Me ayudan con el problema dice Arturo compro 6 quesos de 1/4 de Kg cada uno Cuantos Kg de queso tiene?

stepladder [879]

Answer:

1 1/2 kg de queso

Step-by-step explanation:

De la pregunta anterior, sabemos que:

1 queso = 1/4 kg

6 quesos = x kg

Multiplicar cruzada

1 queso × x kg = 6 quesos × 1/4 kg

x kg = 6 quesos × 1/4 kg / 1 queso

x kg = 3/2 kg

x kg = 1 1/2 kg de queso

Step-by-step explanation:

<h3> $\sec \alpha \sqrt{1 - \sin ^{2} \alpha } = 1$ </h3>

Prove the LHS

Using trigonometric identities

That's

<h3> $\cos ^{2} \alpha = 1 - \sin^{2} \alpha$ </h3>

<u>Rewrite the expression</u>

We have

<h3> $\sec \alpha \sqrt{ \cos^{2} \alpha }$ </h3>

<h3> $\sqrt{ { \cos }^{2} \alpha } = \cos \alpha$ </h3>

So we have

<h3> $\sec \alpha \times \cos \alpha$ </h3>

Using trigonometric identities

<h3> $\sec \alpha = \frac{1}{ \cos \alpha }$ </h3>

<u>Rewrite the expression</u>

That's

<h3> $\frac{1}{\cos \alpha } \times \cos \alpha$ </h3>

Reduce the expression with cos a

We have the final answer as

As proven

How do you solve <br> 10 squared + 13 squared = c squared<br> (Pythagorean theorem)

alina1380 [7]

$10^2 + 13^2 =c^2\\\\100 + 169=c^2\\\\269 = c^2\\\\\boxed{\bf{c=\sqrt{269}\approx 16.4}}$
