A sample of a radioactive isotope had an initial mass of 330 mg in the year 1990 and decays exponentially over time. A measurement in the year 1995 found that the sample's mass had decayed to 160 mg. What would be the expected mass of the sample in the year 2003, to the nearest whole number?

because its not ur topic and its not for is for homework not that.

your answer is a

step-by-step explanation:

plzplzplzplzplz mark brainliest i need it.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
