over an angle of 2pi/3 radians is 52.3 feet

The formula for calculating the length of an arc is expressed as:

L = r theta

Given the following parameters

r is the radius. = 25ft

theta is the angle subtended = 2pi/3 radians

Substitute

L = 25 * 2pi/3
L = 50pi/3
L = 52.3 feet

Hence the distance that the car travel over an angle of 2pi/3 radians is 52.3 feet
