Answer:
12.5
Step-by-step explanation:
mean is where u add them then divide it by how many there are
6+8+10+12+14+15+15+20=100
100 divided by 8
When we make a solution, the solute doesn't go away. All the solute we use stays in the solution it only dissolve in the solution.
The total mass of solution is always equal to the mass of solvent added to the mass of solute.
Therefore 5gram + 20 gram = 25 gram of solution.
5/25×100= 20%
8 21/40
341/40
852.5/100
8.525
Hope this helps :)
Because a rectangle has four sides and the opposite sides are the same length, you can simply multiply each of the given sides (5 5/8 feet and 6 1/4 feet) by 2, and then add them together.
5 5/8 × 2 = 11 1/4.
6 1/4 × 2 = 12 1/2
11 1/4 + 12 1/2 = 23 3/4 or 23.75
Therefore, the perimeter of the rectangle is 23.75 feet.
