Answer:  74.98cm

Step-by-step explanation:

Step 1: Find out radius of Circle A. [We use circumference of circle A to find its radius].

Circumference of circle A = 2πr; where r is radius.  

To better viewing we change sides, we get:

                                     2πr = Circumference of circle A

                                     2πr = 25

                                         r = [tex]\frac{25}{2\pi }[/tex]

                                         r = [tex]\frac{25}{3.14}[/tex]

                                         r ≈ 3.98

Step 2: Calculate the diameter of circle A.

diameter of circle A = 2r = 2(3.98) = 7.96

Step 3: Finding diameter of circle B.

diameter of circle B = 3(diameter of circle A) = 3(7.96) = 23.88

Step 4: Converted diameter of circle B to r.

diameter of circle B = 2r

                      23.88 = 2r

divided 2 from both sides, we get:

                        11.94 = r

Step 5: Substitute radius of circle B into the circumference formula, where C = 2πr.

C = 2πr

C = 2(3.14)(11.94)

C ≈ 74.98

It is essential to analyze a company's reputation before making large purchases, that is, researching information about the company and complaints that have been filed against them, to verify the company's reliability.

It corresponds to an organization's public perception of its operations, products and services and corporate governance. A company's reputation can be positive or negative, and it is changeable according to its actions.

Therefore, it is essential that a customer seeks to consume from companies that have a good reputation in relation to the entire process of selling products and services, as well as their socio-environmental responsibility.

And companies must implement strategies that generate value for the consumer through positive practices that promote social and environmental development, in addition to quality and good service.

Answer:

4.8 or about 5 miles

Step-by-step explanation:

In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in one mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

Step-by-step explanation:

The two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).

Independent events are those events whose occurrences do not depend on the other events.

A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested.

Consider the following events:

The probability of event A is,

[tex]P(A)=\dfrac{83}{240}[/tex]

The probability of event B is,

[tex]P(B)=\dfrac{80}{240}=\dfrac{1}{3}[/tex]

The probability of event C is,

[tex]P(C)=\dfrac{45}{240}=\dfrac{3}{16}[/tex]

The probability of event D is,

[tex]P(A)=\dfrac{72}{240}=\dfrac{3}{10}[/tex]

If the probability of an event is calculated given that the other is happened, only the probability of event B and D we get such that,

[tex]P(B\cap D)=P(B).P(D)\\\dfrac{24}{240}=\dfrac{1}{3}\times \dfrac{3}{10}\\\dfrac{1}{10}=\dfrac{1}{10}[/tex]

Thus, the two events which are independent are the carne-asada burrito (B) and the customer requested pinto beans (D).

This value is exact

==================================================

Explanation:

Add up everyone in the "has a pet" column to get 22+78 = 100. So we have 100 people who have a pet.

Add up every value in the "male" row to get 22+66 = 88. So there are 88 males

It's tempting to say that 100+88 = 188 people either have a pet or are male, but we're double counting the 22 males who have a pet (top left corner). So we must subtract that value off to get 188-22 = 166

Another way you could look at it is to add up every value that is either in the "has pet" column or is in the "male" row, giving us: 22+78+66 = 166

So there are 166 people who either have a pet, are male, or both.

This is out of 22+66+78+34 = 200 people total

Divide the two values to get 166/200 = 0.83 = 83%

[tex]Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height[/tex]

Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.

[tex]Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24[/tex]

Cancel out the "2" by dividing it by 18.

[tex]Area \ of \ triangle = 9 \times24[/tex]

The balance scale is perfectly balanced when it sits perfectly

The weight of each can of soda is 8 ounces

Represent the weight of the can with x.

On the first side, where there are 2 cans of soda.

The weight is 2x

On the other side, where there is 1 can of soda and 8 ounces of sand

The weight is x + 8

Since the balance scale is perfectly balanced, then we have the following equation

2x = x + 8

Subtract x from both sides

x = 8

Hence, the weight of each can of soda is 8 ounces
