Answer:
she will be taking 3600 mgs. in 90 days
Step-by-step explanation:
if she is taking a 20 mgs. twice a day that will make it 40 mgs. a day. If she takes it for 90 days
you will multiply 90 by 40
so
90
x40
= 3600 mgs. in 90 days
check your calculator for the [!] factorial button.
also bear in mind that most calculators also have an [ₙPᵣ] button, to get Permuations, and you can just use that.
Simple interest
you can charge it monthly or yearly
find 4% and multiply by how many months or years
4% of 900=
0.04 times 900=36
that is each time the interst is added
if it is monthly, (6months so ) 6 times 36=216
if it is yearly (6months=1/2year so )6 times 1/2=3
if it is taken monthly, then Sam earns $216
if it is taken yearly, then Sam earns $3
The answer would be:
Fraction: 27/32
Decimal: 0.84375
The range is 31.
To find the range, you subtract the smallest number, in this case 14, from the largest number, in this case 45.
