Trent earns scores of and on three chapter tests for a certain class. his homework grade is and his grade for a class project is . the overall average for the course is computed as follows: the average of the three chapter tests makes up of the course grade; homework accounts for of the grade; the project accounts for ; and the final exam accounts for . what scores can trent earn on the final exam to pass the course if he needs a "c" or better? a "c" or better requires an overall score of or better, and is the highest score that can be earned on the final exam. assume that only whole-number scores are given.

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

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:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
