There would be 35 rulers.

In order to solve this, use cross multiplication.

6/10 = 21/x -----> cross multiply

10*21 = 6*x

210 = 6x

35 = x

The cable company is analyzing data from two satellite television providers to determine whether their users spend more time wat
Phoenix [80]

Answer:

59%

Step-by-step explanation:

The information from Satellite Company Y is:

65 people watch live and 94 people watch recorded.

The total number of people from Y is:

65 + 94 = 159

So the probability that a random person from Y watches recorded shows more often is given by the division of the number of people watching more recorded shows (94) over the total number of people (159):

Probability = 94 / 159 = 0.5912 = 59.12%

Rounding to nearest whole percent, we have 59%

What is the volume in cubic centimeters of a right circular cone with radius 2 centimeters and height 9 centimeters?
andreev551 [17]

Answer:

V = 37.7cm^3

Step-by-step explanation:

The formula for the volume of a cone is:

V = \frac{1}{3} \pi r^2h

Given:

- Radius = 2cm

- Height = 9cm

Let's plug these into the equation:

V = \frac{1}{3} \pi (2)^2(9)

Now solve:

V = \frac{1}{3} \pi (4)(9)\\V = \frac{1}{3}\pi 36\\V = \frac{36}{3}  \pi \\V = 12\pi \\V = 37.7cm^3

Therefore, the volume of the cone is 37.7cm^3.
