Where is the green sector?

I will assume that the central angle is pi/6 and that the radius is 10 in.

The area of the whole circle is pi*100 units^2.

The green sector has an area of

pi/6

-------- times the area of the entire circle = (1/12) of pi*100 units^2.

2pi

This comes to pi*(100 units^2)

------------------------ = (25/3) pi units^2. That's C.

Answer:

25π/2

Step-by-step explanation:

You can set up a proportion:

area sector /area : circle = A /360 °

In this case : x /100π = 45 /360

x = 1/8 100π = 25π/2

Pregunta completa:

En una empresa trabajan 60 personas. Usan gafas el 16% de los hombres y el 20% de las mujeres. Si el numero total de personas que usan gafas es 11. ¿Cuantos hombres y mujeres hay en la empresa?

Responder:

Hombres = 25

Mujeres = 35

Explicación paso a paso:

Dado lo siguiente:

Número de personas que trabajan en la empresa = 60

Porcentaje de hombres que usan anteojos = 16%

Porcentaje de mujeres que usan anteojos = 20%

Número total de personas que usan anteojos = 11

Suponga, Número de hombres en la empresa = m

Número de mujeres = número total - número de hombres = 60 - m

Por lo tanto,

16% de los hombres = 0,16 m

20% de mujeres = 0,2 (60 - m) = 12 - 0,2 m

Por lo tanto,

0,16 m + 12 - 0,2 m = 11

- 0,04 m = 11 - 12

-0,04 m = - 1

m = 1 / 0.04 = 25

Por tanto, Número de hombres en la empresa = m = 25

Número de mujeres en la empresa = (60 - m) = (60 - 25) = 35 mujeres

Suppose there is a deck where every card has both a single color and a single number. Suppose the colors are Red, Green, and Blu

Elza [17]

Answer:

A. P = 1.7% (rounding to the next tenth)

B. P = 33.3% (rounding to the next tenth)

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of red cards = 20

Number of blue cards = 20

Number of green cards = 20

Total number of cards = 60

2. A. What is the probability that a randomly selected card will be Green 1?

Let's recall that the formula of the probability is:

P = Number of favorable outcomes/Total number of possible outcomes

Replacing with the value we have:

P = 1/60 = 0.017

P = 1.7% (rounding to the next tenth)

B. What is the probability that a randomly selected card will be red?

P = Number of favorable outcomes/Total number of possible outcomes

Replacing with the value we have:

P = 20/60 = 0.333

P = 33.3% (rounding to the next tenth)
