12 inches in 1 foot 12/18= 1.6 So 1 foot and 6 inches or 1.5 feet

Answer:

B) only Jake is correct

Step-by-step explanation:

Marcy comes to the correct conclusion, but the statement "therefore the measure of each of the angles has to be half of 180°" comes too early and is not supported by the previous logic. Had it been the very last statement in the argument, she would have been correct as well.

Concluimos que la opción correcta es "Solo II".

Una expresión es una sucesión aritmética si y solo si existe entre dos elementos consecutivos cualesquiera de la serie la misma diferencia. La sucesión aritmética es definida por una expresión de la forma:

\(a_{n} = a + b\cdot n\), \(n\in \mathbb{N}\) (1)

Donde \(a,b\) son coeficientes de la sucesión.

Asimismo, una expresión es una sucesión geométrica si y solo si entre dos elementos consecutivos cualesquiera de la serie existe la misma razón. La sucesión geométrica es definida por una expresión de la forma:

\(a_{n} = a\cdot r^{b\cdot n}\), \(n\in \mathbb{N}\) (2)

Donde \(a, b, r\) son coeficientes de la sucesión.

Por último, una expresión es una sucesión monótona creciente si dados dos elementos consecutivos de una serie, el elemento posterior es siempre mayor que el elemento anterior. Matemáticamente, debe satisfacerse la siguiente condición:

\(\frac{a_{n+1}}{a_{n}} > 1, n\in \mathbb{N}\) (3)

Esta claro por inspección directa que la sucesión dada no es aritmética ni geométrica y cabe comprobar si es monótona creciente. Valiéndonos de (3), realizamos las operaciones algebraicas pertinentes:

\(r = \frac{1700 + 4,1\cdot (n+1)^{2}+304,9\cdot (n+1)}{1700 + 4,1\cdot n^{2}+304,9\cdot n}\)

\(r = \frac{1700+4,1\cdot (n^{2}+2\cdot n +1) +304,9\cdot (n+1)}{1700 + 4.1\cdot n^{2}+304,9\cdot n}\)

\(r = \frac{1700+4,1\cdot n^{2}+304,9\cdot n+4,1\dot (2\cdot n +1) +304.9}{1700+4,1\cdot n^{2}+304,9\cdot n}\)

\(r = 1 + \frac{8,2\cdot n +309}{1700 + 4,1\cdot n^{2}+304,9\cdot n}\)

Como puede apreciarse, \(r > 1\). Por tanto, la sucesión es monótona y creciente.

En consecuencia, concluimos que la opción correcta es "Solo II".

Answer:

answer  in picture

Step-by-step explanation:

Let's represent the number with the variable "x". According to the given property, we can write the following equation:

3(x + 4) < 7x

Now, let's solve this inequality to find the range of numbers that satisfy the property.

3x + 12 < 7x

Subtract 3x from both sides:

12 < 4x

Divide both sides by 4 (since the coefficient of x is 4):

3 < x

So, the range of numbers that satisfy the given property is x > 3.

Therefore, any number greater than 3 will satisfy the condition. For example, 4, 5, 6, 7, 8, etc.Step-by-step explanation:

The number of cups for small pitchers = 2

The number of cups for large pitchers = 4.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Two small pitchers and three large pitchers can hold a total of 16 cups of water.

And, The large pitcher holds 2 more cups of water than the small pitcher.

Now,

Let number of cups for small pitchers = x

And, The number of cups for large pitchers = y

Here, Two small pitchers and three large pitchers can hold a total of 16 cups of water.

So, We can formulate;

⇒ 2x + 3y = 16  .. (i)

And, The large pitcher holds 2 more cups of water than the small pitcher.

So, We get;

⇒ y = 2 + x  .. (ii)

Substitute the value of y from (ii) in (i), we get;

⇒ 2x + 3 (2 + x) = 16

Solve for x as;

⇒ 2x + 6 + 3x = 16

⇒ 5x = 16 - 6

⇒ 5x = 10

⇒ x = 2

And, From (ii);

⇒ y = 2 + x

⇒ y = 2 + 2

⇒ y = 4

Thus, The number of cups for small pitchers is 2

The number of cups for large pitchers is 4.

Answer:

Answer : 21%

Step-by-step explanation:

To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.

There are 12 7th-graders and 8 8th-graders. So the total number of ways she can pick is:

12×8=96

To get two boys picked, there are 5 boys in the 7th-grade class and 4 in the 8th-grade class, so there are:

5×4=20 ways

Which gives us the probability of:

2096=524≅21%

The length of line having mid point B ⇒  7x - 2.

