Squares have equal side lengths, so that is why the question is only asking for one side length.

The area of a square is calculated using the formula s^2, where s stands for a side of the square.

To find the length of one side of the park, you can take the given area (3,600 m^2) and square root it. This would give you the length of one side of the square park.

√3,600 = 60

The length of one side of the park is 60 meters.

The length of one side of the square park with an area of 3600 square meters is 60 meters.

Given that the area of the square park is 3600 square meters, we can calculate the length of one side by taking the square root of the area. This is because the area of a square is calculated by squaring the length of one side (side length X side length). So, if we reverse this process by taking the square root, we find the length of one side.

So, "the length of one side of the park is the square root of 3600 which equals 60 meters".

Answer:

b

Step-by-step explanation:

Step 1. Simplify 7/9(6x - 36) to 7(6x - 36)/9

23 = 7(6x - 36)/9 + 9

Step 2. Factor out the common term

23 = 7 * 6(x - 6)/9 + 9

Step 3. Simplify 7 * 6(x - 6) to 42(x - 6)

23 = 42(x - 6)/9 + 9

Step 4. Simplify 42(x - 6)/9 to 14(x - 6)/3

23 = 14(x - 6)/3 + 9

Step 5. Subtract 9 from both sides

23 - 9 = 14(x - 6)/3

Step 6. Simplify 23 - 9 to 14

14 = 14(x - 6)/3

Step 7. Multiply both sides by 3

14 * 3 = 14(x - 60

Step 8. Simplify 14 * 3 to 42

42 = 14(x - 6)

Step 9. Divide both sides by 14

42/14 to x - 6

Step 10. Simplify 42/14 to 3

3 = x - 6

Step 11. Add 6 to both sides

3 + 6 = x

Step 12. Simplify 3 + 6 to 9

9 = x

Step 13. Switch sides

x = 9

Final answer:

The solution to the equation is x = 9.

Explanation:

To solve for x, we need to isolate it on one side of the equation.

Let's start by distributing 7/9 to the terms inside the parentheses:

23 = (7/9)(6x - 36) + 9

Next, simplify the expression inside the parentheses:

23 = (7/9)(6x) - (7/9)(36) + 9

Now, multiply 7/9 with 6x and 36:

23 = (42/9)x - (252/9) + 9

Simplify the fractions:

23 = (14/3)x - (28/1) + 9

Combining the constants:

23 = (14/3)x - 19

Add 19 to both sides:

23 + 19 = (14/3)x

Now we have:

42 = (14/3)x

To isolate x, divide both sides by 14/3:

42 / (14/3) = x

Simplify the expression:

42 * (3/14) = x

Now, calculate:

x = 9

The answer is (2, 1)

We can solve this by using midpoint formula

[tex]M = (x_{1} + x_2)/2, (y_1 + y_2} ) /2[/tex]

because in a plane the coordinates of midpoint of a line is the average of each other coordinates.

So,

[tex]x_1 = -1, x_2 = 5[/tex]

[tex]y_1 = 0. y_2 = 2[/tex]

Putting values in formula as

[tex]M = (-1+5) / 2, (0+2) / 2[/tex]

[tex]M = (2, 1)[/tex]

Answer:  The required co-ordinates of the endpoint D are (-7, -2).

Step-by-step explanation:  Given that the midpoint of CD is E (-1,0) and one endpoint is C (5,2).

We are to find the co-ordinates of the other endpoint D.

Let (x, y) represents the co-ordinates of the endpoint D.

We know that

the co-ordinates of the midpoint of a line segment withe endpoints (a, b) and (c, d) is given by

[tex]\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]

Therefore, according to the given information, we have

[tex]\left(\dfrac{5+x}{2},\dfrac{2+y}{2}\right)=(-1,0)\\\\\\\Rightarrow \dfrac{5+x}{2}=-1\\\\\Rightarrow 5+x=-2\\\\\Rightarrow x=-2-5\\\\\Rightarrow x=-7[/tex]

and

[tex]\dfrac{2+y}{2}=0\\\\\Rightarrow 2+y=0\\\\\Rightarrow y=-2.[/tex]

Thus, the required co-ordinates of the endpoint D are (-7, -2).

Answer: B) [tex]\frac{2-0}{3-0}=\frac{4-2}{6-3}[/tex]

Step-by-step explanation:

1. You can calculate the slope by applying the following formula:

[tex]m=\frac{y_{2}.y_{1}}{x_{2}-x_{1}}[/tex]

2. The point A is (0,0) and the point C is (3,2).

Where:

[tex]y_{2}=2\\y_{1}=0\\x_{2}=3\\x_{1}=0[/tex]

3. The point C is (3,2) and the point E is (6,4).

Where:

 [tex]y_{2}=4\\y_{1}=2\\x_{2}=6\\x_{1}=3[/tex]

4. Then, you have:

[tex]\frac{2-0}{3-0}=\frac{4-2}{6-3}[/tex]

[tex]\frac{2}{3}=\frac{2}{3}[/tex]

5. Therefore, the slope of AC is equal of the slope CE.

4,002,000

answer is D

By Subtracting the given Expression 9,002,000 - 5•[tex]10^6[/tex] we get Option C. 4.002 x [tex]10^4[/tex].

