Any polygon with interior angles that add up to 540 must have 5 sides and 5 corners (a pentagon). Assuming it is a regular pentagon, you need to work out what 1/5 of 540 is, which is the same as dividing it by 5. 540/5 = 108. This is the number of degrees in one interior angle of a regular pentagon.
Lol thank you. The easiest way is to read the passage thoroughly since the answe is always in the passage! And make sure to rule out answers which aren't even close to being an answer, in this case I rules out A and C which left me to only think about B and D which made it easier to find the answer.
This problem is pretty simple. Since we cannot divide this we can change the division sign into a multiplication, but to do this we need to also take the reciprocal of 2/3, which means we flip th number so it becomes 3/2. Now we can simply multiply. (1/4)*(3/2) which should give you 3/8
Let multiplicative factor be x Then amount of walnuts to buy = 1(x), or x Amount of almonds to buy = 2(x), or 2x Amount of raisins to buy = 3(x), or 3x Cost of x lbs of walnuts: 12x Cost of 2x lbs of almonds: 2x(9), or 18x Cost of 3x lbs of raisins: 3x(5), or 15x We then have: 12x + 18x + 15x = 15 45x = 15 x, or multiplicative factor 15/45 , or 1/3 Amount of walnuts to be purchased: x, or lb Amount of almonds to be purchased: 2x, or 2/3 lb Amount of raisins to be purchased: 3x, or , or 1 lb Amount of trail mix that can be made with $15 2 or lbs
