explain how multiplying a whole number and a decimal is similar to and different from multiplying whole numbers
Answers
Similar :
Ignore the decimal point and multiply the numbers
Difference :
Count the decimal places and put the decimal point in the final answer
Given :
multiplying a whole number and a decimal
similar :
When we multiply a whole number by a decimal then we ignore the decimal first and the we multiply as if we multiply the whole numbers .
So, its similar like multiplying whole numbers
Different:
After multiplying the numbers as if we multiply like whole numbers , we move the number of decimal places from the left that we have in the decimal number and write the final answer with decimal point .

Explanation:
The process is very similar. We multiply the digits the same was as we would multiply whole numbers. We start at the last place value and multiply, working our way left with each line. At the end of the process, we add the lines together.
The difference comes with the decimal point. After we are finished multiplying, we count the number of digits behind a decimal (total) in the problem. This is how many digits will be behind a decimal in the answer.

Answers
6b-49=2(b-3) becomes 6b-49=2b-6
From there you can group the b's together by subtracting 2b from both sides, leaving you with 4b-49=-6
Now you can get the b's alone by adding 49 (to cancel out -49) to both sides, giving you 4b=43, You're still trying to get b by itself, so what you'll do is divide both sides by 4, giving you b=10.75

different types of coins there are. All we know is that all 10 of them
on the scale at the same time have 45 grams of mass.
IF all the coins happen to be identical ... AND each one is worn down
the same amount, AND each one has the same amount of dirt and oil
on it ... then each one has (45/10) = 4.5 grams of mass.
But those are some big IFs.
There are 4.5 grams in each coin.

The formula for surface area of a cylinder:
S.A. = 2πrh + 2πr², where r is the radius and h is the height.
The radius and height are given as follows:
r = 8
h = 16
Plug them into the above formula and solve.
S.A. = 2πrh + 2πr²
S.A. = 2π(8)(16) + 2π(8)²
S.A. = 256π + 2π64
S.A. = 256π + 128n
S.A. = 384π or approx. 1206

Answer:
384π units² or approximately 1,206 units².
