Answer:
After 900 minutes
Step-by-step explanation:
when we convert the velocities of the ships into miles/ min we get


The equations determining the distances of the ships from the port M (set at x=0) are
(for 45mph ship)
(for 36mph ship)
The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
Answer:
one solution
(second option listed)
Step-by-step explanation:
We can that these two lines, each representing one equation/function, only meet at one specific value.
In a system of equations, we are essentially looking for a solution that works for both equations.
So, if both lines share a point/value (meaning they intersect), that point is a solution to the system of equations.
Because these lines only overlap at one point, this system of equations has one solution.

Answer:</h2><h2>
The actual height of the building = 36 feet.</h2>
Step-by-step explanation:
By blue print conversion,
2 inches = 8 feet
Therefore, 1 inch =
= 4 feet
1 inch = 4 feet
The height of the building on the blueprint = 9 inches
The actual height of the building = 9 * 4 = 36 feet.
