Answer: 99
Step-by-step explanation:
55/100 = 0.55
0.55 * 180 = 99
<h3>
Answer: b) 5 & 1/2</h3>
Work Shown:
Add the fractional portions
3/10 + 2/10 = (3+2)/10 = 5/10 = 1/2
To go from 5/10 to 1/2, you divide both parts by 5
The whole parts of the mixed numbers given add to 2+3 = 5
The whole parts add to 5, the fractional parts add to 1/2, giving us 5 & 1/2
They Started Off With 42/7 Instead Of 4/7
To solve a system of inequalities we graph both of them.
The inequality representing their combined pay would be

. This is because Jane makes 12.50/hr, Jack makes 10.00/hr, and they want to make at least, so greater than or equal to, $750 combined.
The inequality representing their combined hours working would be

, since they do not want their combined hours to be over 65. In both of these inequalities, <em>x</em> represents the number of hours Jane works and <em>y</em> represent the number of hours Jack works.
To graph these, we solve both of them for <em>y</em>:


The attached screenshot shows what the graph looks like. Going to the point where they intersect, we see that the shaded region that satisfies both inequalities begins when Jane works 40 hours and Jack works 25.
Answer:
Juan wins the race
Step-by-step explanation:
<u>The graph is shown in attached image.</u>
<u />
The black line is Juan's graph.
The green line is Antonio's graph.
The graph shows the distance (y-axis) with time (x-axis).
The end of the curve(s) means the end of the race. Both curve's ending point in y-axis is 4 miles so the end of the race is 4 miles.
But in x-axis, we see the time:
Juan finishes at 13 minutes
Antonio finishes at 15 minutes
<u>Definitely Juan wins the race</u>
