Midge arranges her Collection of 762 seashells and two trays with eight shells in each tray Find the number of trays she needs

The number of trays she needs is 94 trays.

Step-by-step explanation:

Total seashells = 762.Number of trays she already has = 2 trays.Number of seashells in each tray = 8 seashells.  

Number of trays she needs :

Number of seashells already arranged = 28 = 16 seashells.Remaining seashells = 762 - 16 = 746 seashells.

Number of trays needed = Remaining seashells / 8

⇒ 746/8

⇒ 93 trays and remaining 2 seashells is arranged in another tray

⇒ 93+1 = 94 trays.

Given:

Consider the below table attached with this question.

Every square meter of ceiling requires 10.75 tiles.

To find:

The missing values in the table.

Solution:

We have,

1 square meter of ceiling =  10.75 tiles.      ...(i)

Therefore, the number of tiles corresponding to 1 square meter of ceiling is 10.75.

Multiply both sides by 10.

10×1 square meter of ceiling =  10×10.75 tiles.

10 square meter of ceiling =  107.5 tiles.

Therefore, the number of tiles corresponding to 10 square meter of ceiling is 107.5.

Divide both sides by 10.75 in (i).

square meter of ceiling = 1 tile.

Multiply both sides by 100.

square meter of ceiling = 100 tiles.

On approximating the value, we get

9.3 square meter of ceiling = 100 tiles.

Therefore, the square meters of ceiling corresponding to 100 tiles is about 9.3.

Multiply both sides by a in (i).

a×1 square meter of ceiling =  a×10.75 tiles.

a square meter of ceiling =  10.75a tiles.

Therefore, the number of tiles corresponding to a square meter of ceiling is 10.75a.
