Step-by-step explanation:
If 1 lunch =$2.50
2 lunches = $5.00 (2.50x2)
3 lunches =$7.50
4 lunches =$10.00
5 lunches= $12.50
basically just add $2.50
Using the multiplication principle, the completed table is shown below :
Quantity ___ cost 1 _________ 2.502 ________ 5.003 ________ 7.504 ________ 10.00The total cost for any quantity given can be obtained by taking the product of the quantity and the cost per lunch ;
Hence, the cost of quantities 1, 2, 3, and 4 are $2.50, $5.00, $7.50 and $10.00 respectively.

So the area would be 3 times the area of the cafeteria.

Answer:
Step-by-step explanation:
I'm not sure but it might be because, while not in a vapor state yet, the molecules are moving faster as they get hotter and are getting closer to being a gas. Because they aren't vibrating in place anymore, they will need more room to more around. Again, I'm not positive but I think that this might work.

The sum of 3 terms in A. P.is - 3 and their product is 8, then sum of squares of the numbers is
sum of the numbers = - 3
Product of the numbers = 8
Find:sum of squares of the numbers
Solution:Let the three terms be a - d , a , a + d.
sum of the numbers = - 3
→ a - d + a + a + d = - 3
→ 3a = - 3
→ a = - 3/3
→ a = - 1
Also,
Product of the numbers = 8
→ (a - d) * (a) * (a + d) = 8
Putting the value of a and using (a + b) * (a - b) = a² - b² we get,
→ [ (- 1)² - d² ] = 8/ - 1
→ 1 - d² = - 8
→ 1 + 8 = d²
→ 9 = d²
→ d = 3
Hence,
a - d = - 1 - 3 = - 4 a = - 1 a + d = - 1 + 3 = 2Now,
Finding Sum of their squares :
→ (a - d)² + a² + (a + d)²
→ ( - 4)² + ( - 1)² + (2)²
→ 16 + 1 + 4
→ 21
Hence, the sum of the squares of the three terms is 21.
I hope it will help you.

Se midió la longitud de un segmento con una regla que tiene la graduación hasta un milímetro y se obtuvo la medida 5.3 cm. ¿Entre qué valores está la medida real x cm? Expresa tu respuesta con una desigualdad.
Answer:
Las siguientes desigualdades expresan la condición real de la medida:
[tex]5.2\,cm < x <5.4\,cm[/tex], donde [tex]x[/tex] es la medida captada visualmente.
O de manera más rigurosa:
[tex]5.2\,cm \leq (5.3 \pm \epsilon)\,cm\leq 5.4\,cm[/tex], donde [tex]\epsilon[/tex] es el sesgo no captado por el observador.
Step-by-step explanation:
La graduación de la regla es la resolución visual de la medida, equivalente a 0.1 centímetros. Entonces, la medida obtenida de 5.3 centímetros es equivalente a un valor [tex]x[/tex] mayor que 5.2 centímetros y menor que 5.4 centímetros. Matemáticamente hablando, tenemos la siguiente desigualdad:
[tex]5.2\,cm < x <5.4\,cm[/tex], donde [tex]x[/tex] es la medida captada visualmente.
De manera más rigurosa, podemos describir el valor medido más un sesgo no captado por el observador ([tex]\epsilon[/tex]), medido en centímetros, dentro del intervalo citado:
[tex]5.2\,cm \leq (5.3 \pm \epsilon)\,cm\leq 5.4\,cm[/tex]

Answer:
DeMarcus will pay $18.38. His tip is $3.06.
Step-by-step explanation:
Change the percent into a decimal: 20% = 0.20
Multiply the decimal by $15.32: 0.20 x 15.32 = $3.06
Add the tip to the total: 15.32 + 3.06 = $18.38
Layla loves to try out new bike trails in her area. Last week, it took her 24 minutes to ride a trail that is 6 miles long. Today, she kept the same pace when she rode an 8-mile trail. How long did it take Layla to ride the trail today?
Answer:
32
Step-by-step explanation:
You have divided 24 and 6 to get 4
Then 8 - 6 is 2
2 x 4 is 8
and last 24 + 8 = 32
Hope this helped don't forget to mark brainliest☺️
Layla takes 32 minutes to ride 8-mile long trail.
Given Last week, Layla took 24 minutes to ride a trail that is 6 miles long.
So Speed of Layla to cover 6 miles is , [tex]\frac{6}{24} =0.25[/tex] miles per minute.
Now, Layla kept same speed of 0.25 miles per minute to rode 8-mile trail.
So, Time taken by Layla to cover 8 miles is [tex]\frac{distance}{speed}[/tex][tex]=\frac{8}{0.25} = 32[/tex] minutes.
Hence Layla takes 32 minutes to ride 8-mile long trail.

You are making a banner from a piece of paper that is 11/12 feet long. You cut off a piece that is 1/4 feet long. How much paper is left to make the banner?
Answer:
2/3 feet
Step-by-step explanation:
Available length = 11/12 feet
Piece cut out = 1/4 feet
How much paper is left to make the banner?
Paper remaining = available length - piece cut out
= 11/12 - 1/4
= 11-3 /12
= 8/12
= 2/3 feet
Paper left to make the banner = 2/3 feet
