Answer:
The green one
Step-by-step explanation:
In an obtuse triangle, one of the angles is greater than 90 degrees.
Answer:
Yes
Step-by-step explanation:
When the greatest common factor of two numbers is 1 or -1, the numbers are known as relatively prime. This means there are no numbers that can be factored out of both of the numbers, meaning if the numerator and denominator are relatively prime, they can not be simplified any further.
Answer:
6 fingers
Step-by-step explanation:
Let X = the base of the numbers above
If X > 0
Then we have:
325 = 3 * X² + 2 * X¹ + 5 * X°
325 = 3X² + 2X + 5
42 = 4*X¹ + 2*X°
42 = 4X+ 2
And
411 = 4*X²+ 1*X¹ 1*X°
42 = 4X² + X + 1
Since 325 + 42= 11 then
3X² + 2X + 5 + 4X+ 2 = 4X² + X + 1 ------ Collect Like Terms
3X² - 4X² + 2X + 4X - X + 5 + 2 - 1 = 0
-X² + 5X + 6 = 0 ------- Multiply both sides by -1
X² - 5X - 6 = 0 ------- Factorise the Equation
X² - 6X + X - 6 = 0
X(X - 6) + 1( X - 6) = 0
(X + 1)(X - 6) = 0
X + 1 = 0 or X - 6 = 0
X = -1 or X = 6
But X>0
So, X =-1 is invalid
X = 6
The expected number of fingers of the Martian is 6

-- "Two hundred and three thousandths"
means' ' 2.003 '.
-- "Two hundred three thousandths" would mean ' 0.203 '.
How can you tell the difference?
The difference is the 'and'.</span> "And" means 'decimal point'.
' 678 ' is read as "six hundred seventy eight", with no 'and'.
' 40.06 ' is read as 'forty and six hundredths'.
' 0.46 ' is read as ' forty-six hundredths'.
