Work is on piece of paper, yet I don't have a phone. I'm certain that is the answer.
A pyramid always have a number of slant triangles equal to the number of the sides of the base.
This means that a pyramid always have the number of face which is one more than the number of sides of the base.
Therefore, given that a pyramid has n number of sides of the base, the expression for the number of faces of the pyramid is given by
number of faces = n + 1.

Answer:</h2>
<em>The course costs, approximately, </em><u><em>$0.16 per hour</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h3>1. Convert the 10 weeks to hours.</h3>
10 weeks * 7= 70 days
70 days * 24= 1680 hours
<h3>2. Calculate cost/hour.</h3>
<em>Establish a rule of 3.</em>
<em>1680 hours -----> $275</em>
<em>1 hour -----> x</em>
<em>x= (1 hour * $275) / 1680 hours</em>
<em>x= 0.1636904762 ---> Round to the nearest cent.</em>
<em>x= 0.16 ---> Final result.</em>

Answer:
I. L = 17 cm.
II. W = 11 cm.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 56cm
Translating the word problem into an algebraic expression, we have;
L = W + 6 .....equation 1
The perimeter of a rectangle is given by the formula;
P = 2(L + W)
56 = 2(L + W) ......equation 2
Substituting eqn 1 into eqn 2, we have;
56 = 2(W + 6 + W)
56 = 2(6 + 2W)
Opening the bracket, we have;
56 = 12 + 4W
4W = 56 - 12
4W = 44
W = 44/4
W = 11 cm
Next, we would find the length of the rectangle;
From eqn 1;
L = W + 6
L = 11 + 6
L = 17 cm
