Answer:

The answer to your question is the letter B

Step-by-step explanation:

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 |

                                                | -4     7|

____ [38]

Answer:

For the .5s, go between the numbers for example, 4.5 is between 4 and 5 so you graph between them. Remember that the rule is (x,y) so graph the x (first number) on the horizontal line and graph the y (second number) on the vertical line.

Describe the dimensions of two different prisms that each have a volume of 2400 cubic centimeters using work
kirza4 [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

We have given the volume of a prism that is 2400 cubic centimeters.

we have not given which type of prism it is, so we are taking it as a rectangular prism.

The formula of volume of rectangular prism is :

Volume = l*w*h

Where l is length of base

w is width of base

h is height of prism

So,  2400=l*w*h

So, if we factor 2400 in two different manners, we could have two different dimensions of this prism having same volume that is 2400.

So, our first factor would be :

2400=20*20*6

Means the prism has base of 20 and 20 centimeters and height of 6 centimeters.

Our second factor would be :

2400=40*30*2

Means the prism has base of lenght 40 and width 30 and its height is 2 centimeters.

Hence we have two dimensions of prism, 20  20  6  and another one is 40  30  2.    :  Answer

Hope it will help :)

PLEASE help with number 5!!
LUCKY_DIMON [66]

Answer:

5/12

Step-by-step explanation:

1. Convert 1/4 to 3/12, then convert 1/3 to 4/12

2. Then add 3/12 and 4/12 together, which would be 7/12

3. Then subtract 12/12 by 7/12 which would be 5/12

                                         So, 5/12 is your answer.
