Find the following arc measures.

Answers

Answer:

Arc KL [tex]=23[/tex]

Arc OM [tex]=113[/tex]

Step-by-step explanation:

We know that Angle NPM is equal to 90 degrees.

Therefore, Angle KPM is also equal to 90 degrees.

We are told that Arc LM is equal to 67.

Thus, the measure for Arc KL is equal to [tex]90-67=23[/tex]

We also know that Angle OPN is equal to Angle KPL.

Therefore, the measure of Arc ON[tex]=23[/tex]

Using that information, we know that Arc OM is equal to [tex]90+23=113[/tex]

.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)

Answers

Answer:

45 g de oxido de hierro (III) liberarán 18.9 L de CO₂

Step-by-step explanation:

La reaccion quimica es la siguiente:

Fe₂O₃ (s) + 3CO (g)  →  2Fe (s) + 3CO₂ (g)

1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.

Pasamos la masa de F₂O₃ a moles:

159.6 g . 1 mol /159.7g = 1 mol de oxido

Entonces, aplicamos la regla de tres:

1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.

Ahora calculamos los nuevos moles:

45g . 1 mol /159.7 g = 0.282 moles

Aplicamos la regla de tres:

Si un mol de oxido produce 3 moles de CO₂

0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂

Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:

Si 3 moles de CO₂ ocupan 67.2 litros

0.845 moles ocuparan (0.845  . 67.2/  3 ) =  18.9 litros

Ross and Ronnie are late for their favorite show . Ross walks around a rectangular park with dimensions of 150 ft by 215 ft. Ronnie decides to cut across the park in a diagonal path. Who walks the shortest distance and by how much? *

Answers

Answer:

Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft

Step-by-step explanation:

The image attached represent the rectangular park. In this case, the dimensions are;

AB = CD = 215 ft

AC = BD = 150 ft

Total distance walked by Ross = AB + BD = 215 + 150 = 365 ft

Distance walked by Ronnie = AD

∠ABD = right angle triangle, using pythagoras rules;

AD² = AB² + BD²

AD² = 215² + 150²

AD² = 68725

AD = √68725

AD = 262.15 ft

Distance walked by Ronnie = 262.15 ft

Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft

Answer:

a=44, b= 58

Step-by-step explanation:

You look at the first triangle that gives you the two angles, and with the rule that every triangle's angles inside it need to add up to 180 degrees, you can determine that the missing angle is 46 degrees, which translates over to the other triangle, meaning that a would be 44 degrees.

The other triangle has two identical angles, being 61 degrees, which helps translate to the smaller triangle, again allowing you to infer that b is 58 degrees
