Answer:

Step-by-step explanation:

The first two have a common difference of 4

2 6 10

To get from 2 to 6 you need to add 4 to the 2.

-7 -3 1

Add 4 to -3 and you get 1. This works.

The last one seems to be playing hop scotch all over the place (hop scotch is not a technical term. It is just by way of saying it's not arithmetic).

Find the volume of this square<br> based pyramid.<br> 5ft<br> 6 ft<br> [? ]ft
Sav [38]

Answer:

48 ft³

Step-by-step explanation:

To find the height, you can use the slant height and the base.

Using the Pythagorean Theorem and 3 as the triangle's base,

a²+b²=c²

3²+b²=5²

9+b²=25

b²=16

b=4

The height of the pyramid is 4.

Volume formula for the pyramid is \frac{1}{3} *b*h

Inserting our measurements:

\frac{1}{3} *6*6*4=\\2*6*4=\\12*4=\\48
