Answer: x=3.2 AC= 42.8
Step-by-step explanation:
As point B lies at segment AC AC=AB+BC
Otherwise we can write the equation
5x+9x-2=11x+7.6
14x-2=11x+7.6
14x-2+2=11x+7.6+2
14x=11x+9.6
14x-11x=11x-11x+9.6
3x=9.6
x=9.6:3
x=3.2
AC= 11*x+7.6= 11*3.2+7.6=35.2+7.6=42.8
Answer: C.) 0.4
Explanation: 8/20 chances -> 2/5 -> .4
Answer:
15,000 people
Step-by-step explanation:
This is the question of ratio, it is the quantitative relationship of two number.
In this survey a ratio of 66 people out of 110 is defined as living in apartment, based on this ratio we can estimate the total numbers of people living in apartments.
Total population of the town = 25,000 people
Ratio of people living in apartment = 66 / 110 = 0.6
Town people living in apartment = 25,000 x 0.6 = 15,000 peoples
