suppose y varies directly with x, and y=25 when x=140. what is the value of y when x=36

Answer:

2n

Step-by-step explanation:

Pythagoras [tex]a^{2} + b^{2} = c^{2}[/tex]

2 squared plus 2 squared = 8 but you need to find out the root of 8,

square root of 8 is a surd, so answer in that

Answer:

4n

Step-by-step explanation:

a^2+b^2=c^2

2n^2+2n^2=c^2

4n^2=c^2

sqrt 4n^2=sqrt c^2

4n=c

Given:

Total number of problems = 24

Michael completed [tex]\dfrac{1}{4}[/tex] of his homework in [tex]\dfrac{3}{4}[/tex] of an hour.

To find:

What fraction of his homework would he complete in one hour.

Solution:

We have,

Part of work done in [tex]\dfrac{3}{4}[/tex] of an hour [tex]=\dfrac{1}{4}[/tex]

Part of work done in an hour [tex]=\dfrac{4}{3}\times \dfrac{1}{4}[/tex]

                                                [tex]=\dfrac{1}{3}[/tex]

Therefore, he complete [tex]\dfrac{1}{3}[/tex] of his homework in 1 hour. Hence, all options are incorrect.

Answer:

S = {ABC, ABD, ACD, BCD}

Step-by-step explanation:

We are told that Ariana, Boris, Cecile, and Diego are students in the service club.

Let's denote their names with letters;

Ariana = A

Boris = B

Cecile = C

Diego = D

We are told that Three of the four students will be chosen to attend a conference. This means that the sample space will be a set showing combination of any 3 out of the 4 students.

Thus, sample space is;

S = {ABC, ABD, ACD, BCD}

Answer:

A

Step-by-step explanation:

Given:

Total savings = $400

Ratio of savings of Blake and Josh = 3:1

To find:

The saving of each.

Solution:

Let the savings of Blake and Josh are 3x and x respectively.

According to the question,

[tex]3x+x=400[/tex]

[tex]4x=400[/tex]

Divide both sides by 4.

[tex]x=100[/tex]

Now,

Savings of Blake = 3(100)=300

Savings of Josh =100

Therefore, the savings of Blake and Josh are $300 and $100 respectively.

Answer:

200l

Step-by-step explanation:

3/8 = 15l

1/8 = 15l/3

1/8 = 5l

1 = 5l × 8

1 = 40l

5 = 5×40l

5 = 200l

Answer:

you find slope from a table by taking any two points. the left side is the input of the table, the x, and the right side is the output the y. whenever you're finding the points to do slope, they must be correlated.

__x__|__y__

___2_|__4___

__3__|___6__

so if you want to choose 2 for the x input then you must choose the 4 as the y output.

After choosing the two points, (2,4) and (3,6), you need to find the slope which is y-y/x-x. so in this case it's 6-4/3-2. after subtracting you get, 2/1 which if you simplify, it's 2. Or you divide which is also 2. I hope this helped.

Answer:

$15.22

Step-by-step explanation:

Given that :

Cost of NFL game = $60

Amount Rico has in bank account = $24.78

Amount earned for mowing lawn = $20

Amount needed more to buy the game :

Total amount Rico has :

Cost of NFL game - (Amount in bank + amount earned for mowing)

$60 - ($24.78 + $20)

$60 - $44.78

= $15.22

Amount needed more to purchase the game = $15.22

Answer:

3x - 4

Step-by-step explanation:

-9x + 12

divide by -3

3x + (-4)

Answer:

Following are the solution to this question:

Step-by-step explanation:

It was right because the "Two" is "2," "more is" and "+" are two the most hours than Nandini and "n," so 2+n or n+2 is a true, phrase of Nandini's transcription".

Now, this vector n is unknown, so the number of hours Nandini researched should reflect.

Two further hours which Nandini researched Xander. So, Xander studied the number of hours = n + 2 or 2+ n. Kalley has therefore written a correct word.

Answer:

It is accurate. In the phrase “two more hours than Nandini,” “two” is “2,” “more” is “+,” and Nandini’s study time is unknown or “n,” so 2 + n or n + 2 are correct translations.

Answer:

153* for both

Step-by-step explanation:

This makes a circle, which is 360*. One angle is given, and it is 27*. If the angle on the opposite side is the same, the total degrees so far would be 54.

Say b and c were equal. Then, the remaining 306* would be split even among them. 306/2 is 153.

Therefore, 153* is the correct answer.

Hope I helped!!!

Answer:

See below.

Step-by-step explanation:

Divide the percentage to find the decimal form.

[tex]\frac{7.5}{100} =0.075[/tex]

Multiply the total by the percentage.

[tex]50*0.075=3.75[/tex]

Add that to the total.

[tex]50 +3.75=53.75[/tex]

Answer: [tex]53.75[/tex]

Answer:

sorry i wish i knew how but i would like to give you aomething other than an answer for your question and i hope this is ok.

Step-by-step explanation:

every day is a new day and a new opportunity to change the world no matter how BIG or how small.  even if you make mistakes. always remember this though. whatever you put into the world, whether it be good or bad, it will always come back three times.

meaning that when you do something good something three times as good will happen to you. The same is so for bad except it would be 3 times as bad as will happen to you.   I hope your day is great and may you do many great things.

Answer:

y = -x + 2

Step-by-step explanation:

For any linear equation, the equation of the line can be written in the form 'y=mx+c'. In this form, m is the slope and c is the y-intercept. We can figure out both these things using the graph.

The slope is like the incline/decline and can be found by getting two points on the line, say (x1,y1) and (x2,y2) and using the following formula:

m = (y2-y1) / (x2-x1)

So lets take two points: (-1,3) and (2,0)

m = (0-3)/(2-(-1))

m = -3/3

m= -1

The y intercept (c) is the value for x when the line crosses the y-axis.

From the graph we can see that the line crosses the y axis when x=2

∴ c = 2

Now that we know the slope and intercept, we just sub them into the formula:

y = mx +c

y = -x + 2

Let me know if you have questions :)

Answer:

y equals -x plus 2

Step-by-step explanation:

for any linear equation, the equation of the line can be written in the form 'y=mx+c'. In this form, m is the slope and c is the y-intercept. We can figure out both these things using the graph.

the slope is like the incline or decline and can be found by getting two points on the line, say (x1,y1) and (x2,y2) and using the following formula:

                       m = (y2-y1) / (x2-x1)

Answer:

x = -9/2  or -4.5

Step-by-step explanation:

-2x-5=4

Add 5 to each side

-2x-5+5=4+5

-2x = 9

Divide each side by -2

-2x/-2 = 9/-2

x = -9/2  or -4.5

Answer:

g(x) will be 4 units under f(x), and will be parallel.

Step-by-step explanation:

The only thing changing is the constant, or y-intercep. This is shown in -4, so 4 units lower. Slope will stay the same because it has not been modified in the expression for g(x).

Answer:

The graph of g(x) is the graph of​​ ​f(x)​ translated 4 units down.

Step-by-step explanation:

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
