E=mc^2 is one of the most recognizable equations in the world. In this task, you’ll attempt to understand it better. Let’s start with what the letters mean. The letter E stands for energy, the letter m stands for mass, and the letter c stands for the speed of light. The meaning of this equation is that you can completely convert mass into energy.
c^2 = E/m
c = (E/m)^(1/2)
Answer:
Step-by-step explanation:
40 because 15×4 is 60 and there is 60 minutes in an hour
Answer:
A = 56 in²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂ )
h is the perpendicular height between bases and b₁, b₂ the bases
here h = 7 , b₁ = 10 , b₂ = 6 , then
A = × 7 × (10 + 6) = 3.5 × 16 = 56 in²
