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 distance $d$ (in mi) driven by a car traveling at a speed of $v$ miles per hour for $t$ hours is given by $$d=v t$$ If the car is driven at 70 milh for 3.5 $\mathrm{h}$ , how far has it traveled?

Using Models Use the model given to answer the questions about the object or process being modeled. An ocean diver models the pressure $P$ ( in $\mathrm{lb} / \mathrm{in}^{2} )$ ) at depth $d$ (in ft) by $$P=14.7+0.45 d$$ (a) Make a table that gives the pressure for each 10 -ft change in depth, from a depth of 0 ft to 60 $\mathrm{ft}$ . (b) If the pressure is $30 \mathrm{lb} / \mathrm{in}^{2},$ what is the depth?

in this problem, we're being asked to find each product. So remember when multiplying rational numbers when two numbers have the same sign, your answer was positive on when two numbers have different signs, their answer would be negative. So let's start with part A. We have eight times negative three. So first, we're gonna start by multiplying eight times three, which is 24. And because one numbers positive and the others negative are result will be negative. So our answer will be negative. 24. Now, for part B, you have negative five times negative. Four. Remember when the parentheses air touching? That means multiplication. So first, we're going to multiply five times four, which is 20. And because both numbers air negative, the result will be positive. So negative five times negative for is positive 20. And lastly, part C. We have zero times negative too. Well, zero times two is equal to zero. Now this is where some people might get a little confused. Zero is never positive and negative. So whenever you multiply in your answer zero you won't worry about the sign because again zero is neutral's not positive nor negative. So zero times negative two will simply just be zero
