Answer:
an = 1/4 * an-1
a1 = 2
Step-by-step explanation:
2, 1/2, 1/8, 1/32
To find the common ratio, take the second term and divide by the first term
1/2 ÷ 2
1/2 * 1/2
1/4
The common ratio is 1/4
1/2 * 1/4 = 1/8 and 1/8 *1/4 = 1/32
The first term is a1 so a1 = 2
an = the common ratio * an-1
an = 1/4 * an-1
Answer:
D. 4 jump ropes, 3 people, 15 friends
Step-by-step explanation:
In order to answer the question how many friends could play, you need to be able to determine the smaller of ...
- (number of ropes) × (friends per rope)
- number of friends
You can find the first of these numbers using the values of answer A, but if the number of Franklin's friends is smaller than 12, then you need to know that in order to properly answer the question. Hence, we believe you need to know ...
- the number of jump ropes
- the number of friends per rope
- the number of friends

Answer:
860 beads
Step-by-step explanation:
60 times 77=4620
40 times 113=4520
4620+4520=9140
10000-9140=860
Make x the same in both so
12x+ 4y=72
12x+6y=30
Now the 12x cancel eachother out so
Difference between 6y and 4y is 2y
Difference between 30 and 72 is -42
2y must equal -42
Y = -21
Substitute -21 into the equation
X = 13
