If a system's instruction set consists of an 8-bit opcode, what is the maximum number of output signal lines required for the co

otez555 [7]

Answer:

D. 256

Explanation:

Given

$Instructions = 8\ bit$

Required

Determine the maximum number of output

To get the required value, we make use of the following:

$Maximum = 2^n$

Where n is the bits of the opcode.

i.e.

$n = 8$

Substitute 8 for n in $Maximum = 2^n$

$Maximum = 2^8$

$Maximum = 256$

<em>Hence, option D answers the question</em>

Yolanda is making a banner for a school pep rally. She cuts fabric in the shape of a parallelogram. The angle at the bottom left

Irina18 [472]

The answer is 100°

A parallelogram is any four sided shape with two pairs of opposite parallel and equal length sides. It is safe to say that a square is a parallelogram and not the other way round.

To explain how we got to 100 degrees, I have attached an image. Based on the image attached, the opposite angles are equal. The adjacent angles are supplementary. With this in mind, the supplement of 80° will be 100°
