Answer: 132
Step-by-step explanation: For day A the students payed 40 dollars and on day B they paid 92 so 40+92=$132 in all.
300,000,000+010,000,000+9,000,000+700,000+60,000+3,000+100+60+3
Answer:
The actual height of telescope is 42.85 inches
Step-by-step explanation:
Given that:
Height of model of telescope = 15 inches
Diameter of model of telescope = 3.5 inches
Actual diameter of telescope = 10 inches
Actual height of telescope = x
Ratio of model's diameter to height :: Ratio of actual diameter to height
3.5 : 15 :: 10 : x
Product of extreme = Product of mean
3.5*x = 10*15
3.5x=150
Dividing both sides by 3.5
![\frac{3.5x}{3.5}=\frac{150}{3.5}\\x=42.85](https://tex.z-dn.net/?f=%5Cfrac%7B3.5x%7D%7B3.5%7D%3D%5Cfrac%7B150%7D%7B3.5%7D%5C%5Cx%3D42.85)
Hence,
The actual height of telescope is 42.85 inches
1. < DCE=< DEC in the picture
⇒<ABC=<DEC=< DCE=<BCA ⇒ the triangle ABC is isosceles
2. ⇒<GFE=<DCE=<DEC=<FEG ⇒ the triangle EFG is isosceles
⇒ the triangles ABC and EFG have 2 angles equals ⇒ ABC~ EFG
5. ⇒ < ABC=<GEF =<DEC= < DCE=< BCA ⇒ the triangle ABC is isosceles
6. < GFE = < BCA= < ECD = <DEC = <FEG ⇒ the triangle EFG is isosceles
⇒ the triangles ABC and EFG have 2 angles equals ⇒ ABC~ EFG
