La casa de Mauricio está construida en un terreno de forma rectangular, el cual mide el doble de largo que de ancho. Mauricio asegura que el área del terreno es de 242 metros cuadrados. ¿cuál es la expresión algebraica correspondiente al área del terreno?

Answers

Answer:

x^2 = 121

Step-by-step explanation:

Sea el ancho del terreno x metros

Dado que la longitud es el doble del ancho, entonces la longitud será 2 * x = 2x

Matemáticamente, el área de un rectángulo es;

Anchura longitud Por lo tanto, tenemos

x * 2x = 242 metros cuadrados

Así; 2x ^ 2 = 242

x ^ 2 = 242/2

what is the rate of change of y with respect to x for this function​

Answers

Answer:I got -0.2

Step-by-step explanation:

The rate of change of y with respect to x for this function​ should be considered to be the -0.2.

Calculation of the rate of change:

Since

x = -3

y = 3.6

[tex]x_1[/tex] = 5

[tex]y_1[/tex] = 2

So here the rate of change be

[tex]= (y_1 - y) \div (x_1 - x)\\\\[/tex]

= (2-3.6) ÷ (5 + 3)

= -1.6 ÷ 8

= -0.2

Hence, The rate of change of y with respect to x for this function​ should be considered to be the -0.2.

(-2,0) is a solution of the equation 2x - 3y = 6
Is that true or false

Answers

Answer: False

Step-by-step explanation:

To see if (-2,0) is a solution to the given equation, we can plug in the point and solve. If we get the same answer, then it is a solution.

2(-2)-3(0)=6            [multiply]

-4-0=6                     [subtract]

-4≠6

Now, the doesn't equal sign tells us that -4 is not equal to 6. This means the given point is not a solution to the equation, making it false.

Robin is going on vacation with her dogs. The function w(b) = 4b represents the number of

O Each bag of dog food can feed 4 dogs.
O Each bag of dog food costs $4.
Each bag of dog food lasts 4 weeks.
Robin's vacation lasts 4 weeks.

Answers

Answer:

TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT

function is a relationship between inputs where each input is related to exactly one output.

4 in the function w(b) = 4b represents that each bag of dog food lasts 4 weeks.

Option C is the correct answer.

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the function are 3 and 5

The inputs of the function are 1 and 2.

We have,

w(b) = 4b

w = number of weeks.

b = number of bags.

We see that,

when b = 1, w = 4

when b = 2, w = 8

when b = 3, w = 12

This means that,

1 bag of dog food will last for 1 week.

2 bags of dog food will last for 8 weeks.

3 bags of dog food will last for 12 weeks.

4 bags of dog food will last for 16 weeks.

Thus,

4 in the function w(b) = 4b represents that each bag of dog food lasts 4 weeks.

Option C is the correct answer.

Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute. A If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?

Answers

Answer:

The answer is below

Step-by-step explanation:

Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute.

a) If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?

b)  How long did it take Max to complete 4 laps backstroke?  

c) It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke. Write the equation that describes this fact.

d)  What is the length of the swimming pool?

Solution:

a) Speed is the ratio of distance to time, it is given as:

speed = distance/time

1 lap = d meters, hence:

4 laps = 4d meters

Max swims the breaststroke at 50 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_1[/tex] minutes hence:

50 = 4d/[tex]t_1[/tex]

[tex]t_1\\[/tex] = 4d/50

[tex]t_1[/tex] = 2d/25 minutes

b) 1 lap = d meters, hence:

4 laps = 4d meters

Max swims the backstroke at 25 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_2[/tex] minutes hence:

25 = 4d/[tex]t_2[/tex]

[tex]t_2[/tex] = 4d/25 minutes

c) Since It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke

[tex]t_2=t_1+2[/tex]

c)

[tex]t_2=t_1+2[/tex]

[tex]\frac{4d}{25}= \frac{2d}{25}+2\\\\multiply\ through\ by\ 25:\\\\4d = 2d +50\\\\4d-2d=50\\\\2d=50\\\\d=25\ meters[/tex]

triangle ABC is shown in the diagram. The links of the sides are in terms of the variable n, where n >4. complete the inquality

Answers

9514 1404 393

Answer:

  m∠B < m∠A < m∠C

Step-by-step explanation:

We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.

For n = 4, the side lengths are ...

  a = 2(4) = 8

  b = (4) +3 = 7

  c = 3(4) -2 = 10

The longest side is opposite the largest angle, so the ordering of angles is ...

  m∠B < m∠A < m∠C

_____

The triangle inequality requires all of these inequalities be true:

a+b > c   ⇒   3n+3 > 3n-2 . . . always trueb+c > a   ⇒   4n+1 > 2n   ⇒   n > -1/2c+a > b   ⇒   5n-2 > n+3   ⇒   n > 5/4

That will be the case for n > 5/4. The attached graph shows the sides and angles keep the same order for n > 3.

You plug in the same x value for each and see the answer. So 2(5)*10^4= 100000. And for the other we do 4(5)*10^2 which is 200. Since is says that 2x10^4 is 50 times as great as 4x10^2, we know that a is right because 200 * 50 = 100000.

Angel lives 3 3 4 blocks to the east of school. Tyrone lives 7 1 4 blocks to the west of Angel. Nadeem lives 8 blocks to the east of Tyrone. Which student lives closest to school? Show your work, state which student lives closest to school and explain how you know

Answers

Answer:

3 1/2

Step-by-step explanation:

Given that:

Angel lives 3 3/4 blocks to the east of school

Tyrone lives 7 1/4 blocks to the west of Tyrone

Nadeem lives 8 blocks to the east of Tyrone.

Determining each of their homes in terms of distance from school :

Angel = 3 3/4 blocks from school

Tyrone = 7 1/4 blocks to the west of angel

Hence, distance from school will be :

7 1/4 - 3 3/4 = 3 1/2 blocks to the west of school

Nadeem = 8 blocks to the east of Tyrone :

Distance from school will be:

8 - 3 1/2 = 4 1/2 to the east of school.

Hence, 3 1/2 to the west of school is the closet distance of the three.

Hence, Tyrone lives closest to school

Farmer johns wants to make a circular Corral for his horses. If the diameter is to be 500 m, how many meters of fencing is needed? Round to the nearest whole number? Use 3.14 for pie.

Answers

Answer:

1570 meters

Step-by-step explanation:

The circumference of a circle is 2πr, so we would start by finding the radius. The radius is half of the diameter, so r=1/2(500)=250. We would then plug in numbers to the equation getting:

2(250)(3.14)

=500(3.14)
