Answer:
Room and board
30%
Step-by-step explanation:
If you look at the numbers in the table, you can easily see Room and board is the largest expense, with $127.50, three times more than the second place.
Now, to find the percent of that expense vs her income we just have to divide this big expense ($127.50) by the total income she has ($425).
% = $127.50 / $425 = 30%
So, that expense is 30% of her income, that's a big chunk, but it's normal for lodging expenses.
Answer:
a
Step-by-step explanation:
Our basis is the value 25 mg/kg·day. The mg at the numerator is for the dosage, the kg at the denominator is for the weight of the patient and the day is for the time of dosage. First convert the weight from pounds to kg knowing that there are 2.2 lbs in every 1 kg.
Weight = 50 lbs* 1 kg/2.2 lbs = 22.73 kg
The solution for prescribed dosage is:
25 mg/kg·day * 22.73 kg = 568.25 mg/day
Since there are 24 hours in day, then the dosage should be administered 3 times because 24/8 = 3. It is mentioned that there should be 3 equal doses. Therefore, the dosage should be:
Dosage = 568.25/3 = 189.42 mg every 8 hours
The value of y given the inverse relationship is 5.
<h3>What is the value of y?</h3>
If two variables vary inversely, as one variable increases, the other decreases in value.
The equation that is used to represent inverse relationship is:
y = k/x
Where k is the constant of proportionality
k = yx
k = 4 x 15 = 60
y = 60 / 12
y = 5
