Its 5 cuz you have to divide 20 by 4 and you get 5 (20÷4=5)
Ok well if you have 8 students and 2 boards divide the students by 2.
8/2=4
now, if each student wanted to paint part of a board and there are four students then divide 1 by 4
1/4=.25 or 1/4
so 4 students can paint one board while the other 4 students pain the other board
Answer:
3.45
Step-by-step explanation:
For solving of the area of a square pyramid, we can use the formula below:
A=a²+2a sqrt (a²/4 +h²)
where s for the slant height, r for the a/2, where a is the side length and h for the height
Substitute the values,
A=40²+(2*40) SQRT (40²/4 +21²)
A=3920
The answer is 3920 for the area of the square pyramid.
2: 3.45m
4: 10,000mm
6: 400cm
8: 3,000m
Hope this helps! (:
