Lines of symmetry are lines that are the same but opposite to each other. For example, a rectangle has 2 lines of symmetry since it has 4 sides and 2 groups of symmetrical lines.
This shape is an octagon, which has 8 sides and 4 groups of symmetrical lines.

So the answer is C. 4.

Answer:

5.45%

Step-by-step explanation:

To find info of a 15 year old male, you look at the Age Group of 14 - 18, beside Male.

The RDA of Iron is given as 11 mg

From a 8 oz glass of grape juice, he gets 0.6 mg.

<em>What percent is 0.6 mg of total 11 mg??</em>

Divide 0.6 by 11 and then multiply by 100 to get the answer. So we have:

$\frac{0.6}{11}=0.0545*100=5.45$
