Answer:

37.7 feet would be your answer

Step-by-step explanation:

circumference = pi * diameter

circumference of metal frame = pi * (diameter of metal frame)

(diameter of metal frame) = 12

Circumference of Metal Frame = 3.14 * 12 = 37.68

therefore D: 37.7 feet would be your answer

90 - 23 = 67, 67 = 4x - 9, 76 = 4x, 76 / 4 = 19

Answer:

8.The residents of New Jersey would be Population

Residents of Ocean Country would be Sample

9. 4 cards would be sample

All cards in a deck would be population

What is the difference between the two?

Believe it or not, there are differences between the two. Population is the WHOLE THING of what you are looking at. Sample, however, is just a very small peice in the whole picture.

How can I tell the difference?

You can tell the difference by thinking about it logically. Ask yourself these questions. Is there a bigger thing involved?, Can I find something bigger?, etc.

I hope this helps you!

Answer:

1. y=|x−3|+|x+2|−|x−5|, if -2<x< 3  = x

2. y=|x−5|+|x+5|, if x>5 = 2x

3. y=|x−5|+|x+5|, if x<−5 = -2x

4. y=|x−5|+|x+5|, if −5<x<5 = 10

Modulus value means it always gives positive value. Therefore,

Step-by-step explanation:

if x < a, then |x - a| is positive when |x - a | = a -x, which is positive as a is larger than x.

and if x >a, then |x-a| is positive when |x-a| = x - a, which is positive as a is smaller than x.

Applying the same,

(1) for  -2 < x < 3,

|x - 3 | = 3 - x, as x <3

| x + 2 | = | x - (-2)| = x - (-2) = x+2 as x> -2

| x - 5 | = 5 -x , as x < 5

therefore, y = |x−3|+|x+2|−|x−5| = 3 - x + x + 2 - (5 - x) = x

(2) for x > 5,

|x - 5|= x - 5

|x  + 5| = | x - (-5)| = x + 5

therefore y = x - 5 + x + 5 = 2x

(3) for x < -5,

|x - 5| = 5 - x

|x + 5| = |x - (-5)| = -5-x

therefore y = 5 - x + -5 -x = -2x

(4) for -5< x < 5,

|x -5| = 5 - x

|x +5| = x + 5

y = 5 - x + x + 5 = 10

Answer:

C

Step-by-step explanation:

Line slope calculation formula: The difference of the second components is divided by the difference of the first components. It should be noted that they are reduced in order. The components of a point on the numerator and denominator must always be written first.

Answer:

A.

Step-by-step explanation:

1) the line provided on the graph is y= -4x-2, then

2) the corrrect answer is A:-2y>8x+4.

Answer:

The answer is D

Step-by-step explanation:

When you have an exponent on a number it just means that number must be multiplied by itself as many times as the exponent says.

Example: 6^2 this just means 6*6 since the exponent is 2.

Now for this question since the exponent is 4 you get your expression 6^4 or 6*6*6*6.

Hope this helped.

Answer:

n=12

Step-by-step explanation:

1/6n=2 we multiple both sides by 6/1

2*6=12 so n=12

Answer:

n = 12

Step-by-step explanation:

If 1/6 of n = 2 that means 1/12 of n = 1

You can work this out by turning n into 1 instead of 2 by dividing by 2. You have to then divide 1/6 by 2 and half of 1/6 is 1/12. Therefore, 1/12 of n = 1

You can then do 1 x 12 which equals 12

Overall, n = 12

Answer:

[tex]\huge\boxed{\bf\:0.5 \: dollars }[/tex]

Step-by-step explanation:

Given,

We need to find the unit price OR the price of 1 plastic cup.

To find this, we need to divide the cost of the total nunber of cups bought by the number of cups bought. Then,

Cost of 1 cup

= Cost of 9 cups/9

= 4.51 / 9

= $ 0.5 (rounded price)

[tex]\rule{150}{2}[/tex]

Answer:

50 cents or $0.50

Step-by-step explanation:

c = the cost of each plastic cup, the unit price.

9c = 4.51

/9     /9

c = $0.50 per cup

Each cup costs 50 cents or $0.50

Answer:

Number 8: The medium pizza is 19 inches bigger than the personal sized.

Number 9: The window will take up about 37.7 feet.  

Step-by-step explanation:

For number 8, you want to multiply the 16 inches by pi, and you would get an estimate of 50. Then you do the same thing for ten inches and you get an estimate of 31. Subtract the two estimates and you will get 19. Therefore, with the rounded up to a whole number estimate, the medium sized pizza is 19 inches bigger than the personal sized one.

For number 9, you want to multiply that radius, which is 6, by two to get your diameter. Then you want to multiply that to get your circumference, which would be a rounded up to the tenth place estimate of 37.7 feet.

I hope all of this helps you!

Answer:

8. 19 in.

9. [tex]113\ ft^2[/tex]

Step-by-step explanation:

8a. medium-sized pizza

d/2 = 2

r = 16/2 = 8 in.

C = 2*π*r

C = 2*3.14*8

C = 16*3.14

C = 50.24 in.

8b. personal-sized pizza

d/2 = 2

r = 10/2 = 5 in.

C = 2*π*r

C = 2*3.14*5

C = 10*3.14

C = 31.4 in.

50.24 in. - 31.4 in = 18.84 in.

19 in. (rounded to the nearest whole number)  <== final answer

9. Area of a circle: [tex]\pi r^2[/tex]

A = [tex]3.14* 6^2[/tex]

A = 3.14 * 36

A = [tex]113.04\ ft^2[/tex]

A = [tex]113\ ft^2[/tex] (rounded to the nearest tenth) <== final answer

Answer:

Perimeter: 6+[tex]9\sqrt{2}[/tex] units

Area: 13.5 [tex]units^{2}[/tex]

Step-by-step explanation:

I wasn't sure what to estimate to...

for perimeter use: [tex]a^{2} +b^{2} =c^{2}[/tex]

I noticed that the trapezoid was made up of 3 identical triangles, so find the area of one of them times 3

one triangle area: [tex]\frac{1}{2}[/tex] (b · h)    b = base, h = height

plug- in values, so [tex]\frac{1}{2}[/tex] (3 · 3) is half of 9 which is 4.5.

3 · 4.5 is 13.5

Answer: I'd say the third graph seems correct, if its not the third graph then the fourth graph

Hii

Now, in order to figure out which graph it is, we need to solve the problem.

Say someone bought 1 cup of orange juice. That would be 2$. Say they wanted a refill,that would be 3$. And so on

The first graph  states that they got 5 refils, so the 2$ to get the orange juice, plus 5. That would be 7$. So the first graph is incorrect.

The second graph states that they got 9 refills. So the 2$ to get the orange juice, then 1$ for each refill, so 9$. So 11$.

The third graph states that someone got 4 refills. So, 2$ to get the cup. Then an extra 1$ for every refill. So 4$,plus 2$ is 6$

The fourth graph states that they got 8 refills. So the 2$ to get the cup, plus the 1$ each refill, since they got 8 refills, it would be 8$, So 10$.

Since the fourth graph was the only graph that showed the right cost of orange juice, this is correct
