If the population of a town grew 15% up to 76,894, what was the population lest year?
frozen [14]
Let's first find the equation to find what the population went up to. X, will be the population of last year.
1.15x=76,894
Now, we need x by itself, so we need to divide both sides by 1.15.
76,894÷1.15≈66,864
There are decimals, but for this problem, hae .3478 of a person would not fit.
We can check our answer.
66,864×.15=10,029.6
10,029.6+66,864=76,893.6 (rounds up to 76,864)
So the population of the town last year was about 66,864 (66,864.3478) people.

PLEASE HELP!! point a= (3,2) point b=(27,30) point c is between point a and b what is c's coordinates
Yuki888 [10]

Answer:

let c is a point between a and b we can find the coordinates of c by using mid-point formula

the coordinate x of c is equal to

x=(x1+x2)÷2

x=(3+27)÷2

x=30÷2

x=15

the coordinate y of c is equal to

y=(y1+y2)÷2

y=(2+30)÷2

y=32÷2

y=16

so the coordinates of c are (15,16)
