REASON:

Theorem used: The diagonals of a parallelogram bisect each other.

Let diagonals AC and BD bisect each other at O

So, OA=OC

Now,

x= 6

HOPE IT IS USEFUL

Answer:

Step-by-step explanation:

Parallelogram's diagonals theorem states that the diagonals in a parallelogram must bisect each other.

So for ABCD to be a parallelogram, the two diagonals must be divided in equal sections.

That is given for BD already.

For AC, 3x = 4x - 6

Rearranging, 4x - 3x = 6

x = 6

Answer:

[tex]log_{3}(x . y^\frac{1}{3} / z^5 )[/tex]

Step-by-step explanation:

Given in the question an expression

[tex]log_{3} x+\frac{1}{3}log_{3} y-5log_{3} z[/tex]

To Condense this log into a single log we will use logarithm rules

logb(x^y) = y ∙ logb(x)

[tex]\frac{1}3}log_{3} y = log_{3}y^\frac{1}{3}[/tex]

[tex]5log_{3} z = log_{3} z^5[/tex]

logb(x ∙ y) = logb(x) + logb(y)

[tex]log_{3} x + log_{3}y^\frac{1}{3} = log_{3}(x . y^\frac{1}{3} )[/tex]

[tex]logb(x / y) = logb(x) - logb(y)\\log_{3}(x . y^\frac{1}{3} )- log_{3} z^5[/tex]

= [tex]log_{3}(x . y^\frac{1}{3} / z^5 )[/tex]

So the ratio are 1:2:3:4 and all these add up to 10

Now we divide 360 by 10 resulting to 36

A=(36)

B=(72)

C=(108)

D=(144)

All these add up to 360 and has been divided equally according to the ration provided

Final answer:

To find the measures of the angles in quadrilateral ABCD with ratios 1:2:3:4, we set the angles as x, 2x, 3x, and 4x, and use the fact that their sum equals 360 degrees. Solving for x, we find x to be 36 degrees, which gives us the individual angles as 36 degrees, 72 degrees, 108 degrees, and 144 degrees respectively.

Explanation:

Calculating the Measures of the Angles in a Quadrilateral

Given that the measures of the angles A, B, C, and D in quadrilateral ABCD are in the ratio of 1:2:3:4 respectively, we first need to understand that the sum of the interior angles in a quadrilateral is always 360 degrees. To find the measure of each angle, we should express the ratio in terms of x, which would give us the angles as x, 2x, 3x, and 4x. Summing these and setting them equal to 360 degrees, we get the equation x + 2x + 3x + 4x = 360. Simplifying, we have 10x = 360, which when solved for x yields x = 36 degrees. Therefore, the measures of the angles are:

Angle A = 1x = 36 degrees

Angle B = 2x = 72 degrees

Angle C = 3x = 108 degrees

Angle D = 4x = 144 degrees

Hence, each angle's measure has been found using the given ratio and the property of the sum of interior angles in a quadrilateral.

Final answer:

The dimensions of the price tag are 9 cm by 4 cm, which are found by solving two equations derived from the given area and perimeter.

Explanation:

The student is asking for the dimensions of a rectangular price tag that has an area of 36 square centimeters and a perimeter of 26 centimeters. To solve this, we need to use two formulas: one for area (A = length × width) and one for perimeter (P = 2 × (length + width)).

First, let's denote the length of the rectangle by l and the width by w. The given area, 36 cm2, implies that l × w = 36.

Second, we know the perimeter is 26 cm, which gives us the equation 2 × (l + w) = 26. Dividing both sides by 2, we get l + w = 13.

This system of equations can be solved using substitution or elimination. If we rearrange the perimeter equation to express one variable in terms of the other (for instance, w = 13 - l), we can then substitute this expression into the area equation. Solving for l and w afterwards will give us the required dimensions.

Through solving, we find that the dimensions of the rectangle are 9 cm by 4 cm, since 9 × 4 = 36 and 2(9 + 4) = 26.

To determine how many kilometers east Santos walked, we can use the Pythagorean theorem to find the distance traveled for each leg of the journey.

To determine how many kilometers east Santos walked, we need to use the Pythagorean theorem to find the distance traveled for each leg of the journey. Since he ends up 5 kilometers away from his starting position, we can form a right triangle with the hypotenuse representing the total distance walked.

Let's assume Santos walked x kilometers east. The other leg of the triangle represents the 2 kilometers south he walked. Using the Pythagorean theorem, we have x2 + 22 = 52.

This simplifies to x2 + 4 = 25. Subtracting 4 from both sides gives us x2 = 21. Taking the square root of both sides, we find that x ≈ 4.58. Therefore, Santos walked approximately 4.58 kilometers east.

