Lowest common multiple of 40 and 220

Answers

Answer:

440

Step-by-step explanation:

Prime factors of 40 = 2 x 2 x 2 x 5

Prime factors of 220 = 2 x 2 x 5 x 11

Common factors = 2² x 5

Prime factors of 40 (excluding common factors with 220) = 2

Prime factors of 220 (excluding common factors with 40) = 11

Multiply the common factors with remaining factors

2² x 5 x 2 x 11

= 440

If 2x+z=2y and 2x+2y+z=20 what is the value of y?

Answers

$2x+z=2y\to2x=2y-z\n\nsubstitute\ to\ 2x+2y+z=20:\n\n(2y-z)+2y+z=20\n2y-z+2y+z=20\n4y=20\ \ \ \ /:4\ny=5\to answer$

The value of y is 5

Given,

2x+z=2y

2x+2y+z=20

Now,

From equation substitute the value of 2x,

2x = 2y -z

substitute the value in second equation,

2y -z + 2y + z = 20

Now solve the terms with like variables,

4y = 20

y = 5

A culture started with 2000 bacteria. After 2 hours it few to 2200 bacteria. Predict how many bacteria will be present after 19 hours.

Answers

Answer:

3900 bacteria will be present

Step-by-step explanation:

A culture started with 2000 bacteria and after 2 hours it grew to 2200 bacteria, determining the rate, we can assume that for every hour, 100 bacteria adds onto the culture. Therefore:

If 19 hours have passed, multiply 100 by 19 to insinuate the every hour per 100 bacteria.

19 * 100

1900

Now you can add this to the original starting bacteria:

2000 + 1900

3900 bacteria
