8-8^-1
=8-1/8 <<< 8*8=64 then 64-1=63
=63/8
in decimal(7.875)
Start at -4 on the number line. Move 6 units to the left to get to -10
This shows -4 - 6 = -10
8.5 x 250,000 = 2,125,000
2,125,000 x .00001 = 21.25km
1cm = .00001km
Answer:
The total employee of the company is 11912
Step-by-step explanation:
The employee in one country = 27,100
Let the total population be P

P = 11912 (approximately)
So the total employee of the company is 11912
Answer:
8m ×3.5m
Step-by-step explanation:
Area of rectangle= length ×width
Let the length and width of the rectangle be L and W meters respectively.
Area of rectangle= LW
LW= 28 -----(1)
L= 2W +1 -----(2)
Subst. (2) into (1):
(2W +1)(W)= 28
<em>Expand:</em>
2W² +W= 28
<em>-28 on both sides:</em>
2W² +W -28= 0
<em>Factorise</em><em>:</em>
(W +4)(2W -7)= 0
W +4=0 or 2W -7=0
W= -4 (reject) or W= 3.5
Substitute W= 3.5 into (2):
L= 2(3.5) +1
L= 7 +1
L= 8
∴ The dimensions of the rectangle is 8m ×3.5m.
