An average american will throw away 90,000lb of trash over his or her lifetime. convert this weight to kilograms using the fact that 1kg=2.2lb. round to the nearest hundred.

The weight of the trash is 40,900 kilograms

Step-by-step explanation:

∵ 1 kilogram = 2.2 Ib

That means if you want to convert quantity from Ib to kilogram divide the quantity by 2.2 or you can use the ratio method to do that

→  kg    :    Ib

→  1       :    2.2

→  x       :    90,000

Now by using cross multiplication

∵ x × 2.2 = 1 × 90,000

∴ 2.2 x = 90,000

- Divide both sides by 2.2

∴ x = 90,000 ÷ 2.2

∴ x = 40909.09091

- Round it to the nearest hundred

∵ The number before the hundred place is 0

∴ The number in the hundred digit will not change

- Change the unit digit and ten digit to 0

∴ x ≅ 40900 to the nearest hundred

∵ x represents the quantity of the trash in kilogram

∴ The weight of the trash is 40900 kilograms

3rd box is the answer

step-by-step explanation:

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
