Mathematics
1 answer:
Reil [10]2 years ago
7 0

Answer:

When c and a are positive or both are negative

Step-by-step explanation:

negative times negative equals positive so if a was negative and c was negative -a*-c= ac

Of course positive times positive equals negative so if a and c were positive we could do

a*c= ac

Hope I could help !

A city that had 8000 thousand people at the beginning of the year 2000 has been decreasing by 3.2% per year. What is the 1-year
Margaret [11]

Answer:

7,744 (96.8% of population at the beginning of the year)

Step-by-step explanation:

Population of the city at the beginning of the year = 8000people

Yearly percentage decrease = 3.2%

This means at the end of the first year the population reduces by 3.2% which gives 3.2%of 8000

= 3.2/100 × 8000

= 3.2 × 80

= 256

This shows that the population decreases by 256 at the end of first year.

To get the 1year percentage change in population, we will subtract the percentage decrease in Population from the initial population to give;

8000 - 256

= 7,744

7,744population remains after 1year wish is (100-3.2)% i.e 96.8% of the population at the beginning of the year.

The last number is in parenthesis because it's a negative: nevermind that for now.
What you want to do is 29-4.37 FIRST.
That gets you:
24.63. NOW you want to subtract the last number, because adding a negative = subtracting a positive.
24.63 - 5.68
