Given the point C on the segment AB such that the ratio of AC to CB is 3:7. Find the length of BC if the length of AB is 30 cm.
Answer: The length of BC is ...... cm
\(\frac{AC}{BC}=\frac{3}{7}\)
\(\Rightarrow\frac{BC}{AC+BC}=\frac{BC}{AB}=\frac{7}{3+7}=\frac{7}{10}\)
\(\Rightarrow BC=30.\frac{7}{10}=21\left(cm\right)\)

Given a segment AB=10cm.Let C be the point of segment AB such that AC-BC=4.Find the length of segment AC.
Answer:
AC + BC = AB = 10
AC - BC = 4
=> AC = ( 10+4)/2 = 7

The area of the dining room at thomas jefferson's home in monticello is about 342 square feet. If the approximate length of the one side is a 2-digit prime number, what are the approximate dimensions of the room?
Tham khảo
length = 19 feets and breadth = 18 feets
Given, area of the dining room = 342 square feet.
We know that, area of rectangle = length x breadth
Implies, the length and breadth are the factors of 342
Prime factorisation of 342 = 2 x 3 x 3 x 19
Given that the approximate length of one side is a prime number less than 25.
The nearest prime number less than 25 and a factor of 342 is 19.
Therefore, the approximate length of the room = 19 feet
Hence, breadth =\(\dfrac{area}{length}\)=\(\dfrac{342}{19}\)=18 feet

We have \(\Delta CAB\sim\Delta CDB\left(g.g\right)\Rightarrow\dfrac{CB}{CD}=\dfrac{CA}{CB}\) \(\Rightarrow CB^2=CD\cdot CA\) We have \(CA=CD+DA=16\left(cm\right)\) \(\Rightarrow CB^2=9\cdot16=144\Rightarrow CB=12\left(cm\right)\) We have \(\dfrac{DB}{BA}=\dfrac{CB}{CA}=\dfrac{12}{16}=\dfrac{3}{4}\) \(\Rightarrow DB=\dfrac{3}{4}AB=18\left(cm\right)\)
