The fare for a taxi cab is $2.50 per passenger and $0.75 for each mile. A group of friends has $22.00

xeze [42]

For this case we have to:

x: Let the variable representing the number of people to travel in the group

y: Let the variable representing the number of miles traveled.

If friends only have $22 then we have the following inequality:

$2.50x + 0.75y \leq22$

Now, if there are three people in the group we have that $x = 3.$

$2.50 (3) + 0.75y \leq22\\7.5 + 0.75y \leq22\\0.75y \leq22-7.5\\0.75y \leq14.5\\y\leq \frac {14.5} {0.75}\\y\leq19.33$

The taxi can travel a maximum of 19.33 miles.

On the other hand, if the group wants to travel 10 miles then we have to y = 10.

$2.50x + 0.75 (10) \leq22\\2.50x + 7.5 \leq22\\2.50x \leq22-7.5\\2.50x \leq14.5\\x\leq \frac {14.5} {2.50}\\x \leq5.8$

Thus, they could travel a maximum of 5 people.

ANswer:

$2.50x + 0.75y \leq22$

Traveling 3 people, the taxi can travel a maximum of 19.33 miles

Traveling 10 miles, a maximum of 5 people can travel

1. A quadrilateral has vertices A(0,0), B(8,0),C(7,5), and

babunello [35]

The formula for the distance between two points is

$d(A,B) = \sqrt{(A_x-B_x)^2+(A_y-B_y)^2}$

Note that, if two points have one coordinate in common, this formula simplifies to

$d(A,B) = |A_x-B_x|,\quad d(A,B)=|A_y-B_y|$

(the first if they share the y coordinate, the second if they share the x coordinate).

So, these are the lengths of the sides:

$d(A,B)=|8-0|=8$

(because they share the y coordinate)

$d(B,C) = \sqrt{(8-7)^2+(0-5)^2}=\sqrt{1+25}=\sqrt{26}$

(standard formula)

$d(C,D)=|7-3|=4$

(because they share the y coordinate)

$d(A,D) = \sqrt{(0-3)^2+(0-5)^2}=\sqrt{9+25}=\sqrt{34}$
