well, there are 128 oz in 1 gallon(US), so in 5856 oz there are 5856 ÷ 128 = 45.75 gallons(US).

58.56 gallons of milk,a person will drink in a leap year.

What is leap year?

A Leap Year has 366 days (the extra day is the 29th of February).

How to know if it is a Leap Year:

Leap Years are any year that can be exactly divided by 4 (such as 2016, 2020, 2024, etc)

except if it can be exactly divided by 400, then it is (such as 2000, 2400)

How many galllons will a person drink in a leap year?

We have given,

Average person drinks 16 ounces of milk in 1 day.

We have to find milk consume by average person in 366 days in gallons.

We know, 1 ounce (oz)=0.01 gallons

So, 16 ounce = 16×0.01 gallons

=0.16 gallons

We can say milk consume in one day = 0.16 gallons

Therefore,milk consume in 366 days(in gallons)=366×milk consume in 1 day.

=366×0.16

=58.56 gallons.

Answer:

(x - 2)² + (y +8)² = 49

Step-by-step explanation:

Points to remember

Equation of a circle passing through the point (x₁, y₁) and radius r is given by

(x - x₁)² + (y - y₁)² = r ²

To find the radius

It is given that, center of circle = (-5, -8) and passes through the point (2 -8)

By using distance formula,

r = √[(2 --5)² + (-8 --8)²]

 = √7²

r = 7

To find the equation of the circle

Here (x₁, y₁) = (2, -8)

Equation of circle is,

(x - x₁)² + (y - y₁)² = r ²

(x - 2)² + (y - (-8))² = 7²

(x - 2)² + (y +8)² = 49

Answer:

The equation of circle is [tex](x+5)^2+(y+8)^2=49[/tex].

Step-by-step explanation:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]              .... (1)

where, (h,k) is the center of the circle and r is the radius.

It is given that the center of the circle is (-5,-8). it means h=-5 and k=-8.

The circle passes through the point (2,-8). So, the radius of the circle is the distance between point (-5,-8) and (2,-8).

[tex]r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]r=\sqrt{(2-(-5))^2+(-8-(-8))^2}[/tex]

[tex]r=\sqrt{7^2+0}[/tex]

[tex]r=7[/tex]

Substitute h=-5, k=8 and r=7 in equation (1), to find the equation of circle.

[tex](x-(-5))^2+(y-(08))^2=(7)^2[/tex]

[tex](x+5)^2+(y+8)^2=49[/tex]

Therefore the equation of circle is [tex](x+5)^2+(y+8)^2=49[/tex].

Final answer:

By setting up an equation where the total costs for both electricians are equal and solving for h, we find that the number of hours for which the costs are the same is 4 hours.

Explanation:

To determine the number of hours, h, for which the cost would be the same for hiring both electricians, we set up an equation where both cost expressions are equal. The equation, which expresses the total cost for each electrician's services, is:

First electrician: Cost = $60 + $55h

Second electrician: Cost = $20 + $65h

We now equate the two expressions and solve for h:

$60 + $55h = $20 + $65h

$55h - $65h = $20 - $60

-$10h = -$40

Divide each side by -10: h = 4

Thus, the number of hours for which the costs are the same is 4 hours.

Final answer:

The number of hours for which both electricians would charge the same is 4 hours. We find this by setting up an equation based on their fees and hourly rates, solving this equation yields the result of 4 hours.

Explanation:

To determine the number of hours, h, for which the cost would be the same for hiring both electricians, we can set up an equation based on their charges. The first electrician charges a service call fee of $60 and $55 per hour. Therefore, the cost for the first electrician, C1, can be expressed as:

C1 = 60 + 55h

The second electrician charges a service call fee of $20 plus $65 per hour, which means the cost for the second electrician, C2, is:

C2 = 20 + 65h

To find when the costs are the same (C1 = C2), we set the two expressions equal to each other:

60 + 55h = 20 + 65h

Now we solve for h:

60 + 55h = 20 + 65h

55h - 65h = 20 - 60

-10h = -40

h = 4

The costs are the same when the electricians work for 4 hours.

