Sam estimates that it will cost \$16,000 to buy his son a car in 16 years. he currently has $5,500 to deposit in an account. what simple interest rate must his account have to reach a balance of $26,000 in 16 years?

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain

the answer is 3.54 g/cm^3

step-by-step explanation:

d=mass/volume therefore d= 46/13 which is a simple division equation.
