The population of a country increased by an average of 2% per year from 2000 to 2003. If the population of this country was 2 000 000 on December 31, 2003, then the population of this country on January 1, 2000, to the nearest thousand would have been

Answers

Answer 1

Answer: The population as grown 2% per year for 3 years. Therefore the country has grown by 6%.

First I would find out 10% of the population, which is 200,000. Therefore 5% would be 100,000. 1% would be 20,000. Add 5% and 1% which is 120,000.

Finally take away 120,000 from 2,000,000 which is 1,880,000. Therefore the population in 2000 would of been 1,880,000

The natural numbers are presumed to have started before recorded history when humans began to count things. The Babylonians developed a place-value system based on the numerals for 1 (one) and 10 (ten). The ancient Egyptians added to this system to include all the powers of 10 up to one million.

Andre received $60 for his birthday and put it in his piggy bank. Each week, he puts 3 more dollars in his bank. The amount of money in dollars D in his bank is given by D = 3w + 60, where w is the number of weeks he has saved 3 dollars. His sister Lana makes a table of reasonable values for w. Lana selects 12 as a value for w. What is the corresponding table entry for D?

A.
372

B.
96

C.
75

D.
64

Answers

96 → B

substitute w = 12 into the equation D = 3w + 60

D = (3 × 12 ) + 60 = 36 + 60 = 96

Step-by-step explanation:

One person can do a certain job in ten minutes, and another person can do the same job in fifteen minutes. How many minutes will they take to do the job together? If x represents how many minutes to do the job together, then how much of the job does the slowest person do?

1. x/15
2. x/10
3. 15/x

Answers

Together they can complete the whole job in 6 minutes.

The amount of work done by the slowest person is $(x)/(15)$ .

What is time, work done, and rate formula?

The time, work and rate formula is given by

Work done = time × rate of wok

According to the given question.

One person can do a certain job is 10 minutes.

⇒ The work done in 1 minute by the first person or the rate of work done by the first person = $(1)/(10)$

Another person can do the same job in 15 minutes.

⇒ The work done in 15 minutes by another person or the rate of work done by the second person = $(1)/(15)$

So,

The amount of work done by both of them in one minute

= $(1)/(10) + (1)/(15) =(1)/(6)$

⇒ Together they can complete the $(1)/(6)$ th part of the work in one minute.

Therefore, together they can complete the whole job in 6 minutes.

As, we know that

Work done = Total time taken × Rate of work done

Since, the second person is taking 15 minutes to complete the jo.

So, he is the slowest person.

Total time total time taken by the two persons to complete the job together is x (given).

Also, the rate of work done by the slowest person = $(1)/(15)$

Therefore,

The amount of work done by the slowest person = $x ((1)/(15) )$

Hence, the amount of work done by the slowest person is $(x)/(15)$ .
