Answer:
10
4
Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
37.6 - 25.49 =
12.11
now i round
12.10
0.4 grams or 0.40 grams however you like writing decimals, but either way they are both the same.
Since it says *10^5, we must multiply the number by 100,000.
To multiply a number by 100,000, move the decimal place of the original number 5 place values to the right. Fill in any necessary zero's.
Final answer: 183,000
