Answer:
The bus will take 81 minutes to complete the trip.
Step-by-step explanation:
To determine how many minutes will the bus take to complete the trip if a bus completes half a trip at 40 km per hour and the other half at 50 km per hour, and the whole trip was 60 km, the following calculation must be performed:
60/2 = 30
30/40 = 3/4 of an hour = 45 minutes
30/50 = 3/5 of an hour = 36 minutes
45 + 36 = 81
Therefore, the bus will take 81 minutes to complete the trip.
Answer:
16320 cubes are needed to fill the rectangular prism.
Step-by-step explanation:
Given : A rectangular prism has a length of 12 in., a width of 5 in., and a height of 
in.
The prism is filled with cubes that have edge lengths of 
in.
To find : How many cubes are needed to fill the rectangular prism?
Solution :
A rectangular prism has
Length of 12 in.
Width of 5 in.

in.
Volume of rectangular prism is 
A cube has length of in.
Volume of cube is 
Cubes are needed to fill the rectangular prism is
Therefore, 16320 cubes are needed to fill the rectangular prism.
Answer:
A linear function has a constant rate of change. A nonlinear function does not
Also, Lnear functions show a straight line when they are graphed and nonlinear functions don't.
My advice is to graph it and look at the points.

The value of h is h = -1.5
Step-by-step explanation:
The quadratic equation is represented by a parabola, the vertex form of the equation is y = a(x - h)² + k, where
- (h , k) are the coordinates of its vertex point
- a is the coefficient of x²
∵ The graph is a parabola opens up
∵ It has a vertex at (-1.5, 0)
∵ The vertex of the parabola is (h , k)
∴ h = -1.5 and k = 0
∵ The graph shows f(x) = (x - h)²
∵ The coordinates of the vertex are (h , k)
∵ h = -1.5 and k = 0
∴ h = -1.5
The value of h is h = -1.5
