A cardboard sheet is cut in the shape of a triangle, with vertices at (0,0), (20,0), and (3,4) units. the thickness of the sheet
kenny6666 [7]
This problem can be solved in two ways, the long way, or the short way.

1. The long way
We know that the base of the triangle is along the x-axis, and the length of the base is 20.
The centre of mass is located at 2/3 of the distance from vertex (3,4) along the median, which cuts the base at (10,0).
Therefore the centre of mass is located at
x=3+(10-3)*2/3=23/3
y=4/3

2. The short way
It turns out that the centre of mass of a triangle sheet is located at the mean of the coordinates of the three vertices, i.e.
CG=((0+20+3)/3, (0+0+4)/3)=(23/3, 4/3)  as before.

The sum of 13 divided by a number and that number divided by 13
7nadin3 [17]
Sum means add

the number is x

13 divided by a number is 13/x
the number divided by the number is x/13


so
\frac{13}{x}+\frac{x}{13}
also can be simplified to
\frac{169}{13x}+\frac{x^2}{13x} or
\frac{x62+169}{13x}



translated it is \frac{13}{x}+\frac{x}{13} where x is the number

What fraction has a decimal value between 1/2 and 3/4
andreyandreev [35.5K]
To find the decimal value, we must convert 1/2 and 3/4 into decimal.
1/2=0.5
3/4=0.75
Now we just have choose a random decimal in between the decimal.
Let's choose 0.6
Now we have to convert the decimal into a fraction. So we'll multiply the decimal by100.
0.6×100=60
Then we make the 60 into a fractions. 60/100
Then we'll simply the fraction. 60/100÷10=6/10÷2=3/5
There you go. You have your answer.
