15 ella made a sketch
tre
ade a sketch of an octagonal window on a 27-inch square
o paper. first, she cut 4 identical isosceles triangles from
e corners of the paper. then, she cut a square from the center
of the octagon. each leg of a cut-off triangle is the length of
the paper. the side length of the cut-out square is also į the
length of the paper. what was the area of the sketch after she
removed the triangles and the square?

r and t.

both are 64 degrees.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

126 maybe. sorry
