Given the figure of a regular pyramid

The base of the pyramid is a hexagon with a side length = 6

The lateral area is 6 times the area of one of the side triangles

So, the side triangle has a base = 6

The height will be:

\begin{gathered} h^2=6^2+(\frac{\sqrt[]{3}}{2}\cdot6)^2=36+27=63 \\ h=\sqrt[]{63} \end{gathered}

so, the lateral area =

6\cdot\frac{1}{2}\cdot6\cdot\sqrt[]{63}=18\sqrt[]{63}

The mean of five numbers is 8. If one of the five numbers is removed, the mean becomes 9. What is the value of the number that w
mestny [16]

Using the mean concept, it is found that the value of the number that was removed was of 4.

<h3>What is the mean?</h3>

The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

The mean of five numbers is 8, hence, the sum of the numbers is given by:

S = 5 x 8 = 40.

If one of the five numbers is removed, the mean becomes 9, hence, the sum of the four numbers is given by:

S = 4 x 9 = 36.

The difference is:

40 - 36 = 4.

Hence, the value of the number that was removed was of 4.

GarryVolchara [31]
Answer=18 pages

Steven read 9 pages on Monday. If he needs to read DOUBLE that amount on Tuesday, then we need to take the number of pages he read on Monday and times it by 2.

9*2=18pages

Steven needs to read 18 pages on Tuesday.

**Remember that Double is the same as 'two times more', or 2x more...
