Determine if 0.84375 is rational or irrational and give a reason for your answer.Reasons Below

Answers

Answer: Rational because it is a decimal that terminates.

Step-by-step explanation:

A rational number can be expressed as a ratio/ fraction of two integers so there are several methods of knowing if a number is rational or irrational.

One such way is if it is a decimal that terminates. A terminating decimal is one that has a set amount of numbers after the decimal and hence does not continue forever. This number is rational because it can be expressed as a fraction.

0.84375 in fraction form would be, 84,375/100,000.

Given the set of numbers: {3, 8, 2, 2, 5} Find the mean. Enter your answer as a whole number with zero decimal places.

Answers

Answer:

Step-by-step explanation:

The mean is defined as adding all the numbers up and dividing by how many numbers there are, so:

3+8+2+2+5 = 20, 20/5 = 4

Answer:

Step-by-step explanation:

mean is the average so you add up all the numbers and divide by the number of addicts.

3 + 8 + 2 + 2 + 5 = 20

Subtract and write the difference in simplest form 12 5/8 - 7 1/3

Answers

Answer:

5 7/24

Step-by-step explanation:

Given the following mathematical expression;

12 5/8 - 7 1/3

First of all, we would subtract the whole numbers;

12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3

12 5/8 - 7 1/3 = 5 [5/8 - 1/3]

Next, we subtract the fractions from each other;

5/8 - 1/3

Lowest common multiple (lcm) = 24

5/8 - 1/3 = (15 - 8)/24

5/8 - 1/3 = 7/24

Combining the two parts, we have;

12 5/8 - 7 1/3 = 5 7/24

Find the percent change from a stock that was worth $230 and is now $287

Answers

Answer:

24.78%

Step-by-step explanation:

Initial price = $230

Final price = $287

change in price = final price - initial price

= 287 - 230

= $57

Percent change

= (change in price / initial price) x 100%

= (57 / 230) x 100%

= 24.78%

Find the area of this circle. Use 3 for pi

Answers

Answer:

area = 108 cm^2

Step-by-step explanation:

area = Pi(r^2)

using Pi = 3

r = D/2 = 12/2 = 6

area = 3(6^2) = 3(36) = 108 cm^2
