how many times larger is the mass of an average grain of rock song than the mass of an average grain of table salt​

Answers

Answer:

40

Step-by-step explanation:

The sample answer for edmentum is: The first factor of the mass of an average grain of rock salt is 40 times the first factor of the mass of an average grain of table salt. So, the mass of an average grain of rock salt is 40 times greater than the mass of an average grain of table salt.

The mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt

What is scale factor?

Scale factor is used to compare the size of two objects. Mathematically, we can write -

{K} = S{O1}/S{O2}

13 mg

Given is to compare the mass of an average grain of rock sand than the mass of an average grain of table salt​.

The mass of an average grain of rock sand is : 13 mg

The mass of an average grain of table salt is : 0.3 mg

So, we can write that -

{K} = M{rock sand}/M{table salt}

{K} = 13/0.3

{K} = 130/3

{K} = 43.4

So, it can be concluded that the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Therefore, the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Luca is planning to pay the restaurant bill for his coworkers. The bill was $193.75. A 4% tax was then added by the waiter. If Luca wants to leave a 16% tip on the total amount including the tax, how much should Luca pay?
$201.50
$217.50
$224.75
$233.74? pls help 50 point give good ansewr

Answers

Answer:

D; $223.74

Step-by-step explanation:

The amount of bill before tax = $193.75

Percentage of tax added by the waiter = 4%

Amount of tax added by the waiter = (4/100) * 193.75 dollars

                                                       = 775/100 dollars

                                                       = 7.75 dollars

Total bill after tax = (193.75 + 7.75) dollars

                           = 201.50 dollars

Percentage of tips that Luca wants to give = 16%

Amount of tips that Luca wants to give = (16/100) * 201.50 dollars

                                                             = 32,24 dollars

The total amount that Luca needs to pay = (201.50 + 32.24) dollars

                                                                = 233.74 dollars

The answer is D
