Luke earned a grade of 88% on his multiple choice history final that had a total of 200 problems. How many problems on the final exam did Luke answer correctly?

176

Step-by-step explanation:

88% = 88/100

88 × 2 = 176

176/200

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
