Answer:
Number of days = 4879 days
Number of months = 162.63 months
Number of years = 13.37 years
Step-by-step explanation:
Given
Mia's age (in minutes) =
Required
Calculate age in years, months and days.
For ease of work, we'll start by converting to days.
First, it should be noted that there are 24 hours in one day
And there are 60 minutes in an hour.
This means that there are 24 * 60 minutes in a day
Number of minutes = 24 * 60 minutes
Number of minutes = 1,440 minutes
So, if number of minutes in a day is 1,440
Number of days in minutes is calculated as follows
Number of days =
Number of days = 4879 days
Now, we can convert this to month and year, easily.
From the question, it should be assumed that there are 30 days in a month.
If 1 month = 30 days
Then, there are months in 4879 days
Number of months =
Number of months = 162.63 months
Converting to year
From the question, it should be assumed that there are 365 days in a month.
If 1 year = 365 days
Then, there are years in 4879 days
Number of years=
Number of years = 13.37 years
The diary farmer should use 1000 pounds of 85 % protien and 55 % of 200 pounds to make 1200 pounds of a high-grade 80% protein ration
<em><u>Solution:</u></em>
Let the amount of 85 % protien supplement be "x"
Then amount of 55 % protien be (1200 - x)
According to given question,
85 % of "x" protien supplement + 55 % of 1200 - x protien used to get 80 % of 1200 pounds
85 % of x + 55 % of (1200 - x) = 80 % of 1200
Pounds of 85 % protien used = 1000 pounds
Then pounds of 55 % protien used = 1200 - 1000 = 200 pounds
Thus he should use 1000 pounds of 85 % protien and 200 pounds of 55 % protien to get 1200 pounds of a high-grade 80% protein ration
