p is a transversal to lines a and b. One pair of co interior angles is ( 54ᵒ, 126ᵒ). Are the lines a and b parallel?
Answer:
Lines a and b are parallel.
Because when 54 is added to 126, the answer is 180.

Kara earned $136.75 last week working 16 hours. She earned $10.50 per hour at the fast food restaurant and $4.25 per hour helping her aunt clean her store. how many hours did she work at the fast food restaurant ? how many hours did she help her aunt clean the store ?
Answer:
ANSWER: she worked 11 hours at the fast food restaurant and 5 hours helping her aunt
Step-by-step explanation:
First we are going to try to find how many hours she worked on the fast food restaurant so you multiply 4.25 time 16 and x
10.50x + 4.25(16-x) =136.75
10.50x + 68 - 4.25x= 136.75
Then, you subtract 68 from both sides and subtract 4.25x from 10.50x
6.25x=68.75
Divide
X=11 that is how many hours she worked at the FAST FOOD RESTAURANT
Then 16-11 and that gives us how many hours she helped her aunt.

Use I = PRT to solve.
(time is in years)
P = $450
R = 5%
T = 7 years
Find I.
Answer:
$150.50
Step-by-step explanation:
I = 450 × 0.05 × 7 = 157.5
I = $ 157.50
The simple interest accumulated
on a principal of $ 450.00
at a rate of 5% per year
for 7 years is $ 157.50.
Hellooo :)
The answer is I = $ 157.50

Step-by-step explanation:
There are 92,746 seats available for fans at UGA's Sanford Stadium. Auburn University's Jordan-Hare Stadium has seating for 87,451 for fans. How many more seats are there at UGA's stadium?
Given :
Number of seats at UGA's Sanford Stadium, [tex]n_1 = 92,746[/tex] .
Number of seats at Auburn University's Jordan-Hare Stadium, [tex]n_2=87,451[/tex] .
To Find :
How many more seats are there at UGA's stadium.
Solution :
Extra seats at UGA's stadium = seats at UGA's Sanford Stadium - seats at
Auburn University's Jordan-Hare Stadium
= 92,746 - 87,451
= 5295
Hence, this is the required solution.

17.)True or false: Sequences of rigid motions can be applied to any type of polygon.
a)This statement is false. Sequences of rigid motions can only be applied to polygons with fewer than 10 vertices.
b)This statement is false. Sequences of rigid motions can only be applied to convex polygons.
c)This statement is true.
d)This statement is false. No more than one rigid motion can be applied to any polygon.
18.) True or false: A sequence of rigid motions that maps a pre-image to an image must contain no fewer than two unique rigid motions for the pre-image and the image to be congruent.
a) This statement is false. If a sequence of rigid motions maps a pre-image to an image, the pre-image and the image are congruent no matter the details of the sequence of rigid motions.
b)This statement is true.
c) This statement is false. A sequence of rigid motions that maps a pre-image to an image must contain no more than two unique rigid motions for the pre-image and the image to be congruent.
d) This statement is false. A sequence of rigid motions that maps a pre-image to an image must contain exactly two unique rigid motions for the pre-image and the image to be congruent.

18.) a) This statement is false. If a sequence of rigid motions maps a pre-image to an image, the pre-image and the image are congruent no matter the details of the sequence of rigid motions
Step-by-step explanation:
1) b) 5 A translation is a form of rigid transformation that preserves the shape and dimensions of the pre-image in the image
3) a) D. The letter D has an horizontal line of symmetry
4) b) B'. The reflection of an object about a line is as far behind the mirror as the object is in front
5.) a) The arrow will point in the southwest direction
6.) 88°. A 272° rotation clockwise, is equivalent to a 360° - 272° rotation. anticlockwise
9) 2,160°.
One rotation = 360°, 6 rotations = 6 × 360° = 2,160°
10.) d) The number of sides is even
The existence of a line symmetry gives equal number of sides on both sided of the line of symmetry, which gives an even an even number of sides
15.) a) Reflecting about the y-axis and then rotating 90° counterclockwise
Reflecting across the line y = -x, gives (x, y) → (-y, -x)
Reflecting about the y axis gives, (x, y) → (x, -y))
Rotation 90° counterclockwise gives (x, -y) → (-y, -x)
16) b) (0, 0),
Reflection about the line y = x gives (x, y) → (y, x)
Reflection about the line y = -x gives (x, y) → (-y, -x)
When, (x, y) = (0, 0), (y, x) ≡ (-y, -x)
when
17.) c) This statement is true,
A rigid motion involves the equal change of all coordinates on the pre-image to form the image
18.) a) This statement is false. If a sequence of rigid motions maps a pre-image to an image, the pre-image and the image are congruent no matter the details of the sequence of rigid motions
The preimage and the image formed by a rigid transformation are always congruent

A farmer collected 1,957 eggs from her chickens she puts them into a carton that each hold 48 eggs how many cartons will the farmer need to hold all of the eggs
Answer:
41 cartons will be needed
Step-by-step explanation:
here, we need to know the number of cartons the farmer needs to hold all the eggs
To calculate this, we simply make a division of the number of eggs by the number of eggs in a carton
That would be 1957/48 = 40.77
The closest number of cartons here is 41

Community Gym charges a $50 membership fee and a $55 monthly fee. Workout Gym charges a $200 membership fee and a $45 monthly fee. After how many months will the total amount of money paid to both gyms be the same? What will that amount be?
What are you looking for?
Define a variable:
Write the equation:
Solve the equation:
What will the amount of money be when the total amount of money paid to both gyms is the same?
Answer:
Step-by-step explanation:
Community gym
=> membership fee = $50
=> monthly fee = $55
=> First month = 105$
=> 50 + 55(x)
=> 50 + 55 (15)
=> 50 + 825
=> 875
Workout gym
=> membership fee = $200
=> monthly fee = $45
=> First month = 245$
=> 200 + 45(x)
=> 200 + 45(15)
=> 200 + 675
=> 875
On the 15th month, community gym and workout gym will both get the same amount of $875.

The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 . The combined area of these three rooms is 189 square feet. What is the value of one box on the tape diagram ?
Answer:
The value of one box in the tape diagram will be 21 square feet
Step-by-step explanation:
Here, we have the total ratio added as 4 + 3 + 2 = 9
So the area of one box on the tape diagram will be the combined area divided by the total square feet
Mathematically, that will be;
189 square feet/9 = 21

Give your answer as an improper fraction in its simplest form.
Given: O ∈ AB , ON is ∠ bisector of ∠AOC, OF is ∠ bisector of ∠COB, m∠FOB=70°. Find: m∠AON
Answer:
AOC = 20 degrees
Step-by-step explanation:
We know that FOB is 70 degrees, and COF is 90 degrees. So just add 70+90 and get 160 degrees. Then you subtract that from AOB which is 20 degrees.
