Step-by-step explanation:
The rate if increase of side of square is 7cm/s
dL/dt=7
At what area is the area increasing
dA/dt=?
Areas of square is give to be 36cm²
Analysis
Let L be the length of each side of the square, a square has equal side.
Area of square is give as L²
Area=L²
L²=36
i.e L=√36
L=6cm
Therefore at t=0 L=6cm and A=36cm²
A=L²
dA/dL=2L
Given that, dL/dt=7
Multiply the two differential together
dA/dt= dA/dL × dL/dt
dA/dt= 2L × 7
dA/dt= 2×6×7
dA/dt= 84cm²/s
The rate of increase of the square is 84cm²/s
6,272,640 square inches = 1 acre
10^6 square inches = 10^6/6,272,640 = 0.16 acre
0.16 acre = $12.50
2 acre = (2 x 12.50)/0.16 = $156.25
The cost coverifng 2 acres of land is $156.75
Answer:
$0.085 per mile or 8.5 cent per mile
Step-by-step explanation:
We know:
Total expenses = $1837
Gasoline expense = Total expenses - other expenses
= 1837 - 972 - 114 - 105 = $646
Benito drove in total of: 7600 miles
Cost of gasoline per mile = Money spent for gasoline / total miles
= $646 / 7600
= $0.085 per mile or 8.5 cent per mile
Hope this helped :3
Here are the following multiples:
59 * 2 = 118
and 118 * 1 = 118
The * means times.
