Triangle A B C is cut by line segment M N. Line segment M N goes from side A B to side B C. The length of M N is 9 feet. The len
katrin [286]

Answer:

The length of AC is 18 feet ⇒ 4th answer

Step-by-step explanation:

* Lets revise an important theorem for a triangle

- <em>If a line segment joining the mid-points of two sides of a triangle, </em>

<em>   then this line segment is parallel to the third side of the triangle and</em>

<em>   equal half its length</em>

<em></em>

* Lets use this theorem to solve the problem

- In Δ ABC

∵ Line MN intersects the sides AB at M

∵ MA = MB

∴ M is the mid point of the side AB

∵ Line MN intersects the sides BC at N

∵ NC = NB

∴ N is the mid point of the side BC

- <em>By using the theorem above</em>

  In Δ ABC

∵ M is the mid-point of AB

∵ N is the mid-point of BC

∴ MN // AC

∴ MN = \frac{1}{2} AC

∵ The length of MN = 9 feet

∵ MN = \frac{1}{2} AC

∴ 9 = \frac{1}{2} AC

- Multiply both sides by 2

∴ AC = 18 feet

* The length of AC is 18 feet

If A+D=117kg , A+M=88kg and M+D=161kg whats there total weight<br><br>thx in advance
garri49 [273]
Think of A as a constant - with D it's 117 and with M it's 88

So the difference between D and M is 29   (117-88)

We also know that M + D = 161

Let's substitute in the problem  We will leave M equal to M and rewrite D as M+29 since it is 29 kg heavier.
M + M + 29 -161  or 2M +29 = 161 Subtracting 29 from both sides we get 2M=122
Now divide both sides two and get M=61
Since D is M+29 it is 61+29 or 100kg
Finally A + M = 88   A + 61 - 88   Subtract 61 from both sides and get A=17
So there you have it:
A=17kg
M=61kg
D=100kg and it works in all three equation in your problem (try it to check)

Doris uses 6 square pieces of fabric to make one scarf. Each side of a square piece of fabric is one third yard in length. Doris
brilliants [131]

Answer:

5 large pieces of fabric.

Step-by-step explanation:

Length of each side of a square piece of fabric =\frac{1}{3} yard

Area of a Square = Length X Length

Area of one square piece of fabric = \frac{1}{3} X \frac{1}{3} =\frac{1}{9} square yard.

To make one scarf, Doris uses 6 square pieces.

Area of one scarf =  6 X \frac{1}{9}= \frac{6}{9}=\frac{2}{3} square yard

Each large pieces of fabric is one-third yard long and 2 yards wide.

This is clearly a rectangle,

Area of a Rectangle = Length X Width

Area of each large piece of fabric=\frac{1}{3}X 2=\frac{2}{3} square yard.

Since the Area of one scarf is equal to the area of each large piece of fabric, in order to make 5 scarves, Doris would need 5 large pieces of fabric.
