The Temperature Outside Is Currently 10F. It Will Fall At A Constant Rate Of 3F Per Hour. Which Temperature

Answers

Answer 1

Answer:

The temperature in 4 hours = -2 °F

Thus, option (D) is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the rate of change or slope and b is the y-intercept

Let 'y' be the temperature Let 'x' be the time of the temperature in the hour

Given that the current temperature outside = 10°F.

Thus, the y-intercept = b = 10°F

Given that as the day went on, It will fall at a constant rate of 3°F per hour.

Thus, the slope or rate of change = -3°F

(The rate of change or slope is -3 because the temperature is reducing)

Thus, the rate of change = slope = m = -3

Thus, substituting m = -3 and b = 10 in the equation

[tex]y = mx+b[/tex]

[tex]y = -3x + 10[/tex]

Now, substituting x = 4 to determine the temperature after 4 hours.

y = -3(4) + 10

y = -12 + 12

y = -2 °F

Therefore, the temperature in 4 hours = -2 °F

Thus, option (D) is true.

Your value to live in a quiet apartment is $400. The neighbor living above your apartment makes noise using her treadmill every day. She values running at $500. Your neighbor has the right to run in her apartment. If the proper conditions are met, what does the Coase Theorem suggest is the likely outcome in this case

Answers

Answer:

continuation

Step-by-step explanation:

Since you value a quiet apartment at $400, which is less than $500, you might offer $400 for your neighbor to stop, but she values running higher, so she would likely refuse, resulting in the continuation of what's happening.

The correct statement to the given query is "The neighbor pays you $401 to continue running".

Coase's theorem predicts that throughout the face of such an external cost, contracting groups or two entities would be prepared to arrange as well as achieve a satisfactory solution.Because of this, one's neighbor would then compensate them at minimum the worth of their condominium so that he would rather start operating upon the treadmills.

At ShopRite, chicken sells for $3.75 per pound. How much would it cost to buy 2.25 pounds of chicken?

Answers

Answer: 8.4375 U.S. dollars2

Step-by-step explanation:

Answer:

$8.44

Step-by-step explanation:

From the question it self we know that 1 pound of chicken costs $3.75. In order to solve this question we just need to find out how much 1 pound does fit into 2.25 pounds and then multiple the result by $3.75. We can find that out by dividing 2.25 by 1, and we get 2.25. Then we do the following....

2.25 x $3.75 = $8.4375

We got $8.4375 as an answer but we have to remember that when we are talking about money and we have to round to the nearest cent (which is equal to 1 hundredth of a dollar). So now we just have to round to the nearest hundredth, and we get $8.44 as our answer.

2. m<R+ m<S+m<T. Triangles must add up to 180°

3. 3x+2x+85°=180°. Substitution

4. X=19. Algebra

Step-by-step explanation:

So basically we look at angle UTV and it equals to 85 degrees. We have to find another angle that equals 85 degrees and to do this we have to find a vertical angle congruent angle which here is angle RTS and this equals 85 degrees.

Next just use sum of angles in triangle from RTS.

Then substitute the values from angle RTS.

3x + 2x + 85 = 180

Solve for x.

(2,-3), slope = 4
What is the answer

Answers

We are given:

The line passes through (2,-3)

Slope of the line = 4

Finding the equation of the line:

We know that the general form of the slope-intercept form is:

y = mx + b         [where m is the slope and b is the y-intercept]

y = 4x + b          [since slope = 4]

Finding the y-intercept:

Now, we are given that the line passes through the points: (2,-3)

which can be written as: x = 2 and y = -3

Since the line passes through these points, these values must satisfy the equation

So,

y = 4x + b

-3 = 2(4) + b

-3 = 8 + b

b = -11                [subtracting 8 from both sides]

Hence, the y-intercept is -11

Equation of the line:

We wrote the equation of the line as:

y = 4x + b          (where b is the y-intercept)

now that we know the value of b,

y = 4x - 11

Therefore, the equation of the line is: y = 4x - 11

Find the equation of the line through point (-3, 8) and perpendicular to y = x + 14. Use a forward slash (i.e. "M) for
fractions (e.g. 1/2 for 3).

Answers

Answer:

y+x = 5

Step-by-step explanation:

Given the equation y = x + 14

Get the slope first

The slope m = 1

Since the required equation is perpendicular to the line, the required slope will be M = -1/1 = -1

Get the required equation using the equation y-y0 = m(x-x0)

(x0, y0) = (-3, 8)

y - 8 = -1(x-(-3))

y-8 = -(x+3)

y-8 = -x-3

y+x = -3+8

y+x = 5

Hence the required equation of the line is y+x = 5

The product of three positive integers is 300. If one of them is 5, what is the
least possible value of the sum of the other two?
​

Answers

Answer and Step-by-step explanation:

So, we are told that 3 positive integers multiply to be 300, and that one of the integers is 5.

First, we divide 300 by 5.

The result is 60.

Now, we take different (reasonable) numbers that add to 16:

10 and 6

12 and 4

We can see here that 10 and 6 are the integers because they add up to 16 and multiplies to 60.