Given that,

B is the mid point of AC

And also given that

length of segment AB = 2x+5

And length of segment BC = 5x - 7

A straight path established by linking a group of points in a plane is known as a line. It is a one-dimensional form with only a length and no width or height. A line can extend indefinitely in both ends in opposite directions. To indicate a line, we can use upper case characters.

Now since B is the mid point of AC,

So, The line AC is sum of the line segment AB and line segment BC.

Therefore,

AC = AB+BC

     = (2x+5)+(5x - 7)

     = 7x - 2

Hence,

The length of AC is 7x - 2

Step-by-step explanation:

The length of BD is 22.

In the given scenario, let's consider the following information.

AD = 8

AE = 6

EC is 12 more than BD.

To find the length of BD, we can utilize the Intercepted Arcs Theorem, which states that when two secants intersect outside a circle, the measure of an intercepted arc formed by those secants is equal to half the difference of the measures of the intercepted angles.

From the given information, we know that AD = 8 and AE = 6.

Since these are the lengths of the secants, we can use them to calculate the intercepted arcs.

First, let's find the intercepted arc corresponding to AD:

Intercepted Arc ADB = 2 \(\times\) AD = 2 \(\times\) 8 = 16

Similarly, we can find the intercepted arc corresponding to AE:

Intercepted Arc AEC = 2 \(\times\) AE = 2 \(\times\) 6 = 12

Now, we know that EC is 12 more than BD.

Let's assume the length of BD as x.

BD + 12 = EC

Now, let's consider the intercepted arcs theorem:

Intercepted Arc ADB - Intercepted Arc AEC = Intercepted Angle B - Intercepted Angle C

16 - 12 = Angle B - Angle C

4 = Angle B - Angle C.

Since Angle B and Angle C are vertical angles, they are congruent:

Angle B = Angle C.

Therefore, we can say:

4 = Angle B - Angle B

4 = 0

However, we have reached an inconsistency here.

The equation does not hold true, indicating that the given information is not consistent or there may be an error in the problem statement.

As a result, we cannot determine the length of BD based on the given information.

Answer:

Step-by-step explanation:

This will form triangle VWX. So we have values for ∠VWX and ∠XVW but we don't have value for ∠WXV.

Since ∠WXV and ∠WXY are supplementary angles

=> ∠WXV + ∠WXY = 180

=> ∠WXV = 180 - ∠WXY

So the angles of triangle VXY

∠VWX + ∠XVW + ∠WXV = 180

(x + 14) + (x + 9) + (180 - (5x - 10)) = 180

x + x - 5x + 14 + 9 + 180 + 10 = 180

-3x + 213 = 180

-3x = - 33

Converse: If it is sunny, then it is 80° Fahrenheit. (Invalid)

In cases 1 and 2, the original statements and their converses are valid because the relationship between "sunny" and "80° Fahrenheit" holds in both directions. However, in cases 3 and 4, the converses are invalid because there are counterexamples where the second part of the statement (either "not 80° Fahrenheit" or "cloudy") does not necessarily imply the first part ("not sunny" or "80° Fahrenheit").

Step-by-step explanation:

Half of 40 is 20 and luckily they already gave us how much she would earn if she worked 20 hours.

So all we have to do is multiply the amount of money she earned when she worked 20 hours by 2 to see how much she earned when she worked 40 hours.

20 hours:165 dollars or 20:165

20 x 2= 40 and 165x2=330

So if Monique worked 40 hours she would earn $330.

Step-by-step explanation:

Answer:

  5

Step-by-step explanation:

The limit of f(x) at x=-1 is 5 when approached from the left or right. Since those limits are the same, the limit exists and is ...

  \(\boxed{\lim\limits_{x\to-1}f(x)=5}\)

When the y-value starts to decrease and the x-value remains constant over time, Y decreases and X increases to a consistent slope.

A consistent slope represents a constant rate of change between two variables, typically represented by the ratio of the change in y to the change in x.

When the y-value starts to decrease and the x-value remains the same over time, the consistent slope represents a negative correlation between y and x.

This means that as the value of y decreases, the value of x remains the same or may increase, depending on the context of the problem.

Therefore, the answer is option B: Y decreases and X increases.

h(x) = 36 - 4.9(1.3)^2

h(1.3) = 36 - 27.719
