Trent earns scores of 69, 88 and 73 on three chapter tests for a certain class. his homework grade is 63 and his grade for a class project is 69 . the overall average for the course is computed as follows: the average of the three chapter tests makes up 40% of the course grade; homework accounts for 20% of the grade; the project accounts for 20% ; and the final exam accounts for 20% . 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 70 or better, and 100 is the highest score that can be earned on the final exam. assume that only whole-number scores are given.

64 or more

Step-by-step explanation:

First, find the average of three tests scores:

Now

77 points - 40%

63 points - 20%

69 points - 20%

x points - 20%

Overall score must be 70 or better, so

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

y - 25 = 2 ( x - 10 ) should be the answer
