The number after rounding off to the nearest tenth will be 9.4

In this question, we have been given that Miguel made up an equation in which three times of square of a particular number equals 265. We have to set up the equation according to this.

Taking the number as 'x'. We get the equation according to the condition :

               => 3x² = 265

By solving this equation we get :

               =>  3x² = 265    =>  x² = 88.3

               => x = 9.39

We get x = 9.39. By rounding off x to the nearest tens, we get x = 9.4

Answer:

131°

Step-by-step explanation:

Sum of all angles of a quadrilateral = 360°

We can find the unknown angle ∠B, by subtracting the sum of the angles ∠A, ∠C, ∠D from 360°.

∠A + ∠B + ∠C + ∠D = 360

105 + ∠B + 34 + 90  = 360

           ∠B +  229      = 360

                     ∠B       = 360 - 229

                           ∠B = 131°

Answer:

The measure of m<GHE is 49°, the correct option is B.

What is a Quadrilateral?

A quadrilateral is a polygon with four sides.

It is of various types,

Trapezoid, which have one pair of parallel sides,

Parallelogram, it has two pairs of parallel sides,

Rhombus, it has all sides equal,

Rectangle, opposite sides are parallel and equal, and,

Square, all sides are equal and opposite sides are parallel, and all angles have measure of 90 degree.

The quadrilateral ABCD is ≅ quadrilateral EFGH

When two figures are congruent then by CPCTC, corresponding parts of congruent figures are congruent.

The measure of the angle

B = m<BCD = 90°

m<BAD = 131°

As the quadrilaterals are congruent,

By CPCTC

∠F = ∠FGH = 90°

m ∠FEH =  131°

The measure of m<GHE has to be determined.

The sum of the measures of all angle so of a quadrilateral is 360 degree.

The ∠F + ∠FGH + ∠FEH + ∠GHE = 360

90 +90+ 131 +∠GHE = 360

∠GHE = 49°

Step-by-step explanation:

Solving a quadratic equation, it is found that the largest possible value of a is of a = 5.

A quadratic equation is modeled by the following rule:

y = ax^2 + bx + c

The solutions of the equations are the values of x for which y = 0.

For this problem, the equation is:

a² - 6a - 9 = b.

b = -9 - a, hence we replace in the equation as follows;

a² - 6a - 9 = -9 - a

a² - 5a = 0.

Traditionally, the solutions are given using Bhaskara's formula, however, since the coefficient c is zero, we can solve the equation by elimination as follows:

a² - 5a = 0.

a(a - 5) = 0.

Then the solutions are:

5 > 0, hence the largest possible value of a is of a = 5.

Answer:

267/5 ( or ) 53.2

Step-by-step explanation:

Note : -

□ means 90°

2x - 42 + 3x + 45 + 90 = 360

2x + 3x + 45 - 42 + 90 = 360

5x + 3 + 90 = 360

5x + 93 = 360

5x = 360 - 93

5x = 267

x = 267/5 ( in fraction )

    ( or )

x = 53.2° ( in decimal )

The solution to the system of equation is x = 6, y = 4, z = 5

The equation is

1.5x + y - z = 8

x + 3y = 18

2y + z = 13

From this we have,

y = 8 - 1.5x + z

x + 3y = 18

2y + z = 13

x + 3(8 - 1.5x + z) = 18

2(8 - 1.5x + z) + z = 13

Apply the Distributive Property

x + 24 - 4.5x + 3z = 18

16 - 3x + 2z + z = 13

Combine like terms

-3.5x + 24 +3z = 18

16 - 3x + 3z = 13

Rearrange variables to the left side of the equation

-3.5x + 3z = 18 - 24

-3x + 3z = 13 - 16

Subtract the two equation

-3.5x + 3z - (-3x + 3z ) = 18-24 - ( 13-16)

-3.5x + 3z + 3x -3z = 18 - 24 - 13 + 16

-3.5x + 3x = 18 - 24 - 13 + 16

x = 6

Substitute the value of x in one of the equation

-3×6 + 3z = 13 - 16

-18 + 3z = -3

3z = 15

z = 5

Now put the value of x and z

y = 8 - 1.5x + z

y = 8 - 1.5×6 + 5

  = 8 -9 + 5

  = 4

Therefore the solution to the system of equation is x= 6, y = 4 and z = 5

Answer:

answer for this question is alternative A (80, 60) & (95,85)

