Answer:
3 1/3
10/3
3.333
Step-by-step explanation:
These two triangles are similar. Since they share two angles, the right angle and angle EBD and ABC are congruent. By AA similarity rule, they are similar triangles.
Since they are similar we can set up a proportion of the triangles since similar triangles have proportional side length.
Side AC corresponds with DE
Side AB corresponds with BE
Side BC corresponds with BD
So we can use this proportion theorem, or angle bisector theorem
[tex]\frac{ac}{ab}=\frac{de}{be}[/tex]
Plug in the numbers.
[tex]\frac{3}{5} =\frac{2}{x}[/tex]
Cross multiply
3x=10
x=10/3
Simplify is
3 1/3
As a decimal it equal 3.333

Answer:
f(x) = x - 2
Step-by-step explanation:
If you notice, the f(x) or y value is 2 less than the x value for every x value listed. This means that x - 2 = y. Just by rearranging this equation, you are given an equation in the linear form y = mx + b:
y = x - 2
Since the y coordinate is being represented by f(x) in the equation, as it is a function, the answer would be:
f(x) = x - 2

Hope it is helpful....What is the slope of the line represented in the table of values?
A.)9
B.)118
C.)19
D.)18
(PLEASE HELP)
Answer:
Slope = 9
Step-by-step explanation:
Point (3,27) and (5,45)
m = (45-27)/(5-3)
18/2 = 9
Answer:
9
Step-by-step explanation:
To find the slope of a line, one of the methods is to look for the rise over run, or the change in y over the change in x. If we just look at the first few numbers on the chart, we can see that the change in y (for the first two numbers) is 18, and the change in x (for the first two numbers) is 2. So our slope is 18/2, or 9.
I think this is correct, I hope it helped!! :3

Holly buys a $22 shirt for 20% off. The tax rate in her city is 6.5%. What is the total amount she paid for the shirt? Round to the nearest cent.
A.$2
B.$18.74
C.$24.10
D.$8.50
The total amount Holla paid for the shirt is: B. $18.74
Given the following data:
Cost of shirt = $22Discount = 20% Tax rate = 6.5%To find the total amount she paid for the shirt:
First of all, we would determine the discount on the shirt:
[tex]Discount = \frac{20}{100} \times 22\\\\Discount = 0.2 \times 22[/tex]
Discount cost = $4.4
[tex]Selling\; price = Cost\;price - Discount \\\\Selling\; price = 22 - 4.4[/tex]
Selling price = $17.6
Next, we would determine how much tax is to be paid:
[tex]Tax \;cost = \frac{6.5}{100} \times 17.6\\\\Tax \;cost = 0.065 \times 17.6[/tex]
Tax cost = $1.444
[tex]Total\;amount = selling \;price + tax\;cost\\\\Total\;amount = 17.6 + 1.444[/tex]
Total amount = $18.74

If E is the circumcenter of MNP, find each measure.
Answer:
NE = 37
MD = 3[tex]\sqrt{65}[/tex]
Step-by-step explanation:
NOTE: This explanation assumes you have basic knowledge of circumcenters, the Pythagorean Theorem, and pre-algebra
Assuming the calculations you so kindly did for us are correct:
To find NE
Simply plug x, which you found was 5, into the equations 13x-28, then you have the length of the line NE, which is 37.
So
NE = 37
To find MD
A little bit trickier, but still simple. You end up having to use the Pythagorean Theorem. Since NE = ME, you know that ME is equal to 37. Since triangle MED is a right triangle, and you're given on the the side ED (which is 28), and the hypotenuse, ME (which is 37), you can say that
28^2 + b^2 = 37^2
784 + b^2 = 1369
b^2 = 585
b = 3[tex]\sqrt{65}[/tex]
(In which b is MD)
So
MD = 3[tex]\sqrt{65}[/tex]

In a certain university, there was a certain number of students who attended the general orientation. The number of male students was five times as many as that of female students. When 324 male students left the orientation, the number of female students became twice as many as that of male students. How many students attended the orientation?
Answer:
fewfefdfgtrusergwer h4yr sfd gw gr.
Step-by-step explanation:
The number of students who attended the orientation in that considered university was 432
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, first, let we assume the number of male students and female students who attended the orientation:
m = number of male students attending the orientationn = number of female students attending the orientationFrom the description, we have:
m = 5 times n = 5n
and
(m - 324)'s twice = n
or 2(m-324) = n
Thus, we get system of two equations as:
[tex]m = 5n\\2(m-324) = n[/tex]
Substituting value of m from first equation in second, we get:
[tex]2(5n - 324) = n\\10n -648 = n\\\\n = \dfrac{648}{9} =72[/tex]
Putting this value of n back in first equation, we get:
[tex]m = 5n = 5 \times 72 = 360[/tex]
Assuming that there were only two gendered students in university orientation (males and females), we get:
Total number of students who attended the orientation = m + n = 360 + 72 = 532
Thus, the number of students who attended the orientation in that considered university was 432
