In a paint factory, an old conveyer line has filled 12 barrels of paint, and is filling more at a rate of 4 barrels per minute. A worker just switched on a newer line that can fill 10 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How long will that take? How many barrels will each line have filled?

Answers

Answer 1

Answer:

Take 2 minutesEach line would have filled 20 barrels

Step-by-step explanation:

First line is filling at 4 barrels a minute and has already filled 12

Second line is filling at 10 barrels a minute.

Assume the time taken to be equal is x:

12 + 4x = 10x

12 = 10x - 4x

6x = 12

x = 12/6

x = 2 minutes

Each barrel would have filled:

= 10x

= 10 * 2

= 20 barrels

What is the 100th term in the sequence?

Answers

9514 1404 393

Answer:

  -190

Step-by-step explanation:

The n-th term of an arithmetic (linear) sequence is given by ...

  an = a1 +d(n -1)

where a1 is the first term (8) and d is the common difference. We note that each term is 2 less than the one before, so the common difference is -2.

  an = 8 -2(n -1)

Then the 100th term is ...

  a100 = 8 - 2(100 -1) = 8 -198 = -190

The 100th term is -190.

If (3a + 3b + 1) (3a + 3b - 1) = 80, then what is a + b?

Answers

Answer: a + b = 3 -        maybe

Step-by-step explanation:

( 3a + 3b + 1 )( 3a + 3b - 1 ) = 80

Expand

9a² + 9ab - 3a + 9ab + 9b² - 3b + 3a + 3b - 1 = 80

Simplify

9a² + 9b² + 18ab - 1 = 80

move the 1 over

9a² + 9b² + 18ab = 81

divide by 9

a² + b² + 2ab = 9

not really sure after this part

move the 2ab over

a² + b² = 9 - 2ab

square root both sides

a + b =  

simplify

a + b = 3 -
