How is a rhombus related to a parallelogram? How does finding the area of a rhombus compare to finding the area of a parallelogram? A: A rhombus is a parallelogram with equal sides.

B: The area of a rhombus is found using the formula A = b x h.

C: The area of a rhombus is less than the area of a parallelogram with equal dimensions.

D: A parallelogram is always a rhombus.

E: The area is found the same way for both a rhombus and a parallelogram.

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

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.
