A stack of 500 pieces of paper is 1.875 inches tall.

Mathematics

gtnhenbr [62]3 years ago
8 0

If there were 1000 sheets of paper, then the thickness of each sheet would be 1.875 in divided by 1000.

1.875/1000 = 0.001875

Since there are 500 sheets of paper, each one is twice as thick as 0.001875, so each sheet is 0.00375 inches thick. 0.015 is much greater than 0.00375, so it must be incorrect.

Yakvenalex [24]

Answer:

El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.

Step-by-step explanation:

De acuerdo con este problema, tenemos un ángulo y dos lados adyacentes, por tanto, podemos determinar la distancia entre las ciudades A y B, medida en kilómetros, por la Ley del Coseno, definida como sigue:

AB = \sqrt{AC^{2}+BC^{2}-2\cdot AC\cdot BC\cdot \cos C} (1)

Donde:

AC - Distancia entre las ciudades A y C, medida en kilómetros.

BC - Distancia entre las ciudades B y C, medida en kilómetros.

C - Ángulo en la ciudad C, medida en grados sexagesimales.

Si tenemos que AC = 5\,km, BC = 8\,km y C = 36^{\circ}, entonces:

AB = \sqrt{(5\,km)^{2}+(8\,km)^{2}-2\cdot (5\,km)\cdot (8\,km)\cdot \cos 36^{\circ}}

AB \approx 4,927\,km

El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.

A survey find that 61% of people are married. They ask the same group of people and 75% of them have at least one kid. If 48% ar
dalvyx [7]

Answer:

22/25

Step-by-step explanation:

The overlap between the 61% and the 75% is the 48%, which means that 13% of the people are married and have no kids (61-48=13)

The 75% includes the people who have one or more kids, and<em> </em>the people who have one or more kids <em>and</em> are married.

Now all we have to do is 13% + 75% = 88% = 22/25
