The radius of a circle is 3 centimeters. What is the circumference?Give the exact answer in simplest form. ___ centimeters (pi, fraction)

Let us take the unknown number as b.

Sum of the number and 8 can be represented as,

8 + b

Therefore, five time the sum is,

5(8+b)

This is equal to 4, so,

5 (8 +b) = 4

This is the required equation.

The number is,

The number is, -7.2.

Replacing x=1 in the equations to verify if the value of y is equal to 8, we have:

A.

y= 5*(1) + 3 = 8 (Multiplying and adding) (It is correct as the result for y is equal to 8)

y= 9*(1) - 1 = 8 (Multiplying and subtracting)(It is correct as the result for y is equal to 8)

B

y= 4*(1) + 2 = 6 ≠ 8 (Multiplying and adding) (It is not correct as the result for y is not equal to 8)

C

y= -2*(1) + 10 = 8 (Mulitplying and subtracting) (It is correct as the result for y is equal to 8)

y= 8*(1) + 1 = 9 ≠ 8 (Multiplying and adding) (It is not correct as the result for y is not equal to 8)

D.

y= 7*(1) -5 = 9 ≠ 8 (Multiplying and subtracting) (It is not correct as the result for y is not equal to 8)

The answer is the option A.

Answer:

y = 10x - 8

Step-by-step explanation:

The slope is "m", or how much the y-value changes on a line when the x-value changes by one.

The y-intercept is the y value of the line when it is intersecting the y-axis, or when the x-value is 0.

To find the slope, take 2 points from the graph and plug into the slope formula:

[tex]\frac{y_2-y_1}{x_2-x\\_1}[/tex]

I'll use (0, -8) and (1,2).

Plug into the formula.

[tex]\frac{2--8}{1-0}[/tex]

[tex]\frac{10}{1}[/tex]

10

Slope = 10

To find the y-intercept, look at the table. What is the y-value when the x-value is equal to 0?

-8

y-intercept: -8

Slope-Intercept form:

y = mx + b

m: slope

b: y-intercept

y, x: leave as variables

y = 10x - 8

SOLUTION

Given the question on the question tab;

The angle is 4.0

The angle that defines the arc is x = pi/4.

For a circle with a radius R, the area of an arc defined by an angle x is:

A = (x/2)*R^2

In this case, the diameter is 16km, then the radius is given by:

R =16km/2 = 8km

Then the area is:

A = (x/2)*(8 km)^2

And this must be equal to 8*pi km^2

Then we can solve the equation:

(x/2)*(8 km)^2 = 8*pi km^2

(x/2)*64 = 8*pi

x = 2*8*pi/64 = pi/4

That is the measure of the angle.

According to the table, the rate of change between 2018 and 2021 was 22.22%

A variable's rate of change over a predetermined amount of time. It is frequently used while discussing momentum and is typically represented as a ratio of one variable's change to another's corresponding change.

Given that,

Year Kids

2018   93

2019   92

2020  78

2021   75

2022   78

So, we have to calculate the rate of change between 2018 and 2021:

As we know, rate of change = (change in year / change in kids) × 100

rate of change = (4/ 18) × 100

rate of change = 22.22%

So, according to the table, the rate of change between 2018 and 2021 was 22.22%

Answer:

y = 75; z = 75

Step-by-step explanation:

105 and z are a linear pair and that means they add up to 180

they are on a straight line which is why they are a linear pair

105 + z = 180

subtract 105 to both sides

z = 75

now add all of the remaining sides and subtract that from 360 because a quadrilaterals angles add to 360

75 + 89 + 95 = 259

360 - 259 = y

360 - 259 = 101

y = 101

these are your answer

18/35 fraction of students are girls who brought their lunch today.

A fraction is a mathematical concept that denotes a component of a whole or, more generally, any number of equal parts. A fraction, such as one-half, eight-fifths, and three-quarters, denotes the number of components of a specific size when used in conversational English.

Let's say,

Total number of students over school = x

Number of girls = (6/7)x

Number of girls who brought their lunch = 3/5 of (6/7)x

⇒ 3/5(6/7)x

⇒ (18/35)x

Hence "18/35 fraction of students are girls who brought their lunch today".

Answer:1/4 or 0.25/1

Step-by-step explanation:

In 1 kilometer there are a thousand meters. So 250 is a quarter of 1000 which makes the fraction 1/4 or 0.25/1 whichever you need.

The function B has a greater rate of change.

What is rate of change?

How quickly something changes over time is referred to as its rate of change, or ROC. Therefore, rather than the size of each change individually, it is the rate—or the acceleration or deceleration of changes. In finance, rate of change is employed to comprehend price returns and spot trend momentum.

First to find the rate of change for function A.

Rate of change = [tex]\frac{0-5}{2.5-1.5} = \frac{-5}{1}=-5[/tex]

Function A has rate of change is -5.

Now consider, the second equation

y = -4.5x + 15

Since, the slope is rate of change for the equation.

So, function B has rate of change of -4.5

Now compare the rate of change for both the functions A and B

-5 < -4.5

Therefore, function B have greater rate of change.

We know that:

- The company offered him $46,000 per year plus 3% of his total sales.

- the average pay for this job is $64,000

And we must find what would be the sales of Andre for his pay to be at least as high as the average pay for this job

To find it we can use a equation that represents the situation

We can use the next formula

Analyzing the given information we know that

- avergare pay = 64000

- base salary = 46000

- 3% of total sales = 3% * x = 0.03 * x (x represents the total sales)

Now, replacing the values in the formula

Since x represents the total sales we need to solve the equation for x

ANSWER:

Step-by-step explanation:

coordinates (-100,0) and (100,0)  missing in Question

The center of the hyperbola  is  (0,0)  = (h, k)

c = the distance form the center to either focal point  = 100

c² =  100²   =  10000

The differences  from the receiver to the transmitters  =  2a

2a =  180

How to add fractions,

Answer:

2x + -3y = 19

Step-by-step explanation:

In this question, they already gave you the equation of the line. But it is in point-slope form. We just need to rearrange the equation to look like:

Ax + By = C

A and B and C should be positive or negative whole numbers. So let's get rid of the fraction first.

y + 1 = 2/3 (x - 8)

You could use distributive property on the right side, but that is just going to make two terms have fractions. Instead, let's multiply both sides by 3 and get rid of the fraction.

3(y + 1) = 3• 2/3(x-8)

3(y + 1) = 2(x - 8)

Now use distributive property.

3y + 3 = 2x - 16

We need x and y on the left and plain numbers on the right.

3y + 3 = 2x - 16

Subtract 3

3y = 2x - 19

Subtract 2x

3y - 2x = -19

Rearrange the x and y terms, put x in the lead.

-2x + 3y = -19

This is almost standard form. The A is supposed to be positive. So change the sign of ALL the numbers. A is 2, the B is -3 and the C is 19. Those are the numbers that go in the blanks on your question.

The statements the polygon has 144° rotational symmetry, The polygon has point symmetry and The polygon has 36° rotational symmetry are true.

We have to find the symmetry.

A decagon is given as

Number of sides = 10

So rotational symmetry = [tex]\frac{360^{0} }{n}[/tex]

= [tex]\frac{360 }{10}[/tex]

= 36°

So rotational symmetry angles are multiple of 36°

So 36° x 4 = 144° is a rotational symmetry.

The all sides are congruent, so decagon as point symmetry.
