The surface areas of two similar pyramids are 48 m2 and 108 m2 Find the scale factor.
miskamm [114]

Answer:

\boxed{ \text{B. }\frac{2}{ 3}}

Step-by-step explanation:

The scale factor (C) is the ratio of corresponding sides of the two pyramids.

The ratio of the areas is the square of the scale factor.

\frac{A_{1}}{ A_{2}} =C^{2}\\ \\\frac{48 }{108} = C^{2}\\\\ \frac{4}{9} = C^{2}\\\\ C = \frac{2}{3}\\\\

The scale factor is \boxed {\frac{2}{3}}.

Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 3 feet, 4 f
aksik [14]

Using Pythagoras theorem,  we know that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The 5-foot side will fit to form a right triangle

<h3>How to use Pythagoras theorem to prove a right triangle?</h3>

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

Therefore,

c²= a²+ b²

where

  • c = hypotenuse side
  • a and b are the other legs.

Therefore,

3² + 4² = 5²

Hence,

Knowing that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The 5-foot side will fit to form a right triangle

Art [367]

t = 9

multiply both sides by 5 to eliminate the fraction

3t + 3 = 30 ( subtract 3 from both sides )

3t = 27 ( divide both sides by 3 )

t = 9
