418.953 rounding to the nearest hundred

400

Step-by-step explanation:

rounding to the nearest hundred, in bold you'll see the hundred place.

418.953

The number next to that (right side →) determines if it stays 4 or goes one number up, 5.

If it's 4 or lower is stays the same

and

If it's 5 or higher (up to 9) it increases by 1.

so

because the number next to it is a 1, it stays 4.

Therefore 400 is the answer.

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!

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
