5.0007. Five and seven ten thousandths
the population of a town is 80000
rate 4%
year(t)=2 year
80000*104/100*104/100=86528
the population of the town end of two year is 86528
Answer:
The positive sums are:
B. 5 + (–2)
C. –3 + 4
E. –2 + 4
Step-by-step explanation:
We can simply observe the sums to conclude that the sum will be positive or negative.
A. –5 + (–2)
We can see that both numbers are negative, the sum of two nu=egative numbers is also negative.
-5+(-2) = -5-2 = -7
B. 5 + (–2)
The number with greater magnitude is positive so the sum will also be positive.
5 + (–2) = 5-2 = 3
C. –3 + 4
The number with greater magnitude is positive so the sum will also be positive.
-3+4 = 1
D. 0 + (–3)
The number with greater magnitude is negative so the sum will also be negative.
= 0-3 = -3
E. –2 + 4
The number with greater magnitude is positive so the sum will also be positive.
-2+4 = 2
Hence,
The positive sums are:
B. 5 + (–2)
C. –3 + 4
E. –2 + 4
You know that it decreased 42 feet a second, so all you have to do is multiply by 27 to get 1134 feet. Since it's decreasing, it would be represented as a negative number, making the answer D. Next time, take it slow and draw a unit rate, as shown below!
