Answer:
y =36
z= 54
Step-by-step explanation:
The angles 3y and 2y form a straight line, so they add to 180 degrees.
3y+2y =180
5y = 180
Divide each side by 5
5y/5= 180/5
y =36
The angles z, y, from a 90 degree angle
z+y =90
z+36 = 90
Subtract 36 from each side
z+36-36 = 90-36
z = 54

Answer:

Step-by-step explanation:
Recall that the volume of a cube is given by:

Where <em>s</em> is the side length of the cube.
The edges of the cube has an original length of 2.25 feet. It increases by 1.25 feet per hour. In other words, the length <em>s</em> after <em>h</em> hours can be modeled by the equation:

Substitute. Hence, our function is:
