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:
n=10
Step-by-step explanation:
5n-20=3n
-20=-2n
10=n
Answer:
2/5
Step-by-step explanation:
To find the slope of a line segment, find the difference in y and divide by the difference in x (delta y / delta x)
Delta y: -7 - (-13) = 6
Delta x: 15 - 0 = 15
Slope = delta y / delta x
Slope = 6/15 = 2/5

D = V • t ... displacement = velocity • time
d = [(s – 4) ⁄ (s² – 9s + 20)] • [(s – 5) ⁄ 4] ... rearrange terms
d = (s – 4) • (s – 5) ⁄ [4(s² – 9s + 20)] ... factor denominator
d = (s – 4) • (s – 5) ⁄ [4(s – 4) • (s – 5)]
d = ¼ mile
Answer:
The answer is 15
Step-by-step explanation:
f(x) = -4x + 3, f(-3)
f(-3) = -4x + 3
f(-3) = -4(-3) + 3
f(-3) = 12 + 3
f(-3) = 15
Thus, The answer is 15
