Answer:
9
Step-by-step explanation:
it will take approximately (72 / 8) = 9 years to double the invested money.
Given that the situation has been modeled by the formula:
B=1000e^(kt)
given that B=8520 after t=15 min
then the value of k will be solved as follows:
plugging in the values in the formula and solving for k
8520=1000e^(15k)
8.52=e^(15k)
solving for k
15k=ln(8.52)
hence
k=ln(8.52)/15
k=0.1428
k=0.143
Answer:
The correct answer is option C.
Step-by-step explanation:
Length of shoe box = l = 11 inches
Width of the shoes box = w = 6 inches
Height of the shoe box = h = 5 inches
Wrapping paper required t cover the shoe box will be equal to the total surface area of the shoe box.
Shoe box = Cuboid
Total surface area of the cuboid = 2(lw+wh+hl)
Total surface area of shoe box : T


Frank will need 302 square inches of wrapping paper to cover the shoe box.
Subtract 6 from both sides
15x= 195
Divide both sides by 15
x=13
Final answer: x=13
Check:
15(13)+6
195+6
201
201=201
