Answer:

x = 9

Step-by-step explanation:

since the terms are in AP then there is a common difference between consecutive terms, that is

a₂ - a₁ = a₃ - a₂ ( substitute values )

x - 7 = 11 - x ( add x to both sides )

2x - 7 = 11 ( add 7 to both sides )

2x = 18 ( divide both sides by 2 )

x = 9

Answer:

9

Step-by-step explanation:

The nth term of an AP has the formular

a+ ( n - 1 ) d

a = first term

n = number of terms

d = common difference

common difference d = T2 - T1 0r T3 - T2

d = x - 7 or 11 - x

Therefore,

3rd term

a + (3 - 1)d

a + 2d

Hence,

7 +2d = 11

substitute the value of d above

7 + 2 (x -7) = 11

7 + 2x - 14 = 11

2x = 11 +14 -7

2x = 18

dividing bothsides by 2

x = 18/2

x = 9

Answer:

8, 12, 16, 20, 24, 28, 32, 36

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

a₁ is the first term and d the common difference

given a₁ = 4 and a₁₀= 40 , then

4 + 9d = 40 ( subtract 4 from both sides )

9d = 36 ( divide both sides by 9 )

d = 4

add d to each term to obtain the next term

4 + 4 = 8

8 + 4 = 12

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

24 + 4 = 28

28 + 4 = 32

32 + 4 = 36

the 8 terms between 4 and 40 are

8, 12, 16, 20, 24, 28, 32, 36

The color that has the greatest difference between the theoretical and experimental probability is yellow.

Theoretical probability of each color = number of color in each section / total number of sections

1/5 = 0.2

Experimental probability is based on the result of an experiment that has been carried out multiples times

Experimental probability

Experimental probability of choosing orange = 118 / 625 = 0.19

Difference = 0.2 - 0.19 = 0.01

Experimental probability of choosing purple = 137 / 625 = 0.22

Difference 0.22 - 0.2 = 0.02

Experimental probability of choosing brown = 122 / 625 = 0.20

0.2 - 0.2 = 0

Experimental probability of choosing yellow = 106 / 625 = 0.17

0.20 - 0.1696 = 0.0304

Experimental probability of choosing green = 142 / 625 = 0.23

The total angle of each diamond is 360 degrees. The opposite angles of the diamond are congruent.

Congruency: In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

The two adjacent angles are 2x + 20 degrees and 50 degrees.

Opposite angles measure 2x + 20 and 50 degrees.

The sum of the angles of each rectangle is 360

2x + 20 + 50 + 2x + 20 + 50 = 360

Add the line terms and subtract

4x + 140 = 360

Subtracting140 on both sides:

4x = 2

Divide both sides by 4

x = 55

55 is the correct answer.

Answer:

Option A

Step-by-step explanation:

Answer:

65 degrees

Step-by-step explanation:

Relative to angle A, you are given the measure of the opposite side and the hypotenuse of the right triangle. When it comes to right triangles, we know through our trig identities that the sin of an angle is equivalent to the length of the opposite side over the hypotenuse. Therefore, we can use trig to solve this problem:

[tex]sinA=\frac{a}{c}[/tex]

If we sub in the values of a and c which are given to us, we get the following:

[tex]sinA=\frac{10}{11}[/tex]

To solve for A, we can take arcsin(10/11) because arcsin is inverse:

[tex]A=arcsin(\frac{10}{11} )[/tex]

Using a calculator, we get that A is approximately 65 degrees

Option D is correct.

Figures are missing in the question.

The images below shows the missing figures of question.

For congruent figures, we need the same shape, same area, and inverse direction.

Congruent figures have congruency. That seems simple enough, but congruent figures need not be turned the same way or face the same direction to be congruent.

In the case of geometric figures, line segments with the same length are congruent and angle with the same measure are congruent.

In elementary geometry the word congruent is often used as follows. The word equal is often used in place of congruent for these objects.

In this sense, two plane figures are congruent implies that their corresponding characteristics are "congruent" or "equal" including not just their corresponding sides and angles, but also their corresponding diagonals, perimeters, and areas.

The figure in option D satisfies all these conditions. Hence, Option D is correct.

Answer:

3.5kg

Step-by-step explanation:

Let original weight  of grapes in box be X and weight of grapes in basket be Y.

From the first sentence
X = 2Y  (weight in box = 2 times weight in basket)   --- (1)

If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2

From the second statement

Y + 2 = X + 0.5

Subtracting Y from the LHS gives 2 = X - Y + 0.5

Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5  --- (2)

Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg

But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg

Answer:

20 km rate should 7.76

Step-by-step explanation:

Definitions

The variable rate is the rate for every km.

The fixed rate is what is charged for someone just getting on their bicycle.

Givens

Length of race = 6 km

variable rate = 0.22 / km

fixed rate = x

Total cost = 4.68

Formula

Total cost = fixed rate + variable rate * distance

Solution

4.68 = 6*0.22 + x

4.68 = 1.32 + x                       Subtract 1.32 from both sides.

4.68 - 1.32 = 1.32 - 1.32 + x   Combine

3,36 = x

The fixed rate is 3.36

Before getting the answer to the question asked, we should see if we get the same fixed rate for 24 km

Check

Total Cost = fixed rate + variable rate*distance

Total Cost = 8.64

fixed rate = x

variable rate = 0.22

distance = 24 km

8.64 = x + 0.22 * 24                Combine

8.64 = x + 5,28                        Subtract 5.28 from both sides

8.54 - 5,28 = x + 5.28 - 5,28  Combine

3.36 = x which agrees with our first calculation for the fixed rate.

Answer

y = 3.36 + 20*0.22

y = 3.36 + 4.4                           Combine

y = 7.76

The hull speed of a boat when given by the function v = 1.34√l, makes the expression represent the speed of Santa Monica, v = a√b, with a = 1.34, and b = ln - 10, where lₙ is the length of the Nina Pinta. The restriction on lₙ is that lₙ > 10.

In the question, we are asked to express the speed of the boat of Santa Monica in terms of the length, lₙ of the Nina Pinta.

We are informed that the function is represented as v = a√b, for the speed of Santa Monica.

We are given that the hull speed of a boat of length l is given as v = 1.34√l.

Comparing, the speed of Santa Monica v = a√b, to the general formula v = 1.34√l, we get:

a = 1.34, and

b = the length of the boat of Santa Monica.

The length of the boat of Santa Monica is 10 ft. shorter than of Nina Pinta.

Thus, b = lₙ - 10, where lₙ is the length of the boat of Nina Pinta.

Since b has to be positive, as the function involves square root over b, lₙ - 10 > 0, or, lₙ > 10, is the restriction on the length of the boat of Nina Pinta.

Thus, the hull speed of a boat when given by the function v = 1.34√l, makes the expression represent the speed of Santa Monica, v = a√b, with a = 1.34, and b = ln - 10, where lₙ is the length of the Nina Pinta. The restriction on lₙ is that lₙ > 10.
