So it cooks for 2 hrs and 20 minutes......and it has to be done by 1 pm.
so from 1 p.m. - 2 hrs = 11 a.m........- 20 minutes = 10:40 a.m
start cooking at 10:40 a.m. and it will be done by 1 p.m
Jan Quint earned $542.5 last week.
If she worked 40 regular hours than we must multiply 40 by 7.
40 * $7.00 = $280
Now we need to find how much she earned for her 9 hours of overtime. For overtime she gets paid her normal pay plus half of her normal pay. So $7 + $3.5 = $10.5 So for each hour of overtime she gets paid $10.5
9 * $10.5 = $94.5
Next we need to find out how much she earned for her 12 hours of holiday time. She gets paid double for holiday time which is $7*2 = $14. So for each hour of holiday time she gets paid $14
12 * $14 = $168
Lastly we need to add all those earnings together to find out how much she earned that whole week with verything included.
$280 + $94.5 + $168 = $542.5
For dividing fractions you should always use the KCF method: Keep Change Flip
6/10 divided by 12/7
Kcf method:
6/10*7/12= 42/120
42/120 in simplest form will be 7/20
So the answer is A
The slope of a line parallel to this line is -4/7
And the slope of a line perpendicular is 3/4
