Why can we write zeros after a number when we multiply by 10, 100, or 1000.
allochka39001 [22]

Answer:

IT shows that we are increasing the value of the number. The more zeros at the end of a number that you multiply by, the bigger the number will be.

Examples: 76x100=7600

                  100x100=10,000

However many zeros are behind the number is what you add to the product.

A plumbing supplies manager realises he has a profit margin of 15%. His total sales for a month came $23,000. How much of this i
mart [117]
The percentage of profit margin that
the plumbing supplies manager realizes that he has = 15%
Total sales for the month made by the plumbing supplies manager = $23000
Then
Amount of profit that has been made
by the plumbing sales manager = 15% * 23000 dollars
                                                    = (15/100) * 23000 dollars
                                                     = 15 * 230 dollars
                                                     = 3450 dollars
So the plumbing manager makes a profit of $3450 in the month as can be seen from the above deduction.

our success rate ,depending on the year,is between 35 and 40 percent ,according to the website,in 2015,234 raptors were taken in
Vilka [71]
Number of raptors in 2015: 234

% success: between 35% and 40%

Formula

% =: [number of success rescues / number of total rescues] * 100 =>

number of success rescues = % * number of total rescuess / 100

Number of success rescues:

a) 35 * 234 / 100 = 0.35 * 234 = 81.9

b) 40 * 234 / 100 = 0.40 * 234 = 93.6

Then, the number of raptor rescues that were succesfull was about 82 to 94.
