We can represent the problem as shown in the attached drawing

L1=x1

L2=x2

L=x------------distance of the center of mass

we have that

L1/L2=m2/m1------------------> L1*m1=L2*m2------------->m2=L1*m1/L2

moment = Md

the moment about O is defined to be

m1*L1+m2*L2=(m1+m2)*L

L=(m1*L1+m2*L2)/(m1+m2)

m1*L1+m2*L2=2*m1*L1--------remember-------------------->L1*m1=L2*m2

L=(2*m1*L1)/(m1+L1*m1/L2)

L=(2*m1*L1)/(m1*L2+L1*m1)/L2=(2*m1*L1)*L2/(L2*m1+L1*m1)

L=(2*L1*L2)/(L1+L2)

the coordinates of the center of mass are (L,0)

In a wood there are 420 silver birch trees, 160 oak trees and 300 wild berry trees. what percentage of the trees are oak trees?
Alex73 [517]
I would be happy to help!
First you need to find the total amount of trees by adding up all of the different trees:
420+160+300=880
Next you need to divide the amount of oak trees by the amount of trees in the woods:
160÷880=0.182 (rounded)
Finally to find the precentage we need to multiply the 0.182 by 100 to get the precentage of 18.2% oak trees.

Answer:

b.12

Step-by-step explanation:

<u>Key skills needed: Interior Angle Measure Theorem, Equation Creation</u>

1) First, we need to classify this shape. It has 7 sides, which means that we can use the Interior angle Theorem to find out the sum of all the interior angle measures

The theorem is:    S = (n - 2)180

S is the sum of all interior angle measures

n is the number of sides of the polygon

2) With this, we can plug in 7 for "n" (Since the figure has 7 sides) and get:

---> S = (7-2)180

---> (7-2) is 5 since 7 - 2 = 5 so --> S = 5(180)

---> 5(180) is the same as 5 x 180 which is 900 so --> S = 900

This means that the sum of all interior angles is 900 degrees.

3) Now, we have to find out the sum of all the angles that they gave us so:

---> 10x + 10x + 9 + 133 + 9x + 14 + 12x - 9 + 10x + 5 + 136 = 900

The left side is the sum of all interior angles in the shape, and the right side is what the sum should be when expressed as a number.

4) We have to combine all like terms on the left side:

---> 10x + 10x + 9x + 12x + 10x = 51x

---> 9 + 133 + 14 -9+5+136 = 288    

5) This means that ---> 51x + 288 = 900

Subtract 288 from both sides  and get:

---> 51x = 612    (900-288 = 612)

Then divide by 51 from both sides and get:

---> x = 12     (612 ÷ 51 = 12)

Therefore b.12 is your answer.

One could be |x|<-2
This could be one since no matter what you put in for x, it will always be positive.
