16 because 8 rooms have 8-11, 5 rooms have 4-7, and 3 rooms have 0-3 guests.
Ivan3 years ago
3 0

Answer:

13

Step-by-step explanation:

Because the question asks for the number of hostel rooms with 11 or less guests, we will add the amounts from the three categories that meet this requirement. Lets find the number of rooms for each:

0 - 3 guests: 3 rooms

4 - 7 guests: 5 rooms

8 - 11 guests: 8 rooms

Now, we will add 3, 5 and 8.

3 + 5 + 8 = 16

This means thirteen hostel rooms have 11 of fewer guests.

A rectangle is 5 meters longer than its width. If the length is shortened by 2 meters and width is increased by 1 meter, the are
Katarina [22]

Answer: Area = 6m²

              Smaller number = 16

              Hours = 9.6 h

Step-by-step explanation:

A rectangle is 5 meters longer than its width. If the length is shortened by 2 meters and width is increased by 1 meter, the area remains the same. Find the area of the rectangle.

1) w = x m                                2) w = x + 1 m

     l = x + 5  m                               l = x + 5 - 2 = x + 3 m

A₁ = A₂

A = w*l

A₁ = x(x+5) = x² + 5x

A₂ = (x+1)(x+2) = x² + x + 2x + 2 = x² + 3x + 2

A₁ = A₂

x² + 5x = x² + 3x + 2

5x - 3x = 2

2x = 2

x = 1

A₁ = x(x+5) = 1.6 = 6 m²

The ratio of two numbers is 2:5. If the larger number is 40, what is the smaller number.

<u> 2 </u> = <u> x </u>

5     40

5x = 80

x = 80/5 = 16

Sixteen construction workers can finish cementing a floor of a building in 3 hours. On a certain day, only 5 construction workers are available for the job. How long will it take the 5 construction workers to do the cementing job?

5x = 16*3

5x = 48

x = 48/5
