I believe the answer is d.
1. Subtract 1/3 from 7/9.
1/3 and 7/9 : Both denominators of 3 and 9 go into 9.
2. 1/3* 3 = 3/9 7/9*1 = 7/9
3.3/9 - 7/9 = 4/9 OR 2 1/9
Answer:
415.7 mph or mph
Step-by-step explanation:
Did you make a sketch and got a right-angled triangle?
let the horizontal distance between the plane and the station be x miles
let the distance between the plane and the station be y miles
given: dx/dt = 480 mph
find: dy/dt when y = 6
y^2 = x^2 + 3^2
when y = 6
36 = x^2 + 9
x = √27
2y dy/dt = 2x dx/dt
dy/dt = (x/y)dx/dt
= √27(480)/6
= 415.7 mph or 416 mph
i think i hope this helps

You would do 54 minus 35 because the line is a total of 54 units and the part of the line that isn’t x is 35 units so you subtract them to get 19 units which is the length of the line that’s left.
