Multiply 2.25 by each answer and 750 and write down the total next multiply 3.25 by each answer lowest to highest once you get a product that is higher than you writen down answer play around with the numbers until you get the exact amount D 760 2.25 times 760 is 2460 by 3.25 its 2570 you save 10 dalloars and are able to pay for the food and band
Angles are measures of turn. A complete turn is called a perigon angle or full angle which measures 360°. A half (1/2) turn is called a straight angle, because it looks like a straight line with a dot (the vertex) in the middle, its measure is 180°. The rays are the two halves of a line and they point in opposite directions.
