I fill an aquarium to a depth of 3/8 meters in 6 minutes. What is the unit rate in minutes per meter?
Elena L [17]

Answer:

16 minutes per meter

Step-by-step explanation:

Depth = 3/8 meters

Time taken = 6 minutes

What is the unit rate in minutes per meter?

Time taken per depth = minutes per meter

Unit rate in minutes per meter = 6 minutes ÷ 3/8 meters

= 6 minutes × 8/3 meters

= 48/3

= 16 minutes per meter

The statements A, B, D, and E are defined.

When we multiply matrices, the number of columns of the 1st matrix must equal the number of rows of the 2nd matrix.

<h3>What is the subtraction of the matrix?</h3>

When we add or subtract matrices, the number of rows and columns must be the same.

A) If C is 7x3 and A is 3x2, that means C has 3 columns and A has 3 rows. So C * A is defined.

B) When you transpose a matrix, the number of rows and columns are switched. So C^T has 3 rows and 7 columns. So C^T is defined.

C) B has 2 columns and C has 7 rows, so B * C is not defined.

D) Because A and B have the same number of rows and columns, we can add them. So A + B is defined.

E) B^T has 2 rows and 3 columns, and C^T has 3 rows and 7 columns. So B^T has the same number of columns as the number of rows as C^T. So B^T * C^T is defined.

F) C and A have different numbers of rows and columns, so C-A is not defined.
