The diagonal of a square is 60 in, as shown

andre [41]

Answer:

The length of side is 42.4 inches.

Step-by-step explanation:

Given that:

Diagonal of square = 60 inches

As all sides of a square are equal, thus

Side of square = x

The diagonal will be the hypotenuse of a right angled triangle.

Using Pythagorean theorem;

$x^2+x^2=(60)^2\\2x^2=3600\\x^2=\frac{3600}{2}\\x^2=1800$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{1800}\\x=42.4$

Hence,

The length of side is 42.4 inches.

ira [324]

Answer:

(-1,0)

Step-by-step explanation:

Point B is located one position to the left on the x-axis resulting in a negative x-value in the coordinate pair, and Point B is located 0 units up on the graph resulting in a y-value of 0. Therefore, (-1,0) are the coordinates.

If a pair of jeans cost 45 dollars before the sale and the sale is taking 9 dollars off of the original price what was the perce

Dvinal [7]

Answer:

20%

Step-by-step explanation:

A pair of jeans cost $45 before the sale.

The sale is taking $9 off of the original price.

Then

$45 - 100%

$9 - x%

Write a proportion:

$\dfrac{45}{9}=\dfrac{100}{x}$

Cross multiply:

$45\cdot x=9\cdot 100\\ \\45x=900\\ \\x=\dfrac{900}{45}\\ \\x=20\%$
