Here are two offers for batteries.
trapecia [35]

OFFER A is cheaper.

Step-by-step explanation:

Given,

OFFER A

Pack of 5

£2.75

Pay for 3 packs get 1 free

And

OFFER A

Pack of 5

£2.75

Pay for 3 packs get 1 free

To find which offer is cheaper.

<u>For OFFER A</u>

For 4 Packets he needs to pay £2.75

He needs to buy 40 batteries.

He needs to buy 40÷(4×5) = 2 packets.

Total cost = £2.75 ×2 = £5.5

<u>For OFFER B</u>

For 4 Packets he needs to pay £2.52

He needs to buy 40 batteries.

He needs to buy 10 packets.

After discount he has to pay = £2.52 -(£2.52 ×\frac{1}{3}) = £1.68

Total cost = £1.68×10 = £16.8

Hence,

OFFER A is cheaper.

Which of the following sets of numbers could not represent the three sides of a triangle?
timama [110]

Answer:

  (c)  {13,16,30}

Step-by-step explanation:

In order for the sides lengths to form a triangle, the sum of the shortest two must exceed the longest.

That will not be the case for ...

  {13, 16, 30}

because 13 +16 = 29 < 30.

  (13, 16, 30} could not form a triangle
