Find the value of x.
Answer:
x = 5
Step-by-step explanation:
14x + 22x = 180
36x = 180
x = 5
Answer:
[tex]\huge\boxed{⎆Answer\hookrightarrow}[/tex]
The 2 angles in the given picture form supplementary angles. So, together they'll add up to 180°.
[tex]14x + 22x = 180 \\ 36x = 180 \\ x = \frac{180}{36} \\ x = 5[/tex]
⇻ The value of X is 5.
Solve For w
and X
x?
Answer:
w = 12.79
x = 5.81
Step-by-step explanation:
First, solve for w:
Find the last angle of the triangle. The sum of all the angles in a triangle is
180 degrees.
A+90+52=180, this gives you angle A as 38. Use this to find w
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
Cos(B) = adj/hyp so Cos(B) = a/c rewrite as
c=10/Cos(B) or c = 10/0.61566147
c= 16.24
Now find the last side of the triangle using the Pythagorean theorem.
[tex]a^{2} +b^{2} =c^{2} \\or\\b^{2} = c^{2} -a^{2}[/tex]
which gives you b or in this case w = 12.79
You then need w for the 2nd triangle as well as the angle 31 and the angle next to 52, which is 180-52 = 128. The other missing angle x to the triangle is 180-31-128 = 21
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.
sin(x)/x=sin(B)/b=sin(C)/c
sin31/b=sin(128)/12.79 = 8.359 then
sin21/x = sin31/8.359
therefor x = 5.81

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Demetria got a score of 85.185.1; this version has a mean of 61.1 and a standard deviation of 12. Vincent got a score of 299.2; this version has a mean of 264 and a standard deviation of 22. Tobias got a score of 7.26; this version has a mean of 7.1 and a standard deviation of 0.4.
Required:
If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job?
Answer:
Due to the higher Z-score, Demetria should be offered the job.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
Whichever applicant had grade with the highest z-score should be offered the job.
Demetria got a score of 85.1; this version has a mean of 61.1 and a standard deviation of 12.
For Demetria, we have [tex]X = 85.1, \mu = 61.1, \sigma = 12[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{85.1 - 61.1}{12}[/tex]
[tex]Z = 2[/tex]
Vincent got a score of 299.2; this version has a mean of 264 and a standard deviation of 22.
For Vincent, we have [tex]X = 299.2, \mu = 264, \sigma = 22[/tex].
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{299.2 - 264}{22}[/tex]
[tex]Z = 1.6[/tex]
Tobias got a score of 7.26; this version has a mean of 7.1 and a standard deviation of 0.4.
For Tobias, we have [tex]X = 7.26, \mu = 7.1, \sigma = 0.4[/tex].
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{7.26 - 7.1}{0.4}[/tex]
[tex]Z = 0.4[/tex]
Due to the higher Z-score, Demetria should be offered the job.

Answer: 4.2
Step-by-step explanation:
Here's the formula for how to find the hypotenuse: (a and b are the two legs for the triangle-- it doesn't matter which leg is a and which leg is b, but c MUST be the hypotenuse)
[tex]a^2+b^2=c^2[/tex]
[tex]1.9^2+3.8^2=c^2[/tex]
[tex]3.61+14.44=c^2[/tex]
[tex]18.05=c^2[/tex]
[tex]\sqrt{18.05} =c[/tex]

Find the surface area of the regular pyramids. Round your answer to the nearest tenth.
Answer:
S.A = 147.35 cm²
Step-by-step explanation:
Surface area of the triangular pyramid = base area + ½(perimeter of base*slant height)
Base area = ½*bh
b = 7 cm
h = 6.1 cm
Base area = ½*7*6.1 = 21.35 cm²
Perimeter of triangular base = 7 + 7 + 7 = 21 cm
slant height = 12 cm
Plug in the values into the equation
S.A = 21.35 + ½(21*12)
S.A = 21.35 + 126
S.A = 147.35 cm²
What is the surface area?
Answer:

Analyze the effects on the graph of f(x) = 10% that result from the parameter
changes in the function, h(x) = 5(10)*2 +6. Explain how each transformation
appears in the equation and its effect on the original function, R(x) = 10%. Be
sure to use mathematical language in your explanation.
Answer:
Step-by-step explanation:
Parent function has been given as,
f(x) = [tex]10^x[/tex]
If this function is vertically stretched by a scale factor 5,
g(x) = k[f(x)]
g(x) = [tex]5(10)^x[/tex]
Then function 'g' is shifted right by 2 units, new function will be,
k(x) = g(x-2)
k(x) = [tex]5(10)^{x-2}[/tex]
Finally the function 'k' is shifted up by 6 units, then the function 'h' will be,
h(x) = k(x) + 6
h(x) = [tex]5(10)^{x-2}+6[/tex]

Best answer gets brainliest!! Please help
Answer:
.52
Step-by-step explanation:
We can write an equation
supports/all
we can see that 27 males and 25 females support which means that
27+25= 52 total people support
now we just need to find the number of people surveyed
we do this by summing everything
27+25+18+13+5+12=100
52/100 = .52
Answer:
.52
Step-by-step explanation:
Add both male and female supports to get 52
then add all the numbers to get a total of 100
52/100=.52
A max subscription for Twitch, a streaming service, costs a flat fee of $25. You can then also buy small subscriptions for others for $5 per subscription. Johnny is trying to budget the amount of money he wants to spend.
Let y represent the total amount of money spent, and x represent the number of small subscriptions he purchases.
Answer:
y = 25 + 5x
Step-by-step explanation:
Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.

Answer:
a. Sin B = 15/17
b. Cos B = 8/17
c. Tan B = 15/8
Step-by-step explanation:
Recall: SOHCAHTOA
Reference angle = B
Opp = 15
Adjacent = 8
Hypotenuse = 17
a. Sin B = Opp/Hyp (applying SOH)
Substitute
Sin B = 15/17
b. Cos B = Adj/Hyp
Substitute
Cos B = 8/17
c. Tan B = Opp/Adj
Substitute
Tan B = 15/8
Find the equationFind the equation (in terms of
x
) of the line through the points (-4,-5) and (3,5) (in terms of x ) of the line through the points (-4,-5) and (3,5)
Answer:
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-4, 3)
Points on the y-axis (y1, y2) = (-5, 5)
To find the equation of line in terms of x;
First of all, we would determine the slope of the line;
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {5 - (-5)}{3 - (-4)} [/tex]
[tex] Slope, m = \frac {10}{7} [/tex]
Slope, m = 10/7
Next, we find the equation;
y - y1 = m(x - x1)
y - (-5) = 10/7(x -(-4))
y + 5 = 10/7(x +4)
