Write as a numeral: 7 × 10 + 2 + ( 7 × 1⁄10 ) + ( 2 × 1⁄100 )

3042

Step-by-step explanation:70+2+770+2200=3042

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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.
