Scott needs to replace a broken window at his house. The window is shaped like a triangle with
dimensions shown below. If glass costs $18.75 per square foot, how much with the replacement
window cost?

Step-by-step explanation:

Find the volume of the triangle and then multiply it by the unit cost for the glass:

Supposing the glass is in the shape of an equilateral triangle of side length s.  The height of the triangle is s*sin 60 degrees.  Thus, the area of the triangle is  A = (1/2)(base)(height) = (1/2)(s)(s*sin 60 degrees or approximately

A = (1/2)(s^2)(1/3)√3 square feet.  This simplifies to

A = (1/6)√3s^2 ft^2.

Then the glass cost is (1/6)(√3)s^2($18.75 per ft^2).

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
