78, a constant represents the initial temperature
5000 divided by 0.02 is 100. Only about 100 of the lobsters will be born blue in color. Hope I helped!
Slope is change in y / change in x
Using the two points given:
Slope = (5-4) /(2-4) = 1/-2 = -1/2
slope = -1/2
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
