Answer:
240 minutes
Step-by-step explanation:
If it's 40 minutes for just 5 papers, we need to figure how many minutes it would take to grade just 1. So you have to divide 40 by 5 which is 8. Then 8 time 30 which is 240.
Solve for w and l by using the system of equations.
2l=-2w+228
l=w+42
Substitute w+42 for l in the first equation.
2(w+42)=-2w+228
2w+84=-2w+228
4w=144
w=36
Now substitute 36 for w in any equation to get l=78.
To graph the equations, first make them equal l.
l=-w+114 and l=w+42 are your equations. You ca plug in values for w to plot points on the graph.
The units are always squared.
The area can be found when given the diameter by first finding the radius.
Circumference can be used to find area.
Answer:546.58
Because if u add it all together it gives u that answer
<em>11</em>
5 pound = 500 pence
500 pence/ 45 pence= 11.1111111
