A car with 15 gallons of gasoline drives 420 miles until the tank is empty. Write a linear equation that describes the amount of

storchak [24]

Answer:

$y = -\dfrac{1}{28}x + 15$

Step-by-step explanation:

The car uses 15 gallons of gasoline to drive 420 miles.

(15 gal)/(420 mi) = 1/28 gal/mi

The car uses 1/28 gallon of gasoline per mile.

y = mx + b

When x = 0, at the start of the drive, the car has 15 gallons of gasoline.

y = mx + 15

Then for every mile it travels, the amount of gasoline goes down by 1/28 gal. For x miles of travel, it uses 1/28 * x gallons of gasoline.

$y = -\dfrac{1}{28}x + 15$

Check the picture below, it hits the ground when y = 0.

$\bf ~~~~~~\textit{initial velocity}\\\\
\begin{array}{llll}
~~~~~~\textit{in feet}\\\\
h(t) = -16t^2+v_ot+h_o \\\\
\end{array} 
\quad 
\begin{cases}
v_o=\stackrel{0}{\textit{initial velocity of the object}}\\\\
h_o=\stackrel{162}{\textit{initial height of the object}}\\\\
h=\stackrel{}{\textit{height of the object at "t" seconds}}
\end{cases}
\\\\\\
h(t)=-16t^2+0t+162\implies 0=-16t^2+162\implies 16t^2=162
\\\\\\
t=\cfrac{162}{16}\implies t=\cfrac{81}{8}\implies t=10\frac{1}{8}$

2/5 divided by 1/3 equals

aniked [119]

Answer:

6/5, or 1 1/5

Step-by-step explanation:

I use a method called KCF, which means Keep Change Flip. Here is your current expression: 2/5 / 1/3. First, keep the first fraction. Next, change the sign into a multiplication symbol. Now, you have 2/5 x 1/3. Finally, flip the last fraction into 3/1. Now, this is your expression: 2/5 x 3/1. Multiply numerator by numerator, denominator by denominator. Your final answer is 6/5, or 1 1/5 simplified.
