Answer:

In these types of problems.....you wanna flip 4/10 to get its reciprocal, 10/4. After that, you will multiply 2 by 10/4. First, you multiply 2 times 10, which is 20, and then divide the answer by 4, which is 5. Hope this helped! :)

The population of two different villages is modeled by the equations shown

vlada-n [284]

Answer:

Year = 1995 and population = 315

Year = 2015 and population = 715

Step-by-step explanation:

It is given that the population of two different villages is modeled by the given equations:

$y=x^2-30x+540$

$y=20x+15$

The population of both villages are same after x years after 1980 if

$x^2-30x+540=20x+15$

$x^2-30x+540-20x-15=0$

$x^2-50x+525=0$

Splitting the middle term, we get

$x^2-15x-35x+525=0$

$x(x-15)-35(x-15)=0$

$(x-15)(x-35)=0$

$x=15,35$

It means, after 15 or 35 years, the population will same.

For x=15, years is $1980+15=1995$ and population is

$y=20(15)+15=315$

For x=35, years is $1980+35=2015$ and population is

$y=20(35)+15=715$ .

Therefore, population are equation in Year = 1995 and population = 315 or Year = 2015 and population = 715.

A spherical balloon has a circumference of 23 cm. What is the approximate surface area of the balloon to the nearest square cent

Bad White [126]

168cm2
Let r cm be the radius of the balloon, then
2pi(r)=23=>r=23/(2pi) 
The surface area= 
4pi(r^2)= 
4pi[23/2pi)]^2= 
(23^2)/pi=168.386 cm^2 
approximately.
