A taxi ride costs $3.50 plus $2.50 per mile driven. If Sasha has $37 in cash , what is the greatest whole number of miles she ca
Margaret [11]
Create an equation for the total costs of driving x miles: 3.50 + 2.50x


since Sasha has $37, the equation would become: 3.50 + 2.50x = $37

subtract 3.50 from both sides: 2.50x = 33.50

divide 2.50 on both sides: x = 13.4


since the problem is asking for the greatest whole number of miles, you have to round down and the answer would be: 13 miles.

Use an equation to find the value of k so that the line that passes through (-2,k) and (2,0) has a slope of m=-1
Dima020 [189]

Answer:

The value of k is 4.

Step-by-step explanation:

To find the missing coordinate, we can use the slope equation and plug in all known values.

m(slope) = (y2 - y1)/(x2 - x1)

-1 = (k - 0)/(-2 - 2)

-1 = k/-4

Now we can solve using cross multiplication.

-1 = k/-4

k*1 = -1*-4

k = 4

Find the missing part.
sveta [45]

Answer:

The answer is a = \frac{15}{4}

Step-by-step explanation:

We have to:

cos(\theta) = \frac{adjacent\ side}{hypotenuse}

So, if we take the 60 degree angle of the smallest triangle, we have to:

cos(60) = \frac{a}{x}

We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:

sin(30) = \frac{x}{15}\\\\x =\frac{15}{2}

Then:

cos(60) = \frac{a}{\frac{15}{2}}

a = cos(60)\frac{15}{2}

a = \frac{15}{4}
