four dozen letters weigh 1kg 200g find the weight of
a 1 letter b 10 letters c 38 letters if each weighs the same amount.
please reply asap thank you:D
4 dozen = 4*12 = 48 letters
so
1.200 kg/48 letters
is our conversion factor, same top and bottom
a)
1 let (1.2 kg/48 let) = .025 kg or 25 grams
b)
then 10 let = .25 kg = 250 grams
c)
38 let(1.2kg/48 let) = .95 kg = 950 grams
thank you damon
You are welcome.
To find the weight of each letter, we need to determine the weight of one letter from the given information.
First, let's convert the weight of four dozen letters to grams. Since one dozen is equal to 12, we know four dozen is equal to 4 * 12 = 48 letters.
We are given that 48 letters weigh 1 kg 200g, which is equivalent to 1200g + 200g = 1400g.
To find the weight of one letter, we divide the total weight by the number of letters:
Weight of one letter = Total weight / Number of letters
Weight of one letter = 1400g / 48 letters
Using simple division, we find that the weight of one letter is 29.17g (rounded to two decimal places).
Now that we know the weight of one letter, we can calculate the weight of:
a) 1 letter: 29.17g
b) 10 letters: 29.17g * 10 = 291.7g (rounded to one decimal place)
c) 38 letters: 29.17g * 38 = 1109.46g (rounded to two decimal places)
Therefore, the weight of:
a) 1 letter is 29.17g
b) 10 letters is approximately 291.7g
c) 38 letters is approximately 1109.46g.
