Answer: 13 cm^3
Step-by-step explanation:
The volume of a rectangular prism is the height*width*length.
3 1/4 as a decimal is 3.25.
Now we can plug in the given values into the formula for the volume.
Therefore, the volume = 3.25 cm * 4 cm * 1 cm
= 13 cm^3
Answer:
A
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
BC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )
BC = 
= 15 → A
Answer:
B
Step-by-step explanation:
y = mx + b
The slope is m.
If it was anything other than 0, the line would have an x in it. The line does not have an x associated with it.
The equation of the line is y = 1
The slope must be 0.
