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
Answer:
x = 2.95
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
0.45 plus 9x equals 27
0.45 + 9x = 27
<u>Step 2: Solve for x</u>
0.45 + 9x - 0.45 = 27 - 0.45
9x / 9 = 26.55 / 9
x = 2.95
Answer: x = 2.95
Answer:
All numbers greater than -16.
Step-by-step explanation:
Hello!
To keep this expression negative, we can subtract a positive number (numbers greater than or equal to 0), to give us an even smaller negative number.
Another option is to add a negative number so that the value is still negative. We can add any number that is larger than -16.
Answer: All numbers greater than -16
Answer:f(3) = 23
Step-by-step explanation:
2(3)² + 5√(3 - 2)
f(3) = 2(9) + 5√(1)
f(3) = 18 + 5(1)
f(3) = 18 + 5
f(3) = 23
