Answer:
2,016.67 sq. cm
Step-by-step explanation:
Given the approximate ratio of the sides of a rectangle as 3:4:5.
Total ratio = 3+4+5 = 12
Area of the rectangle = 1/2*base *height
get the base;
base = 3/12 * 220
Base = 55cm
Get the height
Height = 4/12 * 220
Height = 880/12
Height = 73.3cm
Area = 1/2 * 55 * 73.3
Area = 2,016.67 sq. cm
Answer:
1) f(g(-2))=-3, 2) g(f(0))=5
Step-by-step explanation:
1)f(g(-2))
First, g(-2) means that x=-2. Hence, you must find the value of g(x) in the table when x=-2. You can see that, when x=-2, g(-2) = -3.
Next, you must find f(-3) in the graph, where x=-3. You can see in the graph that, when x=-3, f(-3) = -2.
Therefore, f(g(-2))=-3
2) g(f(0))
In the case, we must apply the inverse procedure. First, check in the graph that, when x=0, f(0) =1.
Next, we must look at the table and see that, when x=1, g(1)=5. Hence,
g(f(0))=5
If the train can carry 78 people and it makess 99 trips,
the greatest number of people will be
78*99= 7722
