Answer:
The actual height of the object is 200.2 cm
Step-by-step explanation:
The parameters given are;
The actual height = 154 cm.
The height in the picture = 10 cm.
The height of the object = 13 cm
The scale of the picture is 154 is to 10 or 154:10 which is equivalent to 77:5
Therefore the scale of the actual object height to the image height = 77:5
Where the image of the object = 13 cm
Let the height of the actual object = X, then we then have;
The actual height of the object = 200.2 cm.
Answer:
I will try to do this need time
Step-by-step explanation:
Answer: Option A
Step-by-step explanation:
Note that for the initial year, 1990, the population was 5.3 billion.
The exchange rate is 0.09125 billion per year. In other words, each year there are 0.09125 billion more people.
In year 2 there will be 0.09125 * 2 billion people
In year 3 there will be 0.09125 * 3 billion people
In year 4 there will be 0.09125 * 4 billion people
In year t there will be 0.09125 * t billion of people
So the equation that models the number of people that there will be as a function of time is:
Where is the initial population
billion
r is the rate of increase
billion per year
finally the equation is:
The correct answer is option A.
