The state Department of Transportation wants to know about out-of-state vehicles that pass over a toll bridge

In a particular class, exams are worth 50% of the overall grade, quizzes are worth 30% of the overall grade, homework is worth 1

UkoKoshka [18]

Answer:

His overall grade is 81.9%

Explanation:

The easiest way to solve this question is by using simple cross multiplication.

1- His overall percentage in exams:

We are given that exams are worth 50% of the grade and that he scored an average of 82.2%

Assume that his overall percentage in exams is e

We can setup the ratio and solve for e as follows:

$\frac{82.2}{100}=\frac{e}{50} \\ \\e=\frac{50*82.2}{100}=41.1$ %

2- His overall grade in quizzes:

We are given that quizzes are worth 30% of the grade and that he scored 74.4%

Assume that his overall percentage in quizzes is q

We can setup the ratio and solve for q as follows:

$\frac{74.4}{100}=\frac{q}{30} \\ \\q=\frac{30*74.4}{100}=22.32$ %

3- His overall grade in homework:

We are given that homework is worth 15% of the grade and that he scored an average of 90%

Assume that his overall percentage in exams is h

We can setup the ratio and solve for h as follows:

$\frac{90}{100}=\frac{h}{15} \\ \\h=\frac{15*90}{100}=13.5$ %

4- His overall grade in class participation:

We are given that class participation is worth 5% of the grade and that he scored a 100% in it

Assume that his overall percentage in exams is p

Since he scored 100%, then he scored the complete worth which is 5%

p = 5%

5- His overall grade in the course:

The student's overall grade in the course is the summation of the above calculated percentages

This means that:

Overall grade = e + q + h + p

Overall grade = 41.1 + 22.32 + 13.5 + 5

Overall grade = 81.92% which is 81.9% approximated to one decimal place

Hope this helps :)

PLEASEEEEE HELPPPPPPP WILL MARK BRAINLIEST! AND 100 POINTS PLS !!

Answer:

A. The slope is -1/6

Step-by-step explanation:

A. The slope is indeed -1/6. Negative because it's going down towards the x and not up to where the y is at.

B. No, the slope represents Trisha's distance from the finish line.

C. No, the (26, 0) would be incorrect, it should be (0,26).

D. No, the y-intercept I think represents her starting point.

Forgive me if I'm wrong!

$~~~~~~\dfrac{2x-3}{4} = 3x\\\\\implies 2x-3 = (3x)(4)\\\\\implies 2x -3 = 12x \\\\\implies 12x -2x = -3\\\\\implies 10x = -3\\\\\implies x = -\dfrac{3}{10}$

X-2y=1 x+3y+z=0 2x-2z=18

balandron [24]

Answer:

Solve equation [2] for the variable z

[2] z = -x + 3y

// Plug this in for variable z in equation [3]

[3] 2x - 2•(-x +3?) = 18

[3] 4x = 18

// Solve equation [1] for the variable x

[1] x = 2y + 1

// Plug this in for variable x in equation [3]

[3] 4•(2?+1) = 18

[3] 0 = 14 => NO solution
