So set up the equations
q-12=d
25q+10d=1105
plug in q-12 as d in the second equation:
25q+10q-120=1105, then simplify:
35q=1225
q=35
since there's 12 fewer dimes, we know that there's 23 dimes and 35 quarters.

If the total amount of people serving as of January is estimated to be 1,400,000 people, how many are in the Air Force?
d1i1m1o1n [39]

Answer:

<em>There are 364,000 people in the Air Force.</em>

Step-by-step explanation:

<u>Percentages</u>

The N% of a number M is calculated by:

\displaystyle \frac{N*M}{100}

For example, 15% of 280 is

\displaystyle \frac{15*280}{100}=42

We know the total amount of people serving as of January is estimated to be 1,400,000 people and that 26% of them are serving in the Air Force.

Compute 26% of 1,400,000:

\displaystyle \frac{26*1,400,000}{100}=364,000

There are 364,000 people in the Air Force.

A certain radioactive material decays in such a way that the mass in kilograms remaining after t years is given by the function
Angelina_Jolie [31]

The mass of radioactive material remaining after 50 years would be 48.79 kilograms

<h3>How to determine the amount</h3>

It is important to note that half - life is the time it takes for the amount of a substance to reduce by half its original size.

Given the radioactive decay formula as

m(t)=120e−0.018t

Where

t= 50 years

m(t) is the remaining amount

Substitute the value of t

m(t) = 120e^-^0^.^0^1^8^(^5^0^)

m(t) = 120e^-^0^.^9

Find the exponential value

m(t) = 48.788399

m(t) = 48.79 kilograms to 2 decimal places

Thus, the mass of radioactive material remaining after 50 years would be 48.79 kilograms
