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
Atomic radii INCREASES when going DOWN a group because of more energy levels and DECREASES going ACROSS a group because of the increasing positive charge of the nucleus pulling in on the electrons.
Answer:
30ft²
Explanation:
The area of the plywood that she has:
8 ⋅ 9
=72ft²
The area of the plywood she cut
7 ⋅ 6
=42ft²
The area discarded should be:
72ft² - 42ft²
= 30ft²
Answer: It is possible to make a valid conclusion as long as the data does not pertain to one certain region.
