Not sure if there're any answer choices of some sort,
but if the angle a and angle b are supplementary, that means when you add their measures together they must equal 180.
Answer:

Step-by-step explanation:
Given that,
Mass of a sample, m = 12 g
Heat absobed by the sample, Q = 96 J
It was heated from 20°C to 40°C.
We need to find the specific heat of a material. The heat absorbed by a sample is given by :

So, the specific heat of the material is
.
If 0.25 in on a drawing is 12 ft in real life, than 1 in on the drawing is 48 ft in real life.
Just divide 15 by 48
15/48=0.3125
So the length of 15 in real life to a drawing is 0.3125 inches.
Answer:
(-4, -3)
Step-by-step explanation:
That's Correct!
x + 4 shifts the origin 4 left
y + 3 shifts the origin 3 down
(-4, -3)
