A football team has a squad of 24 players,
lora16 [44]
Answer: 1/3

Explanation:

1/12 of the squad are suspended:

1/12 x 24 = 24/12 = 2

So 2 player are suspended

24 - 2 = 22 player

And some are injured leaving 14 left to play:

22 - 14 = 8 players injured

So 8/24 is the fraction of injured player.

But 8/24 = 1/3 so we can say 1/3 of the whole squad are injured.

xenn [34]

Answer:

Option d. 1 in: 12 ft.

Step-by-step explanation:

A scale model of building is 2 inches tall. If the building is 24 feet tall then we have to find the scale of the model.

Since scale of the model is represented by the ratio of size of scale model and size of original building

Scale factor=\frac{\text{Height of scale}}{\text{Height of building}}

                          = \frac{2}{24}

                          =  \frac{1}{12}

Therefore, Scale of the model is 1 inch : 12 ft.
