What is the percent of change from 2000 to 200

90% decrease

Step-by-step explanation: First determine whether the number is increasing or decreasing. Since it changes from 2,000 to 200, it's going down so it's decreasing.

Now to find the percent decrease, we divide the

amount of change by the original number.

The amount of change is the difference between the two numbers

which in this case is 2,000 - 200 and the original number is 2,000.

.

2,000 - 200 is 1,800.

So we're left with 1,800/2,000 and dividing

2,000 into 1,800 gives us 0.9.

Remember however that our problem is

asking for a percent, not a decimal.

So we need to write 0.9 as a percent and we can do

that by multiplying it by 100 and adding the percent sign.

So 0.9 becomes 90%.

So when a number changes from 2,000 to 200,

it has decreased by 90%.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
