Answer:
They're congruent by Side-Angle-Side (SAS)
Step-by-step explanation:
Midpoint Q makes sides LQ and QN equal, as well as MP and QP, so there's a side, depending on which one you choose.
We're told that angle L = angle N, so there's the equal angle.
Finally, we're told that LM = NP, so there's the other side.

6. Teri estimates that it will cost $200,000 to send his daughter to a private college in 16
years. He currently has $125,000 to deposit in an account. What simple interest rate
would
he need so that $125,000 grows info $200,000 in 16 years? Round to the nearest
percent.
How do I solve this?
The simple interest rate need by Teri will be 4%.
Step-by-step explanation:
Given:
Teri has $125,000 to deposit in his accounts so that he gets $200,000 in 16 years along with the simple interest.
To find:
The simple interest rate needed to grow $125,000 into $200,000 in 16 years.
Solution:
The principle amount Teri has = P = $125,000
The total amount Teri wants to have in 16 years = A = $200,000
The simple interest that will Teri earn = S.I
[tex]S.I= A - P =\$200,000-$125,000=\$ 75,000[/tex]
The rate of interest per year = R
The time for which money is deposited = T = 16 years
The simple interest is calculated by the formula:
[tex]S.I=\frac{P\times R\times T}{100}\\\$75,000=\frac{\$125,000\times R\times 16}{100}\\R=\frac{$75,000\times 100}{$125,000\times 16}=3.75\% \approx 4\%[/tex]
The simple interest rate need by Teri will be 4%.

Simple interest rate (R) is 3.75%
Given:
Amount deposit as saving (P) = $125,000
Number of year (n) = 16 year
Amount needed (A) = $200,000
Find:
Simple interest rate (R)
Computation:
Amount of interest (I) = A - P
Amount of interest (I) = 200,000 - 125,000
Amount of interest (I) = 75,000
So,
I = (P)(R)(T)
75,000 = (125,000)(R)(16)
75,000 = 2,000,000(R)
R = 75,000 / 2,000,000
R = 0.0375

Step-by-step explanation:

how do i find the slope
Hi, I'm happy to help!
To find the slope, you need to use the slope formula, where m is the slope:
m=[tex]\frac{y_{2}-y_{1 } }{x_{2} -x_{1} }[/tex]
Slope means rise over run, or how much the line rises per the amount the line moves forward. This equation shows the movement from the y points to show rise, over the difference in the x points to show run.
Now, to find the slope we insert our values, starting with our second y point:
m=[tex]\frac{2-y_{1 } }{x_{2} -x_{1} }[/tex]
Now insert our first y point:
m=[tex]\frac{2-4 }{x_{2} -x_{1} }[/tex]
Now we insert our second x point:
m=[tex]\frac{2-4 }{-3 -x_{1} }[/tex]
And finally our first x point:
m=[tex]\frac{2-4 }{-3 -3 }[/tex]
Now, we solve:
m=[tex]\frac{-2 }{-6}[/tex]
So, our slope is -2/-6, to simplify it, we remove both negatives because they cancel each other out.
m=[tex]\frac{2 }{6}[/tex]
Now, we simplify our fraction by dividing the top and bottom by 2:
m=[tex]\frac{1}{3}[/tex]
So, our slope is 1/3. This means that for every 1 unit the line rises, it goes to the right 3 units. The y-intercept is where the line hits the y axis.
If the question is asking for slope intercept form for the equation, you use y=mx+b
y represents any y coordinate on your line, m represents your slope (1/3), x represents any x coordinate on your line, and b represents your y-intercept (3).
If you were to insert these values, you would get:
y=[tex]\frac{1}{3}[/tex]x+3
You use this to find what a y coordinate would be so you can draw your line.
For the next equation we do the same thing:
m=[tex]\frac{y_{2}-y_{1 } }{x_{2} -x_{1} }[/tex]
Insert our values:
m=[tex]\frac{4-1}{2-(-4)}[/tex]
Get rid of the double negative:
m=[tex]\frac{4-1}{2+4}[/tex]
Solve:
m=[tex]\frac{3}{6}[/tex]
Simplify:
m=[tex]\frac{1}{2}[/tex]
Now that we know our slope, let's plug it in to our slope intercept form equation.
y=[tex]\frac{1}{2}[/tex]x+3

