Answer
Find out the what fraction of the sandcastle did they build together .
To prove
Let us assume that the fraction of the sandcastle they build together be x .
As given
Than the equation becomes
L.C .M of (3,7) = 21
solving
Therefore the fraction of the sandcastle did they build together be
Hence proved
A histogram is like a bar graph without gaps between the rectangles. So you first create a bar graph with your labels and title, then you get rid of the gaps between the rectangles.
The answer:
just look at the attached file for finding explanation
Answer:
x = 12
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (6), x is a projection (x), and y is the other projection (3):
6 3
---- = -----
x 6
Cross multiply:
36 = 3x
12 = x
x = 12
