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

(CO 2) A random selection from a deck of cards selects one card. What is the probability of selecting a spade

lora16 [44]

Answer:

$P(Spade) = 0.25$

Step-by-step explanation:

Given.

In a deck, there are:

$Cards = 52$

$Spade= 13$

Required

Determine the probability that a selected card is a spade

This is represented as: P(Spade) and it is calculated using:

$P(Spade) = \frac{Spade}{Cards}$

Substitute 13 for Spade and 52 for Cards

$P(Spade) = \frac{13}{52}$

$P(Spade) = 0.25$

Hence, the required probability is 0.25
