Marie plays the state lottery. During the lotteries in June, she lost $10, won $20, lost $8, lost $12, and won $25. What was the net result of her playing?

Her net result is +$15.

Step-by-step explanation:

If Marie lost then it would be a negative sign and if she won then it would be a positive sign.  For this case add the ones she lost which would total $30 and add the ones she won which would total $45.  Subtract the money she won with the money she lost to get a net result of +$15.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
