Step-by-step explanation:
X is 6*10=60 and therefore y will be 14*10 which gives us 140. So y=140
23
Step-by-step explanation:
angle DEF = 74 degrees.
well I would use sins but it's quite simple
Length of DE is 23, just like AB
Make each of these an improper fraction, which would be 7/2 and 4/3. You can multiply these to get 28 / 6, and then you simplify to get 14/3, and if you were trying to make it a mixed number, just do 4 2/3
This is the concept of arithmetic. To calculate the percentage of time life has existed we proceed as follows;
According to history:
The age of earth is 4.6 billion years
the age of life is as it appeared from unicellular is 3.8 billion years.
thus the percentage of the above will be:
3.8/4.6 x 100
=0.82609x100
=82.609%
