Answer:

The length of MN is 58 cm.

Step-by-step explanation:

In the given figure we can see that AM = MB

So, M is the mid point of AB.

Also, BN = NC ( Consider the given figure )

So, N is the mid point of BC.

Since M and N are the midpoints of AB and BC .

So, by mid segment theorem which sates that the segment joining the midpoints of any two sides of a triangle will be parallel to the third side of the triangle and half its length.

⇒ MN is parallel to AC

and

$MN = \frac{1}{2} AC$

$MN = \frac{1}{2} (116)$

$MN = 58 cm$

Thus , the length of MN is 58 cm.

Answer:

The length of MN is 58 cm.

Step-by-step explanation:

Given the figure in which

AM=MB, CN=NB

So, M and N are the mid point of AB and BC

∴ By mid point theorem which states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side of the triangle and half the length of third side.

⇒ MN is parallel to AC and also half of third side i.e AC

$MN=\frac{1}{2}AC=\frac{1}{2}\times 116=58 cm$

Hence, the length of MN is 58 cm.

Thus , the length of MN is 58 cm.

Macy has a 20 year adjustable rate mortgage with a fixed rate for the first 7 years. In the 8th year, the interest rate rises to

Crank

The answer is indeed 3,725.90. The reason why is because with each adjustment, you take the remaining balance and calculate a fixed rate loan for the remaining time period at the new rate. When you follow that procedure with the data you already have, you get that answer.

Lilit [14]

Answer:

t=p*34

Step-by-step explanation:

t=p*T, where T is the bill for the table Joe waited on, p is the percent tip and t is the tip left for the waiter

In this situation, the bill is 34, so lets plug that in

t=p*34

Helooooo?!!!!! 30 whole points

Answer:

I believe C, or the answer you have chosen, is correct.

Step-by-step explanation:

In this question, we add like, AKA similar, terms.

There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:

x^2

There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:

x^2 - x

We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:

x^2 - x + 6.

See how easy that was? :) Hope this helps you and you get a good grade on your test!!

Please rate my answer and give me Brainliest!!!!

Have an awesome rest of your day! :)

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 18

kogti [31]

Answer: One side could be 18 and the other side will be 33.

Step-by-step explanation:

Side #1 = 18
Side #2 = 2x - 3
Side #3 = x

One way of setting up the inequality is: Side #2 + Side #3 > Side #1

$2x-3+x>18\\3x-3>18\\3x>18+3\\3x>21\\x>7$

Another way of setting up the inequality is: Side #1 + Side #3 > Side #2

$18+x>2x-3\\18+3>2x-x\\x$

Final way of setting up the inequality is: Side #1 + Side #2 > Side #3

$18+2x-3>x\\15>x-2x\\15>-x\\x>-15$

Therefore, we have the range for our value of x, which is between 7 and 21. Any possible value between works. Negative measurements are rejected. One of the sides would equal the x-value, while the other side would equal the value of 2x-3.
