Two friends, Alejandro and Mia, agreed to split the check at a restaurant. Alejandro ordered $\$12$ worth of food and Mia ordere

d $\$18$ worth. At the end of the meal, Alejandro put his $\$12$ contribution on the table, plus a $20\%$ tip on his bill and Mia put her $\$18$ contribution on the table, plus a $15\%$ tip on her bill.
The total tip left by Alejandro and Mia is equal to $r\%$ of the total check for their table, where the "total check" amount does not include the tip. What is $r$?

$r$ is 116.67 according to the information from the question above where $r$ is the percentage of tip amount to the total check amount of Alejandro and Mia. This problem can be solved by using a simple percentage formula in order to find the tip percentage. The total check amount is $30 and the total tip amount is $35, therefore the tip percentage is 116,67%=35/30*100.

In 4 ​minutes, a conveyor belt moves 800 pounds of recyclable aluminum from the delivery truck to a storage area. A smaller belt
kkurt [141]

Answer:

It takes 2 minutes 4 seconds to move the cans to storage area if both the belts are used.

Step-by-step explanation:

Given - In 4 ​minutes, a conveyor belt moves 800 pounds of recyclable

            aluminum from the delivery truck to a storage area. A smaller belt

            moves the same quantity of cans the same distance in 6 minutes.

To find - If both belts are​ used, find how long it takes to move the cans

              to the storage area.

Proof -

Given that,

Larger belt take 4 minutes to transfer the aluminium from delivery truck to storage area.

⇒ Time taken by Larger belt = 4 min/ shifting

Also,

Smaller belt take 6 minutes to transfer the aluminium from delivery truck to storage area.

⇒ Time taken by Smaller belt = 6 min/ shifting

Now,

As we know that Time is inversely proportional to time, so

Rate of Larger Belt = \frac{1}{4} shifting/min

Rate of Smaller Belt = \frac{1}{6} shifting/min

Now,

Let us assume that , if both belts used then,

Total time taken = x min/shifting

Then, Rate = \frac{1}{x} shifting/min

Now,

\frac{1}{4}  + \frac{1}{6}  = \frac{1}{x}

⇒\frac{6 + 4}{24} = \frac{1}{x}

⇒\frac{10}{24} = \frac{1}{x}

⇒10x = 24

⇒x = \frac{24}{10} = 2.4 minutes

∴ we get

It takes 2 minutes 4 seconds to move the cans to storage area if both the belts are used.
