I believe you would multiply 6 and 13 together giving you 78. So Adrian can have 78 different CD combinations :)

When the graph rises one square for a run of one square, the slope is 2 km/(0.5 h) = 4 km/h. When the graph rises half that fast, the slope is 2 km/h. When the graph is horizontal, the slope is 0. The slope of the distance vs time curve is the speed.

  • S = 4 km/h, when 0 < t < 2 h
  • S = 0, when 2 h ≤ t < 2.5 h
  • S = 4 km/h, when 2.5 h ≤ t < 3 h
  • S = 0, when 3h ≤ t < 4 h
  • S = 2 km/h, when 4 h ≤ t < 5 h

Tony measures a drum stick and gets a length of 31 centimeters kate converts tony's measurements and gets 3.1 is her answer reas
laila [671]

Answer:

Kate has changed the unit of measurement from centimeters to decimeters.

Step-by-step explanation:

Tony measures a drum stick and the length is measured to be 31 centimeters.

Now, Kate converts Tony's measurements and gets 3.1.

Now, we know that 10 centimeters are equivalent to 1 decimeter.

Hence, 1 centimeter will be equivalent to 0.1 decimeters.

And, 31 centimeters will be equivalent to 31 × 0.1 = 3.1 decimeters.

So, Kate has changed the unit of measurement from centimeters to decimeters. (Answer)

Helps with this math problem please

First we are going to express both equation in terms of  y to compare their slopes:
For our first equation:
-x=1-y
-x-1=-y
y=x+1
For our second equation:
-1+y=x+2
y=x+3
So now we have our system of equations in terms of y:
\left \{ {{y=x+1} \atop {y=x+3}} \right.
Notice that the slope, the coefficient of x, in both equations is the same: 1, and if tow linear equations have the same slope, they are parallel.

We can conclude that we can classify the system of equations as parallel.
