PLEASE HELP 85 POINTS A laboratory has a 75-gram sample of radioactive material. The half-life of the material is 10 days. (This means that it
takes 10 days for half of the initial mass to decay.)
The formula below can be used to find m, the remaining
mass in grams, in terms of t, the number of 10-day intervals
the mass has been decaying.
75(0.5)^t
Based on the formula, what is the mass of the laboratory's
sample remaining after 30 days?

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

5.25 ounces

step-by-step explanation:

divided 3/4 and 6
