They will ring again together at 10:15am. Because the common factor for 40, 48 and 60 is 240, which means 240 minutes, that equals to 4 hours. Hence 4 hours after 6.15am is 10.15am.
Hope this helps.
1 / (1/6) = x / (2/3)...1 drop to 1/6 dash = x drops to 2/3 dash
cross multiply
(1/6)(x) = (1)(2/3)
1/6x = 2/3
x = 2/3 * 6
x = 12/3 = 4 drops <==
The semicircle is 25pi or 78.54
The rectangle is 120 (12*10)
The triangle is 24 (.5*12*4)
So the total is 222.54 (78.54+120+24)
Answer:
201.06 square feet
Step-by-step explanation:
area of a circle is given by πr², where π = 3.1416
A = 3.1416 * 8²
A = 3.1416 * 64 = 201.0624 square feet
A = 201.06 square feet
So it's 8√2 cause you do c=a/h and manipulate the formula for 8/cos45 :)
