Answer 2

Answer:

Answer:60

Step-by-step explanation:When you do 55+5 you get 60. That's because it moves 5 degrees right which adds onto 55. Then you do 180-60 to find the measure of 2. That's 120 and finally you do 180-120 to find the measure of 3, which is 60.

Two number cubes, each with the numbers 1 through 6, are rolled. What is the probability that the sum of the rolled numbers is 2?

Answers

Answer:

1/36

Step-by-step explanation:

The only way to get a sum of 2 with two dice is to roll 1s on both. there is one 1 on each dice, so you have a 1/6th chance for each. that gives you

1/6 × 1/6

which solves for your answer of

1/36

Please help! Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which statement describes the properties of triangles ABC and A''B''C'' after the transformations?A) ∠C and ∠C'' are congruent after both the translation and the dilation.
B) ∠C and ∠C'' are congruent after the dilation, but not after the translation.
C) segment AC and segment A double prime C double prime are congruent after both the translation and the dilation.
D) segment AC and segment A double prime C double prime are congruent after the dilation, but not after the translation.

Answers

Answer:

Step-by-step explanation:

1) Translated figures are congruent ones, so $\bigtriangleup ABC\cong \bigtriangleup A'B'C'$ , one unit to the right and one up in comparison to $\bigtriangleup ABC\cong \bigtriangleup ABC$ .

2)Since $\bigtriangleup A''B''C''$ was dilated with a scale factor of two then It's a similar figure to $\bigtriangleup ABC$ . Similar figures have congruent angles and different sizes.

Hence, ∠C≅∠C"

Jenna buys 12 lb of meat. Some of the meat is chicken and costs $1.90/lb. The rest is beef, which costs $4.30/lb. She spends a total of $34.80Which equation models this situation?
Let c represent the number of pounds of chicken she buys.
A. (1.9 + 4.3)(12 – c) = 34.8
B. 4.3c + 1.9(c + 14) = 34.8
C. 4.3c + 1.9(12) = 34.8
D. 1.9c + 4.3(12 − c) = 34.8

Answers

The answer of this question is c

4.30c+1.90 (12)=$34.80

Please help fast this is for my sister and I don't understand (30 points)

Answers

Answer:

I don’t get most of it, but I believe “doubles” means two of the same number added together. For example, 9+9 is a double. I think “doubles +1” means a double and add one. For example, 6+6+1. If I were your sister, I would write “9+9 = 18” for doubles and “6+6+1 = 13” for doubles +1.

I hope I helped!