Your college professor tells you he will give you a 30%-30%-40% split on grades between homework, quizzes, and test. However which ever category you have the highest average and will be able to 40% category. What will your final grade be if your homework average of 62, your quiz average is 93, and your test average 60?
Here we want to calculate percentages of different values to find your final grade, we can conclude that your final grade will be 73.8
We know that:
you have an average of 62 in homework
you have an average of 93 on quiz
you have an average of 60 on test.
Your final grade will be a 30%-30%-40% of the above average scores, such that the 40% will be of the highest average.
We can see that the highest one is on quiz, then your final grade will be:
the 40% of your average quiz grade plus the 30% of your average homework grade plus the 30% of your average test grade.
This will be:
[tex]g = \frac{40 \%}{100 \%}*93 + \frac{30 \%}{100 \%}*62 + \frac{30 \%}{100 \%}*60\\\\g = 0.4*93 + 0.3*62 + 0.3*60 = 73.8[/tex]

-t = 9 (t - 10)
what is t?
Answer: t = 9
Step-by-step explanation:
Given
-t = 9 (t - 10)
Expand parentheses and apply the distributive property
-t = 9 · t - 9 · 10
-t = 9t - 90
Subtract 9t on both sides
-t - 9t = 9t - 90 - 9t
-10t = -90

a tank is 4÷5 full of water. after drawing off 190 litees of water,it is just 1÷6 full. what is the capacity of the tank
Hey there! I'm happy to help!
Let's have the capacity be c. The tank is currently at 4/5c. We subtract 190 and then we are at 1/6c. Let's set this up as an equation and solve it.
4/5c-190=1/6c
We want to get the c all by itself to see the capacity of the tank. Let's get all of the c values on the left side of the equation and the numbers on the right by using inverse operations.
4/5c-190=1/6c
Add 190 to both sides.
4/5c=1/6+190
Subtract 1/6 from both sides.
19/30c=190
Divide both sides by 19/30.
c=300
So, the capacity of the tank is 300 liters of water.

Read explanation Please (I spent alot of time on it and its important to understand where the answer came from not just the answer!)
Step-by-step explanation:
This problem is in the form of y=mx+b where m is the ratio y grows accordinly to x and b is the value of y when x is 0 (mx0 is 0, 0+b is b).
In you problem we can identify that 1 is the y intercept or when x is 0. All we have to do is find another point since 2 points make alike. Let's say x was 1. 43 * 1 +1 = 44 so when x is 1 y is 44.
Our two points are, (0,1)(1,44)

=============================================================
Explanation:
Let's say that all of the 11 songs are 2 minutes each, which is just a bit under the "2 minute 1 second" mark of the shortest song. I'm going for the lowest time value possible and rounding to the nearest minute.
This would mean the entire album is 2*11 = 22 minutes long. This is the lower bound or the shortest the album can be.
If we go to the other end of the spectrum, and say each song is 6 minutes (I rounded "5 minutes 37 seconds" up to the nearest minute), then the album is now 6*11 = 66 minutes long. This is the upper bound or the longest the album can be.
While we don't know how long the album is exactly, due to the fact we don't know the individual song lengths (other than the shortest and longest songs), we do know 100% that the album length is somewhere between 22 minutes and 66 minutes.
In other words, 22 < x < 66 where x is the album length in minutes.
Of the four answer choices, 44 is the only one that fits, i.e. 22 < 44 < 66.
So I would say 44 minutes is a reasonable estimate. Or better yet, we can rule out 4 minutes, 88 minutes and 10 minutes as they don't fit in the interval 22 < x < 66.
