Which congruence theorems can be used to prove AABR = AACR? Select three options.
A. HL
B. AS
C. SSS
D. ASA
E. AAS
Answer:
HL, SAS, ans SSS
Step-by-step explanation:
ASA and AAS cannot be used because we can only confirm one angle of each triangle.
Congruent shapes have equal corresponding sides and angles.
The congruence theorems that can be used to prove [tex]\triangle ABR \cong \triangle ACR[/tex] are HL, SAS, and SSS
[tex]\triangle ABR \cong \triangle ACR[/tex] means that, the triangles are congruent.
From the attached figure, we have the following congruent sides and angle:
AB and AC --- SideBR and CR --- SideAR and AR --- Side (Hypotenuse Leg)Angle C and Angle B --- angleThe above highlights mean that the following theorems can be used to prove that the triangles are congruent:

Rearrange the equation
a = 1/2 (b-c)
to make b the subject.
Answer:
b = 2a + c
Step-by-step explanation:
Given
a = [tex]\frac{1}{2}[/tex] (b - c)
Multiply both sides by 2 to clear the fraction
2a = b - c ( add c to both sides )
2a + c = b
After the rearrangement, the equation as b the subject b = 2a + c.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given that the equation;
a = 1/2 ( b - c)
Rearranging the equation;
a = 1/2 ( b - c)
Multiplying 1/2 to the the terms of brackets,
a = (b/2) - (c/2)
b/2 = a + (c/2)
Divide by 2 on both sides of the equation;
b = 2a + c
Therefore, the equation as b the subject b = 2a + c.

Which of the following tables represents a proportional relationship?
Answer:
C
Step-by-step explanation:
A is incorrect because as x goes from 0 to 1, y jumped from 0 to 4
B is incorrect because as x goes up by 2, y at first goes up by 2 but then jumped to 4.
C is correct because as x goes up by 1, y goes up by 3

An 8-ounce cup of gourmet coffee costs $4.50.If the price remains the same how much would 3 quarts cost
Answer:
$54
Step-by-step explanation:
1 quart = 32 fl oz
3 quarts would contain 32 x 3 = 96 quarts
1 ounce would cost : $4.50 / 8 = $0.5625
96 quarts would cost = 96 x $0.5625 = $54
In a standard deck of cards, what is the probability of drawing a face card?
Answer (round) to the hundredth place value.
Reasoning:
There are 12 face cards since there are 3 face cards in any suit, and 4 suits. So 3*4 = 12.
There are 52 cards total.
Dividing the values leads to 12/52 = 0.230769 which rounds to 0.23

Answer:

Step-by-step explanation:
always remember to square root if not answer will be counted as incomplete or incorrect!
Answer:
1) response b
2) x=35 (response c)
3) response d
Step-by-step explanation:
1) The Pythagorean theorem's "C" value is the value of your hypothenuse, which means that it would be c^2-b^2=a^2
You would set it up as "7^2-4^2", and then to get rid of the squared value, you would have to square root it
2) In this question, you're finding the hypothenuse, therefore the two values given are your "a" and "b" values.
[tex]\sqrt{21^{2} +28^{2} } =x[/tex]
[tex]\sqrt{441+784}=x[/tex]
[tex]\sqrt{1225} =x[/tex]
x=35
3) This is pretty much self explanatory if you know the C value is the hypotenuse
[tex]\sqrt{4^{2}+5^{2} }[/tex]
[tex]\sqrt{16+25}[/tex]
[tex]\sqrt{41}[/tex]

There are 15 books on a shelf. 8 of these books are new. The rest of them are used.
(a) What is the ratio of used books to all books on the shelf?
(b) What is the ratio of new books to used books?
Answer:
a. 7:15
b. 8:7
Step-by-step explanation:
there are 7 used books and 8 new books, thus, there are 15 books on a shelf.
(a) The ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex].
(b)The ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].
Given that:
Total number of books = 15
Total number of new books = 8
Total number of used books= 15-8
= 7
(a) The ratio of used books to all books on the shelf is calculated as:
Ratio = [tex]\dfrac{ Used \ books}{ Total \ books}[/tex]
= [tex]\dfrac{7}{15}[/tex]
(b) The ratio of new books to used books is calculated as:
Ratio = [tex]\dfrac{ New \ books}{ Used \ books}[/tex]
= [tex]\dfrac{8}{7}[/tex]
Thus, the ratio of used books to all books on the shelf is [tex]\dfrac{7}{15}[/tex] and the ratio of new books to used books is [tex]\dfrac{8}{7}[/tex].

what is 10 + 6x + 2x = 18
Answer:
X = 1
Step-by-step explanation:
combine 6x and 2x to make 8x
10 + 8x = 18
subtract 10 from both sides
8x = 8
divide both sides by 8
X = 1
6x-3=5x-5
can someone help me
Answer:
x=-2
Step-by-step explanation:
To find the value of x you will have to isolate the x.
6x-3=5x-5 ------> Add 3 to both sides to get rid of the 3
6x=5x-2 ------> Subtract 5x to both sides to get rid of the 5x
1x=-2
1x is the same as x so
x=-2
