To the nearest hundred it is 100.
Answer:
Step-by-step explanation:
Since, According to the question,
Total mice die in 1991 = 8064483601014110592
Total changes in the population of mice in 1991 = 2.946495792e 19
Since,
The total changes in the population of the mice in 1991= difference between the population of total mice born and the total mice die.
⇒ 2.946495792e 19 = total mice born on 1991 - 8064483601014110592
⇒ total mice born on 1991 = 2.946495792e 19 + 8064483601014110592
⇒ total mice born on 1991 = 3.7529442e+19
Thus, On 1991 mice were born.
Note: Here, we assume that the mice born is more than mice dying because the population of mice is increasing every year exponentially.
It would be -1/2 simplified and 12/-6 not simplified
Answer: ~54.54 units squared, or 25*pi - 24
Step-by-step explanation:
To find this, we need to find both the area of the triangle and circle, and then subtract the area of the triangle from the area of the circle.
Area of triangle:
Area of circle:
To find the radius, we first need to find the hypotenuse of the triangle, which happens to be the diameter of the circle.
Pythagorean Theorem: , where a and b are sides and c is the hypotenuse.
6^2 + 8^2 = c^2
36 + 64 = 100, c = 10
Knowing that the diameter is 10, we also know that the radius is 5.
Area of the circle with a radius of 5 is 25*pi, or 78.54~
Area of the triangle with side lengths of 6 and 8 is 24.
78.54 - 24 = 54.54 units squared.
Answer:
x = 20
Step-by-step explanation:
3x - 10 = x + 30
2x = 40
x = 20
