15 acres decreased by 80% =

Hi there! Hopefully this helps!

First, you have to find what 80% of 15 is.

In order to do that, you have to change 80% percent to decimal.

80% to a decimal is 0.80.

Then, multiply .80 and 15 to get 12.

Subtract 12 from 15, and your answer is 3.

i think 1: 2

step-by-step explanation:

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.
