Eddie is correct about his prediction. A coin has two sides, one head, one tail, so there is a 50% chance that it will land heads every time Eddie flips the coin. I would tell Eddie that his prediction is reasonable and mathematically correct.
780, or C, is correct. Since 9.75 is 1/80th of the actual measurement, we can set up an equation like this:
9.75 = 1/80x
Then multiply each side by 80:
780 = x
The actual building's height is 780 ft.
We can check this answer by plugging in 780 for x in the original equation:
9.75 = 1/80(780)
9.75 = 9.75

what about using 20-30-40-5
Step-by-step explanation:
the sequence is that you are skipping ten to get the second nb which is 30 and keep on going on to get 50
Answer:
1436.8 cm^3
Step-by-step explanation:
You just plug it in:
r = 7 since it is the radius
Volume = (4 / 3) pi x r^3
Volume = (4 / 3) pi x (7)^3
Volume = 1436.75 = 1436.8 cm^3 (nearest tenth)
