Answer:
B
Step-by-step explanation:
well by rotating ΔABC by 60*(degrees) about A , such that in ΔA'B'C,B =C'
you can see that ΔAPP' is equilateral side length 1, meaning that <APP' =60*
you can also see that ΔCPP' is a 30- 60- 90 right angle also meaning that <CPP' =60* now,by adding the two together you see that < ACP =120* now you can also use the law of cosins and soooo
s2=(AP)2+(CP)2-2(AP)(CP)cos120*
s2=1+4-2(1)(2)cos120*
s2=5-4 (-1over2)
s=
7
so b is your answer hope this helped

Step-by-step explanation:
Given fractions ,
,
.
We need to list them from least to greatest.
In order to arrange them from least to greatest, we need to find the least common denominator of ,
,
.
We have 3, 6 and 5 in denominators.
Least common multiple of 3, 6 and 5 is = 30, because 30 is least number that can be divided by all three number 3, 6 and 5.
Let us covert each denominator as 30.
Multiplying first fraction by 10 in top and bottom, we get
Multiplying first fraction by 5 in top and bottom, we get
Multiplying first fraction by 6 in top and bottom, we get
Now, we can check
is the smallest,
is greater and
is the greatest.
Therefore, we can arrange fractions
Writing original fractions in place of equivalent fractions, we can write
,
and
.
Therefore, the order the amounts of paint from least to greatest is:
,
