The work done has the formula
W = F d
where the force and the displacement have the same direction
We can determine displacement using the distance formula
d = √[(5 - 0)² + (-1 - 4)²]
d = 5√2
Next, the force along the direction of the displacement must be determined
Use trigonometry to determine the angle θ
Finally, the work is calculated using the formula
W = F d / cos θ
substitute the values to get the answer
Sarah's income = Number of trays × Rate per tray
y = 450 × 8
If there is an increase of 0.85 in price,
New price = 8 + 0.85
For x number of increases,
new price = 8 + 0.85x.
Number of trays reduced = 450 - 15x.
So, Sarah's income in this case is y = (450 - 15x) (8 + 0.85x).
Answer:
Step 1: Fill three gallon jug
Step 2: Pour the water from the three gallon to the five gallon jug
Step 3: Refill three gallon jug
Step 4: Pour three gallon jug into five jug until full (this leaves one gallon in the three gallon tank.
Step 5: Dump out the water in the five gallon jug
Step 6: Pour the 1 gallon of water into the five gallon jug
Step 7: Refill the 3 gallon jug
Step 8: Pour the 3 gallons into the five gallon jug (3 + 1 = 4)
Step 9: Place jug on scale.
Hope this helps!
I'm pretty sure it a 3 to 8 and 32 to 12
