Answer:

Step-by-step explanation:

Draw a triangle and label the sides a, b and c. Now we must know the rule you can use for drawing any triangle:

A+B> c

A+C>B

B+C>A

Sub you numbers into the rule:

8+10, is it greater that 19?

No, 8+10=18 and 18<19

This is proof that you can not draw a triangle with the side lengths of 8m, 10m and 19m.

This really depends on the fraction; if there are variables in the equation, if they are full numbers,etc. I'd really recommend looking up khan academy on YouTube and that will really help you out!

La densidad de un líquido es de 1.5 gr/cm3 su masa es de 7 libras Determina la cantidad de litros que ocupan dichos líquidos

egoroff_w [7]

Answer:

La cantidad de litros que ocupa dicho líquido es:

2,12 Litros

Step-by-step explanation:

El volumen de un líquido puede obtenerse al tener tanto su densidad como su masa usando la siguiente fórmula:

Densidad = masa / volumen

Al despejar volumen se obtiene:

Volumen = masa / densidad

Por lo cual, si se reemplazara la fórmula quedaría:

Volumen = 7 Lb / 1.5 gr/cm^3

Sin embargo, para operar, las unidades en las que se expresa la masa deben coincidir con las unidades de la densidad, por lo cual vamos a convertir las libras en gramos teniendo en cuenta el siguiente factor de conversión:

1 libra = 453,592 gramos

Entonces:

7 lb = 453,592 gr * 7 = 3175,144 gr

Ahora este valor reemplaza la masa en la fórmula y calculamos:

Volumen del líquido = 3175,144 gr / 1.5 gr/cm^3

Volumen del líquido = 2116,762667 cm^3 (He utilizado todos los decimales para obtener el resultado exacto).

A simple vista ya se tiene el volumen del líquido en cuestión, sin embargo, el ejercicio pide que sea expresado en litros, por lo cual vamos a convertir los centímetros cúbicos en litros teniendo en cuenta el siguiente factor de conversión:

1 litro = 1000 centímetros cúbicos.

Ahora podemos aplicar una regla de tres simple, si:

1000 cm^3 = 1 L
2116,762667 cm^3 = x

Y operamos:

x = (2116,762667 cm^3 * 1 L) / 1000 cm^3
x = 2,116762667 L

O si quieres un valor aproximado:

x = 2,12 Litros.

Entonces, la cantidad de litros teniendo en cuenta la densidad y la masa brindadas es 2,12 litros.

Mrs Dang drove her daughter to school at the average speed of 45 miles per hour. She returned home by the same route at the aver

drek231 [11]

Answer: Time it took her to get to the school is 0.6 hours

The distance of the school from their home is 27 miles

Step-by-step explanation:

Mrs Dang drove her daughter to school at the average speed of 45 miles per hour.

Let x miles = distance from the school to their home.

Distance = speed × time

Time = distance / speed

Time used in going to school will be

x/45

She returned home by the same route. This means that distance back home is also x miles.

She returned at an average speed of 30 miles per hour.

Time used in returning home from school will be x/30

x/45

If the trip took one half hour, then the time spent in going to school and the time spent in returning is 1 1/2 hours = 1.5 hours. Therefore

x/30 + x/45 = 1.5

(15x + 10x) /450 = 1.5

15x + 10x = 450 × 1.5 = 675

25x = 675

x = 675/25 = 27

Time it took her to get to the school will be x/45

= 27/45 = 0.6 hours
