Answer:

Step-by-step explanation:

By the geometric mean theorem,

$GE=\sqrt{12 \cdot 6}=6\sqrt{2}$

So by the Pythagorean theorem,

$x=\sqrt{12^{2}-(6\sqrt{2})^{2}}=6\sqrt{2}$

$y=\sqrt{6^{2}+(6\sqrt{2})^{2}}=6\sqrt{3}$

for an art project you make a square print with a side length of 8 inches. You make a frame using strip of wood 1 1/4 inch wide.

lord [1]

Given that square print has side length = 8 inches

Given that you make a frame using strip of wood 1 1/4 inch wide. Since frame is on both sides of the square print so new side length after adding the frame = $1 \frac{1}{4} + 8 + 1 \frac{1}{4} = 10 + \frac{2}{4} = 10 + \frac{1}{2} = 10.5$ inches

Area of the square is given by formula $= x^2$ where x is the side of square

Shape of the frame including print will also be square so

Area of the frame including print $= 10.5^2 = 110.25$ square inches

Area of the print = $8^2 = 64$ square inches

We have to find the area of frame only so we can subtract area of print from the total area

Area of frame = [Area of frame including print] - [Area of print]

Area of frame = 110.25-64 = 46.25

Hence final answer is 46.25 square inches

Graph the solution of the system of linear inequalities.<br> y≤−4x−4<br> y≥x+2

tamaranim1 [39]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y\leq -4x-4$ ----> inequality A

The solution of the inequality A is the shaded area below the solid line $y=-4x-4$

The y-intercept of the solid line is -4

The x-intercept of the solid line is -1

The slope of the solid line is negative

$y\geq x+2$ ----> inequality B

The solution of the inequality B is the shaded area above the solid line $y=x+2$

The y-intercept of the solid line is 2

The x-intercept of the solid line is -2

The slope of the solid line is positive

The solution of the system of inequalities is the shaded area between the two solids line

see the attached figure

The math club is selling gift wrap for a funraiser. They sold 45 rolls of soild wrapping paper at $4 each and rolls of patterned

Lunna [17]

4 * 45 = 180

265 - 180 = 85

85/5 = 17

They sold 17 rolls of patterned wrapping paper.

What is Rational Number

abruzzese [7]

Rational number, in arithmetic, a number that can be represented as the quotient p/q of two integers such that q ≠ 0. In addition to all the fractions, the set of rational numbers includes all the integers, each of which can be written as a quotient with the integer as the numerator and 1 as the denominator.
