Answer:
The correct options are;
1. Definition of supplementary angles
2. m∠1 + m∠2 = m∠1 + m∠3
3. m∠2 = m∠3
4. Definition of Congruent Angles
Step-by-step explanation:
The two column proof is presented as follows;
Statement [tex]{}[/tex] Reason
1. ∠1 and ∠2 are supplementary [tex]{}[/tex] Given
[tex]{}[/tex] ∠1 and ∠3 are supplementary
2. m∠1 + m∠2 = 180° [tex]{}[/tex] Definition of supplementary angles
[tex]{}[/tex] m∠1 + m∠3 = 180°
3. m∠1 + m∠2 = m∠1 + m∠3 [tex]{}[/tex] Transitive Property
4. m∠2 = m∠3 [tex]{}[/tex] Subtraction Property of Equality
5. ∠2 ≅ ∠3 [tex]{}[/tex] Definition of Congruent Angles
Given that angles ∠1 and ∠2 are supplementary angles and angles ∠1 and ∠3 are are also supplementary angles, then the sums of m∠1 + m∠2 and m∠1 + m∠3 are equal, therefore, ∠2 and ∠3 have equal quantitative value and therefore ∠2 = ∠3 and by definition, ∠2 ≅ ∠3.

James’s little brother and sister wanted to get a face paint. There were 5 kids in front, each kid takes 15 minutes to get their face painted. How many minutes do they have to wait after 3 kids?
Answers
Answer:
9 minutes
Step-by-step explanation:
As it states in the question it takes 15 minutes to paint 5 kids so you do 15/5=3
So it takes 3 minutes to paint each kid.
In the problem it asks how long does it take to paint three kids.
So now we do 3 minutes*3 kids=9 minutes
So it takes 9 minutes to paint three kids

HURRY PLEASE!!! Which generic rectangle would be used to factor x^2+7x+6
Answers
Answer:
Rectangle B
Step-by-step explanation:
Given the expression x^2+7x+6, to get the required rectangle we need to factorize first;
= x^2+7x+6
= x^2+6x+x+6
= x(x+6) + 1 (x+6)
= (x+1)(x+6)
From line 2 we will see that the terms contains x², 6x, x and 6. The rectangle that contains all this terms is rectangle B. Hence option B is correct.

Answer:
B
Step-by-step explanation:
SSS stand for Side Side Side, so the truangle must identify all it's sides. To identify sides it uses lines through the side like in B where 1 side has 1 line, 1 side has 2 lines, and the other side has 3 lines. That is the side identifiers, and because each side in B matches with 1 side in A, means that A and B are congruent because they have the same sides, so SSS.

Rachel's biscuits require 0.75 cup of milk for 1 batch. Use dimensional analysis to convert this amount into liters. Use the conversion factors 1 cup/0.5 pints to convert cups into pints, 1 pint/0.5 quart to convert pintos to quarts, and 1 quart/0.94 liter to convert quarts to liters. Use the correct number of significant digits to give your answer
Answers
Answer:
0.75 cup = 0.1763 liters
Step-by-step explanation:
From the question:
Using the conversion factors given in question
We are converting
0.75 cup to liters
Step 1
Convert cups to pint
1 cup = 0.5 pints
0.75 cup = x pints
x = 0.75 × 0.5 pints
x = 0.375 pints
Step 2
Convert pints to Quart
1 pints = 0.5 quart
0.375 pint = x quart
Cross Multiply
x quart = 0.375 × 0.5 quart
x quart = 0.1875 quart
Step 3
Convert from quart
1 quart = 0.94 liter
0.1875 quart = x liter
Cross Multiply
x liter = 0.1875 × 0.94 liter
x liter = 0.17625 liters
Approximately to 4 significant figures= 0.75 cup = 0.1763 liters
Answer:
0.75 cup = 0.1763 liters
Mae Ling earns a weekly salary of $390 plus a 8.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,300 worth of merchandise?
Answers
Answer:
She would make $734 in a work week if she sold $4,300 worth of merchandise.
Step-by-step explanation:
First, you should calculate the amount she would receive on comissions by multiplying the amount she sold for 8%:
$4,300*8%=$344
Now, you have to add the weekly salary plus the amount she receives for the comission on sales:
$390+$344=$734
According to this, the answer is that she would make $734 in a work week if she sold $4,300 worth of merchandise.

Robert needs to know if the triangle shown is a right triangle. Which equation could he use to help? A. 36+ 25= 49B. 25 + 36 = 49 C. 25 2 + 36 2 = 49 2 D. 36 2 –25 2 = 49 2
Answers
Answer:
C. 25² + 36² = 49²
Step-by-step explanation:
We use the Pythagoras theorem to determine if the triangle is a right angle triangle. The theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In geometry, hypotenuse is the longest side in a right angle triangle. This means it would have the highest number.
A. 36+ 25= 49
This is wrong because the theorem deal with the sum of the squares of the other two sides.
B. 25 + 36 = 49
This is wrong because the theorem deal with the sum of the squares of the other two sides.
C. 25² + 36² = 49²
This is correct as it matches the theorem.
D. 36² –25² = 49²
This is wrong because the theorem deal with the sum of the squares of the other two sides and not their difference.
