AB || CD and AC is oblique ;
So : Angle ( BAC ) = Angle ( DCA )
_________________________________
∆ ABC - ∆ ACD :
(1) AB = CD
(2) Angle ( BAC ) = Angle ( DCA )
(3) AC = AC
So According to (1) , (2) , (3) :
∆ ABC =~ ∆ ACD

Gianna, Jada, and Brittney and a bunch of other friends had a horseshoe competition. Jada and Brittney were eliminated after two rounds because they were too busy texting but Gianna went onto round eight to win 47 pieces of gum. Later, she gave two to each of her friends. She only has 1 remaining. How many friends does she have?
Answers
Answer:
23 friends
Step-by-step explanation:
Let the number of friends she has = x
Total number of gum = 47 pieces
She gave 2 each to her friends, hence:
2x + 1 = 47
2x = 47 - 1
2x = 46
x = 46/2
x = 23
Therefore, the number of friends she has is 23

Answer:
The length will be multiplied by 2.
Step-by-step explanation:
By looking at the first and third ratio, we know that the no. of birck have been multiplied by 2 and the length has also been multiplied by 2 .
So when the number of bricks is multiplied by 2, the length is multiplied by 2
Answer:
2Step-by-step explanation:
Using the table we observe the points
(6, 3) and (12, 6)The number of bricks doubled
6*2 = 12, andThe length is doubled accordingly

Answer:
m∠RMS = 20°
Step-by-step explanation:
Find ∠RMS and look at the two values it crosses.
∠RMS crosses through 180 and 160.
Find the difference between the two values to get the measure:
180 - 160 = 20°
So, m∠RMS = 20°
(Its also an acute angle.)
Answer:
20
Step-by-step explanation:
The mistake is in using 160 as the answer. It isn't.
The angle is very small well under 90. It is acute.
The horizontal part of the angle is on 180 degrees of the protractor.
Therefore the angle size is 180 - 160 = 20 degrees.

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?
Answers
Answer:
$4.7Step-by-step explanation:
step one:
Let the cost be y
to solve for the cost of a movie ticket, we need to solve the expression
y=2.75+0.10x
step two:
given that x is the number of years between 1980-2000
the number of years is 20years
put x= 20 in the expression for the cost we have
y=2.75+0.10(20)
y=2.7+2
y=$4.7
You and your friend each purchase an equal number n of magazines. Your magazines cost $1.50 each and your friend's magazines cost $2 each. The total cost for you and your friend is $10.50. Write and solve an equation to find the number of magazines you purchased.
Answers
Given:
You and your friend each purchase an equal number n of magazines.
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Total cost = $10.50
To find:
The equation to find number of magazines you purchased.
Solution:
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Number of magazines purchased by you and your friend = n
Total cost = [tex]1.50n+2n[/tex]
It is given that total cost is $10.50.
[tex]1.50n+2n=10.50[/tex]
[tex]3.50n=10.50[/tex]
Divide both sides by 3.50.
[tex]n=\dfrac{10.50}{3.50}[/tex]
[tex]n=3[/tex]
Therefore, required equation is [tex]1.50n+2n=10.50[/tex] and the number of magazines purchased by you is 3.

In the figure, m<7 = 100. Find the measure of <9.
Answers
As < 7 and angle < 9 are alternate interior angles, their sum will be equal .
Which means :-
[tex] < \: 7 = < \: 9[/tex]
[tex] < 9 = 100°[/tex]
Therefore , the value of <9 is 100° .
The magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.
What are parallel lines?
Two or more lines that lie in the same plane, equidistant from each other and never intersect each other are known as parallel lines.
Given is ∠7 = 100°.
The lines u and t are parallel to each other. The alternate interior angles are equal in magnitude. From the figure it is clear that ∠7 and ∠9 are alternate interior angles. Therefore, we can say that ∠7 = ∠9 = 100°.
Therefore, the magnitude of ∠9 will be same as that of ∠7 which is equal to 100°.

Answers
Answer:
The answer is option CStep-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8, 10) and (-7, 14)
The slope is
[tex]m = \frac{14 - 10}{ - 7 - 8} = \frac{4}{ - 15} = - \frac{4}{15} \\ [/tex]
We have the final answer as
[tex] - \frac{4}{15} \\ [/tex]

6. m∠D = 118
7. m∠E = 43
8. m∠H = 85
Step-by-step explanation: complementary= 90 supplementary = 180
5. (2x - 8) + (4x +4) = 90
6x - 12 = 90
6x = 102
x = 17
m∠A = 2x - 8
m∠A = 2(17) - 8 = 26
6. (2x + 18) + (5x + 8) = 180
7x + 26 = 180
7x = 154
x = 22
m∠D = 5x + 8
m∠D = 5(22) + 8 = 118
7. (2x + 15) + (3x + 5) = 90
5x + 20 = 90
5x = 70
x = 14
m∠E = 2x + 15
m∠E = 2(14) + 15 = 43
8. (5x - 20) + (4x + 7 ) = 180

h-(-2.22)=-7.851 solve for h
Answers
Answer:
[tex]\boxed {h = -10.071}[/tex]
Step-by-step explanation:
Solve for the value of [tex]h[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
The opposite of [tex]-2.22[/tex] would be [tex]2.22[/tex]:
[tex]h - (-2.22) = -7.851[/tex]
[tex]h + 2.22 = -7.851[/tex]
-Subtract both side by [tex]2.22[/tex]:
[tex]h + 2.22 - 2.22 = -7.851 - 2.22[/tex]
[tex]\boxed {h = -10.071}[/tex]
So, the value of [tex]h[/tex] is [tex]-10.071[/tex].
