Answer:
C. d < 2
Step-by-step explanation:
Note that the dot is open, which means that it is not including the number 2 (as the dot is on 2), so you use either < or >. Now, note that the arrow is pointing towards the left, or <em>less than</em>. This means you will use < as your sign.
d < 2 is your answer

Answer:
5.24
Step-by-step explanation:
7700 * 0.00068 = 5.236
Remember that 100% is 1, 10% is 0.1, 1% is 0.01, and then for you 0.068% is 0.00068. When a question is asking for a percentage of a number multiply it by the percentage.
Answer:
![128\text{ ft}^{2}](https://tex.z-dn.net/?f=128%5Ctext%7B%20ft%7D%5E%7B2%7D)
Step-by-step explanation:
We have been given that the area of a square is given by
, where x is the length of one side.
Mary's original garden was in the shape of a square. She has decided to double the area of her garden. So the new area of Mary's garden will be 2 times the area of original garden.
We can represent this information in an equation as:
![\text{Area of Mary's new garden}=2x^{2}](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20Mary%27s%20new%20garden%7D%3D2x%5E%7B2%7D)
Therefore, the expression
will represent the area of Mary's new garden.
To evaluate the area of new garden, if the side length of Mary's original garden was 8 feet, we will substitute x equals 8 in our expression.
![\text{Area of Mary's new garden}=2(8\text{ ft})^{2}](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20Mary%27s%20new%20garden%7D%3D2%288%5Ctext%7B%20ft%7D%29%5E%7B2%7D)
![\text{Area of Mary's new garden}=2*64\text{ ft}^{2}](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20Mary%27s%20new%20garden%7D%3D2%2A64%5Ctext%7B%20ft%7D%5E%7B2%7D)
![\text{Area of Mary's new garden}=128\text{ ft}^{2}](https://tex.z-dn.net/?f=%5Ctext%7BArea%20of%20Mary%27s%20new%20garden%7D%3D128%5Ctext%7B%20ft%7D%5E%7B2%7D)
Therefore, the area of Mary's new garden will be 128 square feet.
