Answer:
So estimate.
Really depends on what needs to be estimated, the answer or the overall equation.
So doing the real one first.
283/11 = 25 8/11
You can’t have “part” of a student so rounding this you can go up since 8 is more then half of 11
So 26 students
If you were to round the overall equation then you’d get
280 / 10 which is 28 students per class
So two options.

12. A triangle has side lengths of 13 inches and 35 inches. What are the possible sidelengths for the third side of the triangle? Is a side length of 4 feet possible? Why or why not?
Answer:
22 in < third side < 48 inches
48 inches is not a possible side length
Step-by-step explanation:
The triangle inequality allows the third side to range between the difference and the sum of the two given sides:
(35 -13) < s < (35 +13)
22 < s < 48 . . . . . . inches
A side length of 4 feet (48 inches) does not satisfy the triangle inequality.
_____
Additional comment
Some authors allow the "or equal to" case in the triangle inequality. When the sum of the shortest sides is equal to the longest side, the triangle looks like a line segment: it has an area of zero. Other authors prefer a strict inequality, so the triangle has non-zero area. That is the version we have used to answer this question. YMMV
Riley has 300 stamps. 20% are from Russia 18% are for Europe 38% are from Australia the rest are from North America. How many of his stamps are from North America
Answer: 135%
Step-by-step explanation: Given
Europe = 35%
Asia = 10%
Australia* = 20%
North America = ?
To find
Europe + Asia + Australia =
35% + 10% + 20% = 65%
Then the total subtracted from the given
200 - 65 = 135
Therefore,
North America = 135%
Confirm
To make sure that is the correct answer, add it all together.
35 + 10 + 20 + 135 = 200
Which means it is correct.
You load boxes onto an empty truck at a constant rate. After 3 hours, there are 100 boxes on the truck. How much longer do you work it you load a total of 120 boxes? You work hour(s) longer Justify your answer
Answer:
36 minutes
Step-by-step explanation:
100 boxes in 3 hours is a rate. It is how fast you are working in boxes per hour 100/3 boxesperhour.
But 3 doesn't go into 100 very neatly and its going to make all kinds of ugly fractions or decimals. But lets look at minutes. 3 hours is 3 × 60 minutes (bc there's 60 minutes in an hour) So you loaded 100 boxes in 180 minutes. That's 100/180 boxes per minute.
100/180 = 10/18
10/18 means 10 boxes in 18 minutes.
So times 2 on the top and the bottom gives you 20/36.
20/36 means 20 boxes in 36 minutes.
This is your answer. It will take 36 minutes to load 20 more boxes.
I need help stuck on the last question
Answer:
5x + 4 = 14
Step-by-step explanation:
expand the brackets: 2 ((5x + 4)/2) = 5x + 4
and 7(2) = 7 x 2 = 14
⇒ 5x + 4 = 14
find the measure of angle A of the following triangle
Answer:
θ ≈ 48.2°
Step-by-step explanation:
The trig function that relates the angle, adjacent side, and hypotenuse is ...
Cos = Adjacent/Hypotenuse
This tells you ...
cos(θ) = 6/9
The angle is found from the cosine value using the inverse cosine function.
θ = arccos(6/9) ≈ 48.2°
Angle A is about 48.2°.
JOSHUA ORDERED A NEW PAIR OF NIKES ONLINE FOE $168 AND 2 HATS FOR $39 EACH HIS SHIPPING FEE IS 10% OF HIS TOTAL PURCHASE RICE HOW MUCH WILL JOSHUA PAY ALTOGETHER
Answer:
Joshua is paying a total of $270.60.
Step-by-step explanation:
Info that we have:
Pair of Nikes is $168.
2 hats for $78. (Not 39 because the question said $39 for each).
Shipping fee is 10% of total purchase.
We need to add up the cost.
168 + 78 = $246
Find how much is 10%.
10% of 246 = 24.6
Add the shipping fee to the total.
246 + 24.60 = 270.60
Answer:
Joshua is paying a total of $270.60.
Info that we have:
Pair of Nikes is $168.
2 hats for $78.
Shipping fee is 10% of total purchase.

