Given:

In an office, there are 75 women and 125 men.

To find:

The ratio of the number of men to the number of women.

Solution:

We have,

Number of men = 125

Number of women = 75

The ratio of the number of men to the number of women is:

\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}

\text{Required Ratio}=\dfrac{125}{75}

\text{Required Ratio}=\dfrac{5}{3}

\text{Required Ratio}=5:3

Therefore, the ratio of the number of men to the number of women is 5:3.

of 320 consumers polled, some purchase blu-ray movies, some only purchase movies on dvd, and some do both. if 300 people polled
Helga [31]

Answer:

20 people only buy dvds.

Step-by-step explanation:

There are two groups in this problem. One group of people that buys dvds and one that buys blu rays. The total amount of people who buy blu rays is 300, but there's an intersection between the groups and the size of this is 280 people who actually buy both. In order to find out how many people only buy DVDs we first need to figure out how many only buy blu-rays. That is:

people who only buy blu rays = people who buy blu rays - people who buys blu rays and dvds

people who only buy blu rays = 300 - 280 = 20

We can now calculate the amount of people who only buy dvds and that is:

people who only buy dvds =total amount of people - ( people who only buy blu rays + people who buy both)

people who only buy dvds = 320 - (20 + 280) = 320 - 300 = 20 people

Please I need help and the calculation of which contract is better.
kramer

Answer:

You should go with the 1st, because it's cheaper.

Step-by-step explanation:

1st plan:

30$ which include 75 mins of free calls and 100 free text messages

25 more mins * 10¢ /min(0.1$/min) = 2.5$

You will pay 32.5$

2nd plan:

(calls)100*0.3$=30$

(text messages)100 * 0.1$=10$

30+10 = 40$

Please answer the question 50 points and brainliest
Olin [163]

The volume of a cone is V=1/3*pi*r^2*h

Since the value of r is 6 and the value of h is 8, we get:

V=1/3*pi*6^2*8

V=1/3*pi*36*8

V=12*pi*8

V=96pi

V=301.5928947

So the exact volume of the cone is 301.5928947 m^3

The approximate value of the volume rounded to the nearest tenth is 301.6 m^3
