Answer:
-138
Step-by-step explanation:
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.
Answer: D) 32.8
=======================================================
Work Shown:
We'll apply the tangent ratio
tan(angle) = opposite/adjacent
tan(64) = x/16
16*tan(64) = x
x = 16*tan(64)
x = 32.8048614652688
x = 32.8
Make sure your calculator is in degree mode. One way to check is to compute tan(45) and you should get 1 as a result.
Answer:
Step-by-step explanation:
side of each of square is 6^2 - 4^2 = 36-16 = 20 = 2√5 = 4.47 = 4.5 approximately
diagonal is square root of 20+ 20 = square root of 40 = 6.32
