    Explanation
    A proportion is a set of two equal fractions or ratios. In a proportion, the numerator of one fraction is equal to the numerator of the other fraction, and the denominator of one fraction is equal to the denominator of the other fraction. This means that the two fractions are equivalent and represent the same value. Therefore, both fractions and ratios can be used to describe a proportion.

    Hank just finished his meal at a restaurant and received the $26 bill. He would like to leave a 10% tip to show his appreciation for the great service.Select all equations that would help Hank calculate his total bill including tip.

    Correct Answer(s)
    A.
    B.
    Explanation
    Hank wants to leave a 10% tip on his $26 bill. To calculate the tip amount, he needs to multiply the bill amount by 10% (or 0.10). So, the equation that would help Hank calculate his tip is: Tip = $26 * 0.10.

    Hank just finished his meal at a restaurant and received the $34 bill. He would like to leave a 15% tip to show his appreciation for the great service.Select all equations that would help Hank calculate his total bill including tip.

    Correct Answer(s)
    A.
    B.
    Explanation
    Hank wants to leave a 15% tip on his $34 bill. To calculate the tip amount, he needs to multiply the bill amount by 15% (or 0.15). This can be represented by the equation: Tip amount = $34 * 0.15. To calculate the total bill including the tip, Hank needs to add the tip amount to the original bill amount. This can be represented by the equation: Total bill = $34 + Tip amount.

    What is the area of a circle with a circumference of ?

    Correct Answer
    D.
    Explanation
    If the circumference is 20pi, then the radius is 10. Square 10 to get 100. The area is 100pi.

    Rate this question:

  • 14. 

    Hank just finished his meal at a restaurant and received the $32 bill. He would like to leave a 20% tip to show his appreciation for the great service.Select all equations that would help Hank calculate his total bill including tip.

    Correct Answer(s)
    A.
    B.
    Explanation
    To calculate the total bill including the tip, Hank needs to add the tip amount to the original bill amount. Since he wants to leave a 20% tip, he can multiply the bill amount by 0.2 to find the tip amount. Then, he can add the tip amount to the bill amount to get the total bill including tip. The equation that represents this is: Total bill = Bill amount + (Bill amount * 0.2).
