Whats the model because 7/9 × 3/4= 7/12 which also equals to 21/36
as 7/12 is the simplified version of 21/36 but then for c 4×9 =36 so I'm a bit confused my self but here's a bit of a start
Answer:
Yes you are correct. 9/20 is correct.
Step-by-step explanation:
7
/10 - 1
/4 =
7 * 2 / 10*2
1 * 5 / 4 * 5 = 14
/20 -5
/20 =9
/20
Answer:
13.6 ft
Step-by-step explanation:
The geometric sequence of arc lengths can be described by ...
f(n) = a·b^n
We have (n, f(n)) = (3, 20) and (7, 12). Using these values, we can find the common ratio (b):
20 = a·b^3
12 = a·b^7
Then ...
12/20 = (a·b^7)/(a·b^3) = b^4 = 3/5
We want the 6th term, which we can get from the 7th term by multiplying by b^-1.
b^(-1) = (b^4)^(-1/4) = (3/5)^(-1/4) = √(√(5/3)) ≈ 1.13622
Then the 6th swing had an arc length of ...
f(6) = f(7)·b^-1
f(6) = (12 ft)(1.13622) ≈ 13.63 ft ≈ 13.6 ft
Answer:
1 week, 14 days, 24 hours = 1 day,
= 4 days + 7 days + 10 hours + 16 hours
= 11 days + 26 hours
= 11 days 26 hours
