Answer: The correct answer is the one on the lower left.
Step-by-step explanation: You are looking for the equation that is five times the quotient of a number and 10.
Since it is five times the quotient, you are looking for an expression that has 5 outside of the parentheses, and a quotient means that there is division taking place. The only option that has 5 outside parentheses with division inside the parentheses is the lower left.
Answer:
![12\ ft](https://tex.z-dn.net/?f=12%5C%20ft)
Step-by-step explanation:
The question in English is
A 13-foot long staircase rests on a wall, so that the base of the staircase is separated from the wall, at floor level, at a distance of 5 feet. Calculate the height of the ladder on the wall. Remember that in a right triangle, the hypotenuse, squared, is equal to the sum of the squares on the other sides. If necessary, approach the tenth foot
Applying the Pythagoras Theorem
![13^{2} =5^{2}+h^{2}](https://tex.z-dn.net/?f=13%5E%7B2%7D%20%3D5%5E%7B2%7D%2Bh%5E%7B2%7D)
Solve for h
![h^{2}=13^{2}-5^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D13%5E%7B2%7D-5%5E%7B2%7D)
![h^{2}=144](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D144)
![h=12\ ft](https://tex.z-dn.net/?f=h%3D12%5C%20ft)
Answer:
RS = 2
Step-by-step explanation:
Points R, S, and T are collinear, and S is between R and T, in addition, RS = 2x-4, ST = 3x+2, and RT = 13. Find the value of RS
Hence:
RS + ST = RT
2x - 4 + 3x + 2 = 13
2x + 3x - 4 + 2 = 13
5x - 2 = 13
5x = 13 + 2
5x = 15
x = 15/5
x = 3
To find the value of RS
RS = 2x-4
RS = 2 × 3 - 4
RS = 6 - 4
RS = 2
