Answer:

20,667.

Step-by-step explanation:

This is an arithmetic series:

3 + 9 + 15 + 21 + 27+ ...........+ 495

First term = 3 and common difference = 6.

Number of terms = ( 495 - 3 )/6 + 1

= 83.

So Sn = n/2(a1 + l) where a1 = first term and l = last term

S83 = 83/2(3 + 495)

= 41.5 * 498

= 20,667.

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

$x^2=4^2+4^2$

$x^2=16+16$

$x^2=32$

We take positive square root to obtain

$x=\sqrt{32}$

$x=4\sqrt{2}$

x=5.66ft

Rounding to the nearest feet we have x=6ft
