sdas [7]

Answer:

£95

Step-by-step explanation:

Cost of 11 cushions = £55

Unit cost of 1 cushion = 55/11 = £5 per cushion

Cost of buying 19 cushion = 19 × unit cost

= £95

Thus, it would cost £95 to buy 19 cushions

Which pair of measurements is not equivalent? 6,000 mL, 6 L 9500 mL, 9.5 L 4.5 L, 450 mL 0.3 L, 300 mL

dalvyx [7]

4.5l and 450ml are the pair of measurements which is not equivalent

Solution:

Let us solve each pair of measurements to find which is not equivalent

first pair: 6000 ml and 6 L

To compare both quantities, they must be in same units. Let us convert them into same units

we know that 1 liter = 1000 milliliter

Hence 6 liter = 6000 milliliter

Hence both are equivalent. This pair is correct

Second pair: 9500 ml and 9.5L

$9.5L = 9.5 \times 1000 = 9500ml$

Hence both are equivalent. This pair is correct

Third pair: 4.5L and 450 ml

$4.5l = 4.5 \times 1000 = 4500 ml$

Both are not equivalent

Fourth pair: 0.3 L and 300ml

$0.3l = 0.3 \times 1000 = 300ml$

Hence both are equivalent. This pair is correct

Thus 4.5l and 450ml are not equivalent
