The human body is made up of about 37.2 trillion blood cells. That’s a lot of blood cells! Instead of writing 37,200,000,000,000 to express this very large number, we use scientific notation to write it as 3.72 × 1013.

A. Research to find another large or small number from a real-world situation. Write the number in scientific notation. Provide a hint that describes what your number represents.
B. Read another student’s post and guess what that student's number describes. Then write the number in standard form. Try to choose a post that doesn’t have any responses to it yet.
C. Respond to all replies to your post. For each post, check whether the number is correctly written in standard form and whether the student correctly guessed what your number represents. At the close of the discussion, reveal the answer.

What could be x and y?

Answers

X= 60 or (60, 0) and Y = 30 or (0,30)

Answer:

20 for both x and y

Step-by-step explanation:

if we substitute 20 for x, we get 2x20 which is 40.

If we substitute 20 for y, we get 4x20 which is 80.

80 plus 40 is 120.

Hence the answer is 20 for both x and y

What is the quotient of 5/12 and 1 and 1/6?

Answers

Answer:

5/14

Step-by-step explanation:

The quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).

What is a quotient?

A quotient in mathematics is the amount created by dividing two numbers. The term "quotient" is used frequently in mathematics and is sometimes known as the integer portion of a division, a fraction, or a ratio.

Given fractional numbers are 5 / 12 and 1(1/6). The quotient will be calculated as below:-

Quotient = ( 5 / 12 ) ÷ ( 1 ( 1 / 6)

Quotient = ( 5 / 12 ) ÷ ( 7 / 6 )

Quotient = ( 5 / 12 ) x ( 6 / 7 )

Quotient = 5 / 14

Therefore, the quotient of the given numbers 5 / 12 and 1(1/6) will be ( 5 / 14 ).
