Answer:
12
Step-by-step explanation:
When you multiply both sides of the equation you are multiplying them by the common denominator. In this case, the common denominator is 12. So multiply, then you have the most simplified problem of 2x=9x-8.
Answer:
Step-by-step explanation:
r = 4.9 miles
Area of circle = πr²
= 3.14 * 4.9 * 4.9
= 75.39 square miles
Find the equation for the circle 12 seconds after the anchor is dropped
Please write all the steps it’s for my summer school test and I need it done quick as possible thanks.
Answer:
The equation for the circle 12 seconds after the anchor is dropped is x^2 + y^2 = 360,000
Step-by-step explanation:
To find the equation for the circle 12 seconds when the radius of the ripple increases at a rate of 50 cm/s, the circle radius will be;
50 * 12 = 600 cm
Then place the equation inform of Pythagoras equation which is;
x^2 + y^2 = r^2
Where r is the radius
x^2 + y^2 = 600^2
x^2 + y^2 = 360,000
Then, the equation for the circle 12 seconds after the anchor is dropped is x^2 + y^2 = 360,000
The area of a square is found by S^2 where S is the length of a side.
The garden and path are 11 feet wide, so the total area for both is 11^2 = 121 square feet.
The length of a side of just the garden would be 11 - 4 ( 2 feet of path on both sides) = 7 feet
The area of the garden would be 7^2 = 49 square feet.
the area of the path would be the total area minus the area of the garden: 121-49 = 72 square feet.
