Answer:
According to the model, in 2025 the world population will be 8,493,750,000
Step-by-step explanation:
Rate at which population was growing per year = 0.09125 billion
Initial population figure in 1990 = 5.3 billion
World population prediction in 2010 ;
Predicted population figure :
Initial population + (population growth value per year * number of years)
number of years = (2025 - 1990) = 35 years
Predicted population figure in 2025 :
5.3 + (0.09125 * 35)
5.3 + 3.19375
= 8.49375 billion.
8,493,750,000 by 2025
The answer is A, 8.94 seconds.
Since Gary ran 0.93 seconds faster than Brian, his time will have 0.93 seconds more than Brian's. To figure out Brian's time you have to subtract these 0.93 seconds from Gary's time.
9.87 - 0.93 = 8.94
