Answer:
Step-by-step explanation:
To calculate Workdone we're going to use the formula:
where F = ma, and a = g = 9.81 ms^-2
m = 2.2 kg
g = 9.81
only the vertical displacement from the original position (i.e the floor) is important when it comes to calculating Workdone. So, she <u>lifts</u> the books 1.25m from the floor and she puts the books in the shelf which is 0.35m above the floor.
So the net distance (or displacement) from the floor is: 0.35m
hence d = 0.35m
Plugging all the values in the equation will yield:
To convert fractions to decimals, divide the denominator into the numerator
3/9= .333333
123/999=.123123

Answer:
$43.20
Step-by-step explanation:
A swimsuit that originally cost $90 before any discount is on sale for 20% off.
X = price of swimsuit
X = 90
20% off = 90 * 0.8 = 72
The swimsuit is then put on clearance for an additional 40 % off the sale price.
72 * 0.6 = 43.2
what is the final price?
$43.20
