Opposite rays connected at their endpoint form a line. A line is continuous infinitely in both directions.
248/4 = 62
to check if you are right
you do
62*4= 248
or you can do
248/62= 4
You can check in both way
Step-by-step explanation:
For x = 7 or y = f(7)
Graph and solution are in the picture below
Answer:
Step four
Step-by-step explanation:
When solving equations you have to flip the sign when you divide negative integers.
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>
