Ron placed a grilled cheese sandwich, a sneaker, a pinecone, and a dog collar together on a scale. the sandwich weighs 0.462 lb, the sneaker weighs 290.87 g, the pinecone weighs 0.0000453 ton, and the dog collar weighs 0.246 kg. there are 2.20462 pounds in one kilogram. how many ounces do all of these objects weigh in total?
a. 18.55 oz
b. 19.97 oz
c. 25.93 oz
d. 27.78 oz

Answer 1

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.

Answer 2

Answer: d. 27.78 oz

Step-by-step 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

$=0.462\times16=7.392\ oz$

Weight of sneaker=290.87g

$=0.29087\ kg=0.29087\times2.20462\ lbs\\=0.6412\ lbs=0.6412\times16\ oz=10.2601\oz$

Weight of pinecone=0.0000453 ton

$=0.0000453\times907.185\ kg\\=0.0410\ kg=0.0410\times2.20462\ lbs\\=0.09038942\ lbs=0.09038942\times16=1.4462\ oz$

Weight of dog collar=0.246 kg

$=0.246\times2.20462\ lbs\\=0.54233652\ lbs=0.54233652\times16\ oz\\=8.6773$

Total ounces of these objects weigh in total=

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