final answer: 11 songs.

The largest absolute value is |29,400|, and the smallest absolute value is |667|.

The given expression |3 × 10^4 - 6 × 10^2| equals |30000 - 600|, which simplifies to |29,400|. This represents the largest possible absolute value using the digits 1 to 9. It is the largest because it maximizes the value by using the highest digits (9 and 8) in the tens of thousands and hundreds places, respectively.

To find the smallest possible answer, we need to arrange the remaining digits (1, 2, 3, 4, 5, 6, and 7) to minimize the value. Since we want to subtract the largest possible number from the smallest, we arrange the digits in ascending order, resulting in |1,234 - 567|.

Calculating this expression gives us |667|, which represents the smallest possible absolute value using the remaining digits. It is the smallest because it minimizes the value by using the lowest digits (1, 2, 3, 4, 5, 6, and 7) in their respective places.

\(x= \boxed{25}\;\; \sf meters\)

\(y= \boxed{15}\;\; \sf meters\)

\(z= \boxed{58}\;\; \sf degrees\)

Step-by-step explanation:

Similar Triangles

If ΔWXY ~ ΔQRS then:

Therefore:

\(\implies \sf WX : QR = XY : RS = WY : QS\)

\(\implies (15+x) : 30 = 20 : y = 32 : 24\)

\(\implies \dfrac{15+x}{30}=\dfrac{20}{y}=\dfrac{32}{24}\)

Solving for x:

\(\implies \dfrac{15+x}{30}=\dfrac{32}{24}\)

\(\implies 15+x=\dfrac{30 \cdot 32}{24}\)

\(\implies x=\dfrac{30 \cdot 32}{24}-15\)

\(\implies x=25\)

Solving for y:

\(\implies \dfrac{20}{y}=\dfrac{32}{24}\)

\(\implies 20 \cdot 24=32y\)

\(\implies y=\dfrac{20 \cdot 24}{32}\)

\(\implies y=15\)

If ΔWXY ~ ΔQRS then:

Therefore, solving for z:

\(\implies m \angle W = m \angle Q\)

\(\implies 40^{\circ} = z-18^{\circ}\)

\(\implies z=40^{\circ} +18^{\circ}\)

Given:

A regular pentagon with a side length of 11.8 inches and a dotted line from center to middle of side of 8.1 inches.

To find:

The area of the regular polygon.

Solution:

We have,

Side length = 11.8 inches

Length of Apothem = 8.1 inches

Area of a triangle is

\(Area=\dfrac{1}{2}\times base\times height\)

A regular pentagon has 5 equal sides and equal interior angles. The lines from the center to the vertices divide the pentagon in 5 equal triangle.

Area of one triangle is

\(A_1=\dfrac{1}{2}\times \text{Side length}\times \text{Apothem}\)

\(A_1=\dfrac{1}{2}\times 11.8\times 8.1\)

\(A_1=47.79\)

Area of five equal triangle is

\(A=5\times A_1\)

\(A=5\times 47.79\)

\(A=238.95\)

So, the area of the pentagon is 238.95 square inches.

Therefore, the correct option is B.

The missing ordered pairs that satisfy the equation y = 2x + 4 are (3, 10) and (2, 8).

The equation given is y = 2x + 4. To compute the missing x and y values, we need to substitute the given ordered pairs into the equation and solve for the missing variable.

Let's assume we have an ordered pair (x, y) that satisfies the equation y = 2x + 4.

For example, let's say one missing value is x = 3. We can substitute this into the equation:

y = 2(3) + 4

y = 6 + 4

y = 10

So, the missing ordered pair is (3, 10).

Similarly, if another missing value is y = 8, we can substitute this into the equation and solve for x:

8 = 2x + 4

4 = 2x

x = 2

So, the missing ordered pair is (2, 8).

In summary, the missing x and y values that satisfy the equation y = 2x + 4 are (3, 10) and (2, 8).

Answer:

Answer:

\(y-x = 16\)

Step-by-step explanation:

Given

Set 1: (9,5,y,2,x)

Set 2: (8,x,4,1,3)

Required

(y - x)

First the mean values of set 1 and set 2 has to be calculated

For set 1

\(Mean _1 = \frac{(9+5+y+2+x)}{5}\)

Collect like terms

\(Mean _1 = \frac{9+5+2+y+x}{5}\)

\(Mean _1 = \frac{16+ y+x}{5}\)

For set 2

\(Mean _2 = \frac{(8+x+4+1+3)}{5}\)

Collect like terms

\(Mean _2 = \frac{8+4+1+3+x}{5}\)

\(Mean _2= \frac{16+ x}{5}\)

Given that the mean of set 1 is twice the mean of set 2;

\(Mean_1 = 2Mean_2\)

\(\frac{16+ y+x}{5} =2 * \frac{16+x}{5}\)

Multiply both sided by 5

\(5 * \frac{16+ y+x}{5} = 5 * 2 * \frac{16+x}{5}\)

\(16+ y+x = 2 * (16+x)\)

Open bracket

\(16+ y+x = 32 + 2x\)

Subtract 16 from both sides

\(16+ y+x- 16 = 32 + 2x - 16\)

\(16 - 16 + y+x = 32 - 16 + 2x\)

\(y+x = 16 + 2x\)

Subtract 2x from both sides

\(y+x-2x = 16 + 2x-2x\)

\(y-x = 16\)

At least 75% of the data might very well fall between $3.25 and $3.81. According to Chebyshev's theorem, at least 75% of the value systems in a distribution are well within 2 the mean standard deviation.

A delivery has at least 89% of its values inside of three of the mean's standard deviation.

We have the following in this problem:

Mean = $3.53

$0.14 is the standard deviation.

Using Chebyshev's Theorem, determine the range that contains least 75% of the information will live.

The total amount the man had = 52,200 rupees. Out of this, he gave 21,750 rupees to his son, 13,050 rupees to his daughter, and 17,400 rupees to his wife , the total amount given away by the man = 21,750 + 13,050 + 17,400 = 52,200 rupees.

A man gave 5/12 of his money to his son, 3/7 of the remainder to his daughter, and the remaining to his wife. If his wife gets Rs. 8,700, what is the total amount?

The given problem can be solved using the concept of ratios and fractions. Let us solve the problem step-by-step.Assume the man had x rupees with him.The man gave 5/12 of his money to his son.

The remaining amount left with the man = x - 5x/12= (12x/12) - (5x/12) = (7x/12)The man gave 3/7 of the remainder to his daughter.'

Amount left with the man after giving it to his son = (7x/12)The amount given to the daughter = (3/7) x (7x/12)= (3x/4)The remaining amount left with the man = (7x/12) - (3x/4)= (7x/12) - (9x/12) = - (2x/12) = - (x/6) (As the man has given more money than what he had with him).

Therefore, the daughter's amount is (3x/4) and the remaining amount left with the man is (x/6).The man gave all the remaining amount to his wife.

Therefore, the amount given to the wife is (x/6) = 8700Let us find the value of x.x/6 = 8700 x = 6 x 8700 = 52,200

Therefore, the man had 52,200 rupees with him.He gave 5/12 of his money to his son. Therefore, the amount given to his son is (5/12) x 52,200 = 21,750 rupees.

The remaining amount left with the man = (7/12) x 52,200 = 30,450 rupees.He gave 3/7 of the remainder to his daughter. Therefore, the amount given to his daughter is (3/7) x 30,450 = 13,050 rupees.

The amount left with the man = (4/7) x 30,450 = 17,400 rupees.The man gave 17,400 rupees to his wife.
