Answer:

n = 8.

Step-by-step explanation:

I am assuming that the sum is 255.

The last term is 128 and the common ratio is 2 so we can work backwards until we reach a sum of 255.

Term n = 128 so the previous term must be 128/2 = 64.

So following this pattern we have:

128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255.

So we see that n = 8.

I need help with a math question that is 0.1x = 5/y
BabaBlast [244]
Unfortunately you have not included the directions.  Are you supposed to solve for x?  or for y?

Suppose the directions say, "Solve for x."  Then, clear out the decimal fraction by mult. both sides of the given equation by 10.  This will give you the solution, that is, a formula for x in terms of y.

I REALLY NEED HELP ON 40 and 41, 50 POINTS

Question 40 is D because from looking at the graph, its is symmetrical and the mean is the average, which usually the middle of the graph, so is the median. The median and mean would be within the 2.1-3 category because its the middle of the graph.

Question 41 is B because every pound is 16 ounces. If you multiply 16 and 12.5, you'll get 200.
