Question

A circle mirror has a diameter of 12 inches.
What is the area,in square inches, of the mirror?

Solution 1

For any circle, the area A =Â Ï€rÂ² (where r is the radius)

The radius is always half the length of the diameter.

Since our diameter is 12, our radius must be 6.

Let's plug 6 in for r in our equation.

A =Â Ï€(6)Â²

*6Â² = 6Ã—6 = 36*

**A = 36Ï€ inÂ²**

ForÂ Ï€ = 3.14...

A = 36Ã—3.14 =Â**113.04 inÂ²**

The radius is always half the length of the diameter.

Since our diameter is 12, our radius must be 6.

Let's plug 6 in for r in our equation.

A =Â Ï€(6)Â²

A = 36Ã—3.14 =Â

Question

Tom mowed lawns for the summer. In June he deposited $120 the first week, $80 the second week, and $75 the following week. Then the mower needed repairs, so Tom had to withdraw $30 from his account. How much money did he have left in his account at the end of June?

Solution 1

So, let's add up the total amount he made:

120 + 80 + 75 = 275

If he withdrew $30:

275 - 30 = 245

**Tom will have $245 at the end of June**

120 + 80 + 75 = 275

If he withdrew $30:

275 - 30 = 245

Question

A circle has a circumference of 361 pi what is the diameter of the circle.

Solution 1

Circumference =Â Ï€Â Â· d

"A circle has a circumference of**361 pi**"

Ï€ = pi

d = 361

**Answer = Diameter is 361**

Question

PLEASE ANSWER CORRECTLY ASAP: Solve this system of equations:
y = x2 â€“ 3x + 12
y = â€“2x + 14
Substitute the values of x, â€“1 and 2, into either original equation to solve for the values of y.
What are the solutions of the system of equations?
One solution is (â€“1, __ )
The second solution (2, ___)

Solution 1

First one, subsitute x=-1 for x

so one solution is (-1,16)

2nd one, subsitute 2 for x

the second soltuion is (2,10)

so one solution is (-1,16)

the second solution is (2,10)

so one solution is (-1,16)

2nd one, subsitute 2 for x

the second soltuion is (2,10)

so one solution is (-1,16)

the second solution is (2,10)

Question

Suppose there is a relationship between independent and dependent variables represented by a scatterplot. Which statement is correct? The independent variable influences change in the dependent variable only if the points on the scatterplot go up from left to right. The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right. The dependent variable influences change in the independent variable only if the points on the scatterplot go up from left to right. The dependent variable influences change in the independent variable whether the points on the scatterplot go up or down from left to right. Mark this and return

Solution 1

If there is a relationship between dependent and independent variables represented in a scatterplot, The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.

The independent variable is the one that influences the dependent variable. If there is a relationship between them, it doesn't matter the direction of the points in the scatterplot, but the correlation coefficient.

If the points go up from left to right, the correlation is called direct correlation (increasing the value of the independent variable will increase the value of the dependent variable).

If the points go down from left to right, the correlation is called inverse correlation (increasing the value of the independent variable will decrease the value of the dependent variable)

Have a nice day.

Answer:

B: The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.

dependent means it depends on something, such as the independent variable that will change it

Question

Aiden built a tower that is 18 inches tall and that is 3 times as tall as Anna tower.. Anna tower is 6 inches tall... Can you write an equation to match this story?

Solution 1

Let the height of theÂ tower be T

Let the height of the Anna tower be A

T =Â 3*A

You can also fit the values to check.

18 = 3*6

Let the height of the Anna tower be A

T =Â 3*A

You can also fit the values to check.

18 = 3*6

Question

A circle has a circumference of 49 pi what is the radius of the circle.

Solution 1

Circumference =Â Ï€D

Ï€D = 49Ï€

D = 49

Radius = Diameter Ã· 2 = 49 Ã· 2 = 24.5

**Answer: 24.5 units**

Ï€D = 49Ï€

D = 49

Radius = Diameter Ã· 2 = 49 Ã· 2 = 24.5

Solution 2

Circumference =Â Ï€Â Â· dÂ

49 = diameter

Ï€ = pi

Radius = Half of diameter

Divide radius by 2:

49Â Ã· 2 = 24.5

**Answer = Radius is 24.5**

~Hope this helped~

49 = diameter

Ï€ = pi

Radius = Half of diameter

Divide radius by 2:

49Â Ã· 2 = 24.5
