Answer:

A. Close to (4,2)

Step-by-step explanation:

When solving a system of equations by setting them equal to one another, the resulting co-ordinates models the coordinates at which the lines intersect. In this case, from the graph, it looks like the lines cross at about 4 on the x-scale, and about 2 on the y-scale.

If a right triangle has a hypotenuse equal to 17 and a leg equal to 15, find the third side.

Yanka [14]

Use the pythagorean theorem a.k.a ${a}^{2} + {b}^{2} = {c}^{2}$
c is the hypotenuse while a & b are the legs
${15}^{2} + {b}^{2} = {17}^{2}$
$225 + {b}^{2} = 289$
subtract 225 from 289
${b}^{2} = 64$
square root both b and 64
the other leg is equal to 8

Vladimir [108]

If the sales department wants to place an order for 253,625 third grade math books for a region. How can the sale manager estimate the number of math books to be sure that there are more then enough is: The manager should carryout survey based on the number of people per class and provide 25,362 books.

<h3></h3><h3>How the sale can manager estimate the number of math books </h3>

Since extra math's books will be needed after giving out the available math's books.

Hence:

Additional maths books=10%× 253,625

Additional maths books=25,362 books

Based on the above calculation the manager should carryout survey based on the number of people per class and provide them with 25,362 books.

Therefore how can the sale manager estimate the number of math books to be sure that there are more then enough is that the manager should carryout survey based on the number of people per class and provide 25,362 books.
