Answer:
The answer is approximately 24.041 inches (round to the nearest tenth, hundredth, or thousandth if it is indicated in the instructions.)
Step-by-step explanation:
First, I figured out what the square root of 289 is. The square root of 289 is 17.
Given that this is a square we are dealing with, we can assume that all sides are equal.
So, when you draw a diagonal down the square, it becomes two triangles, one of which we can use the Pythagorean theorem for.
a^2 + b^2 = c^2. Thus, 17^2 + 17^2 = 578. The square root of 578 unfortunately does not come out evenly, so we are left with approximately 24.041 inches.
I hope this helps!
Answer:
n = 24
Step-by-step explanation:
From the question,
The formula for the sum of the term in an AP is given as
Sₙ = n(a+L)/2.................. Equation 1
Where Sₙ = sum of the nth term, n = number of term, a = first term, L = last term.
make n the subject of the equation
n = 2Sₙ/(a+L)................. Equation 2
Given: Sₙ = 420, a = 4, L = 31
Substitute these values into equation 2
n = (2×420)/(4+31)
n = (840)/35
n = 24.
Hence, n = 24
