Answers

Answer:

The missing base measure of the enlarged trapezoid is 4cm.

Step-by-step explanation:

Step 1:

2 / 3.25 = x / 6.5

Step 2:

Cross product

2 * 6.5 = 3.25 * x

Step 3:

Simplify

13 = 3.25x

Step 4:

Divide both sides by 3.25

13 / 3.25 = 3.25x / 3.25

4 = x

x = 4

For a given input value a, the function f outputs a value b to satisfy the following equation.
-3a+6b=a+4b
Write a formula for f(a) in terms of a

Answers

Answer:

ok

Step-by-step explanation:

-3a + 6b = a + 4b

we move both values to the same side

6b – 4b = a + 3a

subtracting 6 from 4 gives us 4, and a 1 plus 3 gives us 4

2b = 4a

divide 4 on both sides to solve for a and to get a by itself.

1/2=a

please mark as brainlest.

Hey there!

Let's solve for a.

[tex] \fbox{−3a+6b=a+4b}[/tex]

Step 1: Add -a to both sides.

[tex] \fbox{−3a+6b+−a=a+4b+−a}[/tex]

[tex] \fbox{−4a+6b=4b}[/tex]

Step 2: Add -6b to both sides.

[tex] \fbox{−4a+6b+−6b=4b+−6b}[/tex]

[tex] \fbox{−4a=−2b}[/tex]

Step 3: Divide both sides by -4.

[tex] \fbox{−4a/−4 = −2b/−4}[/tex]

[tex] \fbox{a= 1/2b}[/tex]

Answer:

[tex] \fbox{a= 1/2b}[/tex]

Answer:

This company has information about businesses and complaints that have been filed against them. It would be a good idea to check here before making large purchases.

Answers

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.

What is business reputation?

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.

Circle A has a circumference of 25 centimeters. Circle B's diameter is 3 times as long as circle A’s diameter. What is the circumference of circle B?


- And don’t say 10 because it’s wrong

Answers

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

Answers

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

What is the independent events?

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:

A. The burrito is a chicken burrito.B. The burrito is a carne asada burrito. C. The customer requested black beans. D. The customer requested pinto beans.

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).

A balance scale is perfectly balanced with 2 cans of soda on one side and 1 can of soda and 8 ounces of sand on the other . How much does each can of soda weigh?

Answers

The balance scale is perfectly balanced when it sits perfectly

The weight of each can of soda is 8 ounces

How to determine the weight of the soda can

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
