a spool holds 6.75 meters and a craft club buys 21 spools. what is the total cost if the ribbons costs 2 dollars per meter?

1 answer:

3 0

● To do this, you need to multiply 6.75 by 21 to find out how many meters are in all. 6.75×21 is 141.75

● Next you multiply 141.75 by 2 to see how much it costs which is 283.5

● Since we're dealing with money, it would have two place values so we add a zero and we get $283.50

Assume a color display using 8 bits for each of the primary colors (red, green, blue) per pixel and a frame size of 1280 × 1024.

-8bits is equivalent yo 1 byte

-bit is(0 or 1)

So each pixel requires 3 bytes

Primary colors are RGB(red,green and blue),so each color represent one byte.

The frame size is:

1280×1024=1310720 pixels

So that the frame contained 1310720 pixels

The size of the frame buffer is equal to the product of RGB and frame pixels:

=3 × 1310720
