The answer of the question that is 87 half is 43.5
1/2 of 87 =43.5
8.7 / 2 is equal to 4.35
43.5
Half of 174 is 87
87 and a half percent:87 1/2%= 87.5%= 0.875 in decimal= 875/1000 or 7/8 in fraction
87.5
175/2
16*87.5 = 1400
Half of 174 is 87
87 and a half percent:87 1/2%= 87.5%= 0.875 in decimal= 875/1000 or 7/8 in fraction
87.5
175/2
the answer is 43.5.
87
0.875
Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.
175/2
87 million years old
In my reference RB87 is stable, or has a half life of at least 4.9x1010 years.
Divide 4.6 billion by 5x1010 which is the half life of Rubidium 87, and you will have your answer.
