Answers
Step-by-step explanation:
1.
the indicated point in the middle is the center point of the circle.
the line perpendicular to a chord going through that center solid the chord in half.
so,
x = 9
2.
Pythagoras
c² = a² + b²
13.5² = x² + 10.4²
182.25 = x² + 108.16
x² = 74.09
x = 8.607554821...
3.
Intersecting Chords Theorem
(part one of chord 1)×(part two of chord 1) =
= (part one of chord 2)×(part two of chord 2)
6x = 10×9 = 90
x = 90/6 = 30/2 = 15
4.
Intersecting Chords Theorem again
x(x+3) = 4×10 = 40
x² + 3x = 40
x² + 3x - 40 = 0
generation solution to a quadratic equation
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 3
c = -40
x = (-3 ± sqrt(3² - 4×1×-40))/(2×1) =
= (-3 ± sqrt(9 + 160))/2 = (-3 ± sqrt(169))/2 =
= (-3 ± 13)/2
x1 = (-3 + 13)/2 = 10/2 = 5
x2 = (-3 - 13)/2 = -16/2 = -8
negative values for a length do not make sense, so x = 5 is our solution
5.
Intersecting Chords Theorem
(x+1)×4 = (x-1)×5
4x + 4 = 5x - 5
9 = x

Answers
Answer:
280 in ^2
Step-by-step explanation:
Hi ok heres how I did this:
SA of rectangular prism: S = 2(lw + lh + wh)
SA of triangle top thing(whats it called???): Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh
So basically for the square part, the surface area is
2(4*4+4*12+4*12), or 224
For the triangle part, the surface area is
4+4+4, or 12*4+2*4, or 48+8, or 56
224+56=280
The thing is I don't know why it says round though. Theres a chance its incorrect if they want something with a decimal. Let me know.

Linda rented 8 movies and 4 video games for a total of $37. The next month she rented 3 movies and 2 video games for a total of $17.
Find the rental cost for each movie and video game.
Answers
Rental cost for each video game $6.25
Explanation:
m = rental cost of each movie
g = rental cost of each game
Set up:
8m + 4g = 37
3m + 2g = 17
Modify for elimination:
3 (8m + 4g = 37) ———> 24m + 12g = 111
8 (3m + 2g = 17) ———> 24m + 16g = 136
Subtract:
24m + 16g = 136
- 24m - 12g = -111
——————————
4g = 25
Divide:
4g = 25
g = 25/4
g = 6.25
So each game is $6.25
Now plug in “g” to one of the original equations and solve for “m” to find the rental cost for each movie
3m + 2 (6.25) = 17 (multiply 2 & 6.25)
3m + 12.50 = 17 (subtract 12.50 from sides)
3m = 4.50 (divide both sides by 3)
m = 1.50
So each movie rental is $1.50
Calculate the mean of the data set below. 28,40,53,39,45
Answers
Answer: 41.
Step-by-step explanation: To find the mean of a data set, you first need to add all the numbers together. It should look like this:
28 + 40 + 53 + 39 + 45 = 205.
The next step is to divide 205 by how many numbers you have in the data set. In this case, you have 5 numbers in the data set. Your work should look like this:
205 / 5 = 41.
Therefore, the mean of the data set is 41.
Hope this helps! :)

what is 30x120? since i dont know how to multiply by doubles :)
Answers
Answer:
The answer to 30*120 is 3,600
Answer:
30 times 120 equals 3600
Step-by-step explanation:
One thing that is really easy to use to multiply is a calculator (either online or a hand-held one). But here is how you can multiply without a calculator...
Set up an equation on a piece of paper like how it is shown right below...
30
x 120
Then, times the last digit (so the zero) of the bottom number. (But it doesn't really matter what order you put them in). Then, times it by the last digit of the top number. So that would equal 0! So as shown below, you would put the answer like so...
30
x 120
0
Then, you do 0 (last digit of bottom number) times 3 (you keep going left of the top number's digits). So that would also equal 0.
30
x 120
00
0
Then you add a zero below, since we are now moving on to the next number to the left of the last digit of the bottom number (hopefully this is making sense). Then you do the exact same thing.
30
x 120
00
600
Now that we're done with that, we add two zeros this time, since we are in the hundreds now. So it is to the next number now! (1) And then we do the exact same thing again!
30
x 120
00
600
3000
Alright, that's done! Now we add all those answers together (0+600+3000)
And that gives us our answer! 3600!
Hopefully that made sense! :)

Step-by-step explanation:
General form of an arithmetic sequence:
[tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsGiven:
[tex]a_{21}=-32[/tex][tex]a_{50}=-119[/tex]To find the 43rd term we need to construct an equation for the nth term. To do this, find the first term and the common difference by substituting the given information into the general formula to create a system of equations that can be solved.
[tex]\begin{aligned} \underline{\textsf{Equation 1}}} \\ a_{21} & =-32 \\ \implies a+(20-1)d & = -32 \\a+20d & =-32 \end{aligned}[/tex]
[tex]\begin{aligned} \underline{\textsf{Equation 2}}} \\ a_{50} & =-119 \\ \implies a+(50-1)d & = -119 \\a+49d & =-119 \end{aligned}[/tex]
Subtract Equation 1 from Equation 2 to eliminate a:
[tex]\begin{array}{r l}a+49d & = -119\\- \quad a+20d & = -32\\\cline{1-2}29d & = -87\end{aligned}[/tex]
Solve for d:
[tex]\implies d=\dfrac{-87}{29}=-3[/tex]
Substitute the found value of d into one of the equations and solve for a:
[tex]\implies a + 20(-3)=-32[/tex]
[tex]\implies a=28[/tex]
Substitute the found values of a and d into the general formula to create an equation for the nth term:
[tex]\implies a_n=28+(n-1)(-3)[/tex]
[tex]\implies a_n=31-3n[/tex]
Finally, substitute n = 43 into the found formula to find the 43rd term of the sequence:
[tex]\implies a_{43}=31-3(43)=-98[/tex]
