Substitute the given number in your formula and solve for the remaining variable.
.. 300 = 100e^(0.7t)
.. 3 = e^(0.7t) . . . . . . . . . divide by 100
.. ln(3) = 0.7t . . . . . . . . . .take the natural logarithm
.. ln(3)/0.7 = t . . . . . . . . . divide by the coefficient of the variable
.. 1.6 = t
Selection B is appropriate.
All sides are equal in a square



One side of the square measures 7+6 = 13
Hence, side DC is 13 units
Answer:
2 hours and 24 minutes
Step-by-step explanation:
1/6 + 1/4 = 2/12 + 3/12 = 5/12
5/12 = 1/x
5/12x = 1
5x = 12
x = 2.4
2 hours, 24 minutes
Answer: x=6
Step-by-step explanation:
3(x-2)=12
3x-6=12
3x=18
x=6
