First off, if it's mixed, you'd want to convert it to "improper" first, and then do the division... say hmm - 3 and 1/7

the line over the decimal part is because is a "recurrent decimal", or repeating one.
The ladder makes a rectangle triangle with the floor and wall, the ladder is the hypothenuse. So we use Pythagoras theorem: <span>the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides
</span>So we have:
hyp^2 = wall^2 + floor^2
and plugging data in:
18^2 = wall^2 + 7^2
324 = wall^2 + 49
wall^2 = 275
<span>wall = 16.58

Answer: 2/5 is closer 1/2. and it is easy to find half of 7 mentally. Half of 7 is 3.5, so Martin gave away about 3.5 pounds away.
Answer:
Ratio = 
Step-by-step explanation:
Volume of Sphere is given by the formula:

Where
V is the volume
and
r is the radius
Original Volume, given r = 3, would be:

Increased snowball volume:
Radius increased 0.25 per second, he spent 4 seconds, so radius increase:
0.25 * 4 = 1 cm
New radius = 3 + 1 = 4 cm
New Volume would be:

Ratio of New Volume to Original would be:

This is the ratio for current volume to original volume.
Answer:
You have 3 + 2 + 2 which is the same as 7 on the other side.
Step-by-step explanation:
3 + 2 + 2 is 7
