Emma always learned that when you multiply by a power of ten, all you need to do is add a zero. She used that trick to solve the following problems: 345 x 10 = 3,450
4,789 x 100 = 478,900
5.6 x 10 = 5.60

Emma’s sister told her that her “trick” doesn’t work, and that 5.6 x 10 is NOT 5.60.
Which girl is correct? How do you know?

help meee plsss you smart people

Her sis is right

Step-by-step explanation:

She is correct because if you multiply a decimal by a power of 10 instead of adding a zero you bring numbers out of the decimal state.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
