Answer:

11 c; 12 c; 13 b

Step-by-step explanation:

Question 11

\text{Volume} = \text{4 doses} \times \dfrac{\text{2 T}}{\text{1 dose}}\times \dfrac{\text{15 mL}}{\text{1 T}} = \textbf{120 mL}

Question 12

(a) Add up the total fluid ounces

\begin{array}{rr}\textbf{Liquid} & \textbf{V/oz} \\\text{Juice} & 6 \\\text{Water} & 4 \\\text{Soda} & 8 \\\text{Coffee} & 10 \\\text{Milk} & 6 \\\text{Total fluids} & 34 \\\end{array}

(b) Convert fluid ounces to millilitres

\text{Volume} = \text{34 oz} \times \dfrac{\text{15 mL}}{\text{1 oz }} = \textbf{510 mL}

Question 13

1 L =10 dL

\text{Volume} = \text{80 dL} \times \dfrac{\text{1 L}}{\text{10 dL}} = \textbf{8.0 L}

From a radar station, the angle of elevation of an approaching airplane is 32.5 degree. The horizontal distance between the plan
denis23 [38]

Answer: 42.21 km

Step-by-step explanation:

We can solve this using trigonometry, since we have the following data:

\theta=32.5\° is the the angle of elevation

d=35.6 km is the horizontal distance between the plane and the radar station

x is the hypotenuse of the right triangle formed between the radar station and the airplane

Now, the trigonometric function that will be used is <u>cosine</u>:

cos\theta=\frac{d}{x} because d is the adjacent side of the right triangle

cos(32.5\°)=\frac{35.6 km}{x}

Finding x:

x=\frac{35.6 km}{cos(32.5\°)}

x=42.21 km
