Explanation for Question 14 From the Math (Calc) Section on the 2018 May Sat
Question 14 says assuming good growing conditions. 2 How many years old is a giant Sequoia tree with a trunk diameter of 3 19 feet. So all we have to do here is take 19 feet, 4 convert that into inches, and then plug that into the equation we found last 5 time, which is Y is equal to two X. 6 So to convert this to inches, I'm going to multiply it by 12, 7 which gives me 228. 8 And then I'm going to plug that in for Y so 228 is equal 9 to two X I'll divide, both sides by two. 10 And that tells me that X is equal to one 14. 11 And that's C is the correct.
