What we need to do is find out what 29% of 639 is and add it to 639 to find the total.  The easiest way to find a percentage of a number, if you don't know how to calculate it, is by taking 10%.  So 10% of 639 is 63.9.  Now since there is 29%, we need to multiply 63.9 x 2, to get 127.8.  However, we only have 20% out of the 29%.  So we need to find the other 9%.  If 10% is 63.9, then 1% is 6.39.  So we need to multiply 6.39 x 9, and that equals 57.51.  Now, we need to add 127.80 and 57.51 together.  That will give us 185.31.  Add that to the 639, and you have your answer.  Hope this helped!

16/8 would be classified as a/an?<br> A:whole number <br> B:integer <br> C:Rational Number
gregori [183]

Answer:

Whole Number

Step-by-step explanation:

Numerator. This is the number above the fraction line. For 16/8, the numerator is 16.

Denominator. This is the number below the fraction line. For 16/8, the denominator is 8.

Improper fraction. This is a fraction where the numerator is greater than the denominator.

Mixed number. This is a way of expressing an improper fraction by simplifying it to whole units and a smaller overall fraction. It's an integer (whole number) and a proper fraction.

Now let's go through the steps needed to convert 16/8 to a mixed number.

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

16/8 = 2

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (2) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:

16 - (8 x 2) = 0

Step 3: Our mixed fraction

We've now simplified 16/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

2 (0/8)

You maybe have noticed here that our new numerator is actually 0. Since there is no remainder, we can remove the entire fraction part of this mixed number, leaving us with a final answer.

When Sarah turned 18, she took $500 from her savings and opened a
Montano1993 [528]

The worth of Sarah's investment when she is 68 is $14,728.51.

<h3>What is the worth of the investment?</h3>

The formula that can be used to determine the worth of the investment is:

FV = P (1 + r)^n

FV = Future value

P = Present value

R = interest rate

N = number of years = 68 - 18 = 50

$500 x (1.07)^50 = $14,728.51

Julio makes a scale drawing of the kitchen floor to determine how
tatuchka [14]

The scale drawing of Julio's kitchen would change the kitchen size

The actual area is 243 square feet

<h3>How to determine the actual area of Julio's kitchen?</h3>

The parameters are given as:

  • Length = 4.5 inches
  • Width = 3.375 inches

Start by converting the dimensions to feet using the scale ratio

  • Actual length = 4.5 inches/ (1 inch/ 4 feet) = 18 feet
  • Actual width = 3.375 inches/ (1 inch/ 4 feet) = 13.5 feet

The area is then calculated as:

Actual Area = Actual length * Actual Width

This gives

Actual Area =18 feet * 13.5 feet

Evaluate the product

Actual Area = 243 square feet

Hence, the actual area is 243 square feet
