Answer:
19.375 m.
Step-by-step explanation:
Before the first bounce it has travelled 10 meters.
Then after just hitting the ground the second time it has travelled 10 +1/2(10) = 15 m.
The common ratio is 0.5 and we want the sum of 5 terms
= a1 (1 - r^n) / (1 - r)
= 10 * (1 - 0.5^5) / (1 - 0.5)
= 19.375 m.
The answer to this question is 120winners
Answer:
7.834 × 10^-8
Step-by-step explanation:
= 7.834 × 10^-8
(scientific notation)
= 7.834e-8
(scientific e notation)
= 78.34 × 10^-9
(engineering notation)
(billionth; prefix nano- (n))
= 0.00000007834
(real number)
^ means the number after is exponent.
So it went from 1/3 full to 3/4 full when 10 gallons were put in, so.... what fraction is 10 gallons anyway? let's check the
difference.
if say, when full is "x" gallons,
120 - 22 = 98. 98 / 15 = 6.533333. Because you want the minimum, and he can't get paid during 0.53333 of a week, Tom must walk the dog for a minimum of 7 weeks.
