Use mental math to find the sum of 432 + 250

To start I would add 400 + 200, and that equals 600.

Then I would add 30 + 50, and that equals 80.

And then I have 2 left over.

600 + 80 = 680

Add the left over 2, so 680 + 2

680 + 2 = 682. Your answer is 682.

I hope this helps!

682

Step-by-step explanation:

Add 432+250 (4+2 is 6 3+5 is 8 2+0 is 2) put the numbers together and get 682

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
