Answer: 60

Step-by-step explanation:

If the entire blue length is 100 and one of the parts of that is 64, the other part is 36.

So by the geometric mean theorem, letting the length of the dotted altitude be y,

$\frac{64}{y}=\frac{y}{36}\\y^{2}=64 * 36 =2304\\y=48$

So if y=48, by the Pythagorean $x=\sqrt{48^2 + 36^2}=60$ theorem,

Simplify each expression as much as possible, and rationalize denominators when applicable. . √36/√18= ?

tino4ka555 [31]

Answer:

√2

Step-by-step explanation:

Solving the given expression step by step:

$\frac{\sqrt{36} }{\sqrt{18} } = \frac{6}{3\sqrt{2} }\ \ \ [\because \sqrt{36} = 6 \ and \ \sqrt{18} = 3\sqrt{2}] \\ = \frac{3 \times 2}{3\sqrt{2} } = \frac{ 2}{\sqrt{2} }= \sqrt{2}$

We rationalize denominator and change it into a simpler form as soon as possible.

The dictionary is 3 inches thick. What is the volume of the dictionary

Yuki888 [10]

Answer:

Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches

Step-by-step explanation:

If the dictionary is a square ( all sides are equal ) the the volume is

V = Length * Length * Length = $L^{3}$

V = 3 * 3 * 3 = 27 $inch^{3}$

while if its rectangular ( all side are not equal ) shaped

V = Length * Width * Height (thickness)

V = L * W * 3 = 3LW $inch^{3}$
