Step-by-step explanation:

Required

Select matching pairs

Represent diameter with D and Circumference with C

C is calculated as:

[tex]C = \pi D[/tex]

Where

[tex]\pi = 3.142[/tex]

A. D = 5m; C = 22m

Using: [tex]C = \pi D[/tex]

[tex]C = 3.142 * 5[/tex]

[tex]C = 15.71[/tex]

15.71 does not approximates to 22m.

Hence, the pair do not match

B. D = 19 in; C = 60 in

Using: [tex]C = \pi D[/tex]

[tex]C = 3.142 * 19[/tex]

[tex]C = 59.698[/tex]

59.698 approximates to 60.

Hence, the pair match

C. D = 33 cm; D = 80 cm.

Using: [tex]C = \pi D[/tex]

[tex]C =3.142 * 33[/tex]

[tex]C =103.686[/tex]

103.686 does not approximates to 22m.

Hence, the pair do not match

From the analysis above, only option B matches the diameter with the circumference

I can't actually see the graph but i'll try to help

Step-by-step explanation:

if we use the formula y=mx+b

b=initial registration fee

x=amount of months charged

y=total sum paid

So you fill in the formula using the values on the graph

Colleen needs to raise $37.5 to reach her goal.

In mathematics, the arithmetic operation has four main operators such as addition, subtraction, multiplication, and division.

The symbol of + represents addition.

The symbol of - represents subtraction

The symbol of × represents multiplication

The symbol of ÷ represents division.

The goal of Collen is 40 tubs.

3/4 of 40 = 30 tubs.

Money for 30 tubs

⇒ 30 × 3.75 = $112.5

She needs

$150 - $112.5 = $37.5

Hence " Colleen needs to raise $37.5 to reach her goal".

Answer:

h ≥ -1

Step-by-step explanation:

i took a quiz and got it right

hope this helps :)

Answer:

The basic rule is: If you need to convert from a larger unit to a smaller unit, multiply. If you need to convert from a smaller unit to a larger unit, divide. You will make the number smaller and, as you already know, division is all about making numbers smaller.

Answer:

addiemoss23/this person wrote this NOT me, it is right btw

Step-by-step explanation:

To convert units into smaller units, multiply. When the units are smaller , you need more of them to express the same measure. To convert smaller units to larger units, divide. When the units are larger , you need fewer of them to express the same measure.

Step-by-step explanation:

You may use this formula to find the slope of a line going through points [tex](x_1,y_1) \text{ and } (x_2,y_2)[/tex]:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Notice the numerator is just a subtraction of the y's while the denominator is a subtraction of the x's. The order you choose your y's on top will matter to how you subtract the x's.

You could just line up the points and remember that the y difference goes on top and the x difference goes on bottom.

This is my favorite way.

(-1  ,   -2)

minus

(2  ,     7)

---------

-3      -9

The slope is -9/-3 or 3.

You could do it the other way:

(2   ,    7)

minus

(-1   ,    -2)

--------------

3           9

The slope is 9/3 or 3.

Answer:

y = 9 + -1x + 5x2

Step-by-step explanation:

Simplifying

4y + -7 = 5x2 + -1x + 2 + 3y

Reorder the terms:

-7 + 4y = 5x2 + -1x + 2 + 3y

Reorder the terms:

-7 + 4y = 2 + -1x + 5x2 + 3y

Solving

-7 + 4y = 2 + -1x + 5x2 + 3y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3y' to each side of the equation.

-7 + 4y + -3y = 2 + -1x + 5x2 + 3y + -3y

Combine like terms: 4y + -3y = 1y

-7 + 1y = 2 + -1x + 5x2 + 3y + -3y

Combine like terms: 3y + -3y = 0

-7 + 1y = 2 + -1x + 5x2 + 0

-7 + 1y = 2 + -1x + 5x2

Add '7' to each side of the equation.

-7 + 7 + 1y = 2 + -1x + 7 + 5x2

Combine like terms: -7 + 7 = 0

0 + 1y = 2 + -1x + 7 + 5x2

1y = 2 + -1x + 7 + 5x2

Reorder the terms:

1y = 2 + 7 + -1x + 5x2

Combine like terms: 2 + 7 = 9

1y = 9 + -1x + 5x2

Divide each side by '1'.

y = 9 + -1x + 5x2

Simplifying

y = 9 + -1x + 5x2

Answer:

D

Step-by-step explanation:

The arithmetic sequence with a common difference of 2 is 13,15,17,19. The correct option is D.

The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression.

A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.

The common difference is equal to 2. The arithmetic sequence will be written as,

13,15,17,19

Therefore, the arithmetic sequence with a common difference of 2 is 13,15,17,19. The correct option is D.

Step-by-step explanation: "rise over run"/vertical ( l ) over horizontal ( -- )

Answer:

First Graph: 1

Second Graph: 1/2

Step-by-step explanation:

Rise over run

Look at where the line intersects with the other line perfectly and find the two closest times when that happens, then go up and over and count it.

So for the first one it is: up 1 over 1. That as a fraction is, 1/1 and that equals 1. So the slope is 1.

For the second one it is up 1 over 2. That as a fraction is 1/2. So the slope is 1/2.

Answer:

103

Step-by-step explanation:

Answer:

y = -2x + 6

Step-by-step explanation:

Since we already have the slope we just need to find the y-intercept.

To do that just plug in the point you were given. (1,4)

4 = -2(1) + b (b represents the y-intercept)

4 = -2 + b (add 2 on both sides)

6 = b

y = -2x + 6 is the equation

Hope this helps!!

Answer:

The equation (in y=mx+b form) would be y= -2x+6

Step-by-step explanation:

The slope is given from the start, which is -2, so you would plug that in for m to make the equation y=-2x but this IS NOT YOUR ANSWER

I was able to graph it, although there are multiple ways to do this.

Next you have to find the y-intercept. You use your coordinate (1,4) and go up twice (positive) (1,6) and go to the left (negative) to get the point (0,6) giving you your intercept.

Plugging it into the equation for b, your equation would now be y= -2x + 6 giving you your final answer

Step-by-step explanation:

Area of the square = a²

= 20²

= 400cm²

Area of the circle = πr²

= 22/7 × 9²

= 22/7 × 81

= 254.57cm²

Area of the shaded region = Area of the square - Area of the circle

= 400cm² - 254.57cm²

= 145.43cm²

Answer:

76

Step-by-step explanation:

median is the number in the very center of the list of numbers in order:

64, 72, 72, 80, 85, 89

to find the one in the middle we take away the numbers from both ends:

72, 72, 80, 85

72, 80

since there are two numbers in the middle we’ll find the average

(72+80)/2

152/2

76

Answer:

76

Step-by-step explanation:

Median means middle

so we are looking for the middle number

place the numbers in order and look for the number thats in the middle

64, 72, 72, 80, 85, 89

72 and 80 are both the middle numbers.

Therefore, we add 72+80 and then divide by 2

72+80= 152

152/2= 76

Final answer: 76 is the median
