Claire's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y represented by the equation y = 56 + 7.1x, where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 92?

the change in expected quiz for every additional one hour students spend on their homework.

a student's expected quiz score if they spent 1 hours on their homework.

the number of hours a student should spend on their homework to expect a score of 92 on the quiz.

a student's expected quiz if they spent 92 hours on their homework.​

Answers

Answer 1

Answer: t = 5.7 hours

Step-by-step explanation:

y=56+7.1x where x is the time spent studying.  If y=92, this equation would preduct that the student spent t hours studying.  Find t:

92=56+7.1x

36=7.1t

t = 5.07 hours to achieve the 92 score.

Two students, Galen and Mai, worked on a project.
Galen worked for 3 2/3 hours.
Mai worked for 2 4/5 hours.
What was the total time spent on the project?
How much more time did Galen spend on the project than Mai?

Answers

Answer:

Mia worked 4/5 of an hour less than Galen.

or

Galen spent 4/5 of an hour more working on the project.

Step-by-step explanation:

First we have to find the LCM (Lowest Common Multiple) of 5 and 3 -

3: 3, 6, 9, 15, 18, 21, 24, 27, 30

5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50

We can see here, that the lowest common multiple is 15.

Now we need to convert the 2/3 and 4/5 into fractions that are equivalent to something fraction that has the denominator of 15.

2/3x5= 10/15

4/5x3= 12/15

So, now, the hours of work time of both Galen and Mia are having the same denominator, now, we can subtract.

3 10/15 - 2 12/15 = 12/15

Now, we understand that 12/15 was the amount of time Galen worked more than Mai. But, still, there is still more to do.

Suspense......

SIMPLIFY!!!

12/15 both come in 3's multiplication table.

12/15 divided by 3 = 4/5

Now, our final answer simplified is 4/5.

Explanation: The total miles she rides is the miles she rides to school + the miles she rides back

Step 1: Convert both mixed numbers into fractions.

2 3/4 = 11/4

3 5/6 = 23/6

Step 2: Find GCF by multiplying both fractions by opposing denominators

11/4 = 66/24    (11 * 6 = 66, 4 * 6 = 24)

23/6 = 92/24    (23 * 4 = 92, 6*4=24)

Step 3: Add both fractions

92/24 + 66/24 = 158/24

Step 4: Simplify

158/24= 79/12 = 6 7/12 miles

The finance charge for the car loan Sarah took rounded to the nearest 100 dollars is 700 dollars.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted in decimals by dividing the percentage value by 100 it can also be simplified to keep it in a fraction form.

Given Sarah is taking a loan of 24,400 dollars for a new car.

Also given is the finance charge for this car loan is 2.88%.

We know 2.88% of 24400 dollars is,

= (2.88/100)×24400 dollars.

= 0.0288×24400 dollars.

= 702.72 dollars.

leni can decorate the room in 4 hours. her sister lucy do the same jobin 3 hours working together, how long will take them to finish the job

Answers

Fractions are integers that have both a numerator and a denominator. They are represented as; [tex]\frac{x}{y}[/tex]

Where:

x = Numerator

y = Denominator.

It will take them both [tex]\frac{7}{12}[/tex] hours or 0.583 hours to finish the job together.

To solve the above question, we would be applying the operations of the addition of fractions.

From the question,

Leni can decorate the room in 4 hours. This means in 1 hour, Leni can paint 1/4 of the room.

Lucy, her sister can decorate the room in 3 hours. This means in 1 hour, lucy can decorate 1/3 of the room.

Let us represent the number of hours it will take them both to decorate the room working together as "T"

Hence,

1/T = 1/4 + 1/3

Lowest Common Denominator for (3, 4 ) = 12

Hence,

1/T = 3 + 4 / 12

1/T = 7/12

Find the reciprocal of both sides

T = 7/12 hours or can be expressed in decimals as 0.583 hours.

Therefore, it will take them both [tex]\frac{7}{12}[/tex] hours or 0.583 hours to finish the job together.

Find the following:

f(g(x)) = 4*g(x) = 4*x/4 = xg(f(x)) = f(x)/4 = 4x/4 = x

Since f(g(x)) = g(f(x)) = x, the functions are inverses of each other.

1. Step 1: Rewrite into an equation.

[tex](6x+44) + (-10x+65) = 117[/tex] [tex]6x + 44 - 10x + 65 = 117[/tex]

Step 2: Simplify both sides of the equation.

[tex](6x-10x) + (44+65) = 117[/tex] [tex]-4x + 109 = 117[/tex]

Step 3: Subtract 109 from both sides.

[tex]-4x + 109 - 109 = 117-109[/tex] [tex]-4x = 8[/tex]

Step 4: Divide both sides by -4.

[tex]\frac{-4x}{-4}=\frac{8}{-4}[/tex] [tex]x = -2[/tex]

Therefore, x = -2 for the first one.

2. Step 1: Rewrite into an equation.

Step 2: Simplify both sides of the equation.

[tex](-16x-20x)+(13+23)=180[/tex] [tex]-36x +36 = 180[/tex]

Step 3: Subtract 36 from both sides.

[tex]-36x + 36 - 36 = 180 - 36[/tex] [tex]-36x = 144[/tex]

Step 4: Divide both sides by -36.

[tex]\frac{-36x}{-36} = \frac{144}{-36}[/tex] [tex]x = -4[/tex]
