Using Models Use the model given to answer the questions about the object or process being modeled. The gas mileage $M($ in milgal) of a car is modeled by $M=N / G,$ where $N$ is the number of miles driven and $G$ is the number of gallons of gas used. (a) Find the gas mileage $M$ for a car that drove 240 mi on 8 gal of gas. (b) $A$ car with a gas mileage $M=25$ mi/gal is driven 175 mi. How many gallons of gas are used?

Using Models Use the model given to answer the questions about the object or process being modeled. The portion of a floating iceberg that is below the water sur- face is much larger than the portion above the surface. The total volume $V$ of an iceberg is modeled by $$V=9.5 S$$ where $S$ is the volume showing above the surface. (a) Find the total volume of an iceberg if the volume show- ing above the surface is 4 $\mathrm{km}^{3}$ . (b) Find the volume showing above the surface for an ice- berg with total volume 19 $\mathrm{km}^{3}$ .

point p, which is the coordinates 0.6 and 0.8 to find the sign and co sign of an angle that is drawn you with this point. Uh, this point is actually going allow the terminal side of the angle, which means, um that it's the side that's moving and it's gonna that means there's gonna be an r. It would equal one. We can get our sign and cosign from our points. Our son is r y coordinate. So that's gonna be 0.8 and our cosign is our X coordinate, which will be 0.6.
