<span>The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15x15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards.</span>
729. You just do 9 to the power of 3 or 9^3 and you will get 729. If it is not allowed, the answer is 504.(9 x 8 x 7)
Namely, how many times does 1/3 go into 5/8? well, is their quotient,
3x^2 + 6x - 2 = 0
discriminant = b^2 - 4ac; where a = 3, b = 6 and c = -2
d = 6^2 - 4(3)(-2)
d = 36 + 24
d = 60
Answer:
The integer that represents the change in the temperature each week = 5
The temperature of the weather drops 5°F each week
Step-by-step explanation:
The given parameters regarding the weather are;
The range over which the temperature dropped = 20°F
The duration over which the temperature dropped = 4 weeks
The rate at which the weather dropped each week = The same amount (constant rate)
Therefore, we have;
For a constant rate of change, the rate of change of the temperature of the weather, m, is given as follows;
m = (The change in the temperature)/(The duration of the change)
m = 20°F/(4 weeks) = 5°F/week
The integer that represents the change in the temperature each week = 5
