A shop sells orange juice in the following ways:

ICE Princess25 [194]

Answer:

The cheapest way to purchase 9 liters of orange juice would be to buy 3 promotions of 2 1.5 liter bottles of drink at £ 5 each promotion, totaling £ 15.

Step-by-step explanation:

To obtain the cheapest way to buy 9 liters of orange juice, the cost per liter of each type of container must be determined:

500 ml bottle = £1.15 (£2.30 per liter)

1.5 l carton = £2.70 (£1.80 per liter)

2 cartons of 1.5 l = £5 (£1.66 per liter)

3.5 l carton = £5.75 (£1.64 per liter)

Thus, there is in principle a staggered way to buy the drink: 2 cartons of 3.5 liters, plus 1 carton of 1.5 liters, plus 1 bottle of 500 ml, which would add up to a total cost of £15.35 (5.75 x 2 + 2.70 + 1.15) .

Now, you could also take advantage of the promotion of 2 cartons of 1.5 l at £5, with which buying 3 of these promotions would acquire the 9 liters of drink (1.5 x 2 x 3) at £15 (3 x 5).

Thus, the cheapest way to purchase 9 liters of orange juice would be to buy 3 promotions of 2 1.5 liter bottles of drink at £ 5 each promotion, totaling £ 15.

Which ordered pairs are in the solution set of the system of linear inequalities?

Elanso [62]

Answer:

The ordered pairs (5 , -2) , (3 , 1) , (4 , 2) are in the set of the solution ⇒

3rd answer

Step-by-step explanation:

- The first line has negative slope and passing through points (0 , 0)

and (4 , -2)

∵ $y>\frac{-1}{2}x$

- The second line has positive slope and passing through points (-2 , 0)

and (2 , 2)

∵ $y$

- Look to the attached figure to see the common part of the solutions

- The red shaded represents the inequality $y>\frac{-1}{2}x$

- The blue shaded represents the inequality $y$

- The shaded part with two colors represents the common solutions

of the two inequalities

- Lets find the ordered pairs which are in the solution set of the system

of linear inequalities

- Points (-4 , 2) , (-3 , 1) , (4 , -3) lies out the common shaded

- Points (5 , -2) , (3 , 1) , (3 , -1) , (4 , 2)

∵ Point (5 , -2) lies in the common shaded part

∵ Point (3 , 1) lies in the common shaded part

∵ Point (4 , 2) lies in the common shaded part

∴ The ordered pairs (5 , -2) , (3 , 1) , (4 , 2) are in the set of the

solution

Elle placed a bucket under a leaky roof. The bucket was 310 full after 25 of an hour. How much water is leaking per hour?

kvasek [131]

Answer:

3/4 bucket

Step-by-step explanation:

Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour

Water leaking : time taken

Let x = amount of water leaking per hour

3/10 : 2/5 = x : 1

3/10 ÷ 2/5 = x / 1

3/10 × 5/2 = x / 1

15 / 20 = x / 1

Cross product

15 * 1 = 20 * x

15 = 20x

x = 15/20

= 3/4

3/4 bucket of water is leaking per hour
