Answer:

The average density of the rod is 1.11 kg/m

Step-by-step explanation:

Linear density is given by the expression 10/(sqrt(x 1)) kg/m

x is said to be measured in meters from one end of the rod. Therefore x represents the length of the rod = 8 m

Substitute the value of x into the expression of linear density to determine the average density of the rod

Average density = 10/(sqrt(81)) = 10/9 = 1.11 kg/m

What is greater 3 x 1/10 plus 4 x 1/100 plus 8x 1/1000 greater than one and two tenths
Elena L [17]
So, first let's change these numbers into decimal form:
3*0.1 + 4*0.01 + 8*0.001 ? 1.2
Multiply:
0.3 + 0.04 + 0.008 ? 1.2
0.348 < 1.2
One and two tenths is larger.
Hopefully this is what you're asking, as this question is unclear

I need help on how to solve this equation C+(4-3c)-2=0 stp by step
Mumz [18]
Step 1-  Simplify brackets 
c + 4 - 3c -2 = 0
Step 2- Simplify c + 4 - 3c -2 to -2c + 4 - 2
-2c + 4 - 2 = 0
Step 3- Simplify -2c + 4 - 2 to 2c + 2
-2c + 2 = 0
Step 4- Subtract 2 from both sides 
-2c = -2
Step 5- Divide both sides by -2
Answer: c = 1

daser333 [38]

Answer: plane

A plane can be thought of a sheet of paper with no thickness, and this sheet does not bend or curve. A plane extends infinitely in all directions. Think of a perfectly flat floor that goes on forever.
