Answer:

that would be 5 inches

Step-by-step explanation:

if you measure five ft that would be really big, 5 yards is way too big for a cd to be and five miles is 5,280 feet so 5 inches would be the only logic answer

hope this helps!

We know that :

⊕ Sum of the interior angles in a Pentagon should be equal to 540°

⇒ x° + (2x)° + (2x)° + 90° + 90° = 540°

⇒ (5x)° = 540° - 180°

⇒ (5x)° = 360°

$\sf{\implies x^{\circ} = \dfrac{360^{\circ}}{5}}$

⇒ x° = 72°

Multiply fractions is really hard for me because I hate fractions

earnstyle [38]

It’s not that hard all u need to do is when u multiply it just multiply it. For example what’s 2/3x4/3=8/3 and that is just 8/3 but when the denominator is different u just multiply it it’s not that hard

The surface area of a pyramid is 327 square meters. what is the surface area of a similar pyramid that is smaller by a scale fac

N76 [4]

Answer:

$\boxed{\text{144.33 m}^{2}}$

Step-by-step explanation:

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

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

$\dfrac{A_{1}}{ A_{2}} = C^{2}\\\\\dfrac{\text{327 m}^{2}}{A_{2}} = \left (\dfrac{1}{\frac{2}{3}}\right)^{2}\\\\ \dfrac{\text{327 m}^{2}}{A_{2}}= \dfrac{9}{4}\\\\\text{1308 m}^{2}= 9A_{2}\\\\A_{2} = \text{145.33 m}^{2}\\\text{The surface area of the smaller pyramid is \boxed{\text{145.33 m}^{2}}}$
