Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3 of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.
Answer:
We can eliminate the second and third options because marking something up doesn't result in a number less than the original. Since we are told to select 3 options and there are 3 answer choices left we select the first, fourth, and fifth statements.
.15 repeating which is the 2nd one
Answer: 7.5 minutes
Step-by-step explanation: divide 30 by 4.
Answer:
184 feet
Step-by-step explanation:
To answer this question you need to convert the 48 inches first to feet, as fabric is sold by the foot. 48 in converts to 4 ft which is what we will use for each curtain. Since we need 46 curtains we will multiply 46 curtains by 4 feet which will give our answer of 184 feet.
