Y varíes directly as x. Y=112 when x=8. Find y when x=13

Mathematics
1 answer:
Alinara [238K]4 years ago
5 0

Answer:

y = 182

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 112 when x = 8

k = \frac{y}{x} = \frac{112}{8} = 14

y = 14x ← equation of variation

When x = 13, then

y = 14 × 13 = 182

You buy the following materials for the new extension.
Daniel [21]

I assume you mean

2 tonnes of sand at £75.00 per tonne

20 bags of cement at £6.70 per bag

350 bricks at 45p each

If so, then

2 tonnes of sand at £75.00 per tonne = 2 * £75.00 = £150.00

20 bags of cement at £6.70 per bag = 20 * £6.70 = £134.00

350 bricks at 45p each = 350 * £0.45 = £157.50

Add the three amounts

£150.00 + £134.00 + £157.50 = £441.50

Answer: 441.50
