Step-by-step explanation:
A property of a parallelogram is opposite angles are congruent, hence
(a)
∠PMN = ∠LON = 79°
(b)
∠NPM = 180° - (79 + 34)° = 180° - 113° (sum of angles in a triangle is 180 )
∠NPM = 67°
∠LPN = 180° - 67° ( straight angle ), hence
∠LPN = 113°
Step-by-step explanation:
If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.
1. 40-22=18
2.18/40=.45
3.45=45%
Its going to be 3/7 because 3 is the first number and 7 is the second
Answer:
and
Step-by-step explanation:
The equation of the isotope decay is:
14-Carbon has a half-life of 5568 years, the time constant of the isotope is:
The decay time is:
(There is no a year 0 in chronology).
Lastly, the relative amount is estimated by direct substitution:
LCD would be 18
8/9 = 16/18
2/3 = 12/18
1/9 = 2/18
