If a decagon with side length 4 yd then the area of decagon is 123 square yard.

A decagon is a ten-sided polygon

The side length of decagon is 4 yd.

We have to find the area of decagon

Area of Decagon = 5/2 a²√5+2√5

a is the side length

a=4 yd

Area of Decagon  = 5/2 4²√5+2√5

= 5/2 ×16×√5+2√5

=123 square yard

Hence, if a decagon with side length 4 yd then the area of decagon is 123 square yard.

Answer:

After thirty days with the mentioned use the cost of the device is R$ 507,00.

Step-by-step explanation:

We first need to calculate its total power consumption over the 30 days. Since its turned on four times a day for 2 h and 36 min each, we need to multiply this time by 4 to have the time it's turned on in a day and multiply that by 30 to calculate its total power consumption. Although, we need to convert the time from hours and minutes to only hours, to do that we divide the minutes part by 60 and sum it on the hour part. All of this is done below:

\(t = 2 + \frac{36}{60} = 2.6 \text{ h}\)

\(\text{dayly time} = 4*t = 4*2.6 = 10.4 \text{ h}\)

\(\text{monthly time} = 30*\text{dayly time} = 30*10.4 = 312\text{ h}\)

\(\text{total power consumption} = \text{monthly time}*6500 = 312*6500\\\text{total power consumption} = 2028000 \text{ W} = 2028 \text{ kW}\)

\(\text{total cost} = \text{total power consumption}*0.25\\\text{total cost} = 2028*0.25\\\text{total cost} = 507\)

After thirty days with the mentioned use the cost of the device is R$ 507,00.

The solutions to this system of conics is x = -4 and y = -4 or (x, y) = (-4, -4) after using the substitution method.

It is defined as the curve which is the intersection of cone and plane. There are three major conic sections; parabola, hyperbola, and ellipse (a circle is a special type of ellipse).

It is given that:

The equation of the circle:

(x - 1)² + (y + 4)² = 25

The equation of the ellipse:

(x - 1)²/25 + (y + 4)²/100 = 1

Using substitution method:

[25 - (y + 4)² ]/25 + (y + 4)²/100 = 1

After solving:

(y + 4)² = 0

y = -4

x = -4

Thus, the solutions to this system of conics is x = -4 and y = -4 or (x, y) = (-4, -4) after using the substitution method.

Option 234 cm is the correct option.

The measurement equivalent to 2.34 meters is: 234 cm

To convert meters to centimeters,

you multiply the number of meters by

100.

So, 2.34 meters multiplied by 100 is equal to 234 centimeters.

An object is only identified or classified using numbers on a nominal scale, which is a measuring scale. Only non-numeric (quantitative) factors or situations where numbers have no meaning are often addressed by this assessment.

By increasing the number of metres by 100, one may convert measurements from metres to centimetres. One metre equals one hundred centimetres, or 1 m = 100 cm, as is common knowledge.

Cm is used to represent it in writing. It may also be described as the unit of length in the current metric system, the International System of Units (SI). It is equal to one hundredth of a metre.

Answer:

Step-by-step explanation:

The determinant of matrix "d" would still be 4,

the same as the determinant of matrix "a".

To obtain the matrix "d" from matrix "a" by adding 7 times the third row to the second row, you would perform the following operation:

d = a + 7 × (third row of a added to the second row)

Let's denote the third row of matrix "a" as r3, and the second row as r2. The operation can be written as:

d = a + 7 × r3 + r2

Please note that adding rows of a matrix means adding corresponding elements of the rows.

The determinant of a matrix is not affected by row operations that involve adding multiples of one row to another row.

The given data is as follows:Number of transactions (n) = 26 .Sample mean price  = 2674 dollars .Population standard deviation = 302 dollars .The level of confidence (C) = 99%

An online used car company sells second-hand cars. For 26 randomly selected transactions, the mean price is 2674 dollars.

Assuming a population standard deviation transaction prices of 302 dollars, we have to obtain a 99.0% confidence interval for the mean price of all transactions.

The formula to calculate the confidence interval for the population mean is:

Lower limit of the interval

Upper limit of the interval

The level of confidence (C) = 99%

For a level of confidence of 99%, the corresponding z-score is 2.58.

The given data is as follows:Number of transactions (n) = 26

Sample mean price  = 2674 dollars

Population standard deviation  = 302 dollars

Lower limit of the interval = 2674 - (2.58)(302 / √26)≈ 2449.3 dollars

Upper limit of the interval = 2674 + (2.58)(302 / √26)≈ 2908.7 dollars

Therefore, the 99.0% confidence interval for the mean price of all transactions is [2449.3 dollars, 2908.7 dollars].

The game to be fair, the player should win 60.

In order to determine the fair winnings for this game, we need to calculate the probability of winning and then set it equal to the cost of playing the game.
Step 1: Calculate the probability of winning.
There are two scenarios for winning:
1. First roll is even, and the second roll matches the first.
2. The probability of rolling an even number on a six-sided die is 3/6 or 1/2, since there are three even numbers (2, 4, and 6).
Step 2: Calculate the probability of the second roll matching the first roll.
Since there are 6 sides to the die, the probability of the second roll matching the first is 1/6.
Step 3: Calculate the combined probability of both events.
To find the combined probability of both events, multiply the probabilities: (1/2) × (1/6) = 1/12. So the probability of winning is 1/12.
Step 4: Set up an equation to determine fair winnings.
Let x be the fair winnings for the game. The cost of playing the game is $5. In order for the game to be fair, the expected value (probability of winning multiplied by the winnings) should equal the cost of playing the game:
(1/12) × x = 5
Step 5: Solve the equation for x.
To solve for x, multiply both sides of the equation by 12:
x = 5 × 12
x = 60

The rent of the apartment during the 10th year can be calculated using the formula: Rent = Initial rent * (1 + rate of increase)^n where "Initial rent" is the rent during the first year, "rate of increase" is the percentage increase in rent per year, and "n" is the number of years.

So, for the 10th year, we have:
M Rent = $1600 * (1 + 12.5%)^10
Rent = $1600 * (1 + 0.125)^10
Rent = $1600 * 2.825
Rent = $4520

Therefore, the rent of the apartment during the 10th year of living in the apartment would be $4520. Rounded to the nearest tenth, the rent would be $4520.0.
