80 since he starts off with 38 stamps then gains 6 each month for 7 months (6x7=42) so 42+38=80
Answer:
The answer to your question is 55 ft
Step-by-step explanation:
Data
Person's height = 5 ft
Person's shadow = 10 ft
Tree's height = ?
Tree's shadow = 110 ft
- Use the Thales' theorem to solve this problem
Person's height / Person's shadow = Tree's height / Tree's shadow
- Substitution
5 / 10 = x / 110
-Solve for x
x = 5 (110) / 10
-Simplification
x = 550 / 10
-Result
x = 55 ft
-Conclusion
The tree is 55 ft height
Since there is a right angle, you can use Pythagoras' Theorem:
So x = √(24² + 7²) = 25

Answer:
25
You would do 20-6 which = 14. + 1 =15. times 8= 120 then divide that by 1/2 = 240 if you do 120 divided by .5 in a calculator thats what you get. i hope that helps you
The sum of two numbers will be zero when you have the same number and one is positive and one is negative. For example 1 + -1= 0
