Answer:
the statement that is not supported by the trend in the scatter plot is d) each additional pound adds about one hour of cooking time.
Roy: y=150-1.5x
Luis: y=200-2.5x
150-1.5x=200-2.5x
150=200-x
-50=-x
50=x
So in 50 weeks, Roy and Luis will weigh the same at 75 pounds each.

Answer:
1.68 km
Step-by-step explanation:
You want the horizontal distance (on the ground) from beneath the helicopter to the vertex of the 37 degree angle. The hypotenuse is given and is 2.1 km.
We want to find the horizontal distance when we already know the angle and the hypotenuse.
That horizontal distance could be called 'x.' Then:
x/r = adj/hyp = cos 37 degrees, which becomes adj = (2.1 km)cos 37 degrees, which is found using a calculator: adj = (2.1 km)(0.7987) = 1.68 km
They used the river for trade, transportation, and agriculture
