A barista averages making 16 coffees per hour. At this rate, how many hours will it take until she's made 1,200 coffees?

Answers

Answer 1
Answer: 16 times x=1200 or 
16x=1200
divide both sides by 16
1200/16
so we  simplify 1200/16 by factoring out the ones (4/8=1/2 times 4/4 since 4/4=1)
1200=3*2*2*2*2*5*5
16=2*2*2*2*1
so we notice that there are four 2's in both so those are the 'ones' so cross them off and get
3*5*5/1 or 75/1 or 75 hours 
Answer 2
Answer: 75 hours
1200 coffees/16 coffees= 75 hours

Triangle inequality theorem-are the lengths 7, 4, and 2 of a triangle possible?

Answers


You can't make a triangle with those lengths for sides.

The way I look at it is like this:

-- Take  2  sticks ... lengths  4  and  2  ... and connect them together at one end.

-- The farthest they can reach, if they're opened up completely and pointing
in opposite directions, is a distance of  6 .

-- They can't reach the ends of a stick that is  7  long.  So you can't make
a triangle with those  3  sticks.


Answer:

YES!!!!!

Step-by-step explanation:

BASICS:

Pythagorean Theorem a^(2) +b^(2) = c^(2)

SETTING IT UP:

The smallest numbers are A and B.

4^(2) +2^(2) =7^(2)

SIMPLIFY:

16+4=21

This is not true, but we know that its OK because the answer is greater than the equation.

Data

                 | 5  0 |   | 2  - 1 |

                 | 3 -5 |   | 2  - 2|

Process

1.- This is the product of two matrices 2 x 2 so the result will be a 2 x 2 matrix.

- Multiply the first row of the first matrix by the first column of the second matrix.

-Multiply the first row of the first matrix by the second column of the second matrix.

- Multiply the second row of the first matrix by the first column of the second matrix.

-Multiply the second row of the first matrix by the second column of the second matrix.

                 | 5  0 |   | 2  - 1 |         | (5 x 2) + (0 x 2)    (5 x -1) + (0 x -2) |

                 | 3 -5 |   | 2  - 2|    =   | (3 x 2) + (-5 x 2)   (3 x -1)  + (-5 x -2)|

                                              =  | 10 + 0    -5 + 0 |

                                                  | 6 - 10     -3 + 10|

                                             = | 10  - 5 |

How do you subtract 9-3 7/8?

Answers

you take 9 times 8 which is 72out of 9 and subtract 3 which is 7 and 7/8 out of 7 is 6 and 1/8
Since 1-7/8=1/8, you have to also subtract 9-3=6. But since there is a fraction, you have to take away and extra one since if it was six it would be too big if you tried to add it back to 3&7/8. It would equal out to 10, so the answer is 5&1/8. If you add that up it equals 9.