To subtract 5 • [tex]10^6[/tex] from 9,002,000, we simply perform the arithmetic operation as follows:

9,002,000 - 5 • [tex]10^6[/tex]

Step 1: Subtract 5 • [tex]10^6[/tex] from 9,002,000

= 9,002,000 - 5 • [tex]10^6[/tex]

= 9,002,000 - 5,000,000

Step 2: Perform the subtraction

= 9,002,000 - 5,000,000

= 4,002,000

Now, we have the result of 4,002,000. However, we need to write this answer in scientific notation.

In scientific notation, a number is written as a product of two parts: a coefficient and a power of 10. The coefficient must be greater than or equal to 1 and less than 10.

To express 4,002,000 in scientific notation, we move the decimal point to the left until we have a number between 1 and 10.

Since 4,002,000 = 4.002 × 1,000,000, we can write it as 4.002 × [tex]10^6[/tex].

However, our options are given in terms of powers of 10 from [tex]10^3[/tex] to [tex]10^6[/tex]. We can rewrite 4.002 × [tex]10^6[/tex] as 4.002 × ([tex]10^6[/tex] ÷ [tex]10^2[/tex]) = 4.002 × [tex]10^{(6-2)}[/tex]

                                                                                = 4.002 × [tex]10^4[/tex].

Therefore, the correct answer is option C, 4.002 × [tex]10^4[/tex].

In summary, to find the result of 9,002,000 - 5 • [tex]10^6[/tex], we perform the subtraction to get 4,002,000, and then we express it in scientific notation as 4.002 × [tex]10^4[/tex]. Option C is the correct choice.

I think the answer to this question is 306,040,608. If we are supposed to write it out then it is (3 × 100,000,000) + (6 × 1,000,000) + (4 × 10,000) + (6 × 100) + (8 × 1)

We can see here that Paula will need 5 packages of small juice boxes and 3 packages of yogurt treats to have the exact same number of each item, resulting in a total of 30 juice boxes and 30 yogurt treats.

Since small juice boxes come in packages of 6 and yogurt treats come in packages of 10, Paula wants to have the exact same number of each item. This means that both the number of juice boxes (J) and the number of yogurt treats (Y) must be multiples of the least common multiple (LCM) of 6 and 10.

The LCM of 6 and 10 is 30.

So, Paula needs to have a multiple of 30 for both the number of juice boxes and the number of yogurt treats.

To find the values of J and Y, we can choose any multiple of 30.

Let's say Paula decides to have 30 juice boxes (J = 30) and 30 yogurt treats (Y = 30).

Now, let's find out how many packages of each she will need:

For juice boxes (packages of 6): J / 6 = 30 / 6 = 5 packages

For yogurt treats (packages of 10): Y / 10 = 30 / 10 = 3 packages

So, Paula will need 5 packages of small juice boxes and 3 packages of yogurt treats to have the exact same number of each item, resulting in a total of 30 juice boxes and 30 yogurt treats.

Setting up algebraic equations to represent the costs of each club, one can solve for the number of months where the costs are the same. The cost of both health clubs is equal for 11 months.

In mathematics, problems like this can be solved using algebra, setting the cost of club 1 equal to the cost of club 2 and then solving for the variable, in this case, the number of months for which the costs are equal. Club 1 charges a $44 sign-up fee and $30 per month, which can be written as 44 + 30m (where 'm' represents the number of months). Club 2 charges a $99 sign-up fee and $25 per month, which can be written as 99 + 25m. Set these two equations equal: 44 + 30m = 99 + 25m and solve for m. Subtract 25m from both sides to get 5m = 55, then divided both sides by 5 to find m = 11. So, the cost of membership at these two health clubs is the same for 11 months.

To undo a square root in an equation, you square both sides of the equation. This will eliminate the square root on one side and gives you the original value under the square root. It simplifies the equation, making it easier to solve.

To undo a square root in an equation that includes a radical expression, you have to square that part of the equation. Here is an example to illustrate this:

Suppose you have the equation √x = 2. To undo the square root, you need to square both sides of the equation: (√x)² = 2². This operation results in the equation x = 4.

Remember, when squaring a square root, the result is the original number under the radical. Therefore, the process of 'undoing' the square root is to square the radical expression. This helps us to have equations in a simpler form, which further makes it easier for us to solve.

The number is 400.

To find out how many hundreds Mai has, let's understand that each ten is equal to 10. So, if Mai has 40 tens, we can calculate how many ones that is in total:

40 tens * 10 = 400 ones

Now, since there are 100 ones in one hundred, we divide the total number of ones by 100 to find out how many hundreds Mai has:

400 ones / 100 = 4 hundreds

So, Mai has 4 hundreds.

Now, let's write the number:

If Mai has 4 hundreds, it means the digit in the hundreds place is 4. Since she has no tens, the digit in the tens place is 0. And since she has no ones, the digit in the ones place is 0.

An equivalent ratio to 8:4 is 2:1. This is found by simplifying the original ratio by dividing both numbers by their greatest common divisor, which is 4.
