You can do this !

Since d=3, take your pencil and write the fraction again,
except wherever 'd' appears, write a '3' there instead.

Then you'll have a fraction with nothing but numbers in it, and
you can easily simplify and find the value of the fraction.

I did it in my head as I was looking over the picture, and
I found that the value of the fraction is between 5 and 10.
I don't want to just hand you the answer, because I know
that you can do it.

mafiozo [28]

Answer:

3.3 gallons

(11/4)/x = (10/3)/4 (cross multiplication)

(11/4)*(4/1)=44/4=11

11/(10/3) = ( 11/1 ) * (3/10) = 33/10 = 3.3 gallons

Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal: (8.1*10^-4)^2
AfilCa [17]
<h3>Answer:</h3>
  • the result in scientific notation is 6.561×10⁻⁷
  • the result as a decimal is 0.000 000 656 1
<h3>Explanation:</h3>

The rules of exponents say the exponent outside parentheses applies to each factor inside parentheses.

... (8.1*10^-4)^2 = 8.1^2 × (10^-4)^2

... = 65.61 × 10^-8

... = 6.561 × 10^-7 . . . . adjust to scientific notation with one digit left of the decimal point

The exponent of -7 means the decimal point in the decimal number is 7 places to the left of where it is in scientific notation. That is ...

... 6.561 × 10^-7 = 0.0000006561
