A square pyramid has base edge length 14 m. The height of the pyramid is 24 m. Find the surface area of the square pyramid. Use

kotegsom [21]

Answer:

The total surface area is 896 $m^{2}$

Step-by-step explanation:

The square pyramid is a solid with square base and symmetric 4 triangular faces.

Given that the square base is 14 m and height is 24 m.

The apex of pyramid, center of square and center of any edge of square make a right angled triangle.

Let that height if triangular face be "x".

by pythagoras theorm , $x^{2} = 7^{2} + 24^{2} = 625$

x = 25 m

the area of square base is $14^{2} = 196 m^{2}$

the area of each triangular side is  $(\frac{1}{2})(base)(height) = (\frac{1}{2})(14)(25) = 135 m^{2}$ 

such are 4 triangles, thus $(4)(135) = 700 m^{2}$

Thus the total surface area is 196 + 700 = 896 $m^{2}$

The manager of a theater noted that for every 10 admission tickets sold, the theater sells 3 bags of popcorn at $2.25 each, 4 so

Shalnov [3]

Answer:

$1.475 is the average amount of snack sales per ticket sold.

Step-by-step explanation:

We are given the following in the question:

Number of popcorn bags sold = 3

Cost of a popcorn bag = $2.25

Total cost of popcorn bag = $2.25\times 3$ = $6.75

Number of soda sold = 4

Cost of a soda = $1.50

Total cost of soda = $1.50\times 4$ = $6.00

Number of candy bars sold = 2

Cost of a candy bar = $1.00

Total cost of candy bars = $1.00\times 2$ = $2.00

Total sales =

Total cost of popcorn + Total cost of soda + Total cost of candy bar

$= 6.75 + 6 + 2\\=\$14.75$

$\text{Average} = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

Average amount of snack sales per ticket sold =

$\dfrac{\text{Total sales}}{\text{Number of tickets}} = \dfrac{14.75}{10} = 1.475$

Thus, $1.475 is the average amount of snack sales per ticket sold.
