Answer:
Don't quit! You can work your way back up again! You should challenge yourself to make it back up!
Step-by-step explanation:
But I hope you're having a okay day/night and know you're worth it no matter what!
Luke earned $54 for 3 lawns
So each lawn = $54/3 = $18
After mowing 7 lawns =
7 X $18 = $126
A linear approximation to the error in volume can be written as
... ∆V = (∂V/∂d)·∆d + (∂V/∂h)·∆h
For V=(π/4)·d²·h, this is
... ∆V = 2·(π/4)·d·h·∆d + (π/4)·d²·∆h
Using ∆d = 0.05d and ∆h = 0.05h, this becomes
... ∆V = (π/4)·d²·h·(2·0.05 + 0.05) = 0.15·V
The nominal volume is
... V = (π/4)·d²·h = (π/4)·(2.2 m)²·(6.8 m) = 25.849 m³
Then the maximum error in volume is
... 0.15V = 0.15·25.849 m³ ≈ 3.877 m³
_____
Essentially, the error percentage is multiplied by the exponent of the associated variable. Then these products are added to get the maximum error percentage.
Answer:
64 square units
Step-by-step explanation:
Split the figure into 2 rectangles of dimensions:
4 × 10
8 × 3
And solve.
(4 × 10) + (8 × 3) = 40 + 24 = 64 square units
See the attached image for a model.
