3 \frac{1}{2} r = 28 \\  \frac{7}{2} r = 28 \\  \frac{ \frac{7}{2} }{ \frac{7}{2} } r =  \frac{28}{ \frac{7}{2} }  \\ r =  \frac{ \frac{56}{2} }{ \frac{7}{2} }  \\ r= \frac{56}{7}

1 \frac{1}{2} c =6 \\  \frac{3}{2} c= \frac{12}{2}  \\  \frac{ \frac{3}{2} }{ \frac{3}{2} } c= \frac{ \frac{12}{2} }{ \frac{3}{2} }  \\ c= \frac{ \frac{12}{2} }{ \frac{3}{2} } = \frac{12}{3} =4 \\ c=4

B. If some amount of water contains 1400 oxygen atoms, how many hydrogen atoms does it contain?
Genrish500 [490]

Answer:

B: 2800 hydrogen atoms

C: 6760 hydrogen atoms

D: y=amount of oxygen atoms*2

Step-by-step explanation:

B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.

C: Same thing as B. 3380*2=6760

D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

Rationalize the denominator and simplify.
Irina18 [472]

Answer:

\frac{3 \sqrt{2}  - 2 \sqrt{3} }{3 \sqrt{2}  + 2  \sqrt{3}  }   \times  \frac{3 \sqrt{2}  - 2 \sqrt{3} }{3 \sqrt{2}  - 2 \sqrt{3} }  \\  \\  =   \frac{18 + 12 - 12 \sqrt{6} }{18 - 12}  \\  \\  =  \frac{30 - 12 \sqrt{6} }{6}  \\  \\  = 5 - 2 \sqrt{6}
