Acertain nyc taxi driver has decided to start charging a rate of r cents per person per mile. how much, in dollars, would it cost 3 people to travel x miles if he decides to give them a 50% discount?
a. 3xr/2
b. 3x/200r
c. 3r/200x
d. 3xr/200
e. xr/600

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

For 3 people the cost is

Discount is 50%, so we divide by 2

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
