The answer is <span>$494.55</span>
Let's first imagine a circle and calculate its area and then reduce it in half for the area of a semi-circle. Since this opening is above <span>a 30-inch wide door, the circle will have a diameter of 30 inches.
The area of the circle (A) is:
A = </span>π · r²
where:
π = 3.14
r - radius: r = diameter ÷ 2 = 30 ÷ 2 = 15 inches
So, the area of the circle is:
A = π · r² = 3.14 · 15² = 706.5 inches²
The area of the semicircle is half of the area of the circle:
A1 = A ÷ 2 = 706.5 ÷ 2 = 353.25 inches²
Since the stained glass window costs $1.40 <span>per square inch, for 353.25 square inches it will cost $494.55:
353.25 square inches * 1.40 $/square inch = $494.55</span>
The distance between the two points on the number line is of 
units.
-------------------------------------------
- The distance between two numbers on the number line is given by the <u>subtraction of the greater by the smaller number.</u>
- The greater number is
- The smaller is
. - The distance is:
Thus, distance of units.

Answer:
3/2
Step-by-step explanation:
It is proportional because it is 6/4 simplified.
Answer:
r=d/t
Step-by-step explanation:
d=rt
we are to make r the subject of the formula, so we remove t from the rhs.
we do this by dividing both sides by t
d divided by t= d/t and rt divided by t = r
therefore d/t =rt/t
= r=d/t
