400*125=50000
50000*30=1500000
so the santas see 1500000 childeren in 30 days
Answer:
N/m^2
Step-by-step explanation:
If the amount of force (newtons) is changing over the surface area, that means we should use units in the form of newtons over surface area, which is in the form of m^2.
Answer:
40%
Step-by-step explanation:
First, divide 100 by 20. You do this because you need something out of 100 to equal a percent. (Example- 50 out of 100 is 50%)
Next you need to take the number you got from dividing (5) and multiply that with 8. This leaves you with 40/100 or 40%.
Hope this helps!

Volume is a three-dimensional scalar quantity. The volume of concrete that will have to be poured into the pool deck is 6.0185 cubic yards.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Since an inch is equal to 1/12 of a foot. Therefore, the thickness of the pool deck is,
3 inches = 0.25 foot
If a pool deck of 650 square feet is to be laid with concrete 3" thick, then the volume of concrete that will be needed is,
Volume of concrete = 650 ft² × 0.25 ft = 162.5 ft³
Now, one yard is equal to 3 feet, therefore,
1 cubic foot = 1/27 cubic yards
162.5 cubic feet = 6.0185 cubic yards
Hence, the volume of concrete that will have to be poured into the pool deck is 6.0185 cubic yards.
