Explanation: The question is most likely asking what the arrow's pointing at, and it's right at the meeting point for lines x and y. Lines x and y would be the common ancestors of the point the arrow is showing since they're above the point and meet up to the point.
Answer:
age = 63.2 years
Explanation:
Given data
Number of years = 31
number of seconds = 1 billion
Age = ?
Solution
First we convert seconds to minutes
minutes = 1000000000 / 60
minutes = 16666666.667
Now convert minutes to hours
hours = 16666666.667 / 60
hours = 277777.778
Now convert hours to days
days = 277777.778 / 24
days = 11574.074
Now convert days to months
months = 11574.074 / 30
months = 385.802
Now convert months to years
years = 385.803 / 12
years = 32.15
Now add these years with given years
age = 31 + 32.15
age = 63.2 years
Metallic bonds are found in metals like zinc.
11×2=22
(11×2)+(6)+(8×3)=52
22/52=0.4230
0.4230×100=42.3%
