Answer:
144
Step-by-step explanation:
JG= 72
JG is half of HI so
72 x 2 = 144

Answer: There are 24 ways.
Step-by-step explanation:
All the numbers are divisible by 11, so divide all the numbers by 11 to make the problem simpler: Jo climbs a flight of 6 stairs. Jo can take the stairs 1, 2, or 3 at a time.
A recursive approach can now solve this problem. The number of ways to climb one stair is 1. There are two ways to climb 2 stairs: (1, 1) or (2). For 3 stairs, there are 4 ways: (1, 1, 1), (1, 2), (2, 1), and (3). Extending this pattern, there are 1+2+4 = 7 ways to climb up 4 stairs, 2+4+7 = 13 ways to climb up 5 stairs, and 4+7+13 = 24 ways to get up 6 stairs.
Answer:
the 2nd one
Step-by-step explanation:
just substitue values.
Answer:
5
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
The expression inside the summation is
4 ← the nth term of a geometric sequence
with a = 4 and r = , then
=
=
= ( )
=
= 5
