At a college, 7 out of every 10 students worked either a full-time or part-time job in addition to their studies. If 4,900 students were enrolled at the college, how many students did not have a full-time or part-time job?
Remark
If 7/10 do have full or part time jobs then 3/10 do not.
That comes from 1 which represents all the students subtract 7/10 to get 3/10
Solution
Those without jobs = 4900 * 3/10 = 4900 *0.3 = 1470 that do not have any kind of job.

y [25, 100] is the range of the population of Blue Whales off the coast of Antarctica from months 5 to 10.
Therefore, the correct answer is:
C. y [25, 100]
Here,
To find the range of the population of Blue Whales off the coast of Antarctica from months 5 to 10,
we need to determine the minimum and maximum values of the population during this period based on the graph.
From the graph, we can see that the population values are between approximately 25 and 100 (inclusive) during months 5 to 10.
The square brackets [ ] denote that the endpoints are included in the range.
so, we get,
y [25, 100] is the range of the population of Blue Whales off the coast of Antarctica from months 5 to 10.
Therefore, the correct answer is:
C. y [25, 100]

A rectangular field is 300 meters long and 250 meters wide. What is the area of the field in square kilometers
The area of the field is obtained by multiplying length by width resulting 75,000 square meters. Converting this to square kilometers by dividing by 1,000,000 gives the area in square kilometers as 0.075 km².
Explanation:To calculate the area of the rectangular field, we multiply the length by the width. Given that the length is 300 meters and the width is 250 meters, the area in square meters would be 300 meters * 250 meters = 75,000 square meters.
Keep in mind that 1 square kilometer (km²) is equivalent to 1,000,000 square meters (m²). So, to convert the area from square meters to square kilometers, we divide the area in square meters by 1,000,000. Therefore, the area of the field in square kilometers is 75,000 m² / 1,000,000 = 0.075 km².

If the length of the printed photograph is 5 inches, what should the width be?
3 inches 4 inches 6 inches 7 inches 8 inches
The ratio is 4:5
because 8 divided by 2 is 4

On six books shelves there are 72 books per shelf.How many books are there altogether? If 1/3 of these are non-fiction how many fictional books are there?
Given:
Total shelves: 6
Books per shelve: 72
Total books = ?
Solution:
Total books: 6 * 72 = 432
Total books = 432
Part 2:Given:
Fiction books = 1/3 of total books
Solution:
Nonfiction books = Total books - 1/3 of total books
= 432 - 1/3 * 432
= 432 - 166 = 266
Non- fiction books = 266
7. Lakeisha is designing a rectangular sunroom. She wants the room to be 14 feet wide and have a perimeter that is greater than 108 feet. Select all of the possible lengths of lakeisha’s sunroom. A. 14 feet b. 27 feet c. 40 feet d. 54 feet e. 60 feet
We are required to find all the possible length of lakeisha’s sunroom
The possible length of the rectangle are length greater than 40 which are 54 feet and 60 feet
perimeter of a rectangle = 2(length + width)
perimeter > 108 feet
Width of the sunroom = 14 feet
The inequality:
2(x + 14) > 108
2x + 28 > 108
2x > 108 - 28
2x > 80
divide both sides by 2
x > 80 / 2
x > 40 feet
Therefore, the possible length of the rectangle are length greater than 40 which are 54 feet and 60 feet

The blueprint for landscaping a yard has a scale of 1/2" to 1 foot. If the bloeprint is a rectangle 18inches by 22 inches, what are the dimensions of the yard
Answer:
36x44 feet are the dimensions of the yard.
Step-by-step explanation:
Given that the blueprint for landscaping a yard has a scale of 1/2" to 1 foot.
i.e. scaling factor is 1/2 for one foot.
If real dimension is 1 foot, it is shown as 1/2 inch in blue print.
Using this we can find the real dimensions if given blue print dimensions.
The blueprint is a rectangle 18inches by 22 inches,
Hence real length of rectangle = 18(2) feet = 36 feet
Width of rectangle = 22(2) = 44 feet
i.e. the yard has dimensions as 36x44 feet.

What is a correct congruence statement for the triangles shown?
Enter your answer in the box.
△ ______≅△NKW
For this one, look at the symbols inside each angle. In math, the rounded edges inside of angles mean they are congruent. So find which ones have the same amount of rounded edges and that would be your answer.
NKW ≅ UZE
put the corresponding angles in the middle. Since the object you were comparing to had the one line as the middle point, then that is your middle as well.
Hope this helps! Comment with any questions you may have.
Answer:
[tex]\Delta UZE\cong \Delta NKW[/tex]
Step-by-step explanation:
We have been given a graph of two triangles and we are asked to find the correct congruence statement for our given triangles.
We can see in triangle NKW and triangle UZE.
[tex]EZ\cong WK[/tex],
[tex]\angle ZEU\cong \angle KWN[/tex],
[tex]\angle UZE\cong \angle NKW[/tex].
Since two angles and included side of triangle NKW is congruent to two angles and their included side of triangle UZE, therefore, [tex]\Delta UZE\cong \Delta NKW[/tex] by Angle-Side-Angle congruence theorem.

Which statement is true?
A. There is a weak positive association between the variables.
B. There is a weak negative association between the variables.
C. There is a strong positive association between the variables.
D. There is a strong negative association between the variables.
the answer is d (i think) because anything aboveboard .90, whether it is positive or negative
Answer: D. There is a strong negative association between the variables.
Step-by-step explanation:
We know that when the value of the correlation coefficient lies between -1 to -.05 , then we say there is strong negative correlation between the variables.
OR
When the value of the correlation coefficient lies between 0.5 to 1, then we say there is strong positive correlation between the variables.
Given : In one study, it was found that the correlation coefficient between two variables is -0.93.
∵ -1< -0.93 <-0.5
Then , it indicates that there is a strong negative association between the variables.

4. The translation is considered an isometry or rigid motion. The figure's size, shape, area, etc has not changed. The only thing that changed is its position.
5. The rule stated means you shift the point 3 units to the right and 4 units up.
6. The rule would be (x,y) ---> (x-1, y-3) so we effectively subtract 1 from the x coordinate; subtract 3 from the y coordinate
7. Add 2 to the x coordinate to get x+2 = 2+2 = 4. Subtract 1 from they coordinate and we have 5-1 = 4. The point ends up at (4,4). Check out the attached image below.

Julia has 2 identical rooms in her house. If each room measures 8 feet on one side and 12 feet on another, what is the total area of the rooms?
Answer
192 ft²
Explanation
The rooms measures 12 feet by 8 feet. So it is a rectangle.
The area of a rectangle = length × width
= 12 × 8
= 96 ft²
The area of one room is 96 ft². There are 2 similar rooms.
The area of the 2 rooms = 96 × 2
= 192 ft²
Simplify. (h + 12) + (p +24) a) hp + 288 b) hp + 36 c) 12h + 24p d) h + p + 36
(h+12) + (p+24)
h+p+12+24 = h+p+36
