Answer:
The answer to your question is 12 ft
Step-by-step explanation:
Data
Height of the flag pole = 24
shadow of the flag pole = x
height of the man = 5 ft
shadow of the man = 2.5 ft
Process
1.- Use the Thales' theorem to solve this problem
shadow of the flag pole/height of the flag pole = shadow of the man/height
of the man
- Substitution
x/24 = 2.5/5
- Solve for x
x = 2.5(24)/5
- Simplification
x = 60/5
-Result
x = 12 ft
Answer:
SA = 384 in ^2
Step-by-step explanation:
The surface area of a cube is given by
SA = 6 S ^2 where s is the side length
SA = 6 * (8) ^2
SA = 6 * 64
SA = 384 in ^2
Answer:
Step-by-step explanation:
5 * 45 = 225
5 * 70 = 350
Answer:A is the correct answer
Step-by-step explanation:
Let x represent the number of female students that are left handed. There are 5 times as many right handed female students as there are left handed female students. This means that the number of female students that are right handed is 5x
Let y represent the number of male students that are left handed. There are 9 times as many right handed male students as there are left handed male students. This means that the number of male students that are right handed is 9x
The total number of left handed students is 18. Therefore
x + y = 18
The total number of right handed students is 122. Therefore
5x + 9y = 122 - - - - - - - - - -1
Substituting x = 18 - y into equation 1, it becomes
5(18 - y) + 9y = 122
90 - 5y + 9y = 122
- 5y + 9y = 122 - 90
4y = 32
y = 32/4 = 8
x = 18 - y = 18 - 8
x = 10
Total number of right handed female students is 5×10 = 50
Total number of right handed students is 122.
Probability that a right handed student selected at random is a female will be
50/122 = 0.4098
approximately 0.410
