Which congruence theorems can be used to prove AABR = AACR? Select three options.
A. HL
B. AS
C. SSS
D. ASA
E. AAS
Answers
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:

Answer:
(-5,-7)
Step-by-step explanation:
To find points of intersection, first set the two equations equal and then solve for x. Then substitute that x back into either equation for the complete point of intersection.
2x + 3 = -4x - 27
6x = -30
x = -5

Answer:
x = 80y = 122Step-by-step explanation:
The angles marked with x-expressions are complementary, so ...
(3/4x -2) + (2/5x) = 90
x(3/4+2/5) = 92 . . . . . . . add 2
x(23/20) = 92 . . . . . . . . combine the fractions
x = 92(20/23) . . . . . . . . multiply by 20/23
x = 80
__
The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...
y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32
y = 122

His total hours he worked is;
21
Step-by-step explanation:
The of hours between 9:00 A.M. and 4:30 P.M. are;
[tex]\begin{array}{ccc}From \ 9:00 \, A.M. & to \ 10:00\, A.M. & = 1 \, Hour\\From \ 10:00 \, A.M. & to \ 11:00\, A.M. & = 1 \, Hour\\From \ 11:00 \, A.M. & to \ 12:00 \, P.M. & = 1 \, Hour\\From \ 12:00 \, P.M. & to \ 1:00 \, P.M. & = 1 \,Hour\\From \ 1:00 \, P.M. & to \ 2:00 \, P.M. & = 1 \,Hour\\From \ 2:00 \, P.M. & to \ 3:00 \, P.M. & = 1 \,Hour\\From \ 3:00 \, P.M. & to \ 4:00 \, P.M. & = 1 \,Hour\\From \ 4:00 \, P.M. & to \ 4:30 \, P.M. & = 0.5 \, Hour \end{array}[/tex]
Sum of the hours Harold Crispen spends at the workplace on a workday = (1 + 1 + 1 + 1 + 1 + 1 + 1 + 0.5) hours = 7.5 hours
The time Harold Crispen take for launch each workday = 0.5 hour
The number of hours Harold Crispen spend working each day = (7.5 - 0.5) hour
The number of hours Harold Crispen spend working each day = 7.0 hours/day
The number of days he worked = Monday + Tuesday + Thursday = 3 days
The total hours he worked = (The number of hours he works each day) × (The number of days he worked)
His total hours he worked = 7.0 hours/day × 3 days = 21.0 hours.

_________
2/3
EXPLANTION:

To find the slope the equation is
y2 minus y1 / x2 minus x1
Next you have to pick two points, the points I picked are (4,2) and (7,4)
y2 = 4
y1 = 2
x2 = 7
x1 = 4
4 - 2 / 7 - 4
The final answer would be 2/3 :)

The cost for 25 square yards of carpet is $650 including delivery and installation. The cost for 40 square yards of installed carpet is $950. Write an equation in slope-intercept form (y = mx + b) for the cost of the installed carpet
Answers
Answer:
The equation is;
y = 20x + 150
Step-by-step explanation:
Firstly, let us identify the coordinates
(area, cost of area)
We start by getting the points;
(25,650) and (40,950)
The slope will be;
m = (y2-y2)/(x2-x1)
m = (950-650)/(40-25)
m = 300/15 = 20
So the partial equation is;
y = 20x + c
To get the value of c which is the y-intercept, we make use of any of the two points
650 = 20(25) + c
650 = 500 + c
c = 650-500
c = 150

consider the steps for determining the quotient of 12/x-4 / 4/x-4
Answers
Answer:
Quotient = 3
Step-by-step explanation:
We need to solve the given expression :
[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}[/tex]
It can be done as follows :
As, [tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}=\dfrac{12}{x-4}\times \dfrac{x-4}{4}\\\\=\dfrac{12}{4}\\\\=3[/tex]
Hence, the required quotient is 3.

A handful of coins has the value of 1 dollar and 79 cents. There are three times as many dimes as quarters, and five more pennies than dimes. If there are only three types of coins, how many coins of each type are there?
Answers
Answer: There are 3 quarters , 9 dimes and 14 pennies.
Step-by-step explanation:
Let x= Number of quarters
Then, Number of dimes = 3x
Number of pennies = 3x+5
1 quarter = $ 0.25
1 dime = $0.10
1 penny = $ 0.01
So, Total amount = 0.25x+ 0.10(3x) + 0.01(3x+5)
= 0.25x+0.30x+ 0.03x+0.05
= 0.58x+0.05
Since Total amount = 1 dollar and 79 cents = $ 1.79 [1 cent = $ 0.01]
So,
[tex]0.58x+0.05=1.79\\\\\Rightarrow\ 0.58x= 1.74\\\\\Rightarrow x=\dfrac{1.74}{0.58}\\\\\Rightarrow x=3[/tex]
Thus, there are 3 quarters , 9 dimes , 14 pennies.

Answers
Answer:
down 2, right 1
Step-by-step explanation:
Here, we want to know what -2 means for the slope
The following conventions are necessary to be known;
down is negative
left is negative
up is positive
right is positive
Thus;
Since the slope is actually vertical change/ horizontal;
The 2 value must be in respect to the y-axis
Hence;
up 2 right 1 is positive
down 2 left 1 is positive since both are negatives
The correct answer is thus;
down 2, right 1