Trisha had the following seven distances (in feet) in the triple jump.
29, 30, 28, 32, 28, 31, 27
What was the interquartile range of her distances?
1
2
5
3
Answer:
5 is your answer sweetheart
Step-by-step explanation:
We know that the range to a data set is the difference between the maximum data value and the minimum data value .
The given data set : 29, 30, 28, 32, 28, 31, 27
Maximum value = 32
Minimum value = 27
Then , the range the given data set would be :-
\begin{gathered}\text{Range = Maximum-Minimum}\\\\\Rightarrow\text{Range}=32-27=5\end{gathered}Range = Maximum-Minimum⇒Range=32−27=5
Hence, the range of her distances = 5

Rational Functions
In 1918, women were allowed to join the Marine Corps to handle the clerical duties, while the men fought in World War I. Prior to World War II, the United States Marine Corps Women’s Reserve was formed. Eventually Congress passed the Women’s Armed Services Integration Act. Women could then join the regular component of the Marine Corps, but the number of women could not exceed 2% of the total number of Marines.
By 1965, during the Vietnam War, there were 2700 women in the Marines. Women could participate in a wider variety of duties including radio operator, parachute rigger, quartermaster, auto mechanic, telegraph operator, and aerial gunnery instructor. But it was not until 1967 that a law was passed removing the restriction on the number of women in the Marines. In addition, women could be promoted to the rank of colonel. Within the next ten years, women would be able to work in all aspects of the Marine Corps except the infantry, artillery, armor, and the pilot/air crew.
In 2008, there were 9782 women in the Marine Corps on active duty, or about 5% of the Marines on active duty. Currently, women now receive combat training and are accepted into special skill schools that were traditionally only available to the male Marines. Also, women are working in non-traditional jobs and in certain other areas that were previously restricted. Women in the Marine Corps serve proudly and honorably next to their male counterparts in any area the United States Marine Corps requires. The number of women in the United States Marine Corps can be modeled by:
W = 414x^2 - 3341x + 9403 / 0.04x^2 - 0.32x + 1
where x is the number of years since 2000
Graph the model to find the number of women in the Marine Corps between 2000 and 2009.
Use your graph to estimate the number of female Marines in 2006.
Identify the x-intercepts of this function, if any.
Identify the vertical and horizontal asymptotes of the graph of this function, if any.
Use the function to estimate the number of women in the Marine Corps in 2015.
Give two reasons why the number of women in the Marine Corps could exceed your answer from Exercise 5.
Answer:
see attached for a graph2006: 8,194no x-interceptshorizontal asymptote: y = 10,350; no vertical asymptotes2015: 10,084no information on Exercise 5Step-by-step explanation:
a)The graph is attached
__
b)The value for 2006 is shown in the table for x=6: 8,194.
__
c)The graph does not cross y=0. It has a minimum of about 7392.
__
d)The denominator is never zero, so there are no vertical asymptotes. The horizontal asymptote is the ratio of the x^2 coefficients, 414/0.04 = 10,350.
__
e)The value of the function for x=15 is 10,084. The number of women in the Marines in 2015 is modeled as 10,084.
__
f)No information is provided regarding Exercise 5 or its answer.

What is the value of x?
Enter your answer in the box.
X=
Answer:
x = 5
Step-by-step explanation:
Looking at the ratios of height to base:
Smaller triangle 3x + 1 : 12
Larger triangle 4x : 3 + 12 = 4x : 15
Therefore as triangles are similar:
3x + 1 : 12 = 4x : 15
Write as fractions:
⇒ [tex]\dfrac{3x+1}{12}=\dfrac{4x}{15}[/tex]
Cross multiply and solve for x:
⇒ 15(3x + 1) = 12 · 4x
⇒ 45x + 15 = 48x
⇒ 15 = 3x
⇒ x = 5
Ratio remains same
[tex]\\ \tt\Rrightarrow \dfrac{3+12}{4x}=\dfrac{12}{3x+1}[/tex]
[tex]\\ \tt\Rrightarrow \dfrac{15}{4x}=\dfrac{12}{3x+1}[/tex]
[tex]\\ \tt\Rrightarrow 15(3x+1)=12(4x)[/tex]
[tex]\\ \tt\Rrightarrow 45x+15=48x[/tex]
[tex]\\ \tt\Rrightarrow 3x=15[/tex]
