Answer:
The value of x = 9
Step-by-step explanation:
Angle Bisector Theorem
An angle bisector of a triangle would cut the opposite side into two segments that are proportional to the other two sides of the triangle.
Thus,
[tex]\frac{x}{15}=\:\frac{12}{20}[/tex]
Cross Multiply the expression
[tex]\:20\times x=12\times 15[/tex]
Divide both sides by 20
[tex]\frac{20x }{20}=\frac{180}{20}[/tex]
[tex]x=9[/tex]
Therefore, the value of x = 9

What is part- to part ratio?
Answer:
Part-to-part ratios provide the relationship between two distinct groups
Step-by-step explanation:
For example, the ratio of men to women is 3 to 5, or the solution contains 3 parts water for every 2 parts alcohol. Part-to-whole ratios provide the relationship between a particular group and the whole populations (including the particular group).

Explain it too and what specific polynomial subject.
Answer:
C
Step-by-step explanation:
Expand the factors and compare the coefficients of like terms.
Given
(mx + 2)(3x - 5) ← expand using FOIL
= 3mx² - 5mx + 6x - 10
Compare to 12x² - 14x - 10
For the 2 to be equal, then the coefficients of like terms must be equal.
Compare coefficients of x² terms
3m = 12 ( divide both sides by 3 )
m = 4 → C

Answer:
Conclusion:
The rate of change of function 1 = 3
The rate of change of function 2 = 5/3
Hence, function 1 has a greater rate of changeThe initial Value of function 1 = y = 2
The initial Value of function 2 = y = 3
Hence, function 2 has a greater initial value.Step-by-step explanation:
Function 1)
Determining rate of change for function 1:
x 1 2 3 4
y 5 8 11 14
Finding the rate of change or slope using the formula
Rate of change = m = [y₂-y₁] / [x₂-x₁]
Taking any two points, let say (1, 5) and (2, 8)
Rate of change = m = [8-5] / [2-1]
= 3/1
= 3
Therefor, the rate of change of function 1 = m = 3
using point-slope form to determine the function equation
y-y₁ = m (x-x₁)
where m is the rate of change or slope
substititng m = 3 and the point (1, 5)
y - 5 = 3(x - 1)
y - 5 = 3x-3
y = 3x-3+5
y = 3x + 2
Thus, equation of function 1 will be:
y = 3x + 2
Determining Initial Value for Function 1:
substituting x = 0 in the equation to determine the initial value
y = 3(0)+2
y = 0+2
y = 2
Therefore, the initial Value of function 1 will be: y = 2
Function 2)
Determining the rate of change for function 2:
Given the function 2
[tex]y\:=\:\frac{5}{3}x+3[/tex]
comparing with the slope-intercept form of a linear function
y = mx+b where m is the rate of change
so the rate of change of function 2 = m = 5/3
Determining Initial Value for Function 2:
substituting x = 0 in the equation to determine the initial value
[tex]y\:=\:\frac{5}{3}x+3[/tex]
[tex]y\:=\:\frac{5}{3}\left(0\right)+3[/tex]
[tex]y = 0+3[/tex]
[tex]y = 3[/tex]
Therefore, the initial Value of function 2 will be: y = 3
Conclusion:
The rate of change of function 1 = 3
The rate of change of function 2 = 5/3
Hence, function 1 has a greater rate of changeThe initial Value of function 1 = y = 2
The initial Value of function 2 = y = 3
Hence, function 2 has a greater initial value.plss help!!! (15pts)

The triangle has an area of 90cm^2 what size can angle x be
Answer:
[tex]x=30°[/tex]
Step-by-step explanation:
[tex]Area=\frac{18*20sinx}{2} \\ \Leftrightarrow 90=\frac{18*20sinx}{2} \\ \Leftrightarrow sinx=\frac{90*2}{18*20}=\frac{1}{2}\\ \Leftrightarrow x=30°[/tex]

What is the number of cycles of y=9cos(θ/4+3π/2)+4 between 0 and 2π?
Answer: Choice C) 1/4
===================================================
Work Shown:
Let's rearrange terms a bit to say the following:
[tex]y = 9\cos\left(\frac{\theta}{4}+\frac{3\pi}{2}\right)+4\\\\y = 9\cos\left(\frac{1}{4}\theta+\frac{3\pi}{2}\right)+4\\\\y = 9\cos\left(\frac{1}{4}\left(\theta+6\pi\right)\right)+4\\\\y = 9\cos\left(\frac{1}{4}\left(\theta-(-6\pi)\right)\right)+4\\\\[/tex]
The last equation is in the form [tex]y = A\cos\left(B\left(\theta-C\right)\right)+D\\\\[/tex]
where,
|A| = amplitudeB handles the period. Specifically T = 2pi/B, where T is the periodC handles the phase shift, aka horizontal shiftingD determines the midline and the vertical shiftingWe only need to worry about the value of B.
In this case, B = 1/4
So,
[tex]T = \frac{2\pi}{B}\\\\T = 2\pi \div B\\\\T = 2\pi \div \frac{1}{4}\\\\T = 2\pi \times \frac{4}{1}\\\\T = 8\pi\\\\[/tex]
The period is 8pi. Every 8pi units, a full cycle is completed.
However, we're not going from 0 to 8pi, but instead from 0 to 2pi.
The given interval is 2pi units wide. This is (2pi)/(8pi) = 1/4 of a full cycle. This is why choice C is the answer.
Kelsey went bowling. It cost her a one-time fee of $3.50 to rent shoes, and $6.50 per game she played. She does not want to spend more than $23.00. Write an inequality that could be used to determine how many games she can afford to play
Answer: 6.50x + 3.50 < 23
Step-by-step explanation:
I believe this is correct because the total of the one-time fee and the money per game she played, should be less than $23
Answer:
she can only afford to play 3 games
Step-by-step explanation:
3.50+6.50=10.00
23.00-10.00=13.00
13.00-6.50=7.50
7.50-6.50=1.00
A shuttle bus leaves from my office at a speed of 32 miles per
hour. How many hours will it take to arrive at my house if the
distance from the office to my house is 83 miles? Enter your
answer rounded to the nearest tenth of an hour.
hrs
Answer:
2.6 hours
Step-by-step explanation:
use distance formula: d = r * t
83 = 32t
83/32 = t
2.6 = t
2.6 hours is 2 hours, 36 minutes
Which phrase matches the equation -3r + 5 = 28?
The sum of three and a number times negative five gives twenty-eight.
The sum of negative five plus three times a number equals twenty-eight.
The product of negative three and a number plus five equals twenty-eight.
The product of three times a number equals twenty-eight.
Answer:
Option "3" is correct
Step-by-step explanation:
Given:
equation -3r + 5 = 28
Explanation:
Assume;
Given number = r
The product of negative three and a number
⇒ -3(r)
Plus five equals twenty-eight
⇒ -3r + 5 = 28
So,
Option "3" is correct .

Answer:
6.08 x [tex]10^{-7}[/tex]
Step-by-step explanation:
For scientific notation, you want one digit to be in front of the decimal point -- so you need to move the decimal point 7 spaces to the right -- which is the same as dividing by 10^7, or multiplying by 10^(-7). So you're left with 6.08 x 10^(-7)

WILL MARK BRAINLIEST!
Answer:
x = 6
Step-by-step explanation:
Based on the two secants intersecting theorem, thus:
(x + 4)*4 = (3 + 5)*5
x*4 + 4*4 = (8)*5
4x + 16 = 40
4x + 16 - 16 = 40 - 16 (subtraction property of equality)
4x = 24
4x/4 = 24/4 (Division property of equality)
x = 6