Answer:

(0, 1 )

Step-by-step explanation:

2x + 5y = 5 → (1)

- 3x + 7y = 7 → (2)

to eliminate y multiply (1) by 7 and (2) by - 5 , then add the result

14x + 35y = 35 → (3)

15x - 35y = - 35 → (4)

add (3) and (4) term by term to eliminate y

29x + 0 = 0

29x = 0 ⇒ x = 0

substitute x = 0 into (1) and solve for y

2(0) + 5y = 5y

0 + 5y = 5

5y = 5 ( divide both sides by 5 )

y = 1

solution is (0, 1 )

The interval to find the true average tip is  (14.62,13.78).

Average is a number that is calculated by adding quantities together and dividing the total by the number of quantities.

The Standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range

Given:

We know that the confidence interval = sample mean ± standard deviation substitute the values in it then confidence interval = 14.2  ±2.5/(35)^1/2

confidence interval = 14.2 ± 2.5/5.91

confidence interval = 14.2 ± 0.42

confidence interval = 14.2 + 0.42 ,

confidence interval = 14.2 - 0.42

confidence interval = (14.62,13.78)

So, an interval to estimate the true average tip is  (14.62,13.78).

The measure of ∠EBF is 56°.

Here, we are given that-

m ∠EBC = 3 r + 10 °

and m ∠ABE = 2 r − 20 °

Also we can observe that ∠EBC and ∠ABE are angles on a straight line and hence will be supplementary.

⇒ ∠EBC + ∠ABE = 180

⇒ 3r + 10 + 2r - 20 = 180

5r - 10 = 180

5r = 180 + 10

5r = 190

r = 190/5

r = 38

Thus, ∠ABE = 2(38) - 20

The length of the diagonal across the field is 212.132 feet.

A rectangle whose all sides are equal is called a square.

A square is always a rectangle, parallelogram, and a quadrilateral but its reverse statement may or may not be true.(ie it is not always necessary that a rectangle is a square or a parallelogram is a square).

Given that a square field has an area of 22,500 square feet. Now, the length of the side of the square field can be written as,

Area of the square field = (Length of square field)²

22,500 square feet = (Length of square field)²

Length of square field = √(22,500 sq. feet)

Length of square field = 150 feet

Now, the length of the diagonal of the field can be written as,

(Length of the diagonal)² = 2(Length of the side of square field)²

(Length of the diagonal)² = 2(150²)

(Length of the diagonal)² = 45,000 sq. feet

(Length of the diagonal) = 212.132 feet

Hence, the length of the diagonal across the field is 212.132 feet.

The investigator can test the presence of simple sugars in the sample by using Benedict's solution.

Simple carbs are tested for using Benedict's Test. With free ketone or aldehyde functional groups, reducing sugars (monosaccharides and some disaccharides) are recognized by the Benedict's test.

Benedict's solution turns orange or brick red when heated in the presence of simple carbohydrates. The reducing characteristic of simple carbs is what triggers this response. The Benedict's solution changes color as a result of the reduction of copper (II) ions to copper (I) ions.

The produced red copper(I) oxide precipitates out of solution because it cannot be dissolved in water. This explains how the precipitate was created. The closer the final hue is approaching brick-red and the more precipitate is generated as the reducing sugar concentration rises. Copper oxide, a brick-red solid, can occasionally precipitate out of a solution and gather at the test tube's bottom.

Pattern uses 6233.76 inches² fabric.

Firstly we will convert units in required form. Therefore, converting equivalent of yard² in inches². As per the given information, 1 yard = 3 feet and 1 foot = 12 inches.

As 1 foot = 12 inches, so, 3 feet = 36 inches, which is further equal to 1 yard.

Now, 1 yard² = (36 inches)²

1 yard² = 1296 inches²

Coming back to the problem, we will now calculate inches² from fabric measurement in yard². So, relating the units for conversion.

1 yard² = 1296 inches²

4.81 yard² = 1296 × 4.81

Performing multiplication

Measurement of 4.81 yard² in inches² = 6233.76
