7x^2 - 12 = 0
7x^2 = 12 | : 7
x^2 = 12/7 | sqrt
x = sqrt(12/7)
x = sqrt(84) / 7
x = 2sqrt(21) / 7
Area of a circle is found using the formula: Area = π * r^2
Using 3.14 for π
Area of the bull'e eye = π * 2^2 = 4π = 4 * 3.14 = 12.56 square inches.
This is 20% of the entire target.
To find the area of the entire target, divide the area of the bull's eye by the percentage:
Area = 12.56 / 0.20 = 62.8 square inches.
Round the answer as needed.
The wind chill equations I have found are more complicated than that.
She would withdraw money for 15 weeks, and after 15 weeks she would have the 20 dollars left, :) hope i helped.
Answer:
Step-by-step explanation:
We have been given that Martha has 8 cubic feet of putting soil in the 3 flowerpots. She wants to put the same amount of soil in each pot.
To find the amount of soil in each pot, we need to divide total soil (8 cubic feet) by number of pots (3) as shown below:
Therefore, Martha needs to put approximately 2.67 cubic feet of soil in each flower pot.
