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

The two triangles are similar.
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]

Carbon-14 has a half-life of approximately 5,730 years. This exponential decay can be modeled with the function N(t) = N0.
If an organism had 200 atoms of carbon-14 at death, how many atoms will be present after 14,325 years? Round the answer to the nearest hundredth.

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°.

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

Evaluate Functions From a Graph
Answer:
f(-2) = -2
Step-by-step explanation:
Start on the graph at the center, (0,0), right where the x- and y-axis cross.
The numbers on the x-axis are the x's (look left or right) The problem says to find f(-2). This means let x = -2. So skip over to the left to where x = -2, then go down until you run into the curve. You have to look at the y-axis to find the numerical answer.
Here are some other ones on this graph, to see if you can see how this works. **These two -2's are totally different. The answer -2 is not because the problem had a -2 in it.**
other examples on this graph:
f(-1) = -3
f(0) = -2
f(1) = 1
f(-3) = 1
f(-4) = 6
f(2) = 6

On a balance scale, five spools and three thimble balance sixteen buttons. Also, three spools balance one thimble and four buttons. How many buttons will balance one thimble?
Answer:
2 buttons
Step-by-step explanation:
Let s = spool, t = thimble, b = button
5s + 3t = 16b
3s = 1t + 4b
5s + 3t = 16b
3s - t = 4b
-15s - 9t = -48b
(+) 15s - 5t = 20b
------------------------------
-14t = -28b
t = 2b
Answer: 2 buttons

The answer is B
Step-by-step explanation:
Find the axis of symmetry
Use the formula -b/2a
2x^2-8x+6
- (-8)/2(2)
8/4
2
The axis of symmetry is at x=2, which means that the vertex is at x=2
Substituting x=2 into the quadratic:
2(2)^2-8(2)+6
2*4-16+6
8-16+6
-2
The vertex is at (2,-2)
The graph where this applies is B.
Therefore, the answer is B.

HELP PLEASE! Find the area of the figure.
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
