Answer:
Kindly rewrite the question clearly.
Answer:
15 ounces
Step-by-step explanation:
If there is 165 ounces in 11 boxes then divide the ounces by the boxes to get the amount of ounces in one box.
Given that we have 47 kids and each kid needs 10 marbles, find out how many bags of 24 marbles will we need.
First, we will multiply 47 by 10 to get the amount of marbles needed.
47 x 10 = 470
So, that means we need 470 marbles in total.
Then, we divide 470 by 24 to see how many bags of 24 marbles 470 marbles is.
470 / 24 = 19.5833
Since, we can't have 19.5833 bags, we have to check what it would be if we only used 19.
19 x 24 = 456
470 - 456 = 14
Since, 18 is the closest number of bags but it has less than 470 it would not be correct.
Therefore, the best answer would be B. 25 since it is better to have extra marbles but not a very wide margin.
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
Amount of quarts of acid and water = 5
Percentage of acid = 40%
So, Amount of acid is given by

Amount of water is given by

So, we need to find the amount of water must be added to the mixture to get weakened to 30% acid.
Let x amount of water is added to mixture, so that water gets 70% of mixture and acid becomes 30% of mixture.
According to question,

Hence, Second option is correct.
Answer: " \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " .
_______________
Step-by-step explanation:
_______________
This is a "unit rate" problem;
that is: we want to solve for a particular quantity per [single] unit.
_______________
→ in this case, per single "hour" ;
_______________
So we convert:
_______________
" 2 gal per 8 hours" ; to the correct number of:
_?_ gal per [single] hr.
_______________
{<u>Note</u>: "gal" refers to: "gallon(s)" ;
"hr" refers to: "hour(s)" .}.
_______________
→ "
gal / hr. " ;
_______________
→ " {
[2÷2] / [8÷2] = 1/4 ;
_______________
So, the answer is:
→ "
" ;
_______________
or: write as decimal:
→ "
= (1 ÷ 4) = 0.25 " ;
_______________
write the answer as:
_______________
→ " 0.25 gal/hr. "
_______________
Or, when we had:
→ "2/8" gal/hr ;
_______________
Use calculator:
→ "
= "2 ÷ 8" ;
= " 0.25 gal/ hr.
_______________
So: The correct answer is:
_______________
" \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " ;
_______________
