The population of a small town in 1990 was 1,200 people, and the population in 2000 was 2,700 people. Let x represent the number

of years since 1990. Let y represent the population. Which linear equation represents this data?

Well... looking at how to question is defining things.....i think this is a multiple choice question.....

Given:
"y" represents the population
"x" represents the number of years
duration = 2000 - 1990 = 10 years
population increase = 2700 - 1200 = 1500
Now,
<u></u><u>It says linear equation........</u><u>, So, we have to assume that every ten years the population increases by a fixed </u><u>amount that is 1500 people every 10 years.</u><u />

Now, 
Every 10 years, the population increases by 1500
Every 1 year , the population increases by 1500 / 10 
                                                               = 150

Now,
The equation in determining the population is:

y = 150x + 1200

<span>If you have a $460,000 loan at 6% interest for 25 years; payments should be $2,963.79, not $2962.40. At $2,963.79, $2,300 would be interest, $663.79 would be principal. After that first payment your balance would be $459,336.21.

Please help urgent!!! Find the value of x in the triangle shown below!
qwelly [4]

Answer:

Step-by-step explanation:

so we know a few things about t his triangle,  it's a special one  :P  ,   it's called isosceles because  two of the legs are the same length, which also mean that the angle x  is the same at the other unknown angle sooo  there are  2 x's   if that makes sense?  and then we can solve this , b/c we also know that the interior angles of a triangle add up to 180°

180 = 32 + 2x

148 = 2x

74 =x

∠x = 74°

What is the circumference of a circle with a radius of 2.5 meters?
Hitman42 [59]

Answer:

15.71m

Step-by-step explanation:

circumference of a circle = 2πr

where r = 2.5m

where π = 3.142

we have,

2*3.142*2.5 = 15.71m

therefore the circumference of a circle with a radius 2.5m = 15.71 m

8 people eat at Charlie Brown's for Thanksgiving. How many different seating
never [62]

Answer: 40,320

Step-by-step explanation: Let's say that there is person A,B,C,D,E,F,G,H. and 8 chairs. For the first chair, 8 different people could potentially sit in it, making 8 different possibilities. No matter who sits there, the logic follows the next table. However, since one person is sitting in the first chair, there are 7 different possibilities about who would be sitting in the second chair. If you multiply the two together, there are 56 different possibilities just for the first and second chair. For the third chair, there are 6 different possibilities about whom could sit. Multiply 56*6 and you get 336 possibilities. Keep multiplying out and you get a grand total of 40,320 different arrangements!
