Answer:
- area of rectangle: 48 cm²
- area of triangle: 18 cm²
- shaded area: 30 cm²
Step-by-step explanation:
The area of a rectangle is given by the product of its length and width.
... A = LW
For your rectangle, the overall area is ...
... A = (12 cm)(4 cm) = 48 cm² . . . . rectangle area
___
The area of a triangle is half the product of its base and height. Your triangle is shown with a base of 9 cm, and its height is the height of the rectangle, 4 cm. The triangle area is ...
... A = (1/2)bh
... A = (1/2)(9 cm)(4 cm) = 18 cm² . . . . triangle area
___
The shaded area of the figure is the difference between the rectangle area and the triangle area. (The triangle is fully included in the rectangle, but is not shaded.) That difference is ...
... shaded area = rectangle area - triangle area
... shaded area = 48 cm² - 18 cm² = 30 cm² . . . . shaded area
Given:
8:03 = 188 empty seats
8:10 = 160 empty seat
188 - 160 = 28 empty seats
8:10 - 8:03 = 0:07 minutes
28 / 7 minutes = 4 empty seats per minute
8:00 - 8:03 = 3 minutes
3 minutes * 4 seats per minute = 12 seats
188 + 12 = 200 empty seats at 8:00
8:15 - 8:10 = 0:05 minutes
5 minutes * 4 seats per minute = 20 empty seats
160 - 20 = 140 empty seats at 8:15
200 - 120 = 80 empty seats
80 empty seats / 4 empty seats per minute = 20 minutes
120 empty seats at 8:20.
8:00 = 200 empty seats
200 / 4 = 50 minutes
8:00 + 0:50 = 8:50 is the time when there are no empty seats left.
S=d/t
s=40/4
s=10
Therefore the average speed of the football is 10yd/s!
24,000 / 3 = 8000 x 2 = 16,000
16,000 / 650 = 24.6 (25) Days
