how do you use scientific notation to estimate the hours in a year

Answers

Answer:

8.760 x 10^3

Step-by-step explanation:

There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.

Answers

Answer:

there is no -1 it must be one so it is now 3/4 x 4/3=12/2=1

Step-by-step explanation:

When you divide by a fraction, you must take its reciprocal and multiply.
Andrew did not do that,

So, (-3/4) / (4/3) becomes (-3/4) x (3/4)

Round 545 to the nearest hundred

Answers

Answer:

500

Step-by-step explanation:

Answer:

500

When rounding to the nearest hundred, like we did with 545 we use these rules

first you would have to round the number up to the nearest hundred if the last two digits in the number are 50 or above.

then you would have to round the number down to the nearest hundred if the last two digits in the number are 49 or below.

lastly you would have to see if the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
