Answer:

The discount would be 33.334%

Step-by-step explanation:

For solving the exercise you must take into account that the 3 products correspond to the 100%. If we pay just 2 for 3, we must find the proportion of 2 respect to the total. We use rule of three.

3 -----> 100%

2 -----> x

$x=\frac{2\cdot 100\%}{3}$

$x=66.666\%$

Now, 2 products corresponds to the 66.666%. If we pay 2 and the store give us 3, it means that the store are giving one for free. We are paying the 66.666% of the total of the price. So, the rest, it means 100%-66.666% =33.334% is the discount.

The discount refers to the product we didn't pay for, it means 1 product.

The discount would be 33.334%

Two unidentified flying discs are detected by a receiver. The angle of elevation from the receiver to each disc is 39.48 degree.

Answer:

The answer is "298.83 m"

Step-by-step explanation:

Its gap from its transmitter from each disc comprises of 2 triangles. Its horizontal segment via disc to vertical, and longitudinal segment. Disk height, h, is parallel to a horizontal disc Wink including its line across recipient to disc or horizontal 39. 48^{\circ}

$\to 39. 48^{\circ} = \frac{h_1}{826 \ m}\\\\ \to 826\ m (\ sin 39. 48^{\circ} ) = h_1\\\\ \to 525.18 = h_1\\\\$

if:

$\to \sin 39. 48^{\circ} = \frac{h_2}{1.296 \ km}\\\\ \to \sin 39. 48^{\circ} (1296 \ m) = h_2\\\\ \to 824.01 = h_2\\\\\to h_2 - h_1 = 824.01 - 525.18\\\\$
