Answer:
81mm
Step-by-step explanation:
the number of steps is small enough that we can simply list out each step
let the time elapsed be t and the original length be L ( = 1 mm)
when t = 0, L = 1mm
when t = 10, L = 3mm
when t = 20, L = 3 x 3 = 9mm
when t = 30, L = 9 x 3 = 27mm
when t = 40, L = 27 x 3 = 81mm
Hello from MrBillDoesMath!
Answer:
60
Discussion:
As JG bisects FJG,
FJG = GJH =>
2x + 4 = 3x-9 => subtract 2x from each side
4 = 3x -2x - 9 => simplify
4 = x - 9 => add 9 to both sides
4 + 9 = x
x = 13
Now, FJH =
FJG + GJH
(2x + 4) + (3x-9) =
5x -5 => substitute x 13
5(13) -5 =
65 - 5 =
60

Answer:
Improper: 2 42/9 proper: 6 6/9
Step-by-step explanation:
2 7/9 x 2/3
find the common denominator which is 9 so now we have,
2 7/9 x 2/9
find the numerator which is,
2 7/9 x 6/9
multiply
2 42/9
This fraction is improper so lets make it proper,
42 goes into 9 four times
so we have,
6/9 + 2 + 4
final answer,
6 6/9
