The distance from the library to the post office is 5.25 miles. use the fact that one mile is approximately 1.61 kilometers to find the distance from the library to the post office in kilometers. round the distance to the nearest hundredth of a kilometer, if needed.

8.45 kilometers

Step-by-step explanation:

Given

The distance from library to post office = 5.25 miles

We are given that one mile is equal to 1.61 kilometers

So to find the distance from the library to post office in kilometers we have to multiply 5.25 with 1.61

So,

The distance from library to post office in kilometers = 5.25*1.61

8.4525

Rounding off to nearest hundredth

8.45 kilometers ..

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!

the answer is c.
