Answer:
30m
Step-by-step explanation:
Here is the complete question
A tree is standing behind a building. 2/5th of the height of the tree can be seen and the rest is hidden by the building. The building is 12 metres high. What is the height of the tree?
If 2/5 of the tree can be seen the tree covers ( 1 - 2/5) 3/5 of the tree. If the building is 12 metres high, it means that 2/5 of the building is 12m high
the height of the tree = 12 x (5/2) = 30m
If you take 11/5 you get 2.2
Answers: 11-20
Step-by-step explanation: Step 1. Flip the equation Step 2. Add the number to both sides Step 3. Divide both sides by the number to get your answer.
1. v=10 2. m=7 3. r=-9 4. k=9 5. r=0 6. x=10 7. x=6 8. 9=3 9. m=-10 10. n=-10
11.p=0
12.x=10
13.b=4
14.n=0
15.p=2
16.x=8
17.m=8
18.x=3
19.n=-1
20.n=9
Answer:2x^2-√(3)
Step-by-step explanation:
Sign change in the conjugate
Therefore we have 2x^2-√(3)
