The number shown here is written in scientific notation since it’s composed of a decimal that is between 1 and 10 in this case 2.98 and a power of 10 in this case 10 to the 7th power. Therefore, this number is written in proper scientific notation.
Answer:
a = 8 m
Step-by-step explanation:
Since, given is an isosceles right triangle.
So, by Pythagoras theorem:

I hope this picture helps, but next time try to chose a number to cancel out the fraction. Example, y=1/3x+4 chose 3,6,9 and other multiples of 3.
The total to this would be $1,389.93 because $1,299 + 7% = $1,389.93
The value of 7 in 7,283 is 10 times the value of 7 in 2,783
