You put 45 first then 275 and divide them and you get 0.1636363636
Well, you know in math, if you say "what is this number of this number?" It always means you multiply those two numbers. So 2/3 of 2 cups would be saying the same if I said 2/3 cups times 2 cups. Anyways, the answer would be 1.3 with a bar notation over the 3.
This is a geometric sequence of the form:
a(n)=ar^n, a=initial value, r=common ration, n=term number, if we relabel it for h(b) we have
h(b)=14(0.8^b)
h(3)=14(0.8^3)
h(3)≈7.2 ft (to nearest tenth of a foot)
25 degrees
15-25=-10
-10+25=15
