Answer:
118 degrees; 30 degrees
Step-by-step explanation:
2x+14=1/2((6+14x)-58)
2x+14=1/2(-52+14x)
2x+14=-26+7x
40=5x
x=8
6+14(8)=6+112=118

Step-by-step explanation:
a= the height of the triangle=h
[tex]h^{2} = ef[/tex]
by ef, e= 18 & f=4
so...
[tex]h^{2} = 18 \times 4 = 72[/tex]
so you put both of them in a square root
[tex] \sqrt{h} = \sqrt{72}[/tex]
so the answer will be
[tex]h = \sqrt{72} = 6 \sqrt{2} [/tex]

What is the answer to angle A? And do you mind to explain how
Answers
Answer:
45 degrees
Step-by-step explanation:
The sum of the angles of a triangle always adds up to 180.
10x + 8x + 5 + 85 = 180
Simplify by combining like terms.
18x + 90 = 180
Subtract 90 from both sides.
18x = 90
Divide both sides by 18.
x = 5 degrees
But the question didn't ask for x, it asked for angle A. So plug back in.
A = 8x + 5
A = 8(5) + 5
A = 40 + 5 = 45 degrees
Answer:
[tex]45 \: \: degrees[/tex]
Step-by-step explanation:
[tex]10x + 8x + 5 + 85 = 180 \\ 18x + 90 = 180 \\ 18x = 180 - 90 \\ 18x = 90 \\ \frac{18x}{18} = \frac{90}{18} \\ x = 5[/tex]
[tex]angle \: \: \: a = 8x + 5 \\ = 8 \times 5 + 5 \\ = 40 + 5 \\ = 45 \: \: degrees[/tex]

Ms. Lang lives in Lansing, Michigan. Last year, she made 4 round trips to Chicago, Illinois (a distance of 218 miles each way) and 6 round trips to Louisville, Kentucky (a distance of 364 miles each way). How many more miles did she travel in her trips to Louisville than in her trips to Chicago?
Answers
Answer:
1312 miles
Step-by-step explanation:
To solve this, we simply need to subtract the distance she traveled in her trips to Chicago from the distance she traveled in her trips to Louisville.
She made 4 round trips to Chicago, Illinois. Each of the trips is a distance of 218 miles. This means that the total distance she traveled is:
4 * 218 = 872 miles
She made 6 round trips to Louisville, Kentucky/ Each of the trips is a distance of 364 miles. This means that the total distance she traveled is:
6 * 364 = 2184 miles
Therefore, the difference between the distances she traveled is:
2184 - 872 = 1312 miles
She traveled 1312 miles more in her trips to Louisville than in her trips to Chicago.

g(x) = 3(_____)(_____)
Zeros: ______ and ______
Answers
Answer:
g(x) = 3(x-9)(x-5)
Zeros: x = 9 and x = 5.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
[tex]g(x) = 3x^{2} - 42a + 135[/tex]
So
[tex]a = 3, b = -42, c = 135[/tex]
[tex]\bigtriangleup = (-42)^{2} - 4*3*135 = 144[/tex]
[tex]x_{1} = \frac{-(-42) + \sqrt{144}}{2*3} = 9[/tex]
[tex]x_{2} = \frac{-(42) - \sqrt{144}}{2*3} = 5[/tex]
So
g(x) = 3(x-9)(x-5)
Zeros: x = 9 and x = 5.

A park ranger at a large national park wants to estimate the mean diameter of all the aspen trees in the park. The park ranger believes that due to environmental changes, the aspen trees are not growing as large as they were in 1975.
Answers
Answer:
(a) 0.15866
(b) Clustered, with two peaks
(c) Point estimate is 6.3 inches
Margin of error is 0.7 inches
(d) Yes
(e) Stratified sampling method
Step-by-step explanation:
(a) The given information are as follows
Mean diameter of Aspen trees, μ = 8 inches
Standard deviation, σ = 2.5 inches
[tex]z = \frac{x - \mu}{\sigma} = \frac{5.5 - 8 }{2.5} = -1[/tex]
Therefore;
p(x < 5.5) = p(z < -1)
From the z score table, we have p = 0.15866
Therefore, the probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = 0.15866
(b) The distribution of the Aspen trees can be described as clustered and having two peaks around 9.25 inches and 5.25 inches
(c) The point estimate is 5.6 + (7.0 - 5.6)/2 = 6.3
The margin of error = (7.0 - 5.6)/2 = 0.7 inches
(d) Yes, because the 8 inches is outside the range
(e) Stratified sampling method
Here, the Aspen trees are separated into the highland and lowland samples such that the measurement required will be representative of both highlands park and lowlands park.
