Answer:
Blockof silver's wieghing = 8 ounces
total rate = $104
therefore, one ounce=$104/8= $13
When you divide by a multiple of 10 or when you multiply by a multiple of 10.
Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.
I think the 40 30 20 should be going up not down like this 20 30 40
