Step-by-step explanation:
The two planes are flying on the two legs of a right triangle.
The straight distance between them is the hypotenuse of the triangle.
Since the speeds are in mph, let's work the time in hours.
Call the time 'H' that we're looking for.
It's the number of hours after they both take off that they're 650 miles apart.
After 'H' hours, the first plane has gone 500H miles north.
After 'H' hours, the second plane has gone 1200H miles east.
After 'H' hours, they are 650 miles apart.
Do you remember this for a right triangle ? ==> A² + B² = C²
(500H)² + (1200H)² = (650)²
250,000H² + 1,440,000H² = 422,500
1,690,000 H² = 422,500
H² = (422,500) / (1,690,000) = 0.25
H = √0.25 = 1/2 hour = 30 minutes
I don't know honey, but I think it can be the 2nd choice, the answer...
50 miles/1 hour = ? miles/200 miles.
I hope I helped and goodluck :)
U have a solid line...means there is an equal sign in the problem...so that eliminates 2 of them right away...so A and D are incorrect
it is shaded below the line....this means it is less then...that eliminates option C leaving u with only one answer choice
so ur answer is : B. y is less then or equal to x
