Answer:

564 tiles

Step-by-step explanation:

there are many ways to solve this soo...

1. convert to centimetres (there are 100 centimetres in 1 metre)

2. the square tiles area = 20*20=400cm

2. find the large area (4.8m x 3.8m or 480cm x 380cm)

480 *380=182400cm

2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)

2(120*180)=4.3200cm

3. add to find total area

182400 +43200=225600cm

4. find how many tiles are needed

\frac{225600}{400}= 564 tiles

19. Luggage on a certain airline is limited to 2 pieces per person.
Mama L [17]

Answer: The second piece can weigh 256 pounds at most.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

The sum of the weight of each piece of Luggage must be less or equal to 581 pounds:

x + 325 ≤581

Where x is the second piece's weight.

Solving for x:

x ≤581 -325

x ≤ 256

The second piece can weigh 256 pounds at most.

Feel free to ask for more if needed or if you did not understand something.

Gias gross annual salary is 46,392. what is the recommended maximum monthly rent she should pay?
jeyben [28]
The maximum monthly rent that she should pay is 2,784.
Solution:
1,082 x 12 months = 12,984
1,648 x 12 months = 19,776
1,933 x 12 months = 23,196
2,784 x 12 months = 33,408

Since her annual salary is 46,392, she can still afford to pay the rent for 2,784 per month, which equals to 33,408 annually.
