The highest yielding savings accounts are paying historically low interest rates, so Maria is only able to get a 1% annual interest rate for her savings account. Assuming interest rates do not change, use the Rule of 72 to approximate how many years it will take for her to DOUBLE her money in this account? 10

what is the original number? you forgot to add it.

b. x + 1

step-by-step explanation:

i'am smart

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
