Answer:
-1±√3,(1±4√2)/2, (2±3√2)/2,1±√3
Step-by-step explanation:
Simplify the roots, and simplify the fraction.
For example, for x=(-4±√48)/4, you can simplify √48 to be √16 * √3, which is just 4·√3 or 4√3. Now, the original fraction is (-4±4√3)/4, which can be simplified to -1±√3. Solve the other problems using the same method.

Miguel paid a total of $12,000 for stock that was $8 per share. If he sold all his shares for $15,000, how much profit on each share did he make? a. $2 b. $8 c. $10 d. $12 Please select the best answer from the choices provided A B C D.
Answers
Explanation: He paid $12000 total, at a rate of $8 per share. This means he bought 12000/8 = 1500 shares.
He sells these 1500 shares for $15000; this means he received 15000/1500 = $10 per share.
This means he made 10-8 = $2 profit per share.
Answer: 10
Step-by-step explanation:
Miguel paid a total of $12,000 stock that was $8 per share. That's $1,500 you make. 15,000 that was $8 per share. That's $1,875. I dont know if the answer is right, but I wish you well

Answers
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

Answers
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

find the measure of angle A of the following triangle
Answers
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°.

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

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?
Answers
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

HELP PLEASE! Find the area of the figure.
Answers
Answer: 36 square units.
Step-by-step explanation:
First, you can separate the figure into a 4x6 rectangle and a 6x4 isosceles triangle. You can find the area of the rectangle by using the rectangle area formula, A = l x w .
4 x 6 = 24 units
Then, to find the area of the triangle, you can use the triangle area formula, A = [tex]\frac{1}{2}[/tex] b x h .
1/2 x 4 x 6 = 12 units
Finally, you can simply add 24 + 12 to get the total area of 36 units. Since the area is the measure found, you would use the square symbol (²) at the end of the units:
36 units²
