The population of a city this year [2018] is 34,500. The population is expected to grow by 2% each year. What will be the popula
Talja [164]
The answer would be A. 39,300.

I got this by multiplying 34,500 by 2% and getting 690. Since 2018 is 7 years away from 2025, I multiplied 690 by 7 getting 4,830. I added the 4,830 to the original population of 34,500 and got my answer, 39,300. Hope I helped!

Match the fraction with its equivalent decimal form of the number.
bagirrra123 [75]

Answer:

  see below

Step-by-step explanation:

The overbar on decimal digits means they repeat forever.

Any fraction with a denominator consisting of powers of 2 and/or 5 will terminate. These can be converted to decimal by multiplying the fraction by a number to make the denominator an appropriate power of ten.

  1 2/3 = 1.66666666666... repeating

  1 3/5 = 1 (3·2)/(5·2) = 1 6/10 = 1.6

  1 1/4 = 1 (1·25)/(4·25) = 1 25/100 = 1.25

  1 33/50 = 1 (33·2)/(50·2) = 1 66/100 = 1.66

Of course, your calculator can tell you the decimal equivalents, too.

During a certain week, a post office sold Rs.280 worth of 14-paisas stamps. How many of these stamps did they sell?
Novosadov [1.4K]
So basically ...

You convert the rupees in paisas. One rupee is equal to one hundred paisas, so ...

280 × 100 = 28,000

And then we divide,

28,000 ÷ 14 = 2000

The post office sold 2000 stamps!

Hope this helped! :)
