Reflex angle because straight is 180 and right is 90 and acute is less than 90
Answer:
Here is the rule: when a and b are not negative
√(ab) = √a × √b
Example: simplify √8
√8 = √(4×2) = √4 × √2 = 2√2
(Because the square root of 4 is 2)
In other words 2 x 4 = 8 = √2 x 4 but 4 can be simplified more (2 x 2) so 2 (previous 4) moves to the left of the square root leaving 2√2
To simplify a square root: make the number inside the square root as small as possible (but still a whole number)
or you can use a simplifying square root calculator.
|2x-3|=2x-1
need to consider two cases
(1) 2x-3<0 --> x<3/2
-(2x-3)=2x-1
x=1, and this is <3/2 so that's a valid solution
(2) 2x-3>=0 --> x>=3/2
2x-3=2x-1
-3 = -1 so there no solution for x>=3/2
The single solution is x=-1
1kg=1,000g
300/1,000=3/10
3/10=0.3
2+0.3=2.3
2 3/10kg in fractions.
2.3kg in decimals.
Well, the largest set it belongs to is the set of all real numbers - numbers which can be written on the number line. -5 is of the set of rational numbers since it can be written as a fraction (-5/1 for example). It is an integer since it is a whole number. Thus:
-5 ∈ <span> ℤ (</span>Integers) ∈ ℚ (Rational Numbers) ∈ <span>ℝ (Real Numbers)</span>
