Answer:

So 0.0000214 can be written as 2.14\times 10^{-9}cubic\ yard                

Step-by-step explanation:

We have given one cubic inch = 0.0000214 cubic yard

We have to convert this into scientific notation

We know that 0.0000214 can be written as \frac{214}{10000000}

We know that \frac{1}{10} can be written as 10^{-1}

So \frac{1}{10000000} can be written as 10^{-7}

So \frac{214}{10000000} can be written as 214\times 10^{-7}=2.14\times 10^{-9}cubic\ yard

Answer:

1.98 × 10^10

Step-by-step explanation:

First solve for how many text messages were sent out per one month:

22,000,000 × 900

19,800,000,000

Convert into scientific notation:

1.98 × 10^10

In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.

Ayo can someone help plzz,10 points ;)

19 wouldn’t be reasonable, but it’s a trick question, because it really depends on the weight of the items, but if we don’t know what items they are, then we have to predict that the biggest number would be to much, so I think it’s B, or 19.
Hope this helps.
