HELP ITS MAKING ME DO ANOTHER ONE

Anna007 [38]

Answer:

Since we know that each of the three triplets are the same age we can put next to n, 3.

And given that another child is 14 years old we can put that next to the "+" sign.

In total, it would equal 32, so put the 32 after the equal sign.

It should look like this:

3n + 14 = 32

But now they want us to solve for the triplet's ages, so we just solve for n;

3n + 14 = 32

-14 -14

3n = 18

/3 /3

n = 6, the triplet's ages are 6 years old each.

Let's solve :

${(2 {x}^{2} + 5) }^{ - \frac{5}{2} }$

$\dfrac{1}{{(2 {x}^{2} + 5) }^{ \frac{5}{2} } }$

$\dfrac{1}{ \sqrt{( 2{x}^{2} + 5) {}^{5} } }$

therefore, the correct choice is :

A trader purchased 1,000 books at the rate of $5.40 per book and spent $200 towards transportation. If he wants to earn a profit

Dmitriy789 [7]

Answer:

$6.3

Step-by-step explanation:

Cost of one book = $5.40

cost of 1000 books = 1000* Cost of one book = $5.40*1000 = $5400

Transportation cost for all the books = $200

Thus, total cost for all the books = cost of 1000 books + Transportation cost for all the books = $5400 + $200 = $5600.

Given , trader wants to earn a profit of 12.5%

thus, we find 12.5 % of total cost incurred by trader

12.5 % of total cost incurred by trader = 12.5/100 * $5600. = $700

Thus, total profit for 1000 books will be $700

we know that

selling price = cost price + profit

therefore, in the given problem

selling price for 1000 books = total cost for 1000 books + total profit

substituting the value as calculated above

selling price for 1000 books = $5600 + $700 = $6300

To find selling price for one book, lets divide LHS and RHS by 1000

selling price for 1000/100 books = $6300/1000 = $6.3

Thus, trader should sell each book at $6.3 to earn a profit of 12.5%.
