a. 18.55 oz
b. 19.97 oz
c. 25.93 oz
d. 27.78 oz

Answer 1

Answer: d. 27.78 oz

Explanation:

We know that 1 lb =16 oz

1 kg=2.20462 lbs

1 ton = 907.185 kg

Let's convert all of the given weights of objects in ounces by using above conversions.

Weight of sandwich=0.462 lbs

`=0.462*16=7.392\ oz`

Weight of sneaker=290.87g

`=0.29087\ kg=0.29087*2.20462\ lbs\\=0.6412\ lbs=0.6412*16\ oz=10.2601\oz`

Weight of pinecone=0.0000453 ton

`=0.0000453*907.185\ kg\\=0.0410\ kg=0.0410*2.20462\ lbs\\=0.09038942\ lbs=0.09038942*16=1.4462\ oz`

Weight of dog collar=0.246 kg

`=0.246*2.20462\ lbs\\=0.54233652\ lbs=0.54233652*16\ oz\\=8.6773`

Total ounces of these objects weigh in total=

`7.392+10.2601+1.4462+8.6773=27.7754\approx27.78\ oz`

Answer 2

First, you have to turn all of the weights from the unit that they are into ounces.

sandwich weighs 0.462 lbs is 7.392 ounces
sneaker weighs 290.87 g is 10.260 ounces
pinecone weighs 0.0000453 ton is 1.450 ounces
dog collar 0.246 kg is 8.677 ounces

Once you add these up you get 27.779 as a total which means the answer is D or 27.78 when you round to two decimal places.
