Answer:

-191.10

Step-by-step explanation:

When you divide 56/23 you get 2.4, 2.4 is negative.

Multiply 2.4 6 times

2.4^6.

You get -191.10.

1. y=6

2. y=-12

Step-by-step explanation:

1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.

It is given that

y varies inversely as x

IT will be written as:

y∝1/x

Removing the proportionality symbol

y=k/x

Given

y=3 , x=-2

Putting the values

3=k/-2

k=3*-2 = -6

The equation will be:

y=-6/x

So,

When x=-1

$y=\frac{-6}{-1}\\y=6$

2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4

y is directly proportional to x

y∝x

y=kx

Given

y=15, x=-3

Putting the values

$y=kx\\15=-3k\\k=\frac{15}{-3}\\k=-5\\The\ equation\ will\ be:\\y=-3xNow,\\x=4\\y=-3(4)\\y=-12$

Hence,

1. y=6

2. y=-12

Marie gets a gift of $100 for her birthday. After that, she earns $20 per week for babysitting

Lostsunrise [7]

Answer:

y=20x+100

y-intercept= 100

slope= 20/1

Step-by-step explanation:

Since 100 is the constant, the y-intercept(b) is equal to 100. And if she earn's 20 dollars each week it's the changing amount.

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 :)
