A. mcdonald's worldwide revenue is 24.85 billion dollars while its u. s. revenue is 8.69 billion dollars. what percent of the worldwide revenue is coming from the u. s.? round to the nearest tenth percent.
b. mcdonalds' famous arches are parabolas. the two parabolas are identical. either one of the parabolas can be modeled by the quadratic equation (all measurements are in feet):

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

the answer is 8/21

hope this
