In 1964, paleontologists discovered the bones of a new species of dinosaur. The age of the dinosaur was estimated using potassium-40 dating of rocks surrounding the bones. Analysis of these rocks indicated that 88.7% of the original amount of the potassium-40 was still present. The decay model for potassium-40 is Upper A equals Upper A 0 e Superscript negative 0.52912 t Baseline comma where t is in billions of years. Let Upper A equals 0.887 Upper A 0 in this decay model and estimate the age of the bones of the dinosaur.

The area of the enlarged photograph is 87.5 square inches.
What is the area of the enlarged photograph?
The first step is to determine the area of the photograph before it was enlarged. A photograph has the shape of a rectangle. So, the formula for the area of a rectangle would be used.
Area = length x width = 7 x 5 = 35
Area of the enlarged photograph = 2.5 x 35 = 87.5

Answer:
answer is B) 87.5 squared inches.
Step-by-step explanation:
The original dimensions of the photograph were 5 inches by 7 inches so, the area of the original photograph can be computed as the area of a rectangle:
.
So
squared inches.
Now, for computing the area of a photograph of 250% the size of the original we use a simple rule of three:
35 squared inches -------- 100%
X squared inches --------- 250%
By this, we have:

Answer:
11,180
Step-by-step explanation:
The usual assumption for organic growth is that it is exponential. Here, the number increased by a factor of 1000/200 = 5 in 8 hours. For t in hours, a model for population might be ...
b = (initial value)·(growth factor)^(t/(period of growth))
b = 200(5^(t/8))
Using t = 20, the predicted population is ...
b = 200(5^(20/8)) = 200·5^2.5 ≈ 11,180
There might be about 11,180 bacteria in 20 hours.
