A clothes shop has some special offers. T-shirts are buy one get one free and jumpers are 3 for 2. The normal price of a T-shirt is £4.80 and the normal price of a jumper is £14.60. How much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate? £

£53.40

Step-by-step explanation:

The shop has an offer where you:

buy 1 T-shirt and get 1 free

buy 3 jumpers and get 2 free

This means if a person pays for 1 T-shirt, he/she gets two and if he/she pays for 3 jumpers, he/she gets 5.

Therefore, to buy 4 T-shirt, you have to pay for 2 and to buy 5 jumpers, you have to pay for 3.

1 T- shirt costs £4.80, therefore, 2 will cost:

2 * 4.80 = £9.60

1 jumper costs  £14.60, therefore, 3 will cost:

3 * 14.60 = £43.80

Therefore, the customer will sped a total of:

43.80 + 9.60 = £53.40

The customer will pay £53.40 to get 5 jumpers and 4 T-shirts using this offer.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
