Answer:

42: 1, 2, 3, 6, 7, 14, 21, 42

43: 1, 43

Step-by-step explanation:

Answer:

A.Linear

B.exponential

C.exponential

D.quadratic

Answer:

A=Quadratic B=Exponential C=Quadratic D=Quadratic  

Step-by-step explanation:

Quadratic equations follow the formula ax^2+b+c and sometimes c or the third digit in the equation may not be there so C=0.

Exponential equations have exponents that are added to another exponent and supported by the base/coefficient.

Linear Equations have a specific formula which is Ax+By=C such a 2x+4y=8 and solve for both x and y.

There were no linear equations because none were solving for x and y, but most were quadratic equations and one exponential equation.

Answer:

3/5

Step-by-step explanation:

Answer:

66%

Step-by-step explanation:

0.6 repeating is 66%.

From decimal to percent:

To get a percent from a decimal number, move the decimal over twice to the right. In this case, 0.66 would become 66% because the decimal moved to the right twice.

From decimal to fraction to percent:

I already know that 2 divided by 3 is 0.6 repeating. 2 divided by 3 could also be written as [tex]\frac{2}{3}[/tex]. So the first step is complete, from the decimal 0.6 repeating to the fraction [tex]\frac{2}{3}[/tex]. Now from [tex]\frac{2}{3}[/tex] to a percent. If you get a 2 out of 3 ([tex]\frac{2}{3}[/tex]) you would get a 66%.

yes because it would give you numbers that you could then use to make some sort of chart to better understand your data

Part A: She needs to collect different types of data to form her classmates. It will help her to find which student spends the most time playing video games.

Part B: Yes, it is a statistical question.

What Zoe needs to do?

Zoe needs two main data from each of her classmates.

1. Name of her classmates.

2. Which student spends how much time playing video games.

After that, she can make a graph or a chart in order to understand which student spends more time playing video games.

Answer:

[tex]V=4500\pi\ in^3[/tex]

Step-by-step explanation:

Given that,

The radius of a ball, r = 15 inches

We need to find the volume of a ball. The ball is in the shape of a sphere. The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Put all the values,

[tex]V=\dfrac{4}{3}\pi \times (15)^3\\\\V=4500\pi\ in^3[/tex]

So, the volume of the ball is equal to [tex]4500\pi\ in^3[/tex].

Answer:

[tex]Area= 8[/tex]

Step-by-step explanation:

Given

[tex]I = (-9,-8)[/tex]

[tex]J = (-5,-6)[/tex]

[tex]K = (-7,-3)[/tex]

The complete part of the question is to calculate the area of IJK

The area is calculated using:

[tex]Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 + x_3y_1 - x_1y_3 |[/tex]

Where:

[tex]I = (-9,-8)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]J = (-5,-6)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]K = (-7,-3)[/tex] --- [tex](x_3,y_3)[/tex]

So, we have:

[tex]Area = \frac{1}{2}|(-9*-6) - (-5*-8) + (-5*-3) - (-7*-6) + (-7*-8) - (-9*-3) |[/tex]

Solve the brackets

[tex]Area = \frac{1}{2}|54 - 40 + 15- 42 + 56 - 27 |[/tex]

[tex]Area = \frac{1}{2}|16|[/tex]

The absolute value of 16 is 16

So:

[tex]Area = \frac{1}{2} * 16[/tex]

[tex]Area= 8[/tex]

Answer:

d = 5t^2

Step-by-step explanation:

"d is directly proportional to the square of t"

d = kt^2

To find k use

"The ball falls 20 metres in a time of 2 seconds."

20 = k(2^2)

20 = k(4)

Divide both sides by 4

5 = k

Using k = 5 the formula becomes

d = 5t^2

Answer:

(6, 0)

Step-by-step explanation:

x+3y=6

x=6-3y

subsitute x into the first equation

(6-3y)+3y=6

6-6y=6

-6y=0

y=0

Do the next equation

x=6-3(0)

x=6

Answer:

[tex]V = 288\pi[/tex]

Step-by-step explanation:

Given

[tex]r = 6[/tex]

Shape: Sphere

Required

The volume

The volume of a sphere is calculated using;

[tex]V = \frac{4}{3}\pi r^3[/tex]

Substitute 6 for r

[tex]V = \frac{4}{3}\pi * 6^3[/tex]

[tex]V = \frac{4}{3}\pi * 216[/tex]

Divide 216 by 3

[tex]V = 4\pi * 72[/tex]

[tex]V = 288\pi[/tex]

Answer:

320 milligrams of sodium

Step-by-step explanation:

Create a proportion where x is the milligrams of sodium a 20 ounce bottle has:

[tex]\frac{96}{6}[/tex] = [tex]\frac{x}{20}[/tex]

Cross multiply and solve for x

1920 = 6x

320 = x

So, a 20 ounce bottle will have 320 milligrams of sodium

Answer:

The width of the banner is 4 inch and the length of the banner is  28 inch

Step-by-step explanation:

Given

Length is seven times its width

Let the width be "X", then length would be 7X

The banner is of rectangular shape.

Its area is 112 square inches

[tex]X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4[/tex]

Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch
