Answer:

AC ≈ 16.8 cm ( to 1 dec. place )

Step-by-step explanation:

Using the sine ratio in the right triangle

sin71° = \frac{opposite}{hypotenuse} = \frac{AB}{AC} = \frac{15.9}{AC}

Multiply both sides by AC

AC × sin71° = 15.9 ( divide both sides by sin71° )

AC = \frac{15.9}{sin71} ≈ 16.8 cm

Answer:

16.8 cm

Step-by-step explanation:

Sin (theta)=opposite/HYPOTENUSE

Where theta=71 and opposite=15.9

Putting in the above formula

Sin 71=15.9/AC

AC=15.9/sin71

AC=15.9/0.945

AC=16.8 cm

babymother [125]

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

Thus, 5.45% of RDA of iron is provided by an 8 oz glass of grape juice.
