Answer:
I say "ok" to my parents when they ask a question as a joke, but that has happened to me and it's just annoying. If you don't find it funny then don't laugh at all and don't say anything-
Each element is 2/3 times the previous one, so that's a geometric sequence.
6×(2/3)=4, 4×(2/3)=8/3, 8/3×(2/3)=16/9, 16/9×(2/3)=32/27
Answer: 6, 4, 8/3, 16/9, 32/27
This is a simple equation.
The equation is y = 1.6x with y being the miles and x being the kilometers.
Lets plug the kilometers in.
Y=1.6(7.7)
1.6 * 7.7 = 12.32
12.32 miles is equal to 7.7 kilometers
HOWEVER
There are about .6 miles in a kilometer, so if you typed this wrong I don't know.
It is still the same concept.
Y = .6x
Y = .6(7.7)
.6 * 7.7 = 4.8
In this case there are 4.8 miles in 7.7 kilometers
Z=118 as vertically opposite angles are the same
x= (8x-50)
It should be 6, radius is half of the circumference (6/3=2).
