A is correct.
It would take 6 "jumps" the left of 4.14 x 10^-6 to move the decimal back to where it actually is when not in scientific notation.   0.00000414

Can you show how to solve this question? Thomas and Sharlina work on weekends and holidays doing odd jobs around the neighborhood. They are paid by the day, not by the hour. They each earn the same whole number of dollars per day. Last month Thomas earned $184 and Sharlina earned $207 a. How many days did each person work? b. Whatis their daily pay PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER

To find out how much they earned, we need to find the GCF of 184 and 207.

The greatest common factor (GCF) of 184 and 207 is 23.

That means they earn 23 dollars per day. That is your answer for part b.

And Thomas worked 184/23 = 8 days
While Sharlina worked 207/23 = 9 days

That is your answer for part a.

Mei is writing 4.28 as a mixed number. Find her mistake and correct it.

4.28 is a decimal and not a mixed number. To write it as a mixed number you keep the 4 and put 28 over 100 then simplify.

4.28= 4 28/100 (simplify)
4 28/100= 4 14/50= 4 7/25

4.28 as a mixed number would be 4 7/25

QUESTION POSTED AT 09/12/2019 - 03:58 AM

Suppose you bought a pizza for $8.00. You also bought a salad but you can not remember how much you paid and you can not find the receipt.You know the total amount you spent was $10.00. Which equation would best to answer to find the cost to the salad A:8.00+$=10.00 B:8.00+10.00=$ C:8.00 x $=10.00 D.10.00 x $ = 8.00

The best equation would be A.

with A you get to calculate what is the value of $. 

8 + $ = 10 (10 is the total value of your receipt and 8 is the price of pizza)
$ = 10 - 8 (we transfer the price of pizza on the other side to the total amount of your receipt and calculate the remaining amount)
$ = 2

We see that the remaining amount is 2$, which means the salad cost s2$ :)
