Answer:
11/20 cups left
Step-by-step explanation:
first, we need to convert 3/4 and 1/5 into fractions with common denominators
so we would have:
15/20 and 4/20
now we need to subtract the fractions to get the difference
so we would do:
15/20 - 4/20 = 11/20
and that's the answer
hope that helped
Well the answer is 12-14=%58=x
Answer:
Step-by-step explanation:
...
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
