The base charge of a cab in New York is $2.50 as soon as you enter the cab. There is an additional charge of $2.50 per miles tra
Verdich [7]

Answer:

7 miles

Step-by-step explanation:

You have total of $20

We subtract $2.50 from it since it is the base charge, so now we have:

20 - 2.5 = $17.50

This is for the number of miles at $2.50 PER MILE. To find the number of miles we can travel for this, we have to divide the amount we have (17.5) by the rate per mile (2.5), so we have:

17.5/2.7 = 7

So for a total of $20, we can travel 7 miles (without tip)

Four pounds of flour cost $2.60 how much flour do you get per dollar? round your answer to the nearest hundredth, if necessary.
gogolik [260]

Since 4 pounds of flour costs $2.60, we have that:

\begin{gathered} 4\text{pounds}\to2.60 \\ x\to1 \end{gathered}

Where x is the amount of flour you get for 1 dollar.

We can rewrite the expression above as follows:

\begin{gathered} \frac{4\text{pounds}}{2.60}=\frac{x\text{ pounds}}{1} \\ \Rightarrow x\text{ pounds}=\frac{4pounds}{2.6}=1.53846\ldots \\ \Rightarrow x\approx1.54 \end{gathered}

Then, we get 1.54 pounds of flour per dollar

What is the slope of a line that is perpendicular to the lien whose equation is 2y=3x-1
bixtya [17]

<u>Answer:</u>

-2/3

<u>Step-by-step explanation:</u>

We are to find the slope of a line which is perpendicular of a line with an equation 2y=3x-1.

We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.

So writing the given equation of a line in the slope intercept form:

2y=3x-1 ---> y=\frac{3}{2} x-\frac{1}{2}

Here the slope of this line is \frac{3}{2} so the slope of a line which is perpendicular to the given line will be -\frac{2}{3}.
