Answer:
let us consider the full weight to be x.
Step-by-step explanation:
1.25% of x = 5
1.25/100 * x = 5
x = 5*100/1.25
x=5*100*100/125
x=100*100/25
x=4*100
x=400
.: full weight would be 400grams.
24 - 16 = 8
36 - 24 = 12
54 - 36 = 18
So, obviously, this isn't an arithmetic sequence.
24/16 = 3/2
36/24 = 3/2
54/36 = 3/2
Aha! This is a geometric sequence.
Now, let's find the 7th term in this sequence!
We're trying to solve for a_7.
We know that a_1 is 16
We know that n = 7
We know that r = 3/2 or 1.5
Plug it in!
The seventh term is
182.25
Septimus heap it's a good book!!!!
Answer:
See below
Step-by-step explanation:
I am not sure about number 22. I think that they are asking you to apply the same rules to the point (4, -7), if that is what they mean, the answer is (8,10)
The answer is 1 and 1/2 feet
