The AMC 10 and 12 contests consist of 25 questions. Students receive 6 points for each correctly answered question, 1.5 points for each question left blank, and 0 points for each incorrect answer.

Phyllis took the AMC 12. She answered 20 questions and got 16 of them correct. What was her score?

[jagged aurora]

The remaining 4 questions were left blank, so she earned 4 x 1.5 = 6 points for those.

For the 16 questions she answered correctly, she earned 16 x 6 = 96 points.

Her total score is the sum of the points earned for both the correct answers and the blank questions, which is 96 + 6 = 102 points.

Therefore, Phyllis' score on the AMC 12 is 102.

i got it wrong

[jagged aurora]

I'm sorry to hear that. Can you please let me know what your answer was and how you calculated it? I'd be happy to help you understand where you went wrong and provide further assistance.

[cerulean meteor]

my answer was 102 and I dont know how I got it wrong

[jagged aurora]

If your answer was 102 and the question was about Phyllis' score on the AMC 12, then your answer is correct.

As we calculated earlier, Phyllis earned 96 points for the 16 questions she answered correctly and 6 points for the 4 questions she left blank, making her total score 102.

It's possible that the question was asking about a different contest or had a mistake in it, but based on the information you provided, your answer of 102 is correct.

The AMC 10 and 12 contests consist of 25 questions. Students receive 6 points for each correctly answered question, 1.5 points for each question left blank, and 0 points for each incorrect answer.

Write a program that takes as input the number of questions answered and the number the questions gotten correct. The output should be the student's score.

numAnswered = int(input("Enter the number of questions answered: "))
numCorrect = int(input("Enter the number of questions correct: "))

you need to fill this part!

print("The student's score is: " + str(score))

[jagged aurora]

Sure! Here's a code snippet you can use to calculate the student's score based on the number of questions answered and the number of correct answers:

numAnswered = int(input("Enter the number of questions answered: "))
numCorrect = int(input("Enter the number of questions correct: "))

# Calculate the score for the student
score = (numCorrect * 6) + ((numAnswered - numCorrect) * 1.5)

print("The student's score is: " + str(score))

In this code, we first take user input for the number of questions they answered and the number they got correct and convert them to integers using the int() function.

Next, we calculate the score based on the number of correct answers and the total number of questions answered. We multiply the number of correct answers by 6 (since each correct answer is worth 6 points) and multiply the difference between the total questions answered and the number of correct answers by 1.5 (since each blank question is worth 1.5 points).

Finally, we print out the calculated score using the print() function, along with a helpful string.

I hope this helps!

There are two 3-digit numbers $n$ having the property that $n$ is divisible by 11 and $\dfrac{n}{11}$ is equal to the sum of the squares of the digits of $n$.

Find both values of $n.$

[jagged aurora]

Let's call the two 3-digit numbers $n_1$ and $n_2$, where $n_1 < n_2$. We know that:

$$n_1 \equiv 0 \pmod{11}$$

and

$$\frac{n_1}{11} = a^2 + b^2 + c^2$$

where $a$, $b$, and $c$ are the digits of $n_1$.

Since $n_1$ is a 3-digit number, $a$, $b$, and $c$ each must be between 0 and 9 (inclusive). However, since we know that $\frac{n_1}{11}$ is an integer, $a^2 + b^2 + c^2$ must be an integer divisible by 11. This means that $a^2 + b^2 + c^2$ must be a multiple of 11.

Since $a$, $b$, and $c$ are each between 0 and 9, the smallest possible value of $a^2 + b^2 + c^2$ is $0 + 0 + 1^2 = 1$, and the largest possible value is $9^2 + 9^2 + 9^2 = 243$. Therefore, the only possible values of $a^2 + b^2 + c^2$ that are multiples of 11 are 11, 22, 33, 44, 55, 66, 77, 88, and 99.

We can now try each of these values of $a^2 + b^2 + c^2$ one by one and see which ones satisfy $\frac{n_1}{11} = a^2 + b^2 + c^2$ and also result in a 3-digit number $n_1$.

If we try $a^2 + b^2 + c^2 = 11$, we get $\frac{n_1}{11} = 1$, which implies that $n_1$ must be 11 or 22. Both of these numbers are less than 100, so they don't qualify as 3-digit numbers.

If we try $a^2 + b^2 + c^2 = 22$, we get $\frac{n_1}{11} = 2$, which implies that $n_1$ must be 22 or 44. Again, these numbers are less than 100, so they don't work.

If we try $a^2 + b^2 + c^2 = 33$, we get $\frac{n_1}{11} = 3$, which implies that $n_1$ must be 33 or 66. Only 66 satisfies the condition of being a 3-digit number and being divisible by 11. We have found our first solution: $n_1=66$.

If we try $a^2 + b^2 + c^2 = 44$, we get $\frac{n_1}{11} = 4$, which implies that $n_1$ must be 44 or 88. Both of these numbers are greater than 1000, so they don't qualify as 3-digit numbers.

If we try $a^2 + b^2 + c^2 = 55$, we get $\frac{n_1}{11} = 5$, which implies that $n_1$ must be 55 or 110. Both of these numbers are less than 1000, but only 110 is a 3-digit number. However, 110 is not divisible by 11, so it doesn't work.

If we try $a

^2 + b^2 + c^2 = 66$, we get $\frac{n_1}{11} = 6$, which implies that $n_1$ must be 66 or 132. However, 132 is not divisible by 11, so it doesn't work. Therefore, our second solution is $n_2=132$.

So the two 3-digit numbers that satisfy the given conditions are $\boxed{66}$ and $\boxed{132}$.
