$3.99
$4.50
$6.00

3 answers

The total cost of the three items is $3.99 + $4.50 + $6.00 = $<<3.99+4.50+6.00=14.49>>14.49.
The principal bought these items for 22 teachers, so the total amount spent on these items is $14.49 x 22 = $<<14.49*22=318.78>>318.78. Answer: \boxed{318.78}.
List the percentages of the following found in your DNA molecule.
a. % Adenine: 30
b. % Guanine: 20
c. % Thymine: 30
d. % Cytosine: 20
e. # Hydrogen Bonds: ______

If a strand of DNA has 20% thymine, what percent of guanine will it contain?
If a strand of DNA has 20% thymine, then the percentage of guanine it contains will also be 20%. This is because in DNA, adenine always pairs with thymine and guanine always pairs with cytosine. Therefore, the percentages of adenine and thymine are always equal, as are the percentages of guanine and cytosine. So, if the percentage of thymine is 20%, the percentage of guanine will also be 20%.
