A Canadian television station shows 16 minutes of commercials every hour between 8:00 a.m. and 11:00 p.m. every day.
valentinak56 [21]

There are 16 minutes of commercials per hour from 8 A.M to 11 P.M

First, we have to find out how many hours is 8 A.M to 11 P.M

The hours are: 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11.

So, it is 16 hours from 8 A.M to 11 P.M

Then, we multiply multiply 16 by 16 to find out how many minutes of commercials are in 16 hours.

16 x 16 = 256

So, there is 256 minutes of commercials in 16 hours.

Lastly, multiply 256 by 365 to see how many minutes of commercials are in one year.

256 x 365 = 93,440

Therefore, there are 93,440 minutes of commercials in a year.

Solve the problem given below

<u>Answer</u>

<em>12 in by 12 in</em>

<u>Explanation</u>

The original length = x

This makes the length of the cube made to be = x - (2×2)

                                                                               = (x - 4) in

height of the cube = 2 in

Volume of the cube = (x - 4) × (x - 4) × 2 = 128

                                 = (x² - 8x + 16) × 2 = 128

                                = 2x² - 16x + 32 = 128

                                 = 2x² - 16x + 32- 128=0

                                 = 2x² - 16x - 96 = 0

                                 = x² - 8x - 48 = 0

lets use the factor method to solve the quadrilatic equation above,

x² - 8x - 48 = 0

proctuct = -48

sum = -8

The two factors are; -12 and 8.

(x + 8)(x - 12) = 0

So the value of x are 12 and -8.  Since x is a length, it can not be negative.

∴ x = 12 in.

The original dimensions of the sheet are <em>12 in by 12 in</em>.