Answer:

x² + 4y²+ 2x - 24y + 33 = 0

= (x+1)² + 4(y-3)² - 1 - 36 + 33 = 0

= (x + 1)²/2² + (y - 3)²/1² = 1

This is an Ellipse:  C(-1,3)

The Standard Form of an Equation of an Ellipse is : (x - h)²/a²/ (y - k)²/b² = 1

  Cassie is traveling 63.6 mph

Step-by-step explanation:

If the three numbers, left to right, are A, B, C, then the tire radius in millimeters is ...

  A×B/100 + 12.7×C

For the factory tires, the tire radius is ...

  240·75/100 + 12.7·16 = 180 +203.2 = 383.2 . . . . millimeters

For the replacement tires, the tire radius is ...

  290·70/100 +203.2 = 406.2 . . . . millimeters

The speedometer is calibrated based on the number of revolutions the tire makes in a given time period. If the truck goes farther for each revolution, its speed is higher by the same proportion.

If the speedometer on the truck with these replacement tires reads 60 mph, the actual speed is ...

  (406.2/383.2)×60 mph = 63.6 mph

Step-by-step explanation:

Under a reflection in y = x

a point (x, y) → (y, x)

Given

H(17, 34 ) → H'(34, 17)

I(- 5, 10) → I'(10, - 5)

J(28, - 14) → J'(- 14, 28)

B represents the image coordinates of H, I, J

For the given figure with vertices H(17,34), I(-5,10), and J(28,-14) across the line y=x, the reflection will appear at H(34,17), I(10,-5), J(28,-14). This is because at y=x the reflection will have the coordinates with interchanged values.

Across y=x, the reflection will have interchanged coordinates.

that is (x, y) → (y, x)

For the given vertices across the line y=x,

H(17,34) → H'(34,17)

I(-5,10) → I'(10,-5)

J(28,-14) → J'(-14,28)

So, option (2) is correct that is H(34,17), I(10,-5), J(-14,28) which undergoes reflection across y=x.

Step-by-step explanation:

The calculator function appears to be ...

  f(x) = {3x -1, x odd; x/2 +1, x not divisible by 4; x/4, x divisible by 4}

The inverse of the first function is ...

  x = 3y -1

  (x+1)/3 = y . . . . (y must be odd)

For x = 13, this is 14/3, which is not an integer.

__

The inverse of the second function is ...

  x = y/2+1

  2(x-1) = y . . . . (y must not be divisible by 4)

For x = 13, this is 2·12 = 24, which is divisible by 4, so 24 is not the input value.

__

The inverse of the third function is ...

  x = y/4

  4x = y . . . . (y must be, and is, divisible by 4)

For x = 13, this is 4·13 = 52.

The only possible input value for an output of 13 is 52.

  3022.08 . . . dollars per square meter

Step-by-step explanation:

The slope is multiplied by the factor that changes units:

  (280.76 dollars/ft²)×(1 ft²)/(.092303 m²) ≈ 3022.08 dollars/m²

To make predictions for house prices in square meters, you would have to multiply the given slope of 280.76 by the conversion factor of 1/0.092903, which will give an estimated slope of approximately 3017.9

The problem here is related to the conversion of units from square feet to square meters. Your friend gives you a simple regression fit for predicting house prices from square feet with an estimated intercept of -44850 and the estimated slope is 280.76.

Given that there are 0.092903 square meters in 1 square foot, a square foot equals to 1/0.092903 square meters. When you are making a prediction based on square meters rather than square feet, you need to consider this factor. This means the new slope would be calculated by multiplying the old slope with this conversion factor as:

Slope for prediction in square meters = Old slope * (1/0.092903) = 280.76 / 0.092903 = 3017.9 approximately.

Let x represents the new salary paid (In dollars ),

∵ The actual salary = $ 37,500

∵ Maximum difference in salaries = $ 4500

Case 1 : If x > 0
