Answer: c. 150g of sugar dissolved in 300ml water
Step-by-step explanation:
The concentration of sugar syrup will decide which syrup is sweetest. Concentration is defined as the amount of solute dissolved per unit volume of solution.
a) 50g of sugar dissolved in 150ml water
b) 100g of sugar dissolved in 500ml water
c) 150g of sugar dissolved in 300ml water
d) 250g of sugar dissolved in 1000ml water
Thus 150 g of sugar dissolved in 300ml water has highest concentration and is sweetest.
Answer:
(2x - 3) * (x + 3)
=> (2x * x) + (-3 * 3)
=> 2x - 9
=> 2x -9

Answer: b. 134
Step-by-step explanation:
Given : A minimum usual value of 135.8 and a maximum usual value of 155.9.
Let x denotes a usual value.
i.e. 135.8< x < 155.9
Therefore , the interval for the usual values is [135.8, 155.9] .
If interval for any usual value is [135.8, 155.9] , then any value should lie in this otherwise we call it unusual.
Let's check all options
a. 137 ,
since 135.8< 137 < 155.9
So , it is usual.
b. 134
since 134<135.8 (Minimum value)
So , it is unusual.
c. 146
since 135.8< 146 < 155.9
So , it is usual.
d. 155
since 135.8< 1155 < 155.9
So , it is usual.
Hence, the correct answer is b. 134 .
"A. 4x^4 is the answer so try that."
