Answer:
im pretty sure it'd be 76 weeks!
Step-by-step explanation:
one water tank holds 1216 and loses 5 gallons/week
another water tank holds 1520 gallons and loses 9 gallons/week
youd make an equation:
1216-5x=1520-9x
(each side being the amount of water the tank can hold minus the amount it loses per week [x])
heres how you execute the equation:
1216-5x=1520-9x
-5x=1520-1216-9x
-5x=304-9x
-5x+9x=304
4x=304
x=304/4
76
after you do the equation, you get x=76, meaning 76 weeks! :-)

Step-by-step explanation:
Answer: The area of the region covered with small rocks is 49.76 ft²
Step-by-step explanation:
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
The radius of the garden is 4 ft
Therefore,
Area of garden = 3.14 × 4² = 50.24ft²
The length of each side of the square is 10ft.
Area of square = 10² = 100ft²
The area of the region covered with small rocks = Area of the square - area of the circular garden. It becomes
100 - 50.24 = 49.76 ft²
