Answer:

Kate 55 hours

Dave 70 hours

Sarah 35 hours

Step-by-step explanation:

Let k be Kate's hours

Dave = 15 + k

Sarah = k- 20

Dave + Kate + Sarah = 160

15 + k + k + k - 20 = 160

3k - 5 = 160

3k = 165

k = 55

Kate worked 55 hours

Dave worked 70 hours

Sarah worked 35 hours

"Nya plans these steps before coding in a program.
Scrat [10]

The program would display "n = 3" as output based on Nya's steps.

<h3>What is a pseudocode?</h3>

A pseudocode simply refers to a description of the steps contained in an algorithm, especially through the use of a plain (natural) language.

<u>Note:</u> π is equal to 3.14.

Since Nya assigns π, which isn't an integer, the program would determine the integer (n) as follows:

x - 1 < n < x

π - 1 < n < π

Substituting the parameter (3.14) into the formula, we have;

3.14 - 1 < n < 3.14

2.14 < n < 3.14

n = 3.
