An air traffic controler is tracking two planes. To start, Plane A was at an altitude of 990 meters, and Plane B was at an altitude of 1476 meters. Plane A ls losing altitude at 18 meters per second, and Plane B is losing altitude at 27 meters per second.

Let x be the number of seconds that have passed.

(a) For each plane, write an expression for the altitude of the plane
after x seconds.
Altitude of Plane A (In meters) =
Altitude of Plane B (in meters) =

(B) Write an equation to show when the two planes would be at the same altitude

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

40% off the regular price is the correct answer.

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
