Step-by-step explanation:
white=26
1/4+1/8+1/12=6/24+3/24+2/24=11/24=(green,blue and yellow marbles)
24-11=13/24=white
26/13=2=1/24
blue=3/24
2.3=6
answer 6
Answer:
3.33
Step-by-step explanation:
Y=1/2x +0. You add the 2x to the other side, and then divide everything by 4 to have only 1y.
The given numbers are 13, 27, 81, 21,43, 48,23,39,45.
Square number is that number which is a perfect square means if you multiply a number by itself the number you obtained is a perfect square i.e it's square root is a natural number.
√13=not a natural number
√27=√3×√3×√3=3√3=irrational number
√81=√9×√9=9=a natural number
√21=not a natural number
√43=not a natural number
√48=4√3=not a natural number
√23=not a natural number
√39=not a natural number
√45=3√5=not a natural number
So, out of following numbers 13 27 81 21 43 48 23 39 45→81 is the only square number.
