A coat is reduced 30% from the orginal price of $250. what is the new price of the coat?

$175

Step-by-step explanation:

To find the new price of the coat, you simply need to multiply 250 by 0.70. This is because 30% is reduced from the original price. So, 1 - 0.30 = 0.70. After you multiply, you should get the answer 175.

250 • 0.70 = 175

no one knows lol

step-by-step explanation:

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.
