Einstein went on to present his findings mathematically: energy (E) equals mass (m) times the speed of light (c) squared (2), or E=mc2. The secret the equation revealed—that mass and energy are different forms of the same thing—had eluded scientists for centuries.
Answer:
c = 1.29s + 2
Step-by-step explanation:
c represents the total cost
s represents the number of songs downloaded
1.29 represents the cost charged for every song downloaded
2 represents the initial cost to download the app
Time taken to fill the bathtub is 8 min
time taken to drain the bathtub is 12 min
fraction of bathtub filled in 1 hour=1/8
fraction of bathtub drained in 1 hour=1/12
fraction that will be filled in a minute given that both taps are opened at he same time:
1/8-1/12
=1/24
thus time taken for the bathtub to be filled is 24 min
What is the question? if you are looking for the sides 2 sides are 40 and the other 2 are 20.
