What is the percent please help

a increase is the answer to your question

30

Step-by-step explanation:

So you would set up the equation as 50/35= 100/? Then you would solve normally so 35 times 100= 3500 then 3500/50 which is 70 but because it’s a decrease you would subtract 70 from 100. Plus if you think about it 50 percent of 50 is 25 so it wouldn’t make sense for a number greater than 25 to be over 50 percent.

translate k to n and reflect across the line containing jk.

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.
