Answer:

A.23.75 is the total so there change is 1.25

B.9.60 for chicken, and 13.77 for beef the reasoning being you multiply the cost of pizza by every pound like 3x3.20

with subtraction coming in to determine how much more beef is 13.77-9.60=4.17 greater in cost

C.with one bottle she can fill 27.5 times as divison is only possible if the fractions are even which would be 1/10 55/10 divided by 2/10 equals 27.5 not entirely necessary to do for a whole number however it would take 2 10/11 bottles to fill a 16 litter jug seeing as 16=32/2 11/2 goes in twice and to avoid going over you'd need to keep the remaining 1/11 in the third bottle

Answer: $1.03*10^{-1}>3.1*10^{-2}>2.01*10^{-3}>2.32*10^{-4}>4.2*10^{-5}$

Step-by-step explanation:

1. A number written in scientific notation has the following form:

$a10^{b}$

Where is $a$ is a number between 1 and 10 but not including 10, and b is an integer.

2. The negative exponent indicates the number of places the decimal point must be moved to the left to obtain the number as a decimal number.

3. Keeping this on mind, you can know that: if the exponent of a number written in scientific notation indicates that the decimal point must be moved 5 places to the left and another number written in scientific notation indicates that the decimal point must be moved 2 places to the left, then the first number is smaller than the second one.

4. Therefore, you can arrange the numbers given in the problem as following:

$1.03*10^{-1}>3.1*10^{-2}>2.01*10^{-3}>2.32*10^{-4}>4.2*10^{-5}$
