6. Roberto, his sister, and a friend went out to dinner. The total bill for the three of them
came to $46. They decided to leave a 20% tip. If the bill is split evenly, how much should
each person pay?
Part I: Calculate 20% of $46. (Hint: Convert 20% to a decimal first.) (2 points)

each should pay $18.40

Step-by-step explanation:

bill: $46

20% of $46 is $9.20

total bill: $55.20

total bill split into 3: $55.20/3 = $18.40

They will each pay $18.40.

Step-by-step explanation:

you would calculate 20% of 46 and add the result to 46

Then you get $55.20 (This represents the total bill including the tip)  

Now you divide that total by 3 (three represents the 3 friends)

                               :)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

pls mark as brainliest

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
