Harriet works 42 hours a week. She gets paid £9.12 for each hour she works. An estimated amount Harriet gets paid in a week is £378
<h3>How to calculate the percent error?</h3>
Ssuppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
Harriet works 42 hours a week. She gets paid £9.12 for each hour she works.
1 hour = £9.12
Estimated
£9 x 42 hours = 378
Actual
£9.12 x 42 hours = 383.04

Answer:
225 minutes or 3 hours and 45 minutes
Step-by-step explanation:
45 (minutes per day) times 5 (days in a school week) = 225 minutes
or add 45 (minutes per day)+ 45+45+45+45 = 225
To get the hours:
Divide 225 by 60 (minutes per hour) and it is 3 - remainder 45.
Answer:
Surface Area is 56π cm²
Step-by-step explanation:
The area for a cylinder's surface area is
a=2πrh+2πr²
The cylinder base's radius is 4 cm
The cylinder's height is 3 cm
Putting into the equation:
a=2×π×4×3+2×π×4²
a=2π×4×3+2×π×4²
a=8π×3+2×π×4²
a=24π+2×π×4²
a=24π+2×π×16
a=24π+2π×16
a=24π+32π
a=56π
The surface area of the cylinder is 56π cm².
Answer: Probably A
Step-by-step explanation: You need to use a ruler for this, because without one its impossible to get it exact
Using the ruler though, you'd measure each side of the wall and either use a ratio of 0.5in:4ft or multiply every 0.5in by 4ft.
