Noah scored 20 points in a game. Mai's score was 30 points. The mean score for Noah, Mai, and Clare was 40 points. What was Clare's score? Show your work.
I need this answer ASAP.

Answers

Answer:

Clare's score was 70.

Step-by-step explanation:

N = 20

M = 30

C = ?

Mean = (Sum of all values)/3

40 = (20 + 30 + c)/3

40 = (50 + c)/3

50 + c = 120

c = 70

Answer:

70

Step-by-step explanation:

Let's think about this backwards. The mean of all 3 points is 40, so that is our answer. We instead of dividing would multiply. We would multiply by 3 'cause that's how many numbers there are. We would get 120. Finally, we would                                                                                                    

                                                                                      3

have to subtract. We will do this problem:

20 + 30 = 50

120 - 50 = 70

So, we get our answer of 70!

__

Let's check our work!

20 + 30 + 70 = 120 = 40

         3               3

__

Let's explain our work propproperly:

First, I took the mean and multiplied it by three because we have Noah, Mai, and Clare. Next, I added 20 and 30 to get an answer of 70 which is the answer. In conclusion, Clare's points are 70 points.

Then, look at the column between 2 and 2 2/8. You see that there are 2 books that weigh 2 1/8 pounds.

Miles is throwing three darts at the board shown below. His score is the sum of all three darts. How many different possible total scores could Miles get with all three darts?

A) 450
B) 46
C) 12
D) 10

Answers

Answer:To find the number of different possible total scores that Miles could get with all three darts, we need to consider all of the different combinations of scores that Miles could achieve with each dart.

The board is divided into four sections, each with a different score value:

The red section is worth 3 points

The green section is worth 2 points

The blue section is worth 1 point

The white section is worth 0 points

For each dart, Miles has the option to throw it at one of these four sections, which means that he has four possible scores he could achieve with each dart. Therefore, with three darts, Miles has a total of 4 * 4 * 4 = 64 different combinations of scores that he could achieve.

For example, Miles could throw all three darts at the red section and score 3 + 3 + 3 = 9 points. Or, he could throw two darts at the green section and one dart at the blue section and score 2 + 2 + 1 = 5 points.

In total, Miles has 64 different possible total scores that he could get with all three darts.

Figure Q has undergone a dilation
Which scale factor was used for the dilation?
A. 1/2


B. 3

C. 1/3


D. 2

Answers

Answer: 2

Step-by-step explanation: the figure has increased by 2 by x and y

What is Dilation?

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

An example of dilation math is a square of side 5 units can be dilated to a square of side 15 units, but the shape of the square remains the same.


Dimensions of Object Q are as follows:

(3 1/3,1)

(3 1/3,2)

(1,1)

(1,2)

Dimensions of Object Q’ are as follows:

(6 2/3,2)

(6 2/3,4)

(2,2)

(2,4)

Dimensions of Object Q to Object Q’ are as follows:

(3 1/3,1) ⇒ (6 2/3,2)

(3 1/3,2) ⇒ (6 2/3,4)

(1,1) ⇒ (2,2)

(1,2) ⇒ (2,4)


Let’s consider each vertex one by one.

The x-coordinate 3 1/3 changed to 6 2/3 and the y-coordinate 1 changed to 2. This shows that both the coordinates of Q’ became twice the coordinates of Q.The x-coordinate 3 1/3 changed to 6 2/3 and the y-coordinate 2 changed to 4. This shows that both the coordinates of Q’ became twice the coordinates of Q.The x-coordinate 1 changed to 2 and the y-coordinate 1 changed to 2. This shows that both the coordinates of Q’ became twice the coordinates of Q.The x-coordinate 1 changed to 2 and the y-coordinate 2 changed to 4. This shows that both the coordinates of Q’ became twice the coordinates of Q.

Therefore, the scale factor in this dilation is 2.

So, the correct option is Option (D) 2
