Answer:
13 or 13.125 you have to look at your notes to see which it is. Personally I would take 13. Try that first.
Step-by-step explanation:
Be careful how you interpret this question. It reads like this.
3:8 :: x:35
In other words, the 8 and 35 females goes together.
Set this up as a proportion
3/8 = x / 35 Cross multiply
3*35 = 8x Combine the left
105 = 8x Switch
8x = 105 Divide by 8
x = 105 / 8 get the answer
x = 13.125 You cannot have 1/8 of a person. So what are you going to do?
You have to round down. x = 13. How close is this
13/35 = 0.371 as apposed to 0.375 which is what 3/8 is.
That was very inspirational, I almost cried.
Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.
