Find the surface area of a pyramid with a square base with dimensions 100 mm by 100 mm and height of 75 mm.
Reil [10]

To solve for the surface area of the pyramid, we make use of the formula:

A= l w + l [sqrt ((w / 2)^2 + h^2)] + w [sqrt ((l / 2)^2 + h^2))

where,

l and w are the base of the pyramid = 100 mm

h is the height of the pyramid = 75 mm

 

Substituting the given values into the equation:

A= 100 * 100 + 100 [sqrt ((100 / 2)^2 + 75^2)] + 100 [sqrt ((100 / 2)^2 + 75^2))

A = 10,000 + 100 (sqrt 2575) + 100 (sqrt 2575)

A = 20,148.90 mm^2

 

Therefore the surface area of the pyramid is about 20,149 mm^2.

Emma uses turquoise beads to make bracelets to sell at an event. The total amount Emma earns, y, is proportional to the number
NNADVOKAT [17]
<h3>The equation represents the total amount Emma earns at the  event is y = 10x</h3>

<em><u>Solution:</u></em>

Given that,

<em><u>The total amount Emma earns, y, is proportional to the number  of bracelets, x, she sells</u></em>

y \propto x\\\\y = kx -------- eqn\ 1

Where,

y is the total amount Emma earns

x is the number of bracelets

k is the cost of each bracelet

<em><u>Emma earns $10 for each sold bracelet</u></em>

Therefore, k = 10

Thus, eqn 1 becomes,

<h3>y = 10x</h3>

Thus the equation represents the total amount Emma earns at the  event is found
