are you smarter than a 7th grader?

Question

if your smarter than me, you can figure this out.. give details and explanation. 10 points to hwho gets it right.


in 2000 the population of the united states was estimated to be 274700000. if the population grows by 1.1% per year, what would the population be in 2001? In 2002? in 2003? (round to nearest 1000 people).

haha i like the way you think frugernity, but no, thanks for trying

this is fun. dont think your doing all the work. actually i put the easier one of all my HW up. im doing the other 5 as you answer my question

Answer 1

Trivia?? Right!! Lucky for your homework I like math. ....

Alright, here goes...

2000 ... 274,700,000
2001 ... 274,700,000 + (274,700,000 x .011) = 277,722,000
2002 ... 277,722,000 + (277,722,000 x .011) = 280,777,000
2003 ... 280,777,000 + (280,777,000 x .011) = 283,866,000
...... (last year's pop) + (last year's pop x rate of growth) = pop

(pop=population)

To calculate a year's population based on the rate of growth... multiply the last year's population by the rate of growth and add that number to last year's population. You have your answer(s). The trick is knowing that you have to get the number for the change in population (last year's pop x rate of growth) before adding it to the last year's population.

Answer 2

The question should read: " what should the population have been in 2001, 2002, and 2003. Being that we are in 2007 at the present time.

Answer 3

To the nearest thousand, I get:

2001 = 277722000
2002 = 280777000
2003 = 283865000

However, these answers come without warranty and are not intended to suggest I am smarter than you, or any other 7th grader.

Moo's answer is the most elegant...but the most amusing part for me is discovering just how many of us can't do 7th grade math anymore.

Answer 4

Honey the thing is we have been doing much more complicated math so to answer such a easy question which only involves multiplication and dividing etc...would be a waste of time. Sorry but we aren't going to do your homework for you....now try to answer this. Whats ReTe + 8 =RwTw, Re=7, Rw=23, Te + Tw =60
find Te and Tw.
Here's another question...Paula ran to Hugo in 2 hours, while Busking walked the same distance in 72 hours.How fast did Paula run if her speed was 11 kilometers per hour faster that Busking's ? How far was it to hugo?

Answer 5

Is this your smart way of making us do your homework?
Next time just say please lol

In 2001: 274700000 x (1+1.1/100) = 277 721 700

In 2002: 277 721 700 x (1.011) = 280 776 638.7

I1n 2003: 283865181.7

To the neerest 1000:

In 2001: 277 721 000

In 2002: 280 777 000

In 2003: 283 865 000

Answer 6

Assuming you're looking for a logarithmic formula rather than a simple formula (as a logarithmic formula is, of course, more accurate):

Pe^(RT)=P sub n
where P=the population in 2000
R=rate (population increase per year)
T=time in years
e=(approximately) 2.71828
P sub n is the population for a given year

for 2001:

274700000*e^(0.011*1)=
277738000

for 2002:

274700000*e^(0.011*2)=
280810000

for 2003:

274700000*e^(0.011*3)=
283916000

Answer 7

2001 - Population 277,714,000
2002 - Population 280,789,000
2003 - Population 283,857,000

Take 2000 Population of 274,700,000 x 0.011 = 3,014,000, add to starting population, multiply that by 0.011. Repeat procedure until you get the population in year 2003, as above.

Answer 8

Good idea. I just had people help me wit my hw. Here ya go!

2001: 302170000 people.

2002: 332387000 people.

2003: 365625700

Answer 9

2001 it would be 24971700
my turn
give a set of parametric equations in which the slope of rise over run is -3/5

Answer 10

i do no longer think of so. yet seventh graders are no longer wealthy adequate to fund a marketing campaign in keeping with lies and manipulation and, a technique or the different, ruin out with it. money ought to influence the strategies. "much less government", says the seventh graders...wait...I forgot...all of us are for greater government now that we are in a "unexpected" financial disaster. with the help of how, there have been countless study that prepare, the greater knowledgeable you're, the greater you vote democrat. this is actual genuine...people who disagree ought to study up in this...in case you are able to study.
