Answer:
A.
4Fe + 3O2 2Fe2O3 .........................
Answer:
54
Explanation:
First write the list of numbers which the tens number is one less then ones place.(21,32,43,54,65,76,87,98). Remember this list then add the digits together. If you know your multiplication, the first 5 should be easy to solve so multiple the sum you received from adding the numbers by 6 until you get to one with the same starting number
(21)2+1= 3 x 6= 18
(32)3+2= 5 x 6= 30
(43)4+3= 7 x 6= 42
(54)5+4= 9 x 6= 54
(65)6+5=11
(76)7+6=13
(87)8+7= 15
(98)9+8 = 17
Answer:
6m ramp
Explanation:
I'm assuming you need the ramp which will make it the easiest which would be the 6m ramp because since it is longer it will be a more gradual incline making it easier to move the boxes.
