3/2 I'm pretty sure idk if I'm right though but you'll do good!
Answer:
A) 6.86×10⁴
Step-by-step explanation:
You want to write 68600 in scientific notation.
<h3>Expanded form</h3>
The number 68600 can be written in expanded form with exponents as ...
68600 = 6×10⁴ +8×10³ +6×10² +0×10¹ +0×10⁰
The left-most term of this sum tells you the exponent in scientific notation:
68600 = 6.86×10⁴

Answer:
we have 448 ways of putting them.
Step-by-step explanation:
For the first piece we have no restrictions, so we have 8*8 = 64 ways of puting it. For the second piece we have 7 ways to put it in the same row and 7 ways of put it in the same column, so we have 14 ways.
This gives us a total of 14*64 = 896 ways.
However, since the pieces are indistinguishable, we need to divide the result by two, because we were counting each possibility twice, (if we swap the pieces, then it counts as the same way), thus we have 896/2 = 448 of putting two pieces on the board.
<u><em>Answers:</em></u>
(i) Length = 82 m
(ii) Area = 3,444 m²
<u><em>Explanation:</em></u>
<u>1- getting the length of the plot:</u>
<u>The perimeter of a rectangle is calculated as follows:</u>
Perimeter = 2(length + breadth)
We are given that the perimeter is 248 m and that the breadth is 42 m
<u>Substitute with the givens in the above equation to get the length as follows:</u>
Perimeter = 2(length + breadth)
248 = 2(length + 42)
length + 42 = 248/2
length + 42 = 124
length = 124 - 42
length = 82 m
<u>2- getting the area:</u>
<u>The area of a rectangle is calculated as follows:</u>
Area = length * breadth
We have the length = 82 m and the breadth = 42 m
<u>Therefore:</u>
Area = length * breadth
Area = 82 * 42
Area = 3,444 m²
Hope this helps :)
