Answer:

Step-by-step explanation:
Given




Required

This is calculated as:

Since it is a selection without replacement, the computation is:

So, we have:




Answer:
Length: meter
Mass: Kilogram
Volume of a solid: Cubic meter

The formula for calculating density:

The correct answer is #2: 6,2 9,3 12,4 because all of these answers equal 1/3
The area of only one base was added. The first term should have a factor of 2.
X/4 + x/5 = 1
5x/20 + 4x/20=1
9x/20 =1
9x = 20
x = 2.22 hours
