Answer:

The total number of students that ate lunch are 300 .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.

The percentage of students that chose salad is 15%.

If 45 students chose salad.

Here

Percentage = 15%

Part value = 45

Put in the formula

15 = \frac{45\times 100}{Total\ value}

Total\ value= \frac{4500}{15}

Total\ value= 300

Therefore  the total number of students that ate lunch are 300 .

if each side of a square classroom is 25 feet then what is the perimeter of the room? what is the area of the floor of the room?
Svetllana [295]

Answer:

P = 100

Area = 625

Step-by-step explanation:

Area = s^2

sqrt(area) =  sqrt(s^2)

area = 25*25

sqrt(25*25) = sqrt(s^2)

s = 25

P = 4*s

P = 4 * 25

P = 100

Area = s^2

s = 25

Area = 25^2

Area = 625
