How many feet are in 9 yards?

A. 45 ft

B. 18 ft

C. 36 ft

D. 27 ft

Answer Explanation:

The interconversion of yards to feet utilizes the relationship 1 yard =3 feet. Then, 9 yards to ft becomes

                                        t

There, 9 yards is equal to 27 ft.

Therefore, the Correct Answer is D.

  • Q #1: A class of 48 students has 22 boys and 26 girls. What is ratio of girls to boys in the class?

    A. 26:11

    B. 13:11

    C. 13:22

    D. 11:13

    Answer Explanation

    : a ratio can be thought of a fraction of the form a/b, where b is not equal to zero. In ratio form, to means per.

    Now, the class has 26 girls and 22 boys. Thus, the ratio of girls to boys becomes:

                                              

    The fraction above reduces into

                                         

     

    In ratio form, girls: boys=13:11

    Thus, the ratio of girls to boys in a class of 48 students is 13 to 11.

  • Q #2: If x represents the width of a rectangle and length is six less than two times the width, which of the following expressions represents the length of the rectangle in terms of x?

    A. 2x-6

    B. 6-2x

    C. 6x-2

    D. 3x-4

    Answer Explanation

    To form an equation from the word problem, first break the given statement into smaller statements.

    First, we are given the width of the rectangle as x. We are told, the length is two times width. Mathematically, this means

    Length=2*width=2*x=2x

    Now, the length is 6 less than 2 times width of the rectangle. Thus, the length of rectangle in terms of width becomes:

    Length =2x-6

    Thus, the length of the rectangle is 2x-6.

  • Q #3: 3(2x+5)=11x+5 Solve the equation above for x. Which of the following is correct?

    A. 1

    B. 2

    C. -1

    D. -2

    Answer Explanation

    We follow the order operations to solve for the unknown value of x.

    3(2x+5)=11x+5

    Open the bracket on the LHS by multiplying each term by 3

    (3*2x)+(3*5)=11x+5

    6x+15=11x+5

    Subtract 15 from both sides

    6x+15-15=11x+5-15

    6x=11x-10

    Subtract 11x on both sides

    6x-11x=11x-11x-10

    -5x=-10

    Divide both sides by -5

    -5x/-5=-10/-5

    x= 2

    Thus, the value of unknown value of x is 2.
