Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Probability of rolling an even number P(A):

[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Probability of flipping tails P(B):

[tex]\frac{1}{2}[/tex]

P(A OR B) = P(A) + P(B) – P(A AND B)

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) =  [tex]\frac{3}{4}[/tex]

1. 12 x 6 = 72 area of parallelogram: B x H (BH)

2. 15 + 23 = 38 x 10 = 380 divided by 2 = 190 area of trapezoid: (B1 + B2) x Height x 1/2 (basically dividing by 2)

3. 8 - 2 = 6 (b1) for the trapezoid, 6 (b1) + 8 (b2) = 14 x 4 (height) = 56 divided by 2 (multiplying 1/2) = 28. (Area of the triangle in the figure) 4 x 4 = 16 divided by 2 = 8. 28 + 8 = 36

Answer:

B and D

Step-by-step explanation:

If you count all of the dots, you see that the total amount of math books is 12.

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

Therefore, there are 2 out of the 12 books that weigh 2 1/8 pounds.

2/12 can also be simplified down to 1/6.

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
