Therefore in 7 centimeters there are 0.07 meters.
7 cm is a whole number while 0.07 m is a decimal number
Scientific Notation of each numbers
=> 7 cm = 7 x 10^0
=> 7 m = 1 x 10^-2

damaskus [11]

the area of the piece of land that is not part of the garden is 28,486ft^2 .

<u>Step-by-step explanation:</u>

Here we have , a piece of land 120 ft by 240 ft contains a circular garden. surrounding the garden, there is a circular fence that is 20 ft in diameter.  We need to find what is the area of the piece of land that is not part of the garden . Let's find out:

Let's calculate area of land and circular garden , and in order to find the area of the piece of land that is not part of the garden we will subtract area of circular garden from land !

Area of Land:

Area of land is given by

⇒ length(width)

⇒ 120(240)

⇒ 28,880ft^2

Area of Garden:

Area of circular garden given by

⇒ \pi r^2

⇒ \pi (\frac{D}{2})^2

⇒ \pi (\frac{20}{2})^2

⇒ \pi (10)^2

⇒ 100\pi

⇒ 100(3.14)

⇒ 314ft^2

Hence , the area of the piece of land that is not part of the garden is 28,880-314 = 28,486 . Therefore , the area of the piece of land that is not part of the garden is 28,486ft^2 .

Evaluate 2x for each value of x. Write your answers in simplest form. Show your work!
Liono4ka [1.6K]

1. 1/2

2.2/3

3. 1

4. 1/3

5. 2/7

6. 1/4

7. 4/3

8. 3/2

<h3>How to evaluate the value</h3>

To find 2x of the vale of x, we have to multiply the value of 'x' by 2

1. x = 1/4

2x = 2 * \frac{1}{4} ⇒ \frac{2}{4} ⇒\frac{1}{2}

2. x = 1/3

2x = 2 * \frac{1}{3} ⇒\frac{2}{3}

3. x = 1/2

2x = 2* \frac{1}{2} ⇒ \frac{2}{2} ⇒ 1

4. x= 1/6

2x = 2* \frac{1}{6} ⇒ \frac{2}{6} ⇒ \frac{1}{3}

5. x = 1/ 7

2x = 2 * \frac{1}{7} ⇒ \frac{2}{7}

6. x = 1/8

2x = 2 * \frac{1}{8} ⇒ \frac{2}{8} ⇒ \frac{1}{4}

7. x = 2/3

2x = 2 * \frac{2}{3} ⇒ \frac{4}{3}

8. x = 3/4

2x = 2 * \frac{3}{4} ⇒ \frac{6}{4} ⇒ \frac{3}{2}
