In a biology lab, 500 bacteria reproduce by splitting. Every hour, on the hour, each bacterium splits into two bacteria.

Answers

Answer:hour 1 500, hour 2 1000, hour 3 2000 , hour 4 4000

Step-by-step explanation:

After 1 hour 500 bacteria split into 500 bacteria.

After 2 hour 500 bacteria split into 1000 bacteria.

After 3 hour 500 bacteria split into 1500 bacteria.

After 4 hour 500 bacteria split into 2000 bacteria.

Given that,

In a biology lab, 500 bacteria reproduce by splitting.

Every hour, on the hour, each bacterium splits into two bacteria.

We have to find,

Find the number of bacteria after 4 hours.

According to the question,

Let us assume n = the number of bacteria at a given hour.

Total number of bacteria = 500

At the end of 1 hour each of the 500 bacteria after an hour is split in to 2 bacteria. So, at the end of 1 hour = n(1)  = 1 × 500 = 500 After 1 hour 500 bacteria split into 500 bacteria.

At the end of the 2 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(2)  = 2 x 500  = 1000 bacteria After 2 hour 500 bacteria split into 1000 bacteria.

At the end of the 3 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(3)  = 500 x 3  = 1500 bacteria After 3 hour 500 bacteria split into 1500 bacteria.

At the end of 4 hours, each of the 500 bacteria spilt into 2 more bacteria.

       So,  n(4)  = 4 × 500 = 2000 bacteria

       After 4 hour 500 bacteria split into 2000 bacteria.

Answer:

1. 8x + 3y - x - 2y

= 8x - x + 3y - 2y

= 7x + y

2. 3n - 7n - 2n + x + 8x

= 3n - 9n + 9x

= - 6n + 9x

3. 2r - 5n + 9y - 3r + n

= 2r - 3r - 5n + n + 9y

= -r - 4n + 9y

4. 12y - 6x + 5y - 3n

= 12y + 5y - 6x - 3n

= 17y - 9n

5. - 13n + 4n - r

= -9n - r

6. 7xy - 8x + 6xy - y

= 7xy + 6xy - 8x - y

= 13xy - 8x - y

7. - 14r - 10n - 3r - 9n

= -14r - 3r - 10n - 9n

= - 17r - 19n

8. 6r + 9r - 2r - 13n

= 6r + 7r - 13n

= 13r - 13n

9. n + r + x - 3x +4r

10. 15y - 7x + 9z + 4z - 3x
