Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.
Step-by-step explanation: The figure below shows the area in question.
Area of a circle is given by
The walkway is a semicircle. Then, area will be:
The area that will be covered with glass is the area between the outer and the inner circles. So, area is
864

Answer:
20
Explanation:
To estimate, we round. 102.3 rounds to 100 and 4.7 rounds to 5; this means we divide 100/5, which is 20.
Since there are 9 hockey cards per page and it holds 900 hockey cards you can multiply 9 by 68 to get the total of 612 hockey cards. Then take 900 and subtract 612 from it and you should get 288 hockey cards in the album. Then divide that number by 9 to get the total number of pages filled 288/9=32 pages filled
V = a * b * c
V = 30
a = 5
b = 2
c = ?
30 = 5*2*c
30 = 10*c
c = 30/10 = 3
c = 3
(-2x^3 +x -5) * (x^3 -3x)
= x^6*(-2*1) +x^4*(-2*-3 +1*1) +x^3*(-5) +x^2*(-3) +x(-5*-3)
= -2x^6 +7x^4 -5x^3 -3x^2 +15x
