Determine whether the point is a solution to the given system. You are going to explain your reasoning in the following question.
(True=a solution, False=not a solution)
(3, 4)
x + y = 7
y = 2x – 2
True
False

50- 250 is correct i did that one too

step-by-step explanation:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

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
