d) 58 you said find the angle that is double sin25 (not sin50) so 2 x sin 25 gets you .84523 find what angle that is using inverse sin sin^-1 (.84523) = 57.697

Number four is actually D

The car is travelling 43ft/sec and decelerating at 5ft/s so we can assume it takes 43/5 seconds to stop. The car is slowing down constantly so the average speed of the car can be determined by 43/2 and then multiplying by the time it takes to stop the car we can find how many feet the car traveled before it stopped. (43/2 times 43/5 = 184.9 ft.)

A chemistry experiment needed 12.45 grams of chemical to produce one liter of a gas. If Zoe wanted 24 liters of gas, how many kilograms of the chemical will she need?

(18ml)(.265M)/1 mole=(25ml)(xM)/6mole xM=1.14M
