Calcular la magnitud de la velocidad angular y el período de
una rueda que gira con una frecuencia de 1200 rpm.​

Answers

Answer:

The magnitude of the angular velocity is 125.66 rad / s and the period is 0.05 seconds.

Step-by-step explanation:

The computation of the magnitude and the period is given below:

First we determine the angular velocity that transforming the revolutions per minute,  

So,

ω = (1200 rev / min) ×  (2π rad / rev) × (1 min / 60s)

ω = 125.66 rad / s

Now, the period is  

ω = 2π ÷ T

T = 2π ÷ (125.66 rad / s)

T = 0.05 s

Hence,  the angular velocity has a value of 125.66 rad / s and the period is 0.05 seconds.

240 dollars

In this problem, we need to know how many dollars can he save using the loyalty card.

Since we know that Melvin pays 1,679 dollars per liter and 1,439 dollars per liter using the loyalty card.

To solve this problem, we need to subtract 1,439 from 1,679. We get:

1,679 – 1,439 = 240

We get the final answer as: $240 or 240 dollars.

Cecily’s teacher held a raffle. To win the raffle, a student has to pick a paper scroll with an integer written on it. The chart shows the scrolls picked by Cecily and her friends.

Name

Paper Scroll

Cecily

A scroll labeled 6.7.

Marty

A scroll labeled negative 37.

Jon

A scroll labeled StartFraction 7 Over 9 EndFraction

Fiona

A scroll labeled 3 and one-third.

Who picked the winning scroll?

Cecily picked the winning scroll.

Marty picked the winning scroll.

Jon picked the winning scroll.

Fiona picked the winning scroll.

Answer:

Marty picked the winning scroll.

Step-by-step explanation:

Based on the rule given in other to win, the winning scroll is that which has integer value written on it.

An integer simply means a number devoid of fraction. Hence, it could be a positive or negative while number.

Given that the students pick below :

Cecily = 6.7 (not an integer)

Marty = - 37 (integer)

Jon = 7/9 (not an integer)

The only scroll which meets the condition of being an integer is Marty's scroll ; Hence, she picked the winning scroll.

Una fabrica produce caravanas las envasa en bolsitas de un par cada dos bolsitas usa una cajita azul cada do cajitas azules usa una naranja cada dos cajas naranjas usa una verde si fabrica 500 caravanas cuantas bolsitas cuantas cajitas azuñes cuantas cajas naranjas y cuantas cajas verdes usa

Answers

Answer:

Se utilizan 31 cajas verdes y 62 cajas naranjas, 125 cajas azules y 250 bolsas

Step-by-step explanation:

La pregunta es un problema verbal

Los parámetros dados son;

El número de caravanas por bolsa = 2 caravanas

El número de bolsas en una caja azul = 2 bolsas

El número de cajas azules en una caja naranja = 2 cajas azules

El número de cajas naranjas en una caja verde = 2 cajas naranjas

Por lo tanto;

El número de caravanas en una caja azul = 2 bolsas = 2 pares = 4 caravanas

El número de caravanas en una caja naranja = 2 × 4 caravanas = 8 caravanas

El número de caravanas en una caja verde = 2 × 8 caravanas = 16 caravanas

Por tanto, si la fábrica fabrica 500 caravanas, tenemos;

El número de casillas verdes utilizadas = 500/16 = 31,25 = 31 casillas verdes

El número de cajas naranjas utilizadas = 500/8 = 62 cajas naranjas

El número de cajas azules utilizadas = 500/4 = 125 cajas azules

El número de bolsas utilizadas = 500/2 = 250 bolsas
