She ran 20% of the journey
20% x 9km = 0.2 x 9 = 1.8 km
Answer: She ran 1.8 km
Answer:
a(10) = 3^9 = 19683
Step-by-step explanation:
In this sequence each new term is equal to 3 times the previous term. Thus, 3 is the common ratio. The first term is 1.
The general formula for the nth term of a geometric sequence i
a(n) = a(1)*r^(n -1), where r is the common ratio.
Here, a(n) = 1*3^(n - 1), and so
the 10th term is
a(10) = 1*3^(10 - 1), or
a(10) = 3^9 = 19683
So you have 9x-10 and x= -5
9(-5)-10
-45-10= -55
Your answer would be -55
Answer:
27/7 or 3 6/7
Step-by-step explanation:
3/7 divided by 1/9 = 27/7
rounded to 3
