HELP! What’s the average of 279 minutes?

<h3>Answer: 56 minutes</h3>

1 hour = 60 minutes

The time values given, in minutes, are:

25, 55, 60, 94, and 46

going from monday to friday in that exact order

Add up the values, then divide by 5. This is because there are 5 values

So adding up the values gets us: 25+55+60+94+46 = 280

Then dividing by 5 leads to this answer: 280/5 = 56

note: you must convert the "1 hour" to "60 minutes" because each time value must be in the same units. Otherwise, its like mixing apples and oranges which makes no sense.

Write the explicit formula for the geometric sequence 2, 8, 32, 128
Alja [10]
The first term, a, is 2.  The common ratio, r, is 4.  Thus,

a_(n+1) = 2(4)^(n).

Check:  What's the first term?  Let n=1.  Then we get 2(4)^1, or 8.  Is that correct?  No.

Try this instead:

a_(n) = a_0*4^(n-1).  Is this correct?    Seeking the first term (n=1), does this formula produce 2?      2*4^0 = 2*1 = 2.  YES.

The desired explicit formula is   a_(n) = a_0*4^(n-1), where n begins at 1.

Dorothy's dietary intake for one day consisted of 250 grams of carbohydrate, 60 grams of protein, and 40 grams of fat. What perc
tester [92]

Answer:

\%Percent = 17.14\%

Step-by-step explanation:

Given

Carbohydrate = 250\ g

Protein = 60\ g

Fat = 40\ g

Required

Determine the percentage of protein

First, we need to calculate the total:

Total = Carbohydrate + Protein + Fats

Total = 250\ g + 60\ g + 40\ g

Total = 350\ g

Percentage of protein is calculated as thus:

\%Percent = \frac{Protein * 100\%}{Total}

\%Percent = \frac{60 * 100\%}{350}

\%Percent = \frac{6000\%}{350}

\%Percent = 17.14\%
