Yes.

For example if we know the lengths of 2 adjacent sides and the measure of the included angle we can find the length of the other side.

That's true; the Law of Cosines works with all triangles. With right triangles it simplifies to the Pythagorean Theorem.

A solid right pyramid has a regular hexagonal base with an area of 7.4 units2. The pyramid has a height of 6 units.

Lelechka [254]

Answer: Second option.

Step-by-step explanation:

You need to use the following formula:

$V=\frac{1}{3}Bh$

Where "B" is the area of its base and "h" is the height.

According to the data given in the exercise, you know that:

$B=7.4 units^2\\\\h=6\ units$

Therefore, knowing this values, you can substitute them into the formula shown before and then evaluate, in order to calculate the volume of thi right pyramid whose base is a regular hexagon.

Then, you get:

$V=\frac{1}{3}(7.4 units^2)(6\ units)\\\\V=14.8\ units^3$

Agustín fabrica artículos de cuero y los vende con un incremento del 8% de su costo. Si en su última campaña utilizó un cuero de

nadezda [96]

Answer:

El aumento del precio de costo único equivalente es un aumento del 20,96% en el precio de costo

Step-by-step explanation:

Los parámetros dados son;

El porcentaje de aumento en el precio de costo que Augustin vende artículos de cuero = 8%

El aumento adicional de Augustin se aplica cuando usó cuero de mayor calidad = 12%

Sea x el precio de costo

Tenemos, el primer precio de venta = 1.08 × x

El precio de venta del cuero de alta calidad = 12% adicional al precio de venta anterior

∴ El precio de venta del cuero de alta calidad = 1,12 × 1,08 × x = 1,2096 × x

Por lo tanto, el precio de venta del cuero de alta calidad = (1.2096 × 100)% de x = 120.96% de x, lo que da;

El aumento del precio de costo único equivalente = (120,96% - 100%) aumento en x = 20,96%

∴ El aumento del precio de costo único equivalente = 20,96% de aumento en el precio de costo.
