Answer:

The angle from the centre of Ann's slice is 60 degrees.

Step-by-step explanation:

If the size of the slices is proportional to the ages of the children eating the cake, then the sum of their ages equal to 360 degrees (since the cake is a circle).

So to work out the angle of Ann's portion, we find a fraction for Ann's age over the total of all of their ages. So:

5/(5 + 10 + 15) = 5/30

Now since we know their ages are proportional to the slices of cake, we can find the same value for the fraction 5/30 that is out of 360 to work out the angle. Let's call the angle representing Ann's slice x. So know we can create an equation:

5/30 = x/ 360

5/30 * 360 = x

x = 60

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.
