two numbers are in a ratio 2:3 and their sum is 35.find the numbers​

Answer:

Using the quadratic formula:

x = [-4 +- sqr root (16 - 4 * 1 * -1)] / 2 *1

x = [-4 +- sqr root (20)] / 2

x1  = [-4 + sqr root (20)] / 2

x2 = [-4 - sqr root (20)] / 2

x1 = 0.23607

x2 = -4.2361

Step-by-step explanation:

Answer:

x = - 2 ± [tex]\sqrt{5}[/tex]

Step-by-step explanation:

Given

g(x) = x² + 4x - 1

To solve for x let g(x) = 0, that is

x² + 4x - 1 = 0 ( add 1 to both sides )

x² + 4x = 1

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 1 + 4

(x + 2)² = 5 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{5}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{5}[/tex]

Thus solutions in exact form are

x = - 2 - [tex]\sqrt{5}[/tex] , x = - 2 + [tex]\sqrt{5}[/tex]

Answer:

x = 10/3

Step-by-step explanation:

3(2x-4) = 8

3*2x + 3*-4 = 8

6x - 12 = 8

6x = 8 + 12

6x = 20

x = 20/6

x = 10/3

Check:

3((2*10/3) - 4) = 8

3(20/3 - 4) = 8

Answer: 100/400

Step-by-step explanation:

The maximum power is 4A.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

The given function

P(x) = - 15x (x-8)

P(x) = - 15x² + 120x

The standard form of a quadratic function is:

y = ax² + bx + c

For which x is the maximum of the parabola

x = - b/2a

So, a = -15 and b = 120.

Then, x = - 120/(2 · (-15))

         x  = - 120/ (-30)

         x = 4A

Answer:

The answer would be D. 12, 15, and 25.

Step-by-step explanation:

The first two sides, sum must be larger than the third side.

so 12+15=27 which is larger than 25

The correct answer for  the side lengths of a triangle is D. 12, 15, 25.

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a traingle has to be greater than the length of the third side.

If a,b,c are the sides of the triangle then,

a + b > c

Now in the given question let us suppose a,b,c be the length of the sides

A. 2, 3, 6

Here, a = 2, b= 3 and c = 6

Applying sides of a triangle rule,

a + b > c

⇒2 + 3=  5 which is less than 6

Here, a + b <c

Therefore , these are not the lengths of triangle.

B. 9, 10, 19

Here, a = 9, b= 10 and c = 19

Applying sides of a triangle rule,

a + b > c

⇒9 + 9=  18 which is less than 19

Here, a + b <c

Therefore , these are not the lengths of triangle.

C. 5, 8, 15

Here, a = 5, b= 8 and c = 15

Applying sides of a triangle rule,

a + b > c

⇒5 + 8 =  12 which is less than 15

Here, a + b <c

Therefore , these are not the lengths of triangle.

D. 12, 15, 25

Here, a = 12, b= 15 and c = 25

Applying sides of a triangle rule,

a + b > c

⇒12 + 15 = 27 which is greater than 25

Here, a + b > c

Therefore , these are the lengths of triangle.

Hence,The correct answer for  the side lengths of a triangle is D. 12, 15, 25.

Answer:

200 : 1

Step-by-step explanation:

Given that,

The diameter of the Sun is 1.4 x 10⁶ km and the diameter of the planet mars is 7000 km.

We need to find the ratio of the diameter of the Sun to the diameter of Mars. Let the ratio is R. So,

[tex]R=\dfrac{\text{diameter of the Sun}}{\text{diameter of Mars}}\\\\R=\dfrac{1.4\times 10^6\ km}{7000\ km}\\\\R=\dfrac{200}{1}[/tex]

Hence, the ratio is 200:1.

The solution is: the value of x, and the angles m∠SQT and  m∠RQS are:

x = 23, m∠RQS = 72°, m∠SQT = 83°.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

Here, we have,

Since we are not told what to look for, we can as well look for the value of x, m∠SQT and  m∠RQS

Given

m∠RQS=(4x-20)°

m∠SQT=(3x+14)°

m∠RQT=155°

The addition postulate is true

m∠RQT= m∠RQS + m∠SQT

Substitute the given parameters into the formula

155 = 4x-20+3x+14

155 = 7x-6

7x = 155+6

7x = 161

x = 161/7

x = 23

Solve for m∠RQS

m∠RQS = 4x-20

m∠RQS = 4(23)-20

m∠RQS = 92-20

m∠RQS = 72°

Solve for m∠SQT

m∠SQT = 3x+14

m∠SQT = 3(23)+14

m∠SQT = 69+14

m∠SQT = 83°

Hence, The solution is: the value of x, and the angles m∠SQT and  m∠RQS are: x = 23, m∠RQS = 72°, m∠SQT = 83°.

Answer: X= 6

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

First, multiply 8 to both sides:

(x/8)8 = (3/4)8

x = (3 * 8)/4

First, divide 8 with 4:

x = 3 * (8/4) = 3 * 2

Finally, simplify by multiplying:

x = 3 * 2

x = 6

x = 6 is your answer.

Complete question :

A statistics professor wants to know the average GPA of the students enrolled in their class. They look up information on Canvas about the students enrolled in the class and compute the average GPA as 3.29

a. State whether the following statement is true or false. The population is all students enrolled in the accounting class.

b. Does the value 3.29 represent the population parameter or the sample statistic?

Answer:

True ; population parameter

Step-by-step explanation: The population comprises of all sets or participants relating to a study or experiment. For example, a population of male adults in the United States refers to the entire pool of adult population in the country. Hence, in the scenario above, the population refers to the entire student in the accounting class since the accounting class represents the entire pool of students.

B.) population parameter

Statistical estimates derived from a population is called the a parameter, since 3.29 represent the average score of the entire class.

Same statistic represents estimates derived from a sample (subset of the entire population).
