What is the 32nd term of the arithmetic sequence where<br> a1 = 14 and a13 = -58?
liq [111]
The nth term of an arithmetic sequence is found from:
n_{th}\ term=a+(n-1)d
Plugging in the given values, we get for the 13th term:
-58=14+12d
12d =-58 - 14 = -72
d = -6
So, the 32nd term is:
a_{32}=14+(32-1)-6=-172

85/100 is greater

85/100=.85 or 85%

21/25=.84 or 84%

.85 is greater than .84 so 85/100 > 21/25

The population of a city has decreased by 35% since it was last measured. If the current population is 9100 , what was the previ
Alina [70]

The previous population was 14000.

Explanation

The population decreased by 35% since the last measurement. So the current population is less than the previous population.

current population=9100

previous population =x

current population is 35% less than the previous population x

9100=x*(100-35)/100\\9100=(x*65)/100\\x=(100*9100)/65=14000

The previous population was 14000.
