Answer:
In order to find the slope of the line, find two points that are on the line and use the equation: m=(y2-y1)/(x2-x1). The 2 points should be whole numbers.
Answer:
2%
Step-by-step explanation:
20% takes 10 years to decay
To find per year decay, we divide the percentage by the number of years, so we get unit rate of years {per year]. Thus we have:
20%/10 = 2% per year
It's that simple.
Hence, the percentage by which the substance decays each year is 2%
Answer:
153 ways.
Step-by-step explanation:
The answer is the number of combinations of 2 from 18
= 18! / 2! (18-2)!
= 18! / 2! 16!
= 18*17*16! / 2! 16!
= 18 * 17 / 2*1
= 9 * 17
= 153 ways.
