To find out what fraction of the half quart each friend will get, divide the 1/2 quart into 2 groups.
1/2 divided by 2 is the same as 1/2 x 1/2 or 1/4 quart.
Each friend will get 1/4 quart of milk.
Step-by-step explanation:
Scatter plots are dots scattered all over the graph. I think that this is the easiest graph because all you need to do is put a dot where you want it.
A scatter plot doesn't need any lines, all it needs is dots.
Simple proportions.
You want a 1:5 ratio.
You have a 5:1 ratio.
So you add another 24 drops of white.
5:25 = 1:5
or
5/x = 1/5 and cross multiply.
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
4 = 400/100
or 400 hundreths
