Tin of biscuits come in three sizes. There are 28 biscuits in a small size and four times as many in the medium size. In the large size there are seven times as many as in small size how many biscuits are in the small and large size

There are 28 biscuits in a small size.

There are 112 biscuits in a medium size.

There are 196 biscuits in a large size.

Step-by-step explanation:

Tin of biscuits come in three sizes:

Let S denote biscuits in small size.

Let M denote biscuits in medium size.

Let L denote biscuits in large size.

There are 28 biscuits in a small size and four times as many in the medium size.

Mathematically,

S = 28

M = 4S

Substitute S = 28

M = 4(28)

M = 112

In the large size there are seven times as many as in small size.

L = 7S

Substitute S = 28

L = 7(28)

L = 196

Therefore,

There are 28 biscuits in a small size.

There are 112 biscuits in a medium size.

There are 196 biscuits in a large size.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