The volume of a cylinder (sculpture) is equal to

[tex]V=\pi r^{2}H[/tex]

In this problem we have

[tex]r=12/2=6\ ft[/tex] ----> the radius is half the diameter

[tex]H=h\ ft[/tex]

substitute the values

[tex]V=\pi (6^{2})(h)=36 \pi h\ ft^{3}[/tex]

Answer:

36πh cubic feet

Step-by-step explanation:

To find the volume of a cylinder  with a diameter of 12 feet and a height of h feet, we must know the formula for finding the volume of  a cylinder.

The volume V of a cylinder with a radius r and a height h is given as

V = πR^2h

where π = 22/7

Given that the radius of the given cylinder is 12 feet, the radius r

= 12/2 feet

= 6 feet

The volume v

= π * 6^2 * h

= 36πh cubic feet

Step-by-step explanation:

x^2 - 8x + 7 = 0

(x - 1)(x - 7) = 0

x= 1, 7.

Answer:

x = 1

Step-by-step explanation:

Please express exponentiation using the symbol  " ^ "  :  x^2 - 8x + 7 = 0

Let's solve this equations using "completing the square:"

x^2 - 8x + 7 = 0

1) Identify the coefficient of the x term.  Here it's -8.

2) take half of that and square it:  we get (-4)² = 16

3) insert " +16 - 16 " between the 8x and the 7:

        x^2 - 8x +  16 - 16  +7 = 0

4)  Rewrite this perfect square:

          (x - 4)² - 16 + 7 = 0  ->   (x - 4)^2 = 9

5)  Solve for (x -4) by taking the square root of both sides:

           x - 4 ± sqrt(9)    ->  x - 4 ± 3

6)  Solve for x:  x = 4  ± 3, or x = 7 and x = 1.  

7)  Take the lesser root of 7 and 1.  That would be x = 1.  Answer B is correct.

Answer:

0.731 < p < 0.775

Step-by-step explanation:

We have a sample proportion of 753/1000 = 0.753

We need to construct a 90% confidence interval for the population proportion.  Since n > 30, we use the corresponding z-value of 1.645.  

See attached photo for the formulas and construction of the confidence interval.

The 90% confidence interval for the proportion of American adults who think exercise is an important part of daily life is 0.749 to 0.757.

To find the 90% confidence interval for the proportion of American adults who think exercise is an important part of daily life, we can use the formula for the confidence interval of a proportion. The formula is: CI = p ± Z * sqrt((p * (1-p))/n), where p is the sample proportion, Z is the z-score corresponding to the desired confidence level, and n is the sample size.

First, we need to calculate the sample proportion: p = 753/1000 = 0.753.

Next, we need to find the z-score for a 90% confidence level. Looking up the z-score in the standard normal distribution table, we find that the z-score for a 90% confidence level is approximately 1.645.

Now we can plug in the values into the formula: CI = 0.753 ± 1.645 * sqrt((0.753 * (1-0.753))/1000).

Calculating the expression inside the square root gives us approximately 0.0027. Plugging this value into the formula gives us the 90% confidence interval for the proportion: CI = 0.753 ± 1.645 * 0.0027.

Calculating this expression gives us the lower and upper bounds of the confidence interval: CI = 0.753 ± 0.0044.

Answer:

B.

Step-by-step explanation:

Because the graph shown is not constant, if you look at when it hits a whole unit. It is increasing because it is moving right.

The true statement is:

B.  

The function indicates that the number of members is increasing at a rate that is not constant.

We could write the data points as is given on the graph as follows:

  x       y

  0      40

  1       50

  2      60

  3      80

  4      100

  5      120

  6      150

  7      190

  8      240

  9      300

  10     370

Hence, the rate of change from x=0 to x=1 is:

[tex]Rate=\dfrac{50-40}{1-0}\\\\\\Rate=\dfrac{10}{1}\\\\\\Rate=10[/tex]

Rate of change from x=3 to x=5 is:

[tex]Rate=\dfrac{120-80}{5-3}\\\\\\Rate=\dfrac{40}{2}\\\\\\Rate=20[/tex]

Hence, the rate is not constant.

Also we could see that with the increasing value of x the y-value also increases.

                  Hence, option: B is the correct answer.

Answer:

D) 8

Step-by-step explanation:

Given function for height =  f(x) = 80(0.5)^x

It shows that the height of ball after any bounce can be calculated by putting bounce number in place of x in this equation.

so, height after first bounce f(1) is calculated by placing 1 in place of x

f(1) = 80(0.5)^1

f(1) = 80(0.5)

f(1) = 40

Similarly, the height after 4th bounce f(4)

f(4) = 80(0.5)^4

f(4) = 80(0.0625)

f(4) = 5  

Therefore, the height of 1st bounce is 40/5 = 8 times higher than the fourth bounce. So, option D is correct.

The first bounce is 8 times higher than the fourth bounce. Option D (8) is correct.

The height of the bouncing ball is given by the function f(x) = 80(0.5)^x, where x represents the number of bounces. To find how many times higher the first bounce is than the fourth bounce, we'll calculate the heights for f(1) and f(4) and then compare them.

Therefore, the first bounce is 8 times higher than the fourth bounce, corresponding to option D (8).
