ABCD is rotated counterclockwise about the origin. By how many degrees
was ABCD rotated?
O A. 360°
• B. 180°
• C. 270°
O D. 90°
Answers
Answer:
B. 180 degrees
Step-by-step explanation:
They are exactly across from one another. Here, this will make more sense.
0 (starting point)

180 (where you ended up)
Now till the screen towards the right. The zero and the 180 should be pointing in the same direction as the squares.
Degrees was ABCD rotated or transformed to form A'B'C'D' is 180 degrees about the origin .
What is rotation in graph?In geometry, a transformation is an operation that moves, flips, or changes a shape to create a new shape. A rotation is an example of a transformation where a figure is rotated about a specific point (called the center of rotation), a certain number of degrees.
According to the question
ABCD is rotated counterclockwise about the origin.
Degrees was ABCD transformed to form A'B'C'D' is
180 degrees about the origin
As when we rotate a figure of 180 degrees about the origin either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) and graph the rotated figure.
So, as per figure ABCD which is in first quadrant were x and y both are positive and figure A'B'C'D' third quadrant were x and y both are negative.
Hence, Degrees was ABCD rotated or transformed to form A'B'C'D' is 180 degrees about the origin .

The measure of an angle is 87°. What is the measure of its supplementary angle?
Answers
Answer:
180-87 = 93
Step-by-step explanation:
supplementary angles add up to 180°
so (the other angle + 87)=180°
other angle =180-87=93°
Answer:
93 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Therefore, the equation for finding the supplementary angle to 87 would be:
[tex]87 + x = 180\\x=180-87\\x=93[/tex]

That said, he did give me his word that he’d deliver this letter to you. He says he owes me for the time I doubled back to save him.
I’m sorry about that. I never would have imagined myself choosing those two over you.

Point W is on line segment V X. Given VX = 18 and VW = 14 determine the length W X
Answers
Answer: WX = 4
Concept:
Here, we need to know the idea of segment addition postulate.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
Given information
VX = 18
VW = 14
Given expression deducted from the segment addition postulate
WX = VX - VW
Substitute values into the expression

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $77. A season ski pass costs $450. The skier would have to rent skis with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answers
Answer:
5
Step-by-step explanation:
Given:
Daily pass = $77Season ski pass = $450Skis = 2077 + 20 = 97
450 + 20 = 470
Keep multiplying 97 with random numbers until it passes 470.
97 × 4 = 388
97 × 5 = 485
So, the skier will have to pay daily passes 5 times to be more expensive than the season pass.

1.Write the linear equation that models the equation?
2.What is the cost per T-shirt?
3.What is the standard shipping and handling bag?
Answers
Step-by-step explanation:
Citydog Screen Printers received two orders for a t-shirt designed for a math symposium. The first order was for 40 shirts at a total cost of $295 and the second order was for an additional 80 shirts at a total cost of $565. Each order included a shipping and handling charge.
Then we have to writer a linear equation, for which I got: y-27/4x+25. We also had to find the cost per t-shirt, for which I got: $31.75. The last part I don't understand, however: fidn the shipping and handling charge.
The second word problem is:
It costs Consolidated Cereals Corporation $1050 to produce 100 boxes of corn flakes and $1250 to produce 500 boxes. I found the cost function: c(x)=1/2x+1000 but don't know how to determine the fixed cost and the variable cost per box (mainly because I have no idea what those are.)
Cost= m x+b
x is the cost per shirt, b is the handling charge
295=40m+b
565=80m+b
subtract the first equation from the second:
370=40x solve for m, the cost of each shirt. Then solve for b, put all that into y= mx+b
One the second question,
Cost= variable cost * n + Fixedcosts or
cost= n*v+F
1250=500v+f
1050=100v+f
subtract the second equation from the first
200=400v solve for v, and it is 1/2 dollar. Solve for f, the fixed cost, and it looks as if it is 1000 dollars.

Restaurant Two had the fastest service.

I divided the time it took – for example – 48 divided by 6. I would do this because I wanted to find out each person took (6 people), and the amount of time it took for each person to get their food. I would use division for this problem because I am finding how much each person took out of the whole time.
Answer
The 2nd restaurant is the fastest
Step-by-step explanation:
I. Compare Time per Customers
When 1st restuarant = 48/6 = 9
2nd restuarant = 42/7 = 6
3rd restuarant = 63/9 = 7
Given if in 1 min, I can serve 20 customers = 1/20 = 0.05
in 1 min, He can serve 10 customers = 1/10 = 0.1
See the different? I can serve better than him.
So The answer is the 2nd restuarant.
