A certain NYC taxi driver has decided to start charging a rate of r cents per person per mile. How much, in dollars, would it co
katrin2010 [14]

Answer:

\frac{3xr}{200}

Step-by-step explanation:

A certain NYC taxi driver has decided to start charging a rate of r cents per person per mile

rate is cents . convert it in to dollars

1 cent = 1/100 dollars

r cents =  r/100 dollars

Each people travels x miles

cost is \frac{r}{100} \cdot x

For 3 people the cost is

3\frac{r}{100} \cdot x

Discount is 50%, so we divide by 2

\frac{3\frac{r}{100} \cdot x}{2} =\frac{3xr}{200}

Find the value of x in the isosceles triangle shown
Nat2105 [25]

Answer:

x = 8√5

Step-by-step explanation:

The large triangle is divided into two smaller ones.  The right one has one leg of length 8, one leg of length x/2, and hypotenuse of length √80.

Appling the Pythagorean Theorem, we can find x:

8² + (x/2)² = (√80)²,

or:                              x^2

64 + x^2/4 = 80, or  ------- = 80

                                    4

Then x^2 = 320 = 64*5.  Taking the square root of both sides, we get:

x = 8√5
