(AAAA HELP PLS XD WILL MARK BRAINLIEST) Nhia is setting up a marble tournament for the kids in her

aksik [14]

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.

A mixture contains five quarts of acid and water and is forty percent acid. If the mixture is to be weakened to thirty percent a

kari74 [83]

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

$\frac{40}{100}\times 5\\\\=2\ quarts$

Amount of water is given by

$5-2=3\ quarts$

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,

$\frac{3+x}{2}=\frac{70}{30}\\\\\frac{3+x}{2}=\frac{7}{3}\\\\3(3+x)=2\times 7\\\\9+3x=14\\\\3x=14-9\\\\3x=5\\\\x=\frac{5}{3}\\\\x=1\frac{2}{3}\ quarts$

Hence, Second option is correct.

Isabella painted her bedroom. She used 2 gallons of paint and finished in 8 hours. At what rate did Isabella paint the room?

GrogVix [38]

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.

_______________

{Note: "gal" refers to: "gallon(s)" ;

"hr" refers to: "hour(s)" .}.

_______________

→ " $\frac{2 gal}{ 8 hr} = [\frac{2}{8}]$ gal / hr. " ;

_______________

→ " { $\frac{2}{8} =$ [2÷2] / [8÷2] = 1/4 ;

_______________

So, the answer is:

→ " $\frac{1}{4} gal /hr$ " ;

_______________

or: write as decimal:

→ " $\frac{1}{4}$ = (1 ÷ 4) = 0.25 " ;

_______________

write the answer as:

_______________

→ " 0.25 gal/hr. "

_______________

Or, when we had:

→ "2/8" gal/hr ;

_______________

Use calculator:

→ " $\frac{2}{8}$ = "2 ÷ 8" ;

= " 0.25 gal/ hr.

_______________

So: The correct answer is:

_______________

" \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " ;

_______________
