You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.
The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.
We can deduce that, if x is the number of people between 16 and 19, we have
So, by the relation between the two graphs, we can deduce the total population for each age group.
25/9
9×2=18
18+7=25
Put answer over denominator

Answer:29503.49
Step-by-step explanation:
Perimeter is just the addition of the side lengths so add them together:
5c+6 + 2c+5 = 7c+11
Option D.
Answer:
Building's actual height 32 meters
Building's shadow height 20 meters
Person's shadow height 1.2 meters
Person's actual height = ?
Find the person's actual height:
This is a proportion problem.
Actual height to shadow height
Building = Person
32 : 20 = x : 1.2
32 * 1.2 = 20 * x
38.4 = 20x
38.4/20 = 20x/20
1.92 = x
The person's actual height is 1.92 meters long.
32 : 20 = 1.92 : 1.2
32/20 = 1.60
1.92/1.2 = 1.60
