Estimate the sum of the following numbers: 233,189,and 402

820

Step-by-step explanation:

Here's how I estimated the numbers:

233=230

189=190

402=400

So the equation would be:

230+190+400

Which is equal to 820.

Hope this helped!

820

Explanation:

Round to the nearest multiple of 10 (ex. 180, 190, 230, 240)

233 rounds to 230, going down.

189 rounds to to 190, going up.

402 rounds to 400, going down.

230 + 190 + 400 equals 820.

The question didn't specify, and the best way to estimate more accurately is by using multiples of 10.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
