Answer:
The resultant segments are parallel
I also need help on this for a good grade!
Answer:
2 units left2 units downreflection across the y-axisStep-by-step explanation:
The letters designating the original figure, RSTU, start at the bottom of the figure and proceed clockwise around it. The letters designating the image, R'S'T'U' start at the bottom and proceed counterclockwise around it. This tells you ...
the figure has been reflected once (CW-CCW order is reversed)the line of reflection is a vertical line (up-down orientation hasn't changed)__
The fill-in for the answer tells you that translation takes place before reflection. To figure out how much translation is needed, you need to know the line of reflection.
Line of ReflectionYou can look at the reflection choices to see where the line of reflection is. We're guessing that the only vertical line choice is the y-axis. (If the line of reflection is x=1, there doesn't need to be any horizontal translation.) If the image is reflected across the y-axis, the point R' moves from (-3, 0) to (3, 0). This is where R' is reflected from.
TranslationThe point R is at (5, 2). To move R from (5, 2) to (3, 0) prior to reflection, the x-coordinate needs to decrease by 2 (from 5 to 3), and the y-coordinate also needs to decrease by 2 (from 3 to 0). That is, the point R must be translated left 2 and down 2 to get it to (3, 0).
__
R'S'T'U' is the image of RSTU after translation 2 left, 2 down, and reflection across the y-axis.

Find the mean of the data in the bar chart below.
Answer:
9/2≈4.5
Step-by-step explanation:
mean is 4, 5,6,3
Find the mean of the list:
(4, 5, 6, 3)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 4 + 5 + 6 + 3:
(4 + 5 + 6 + 3)/(number of elements)
Counting, we see that the list has 4 elements:
(4 + 5 + 6 + 3)/4
4 + 5 + 6 + 3 = 18:
18/4
18/4 = 9/2:
Answer: 9/2≈4.5
The probability of rolling two number cubes whose numbers match is 6/36.
What is the probability of rolling at least 1 five?
Answer:
1/6
Step-by-step explanation:
if the chance is 6/36 for the first then the answer would be 1 in 6 to at least get a 5
Based on the probability of the number match, the probability of rolling at least 1 five is 1/6.
What is probability?Probability is the possibility of an event happening or not.
It is also described as the chance or likelihood of an event happening or not.
In a cube, there are six faces numbered 1 to 6
The probability of rolling two number cubes whose numbers match is 6/36.
Then 5 is a number our of the six numbers.
Therefore, the probability of rolling at least 1 five is 6/36 or 1/6.

1. The media reported that Olympic gold medalist Michael Phelps regularly consumed at least 8,000 calories per day when he was training for the Olympics. In order to do this, he ate at least three extra-large meals and also consumed a maximum of 2,000 calories worth of special energy drinks each day.
a.Write and graph an inequality to represent the number of calories from energy drinks Michael Phelps drank per day while training
b.Write and graph an inequality to represent the total number of calories Michael Phelps consumed each day.
2. Write a situation about Michael Phelps in which the inequality 3m + 2,000 ≥ 8,000 would represent the situation.
3. To keep from losing weight while training, athletes must not burn more calories than they consume in a day. On one day, Michael Phelps burned 1,000 calories per hour while swimming and an additional 3,000 calories while out of the pool. Write and solve an inequality to estimate the number of hours he swam that day if his daily average caloric intake was at most 9,000 calories.
4. An athlete wants to maintain a net caloric intake of no more than 2,000 calories for the day.
a. Write and solve an inequality to determine how many hours she must train if she burns an average of 750 calories per hour and eats a total of 8,000 calories.
b. Graph the solution to your inequality on a number line. Explain why your answer to part a is a solution to this situation.
c. If she trains 8 hours per day, what is the greatest caloric intake she can have to keep from losing weight? Explain your reasoning.

Rory covers her boat with a square plastic tarp. The tarp has an area of 900 square feet. What is the length of a side of the tarp in feet?
27
30
35
15
Answer:
30 ft
Step-by-step explanation:
Since Rory's plastic tarp is a square, then that means that the side lengths are equal, so the answer must be square root of 900, which is 30!

This year, Ms. Makratzaki’s small hardware store had sales of $536,000. Five years ago, the store had $441,000 in sales, and last year it had $517,000 in sales. Assuming a constant rate of increase, predict the amount of sales the store will have after 8 years.
a.
$650,000
b.
$669,000
c.
$688,000
d.
$707,000
Please select the best answer from the choices provided
A
B
C
D
Thinking it as a propotional increase, find the unit rate of change.
values: (0, 536,000), (-5, 441,000), (-1, 517,000)
unit rate of change:
[tex]\sf \dfrac{y2-y1}{x2-x1}[/tex]
[tex]\dashrightarrow \sf \dfrac{536,000-441,000}{0-(-5)}[/tex]
[tex]\dashrightarrow \sf 19000[/tex]
Therefore, the sales increase by $19000 each year.
After 8 years the sale increasement:
$19000 * 8$152000Total sales amount:
current sales + increasement in sales$536,000 + $152000$688,000So, correct answer is : $688,000

Answer:
111-(9*12)=3.
Step-by-step explanation:
There are 111 ounces of orange paint, which is going to go into the other bottles. How many bottles? 9. However, because in life we have different sized bottles, it states each bottle takes 12 ounces. In order to find the amount of ounces needed to find all 9 bottles, we first multiply 9*12, which equals 108. Filling all the bottles with orange paint will take up 108 ounces of the orange paint. We do have enough, since we have 111 ounces, but we must find how many ounces we have now that we've used up 108, which can be done by subtraction. 111-108=3. We have 3 ounces left over.
Now we translate everything we did into a mathematical equation. First, we multiplied, and then we subtracted the product from 111. 111-(9*12), which equaled 3, so 111-(9*12)=3. The parentheses technically aren't necessary, because if this is solved according to PEMDAS (the order of operations), the multiplication will occur first anyway.
