We are given equation of total campsite charge

[tex]C=12d+8[/tex]

where

C is total campsite charge C (in dollars)

d is the number of days that the site is rented

so, here we will have

C is y-axis or dependent variable

d is x-axis or independent variable

we can find any two points and then we locate it

after that we can join them to get our graph

At d=0:

[tex]C=12\times 0+8[/tex]

[tex]C=8[/tex]

so, our point is (0,8)

At C=0:

[tex]0=12d+8[/tex]

[tex]-8=12d[/tex]

[tex]d=\frac{-2}{3}[/tex]

so, our point is [tex](\frac{-2}{3},0)[/tex]

now, we can locate these points and then join it

The equation C=12d+8 can be graphed by beginning with the y-intercept at (0,8) and using the slope of 12 to draw the line. This represents how the cost C changes with each day d the site is rented.

To graph the equation C=12d+8, you can start by considering 'd' (the number of days) and 'C' (the total cost) as x and y variables, respectively. This way, the equation becomes more familiar: y = 12x + 8.

First, plot the y-intercept (0,8) on the graph. The y-intercept is the constant term, which is 8 in this case. This means that even when you rent the site for zero days (d=0), you pay $8 for parking.

Second, the number 12 in the equation is the slope of the graph. This means that for each day you rent the site, the total cost increases by $12. To plot these changes, you may start at the y-intercept and then move up 12 units (the rise) and one unit to the right (the run) for each day.

Essentially, if you wanted to rent the site for one day (d=1), the total cost (C) would be 12*1 + 8 = $20. For two days, C = 12*2 + 8 = $32, and so on. Mark these points on your graph and connect them with a straight line, as this is a linear equation.

Answer:

In x-axis: [tex](7,-3)[/tex], In y-axis: [tex](-7,3)[/tex]

Step-by-step explanation:

The rule of the reflection of a point across the x-axis is as shown:

The reflection of the point [tex](x,y)[/tex] across the x-axis is given by [tex](x,-y)[/tex].

The point given to us is [tex](7,3)[/tex], when reflected across the x-axis we get:

[tex](x,-y)=(7,-3)[/tex]

Now, when a point [tex](x,y)[/tex] is reflected across the y-axis we get the point [tex](-x,y)[/tex].

So when the point [tex](7,3)[/tex] is reflected across the y-axis we get: [tex](-x,y)=(-7,3)[/tex].

Answer:

5ºF per hour decrease

Step-by-step explanation:

Given that the temperature in Fairbanks, Alaska, fell 10 degrees in 2 hours

For finding average we normally divide the total by number of units

Here change in temperature for 2 days is given as -10 degrees (negative sign is used to denote decrease)

For 2 days change in temperature = -10 degrees F

Hence average change in temperature = change for one day

= -10/2 = -5 degrees F

So answer is 5ºF per hourº decrease

Given : -2(5x+1) > 48

To solve for x  we need to get x alone

Lets start with removing parenthesis from left hand side

-10x -2 > 48

Now add 2 on both sides

-10x > 50

Divide by -10 from both sides. When we divide by negative number then flip the inequality sign, so > becomes <

x < -5

Answer is x< -5

Final answer:

The solution to the inequality -2(5x+1)>48 is found by distributing the -2, adding 2 to both sides, and then dividing by -10, remembering to reverse the inequality sign, resulting in x < 5.

Explanation:

To solve the inequality -2(5x+1)>48, we start by distributing the -2 across the parenthesis:

-2 * 5x - 2 * 1 > 48

-10x - 2 > 48

Now, we add 2 to both sides of the inequality to isolate the term with the variable x:

-10x > 48 + 2

-10x > 50

Next, we divide both sides by -10 to solve for x. Remember that dividing by a negative number reverses the inequality sign:

x < -50 / -10

x < 5

So, the solution to the inequality is x < 5.

Answer:

It would be 22:18, or 11:9 simplified.

The ratio is 11:9. To calculate the ratio of people who know how to ice skate to those who do not know, divide the number of skaters by the number of non-skaters.

The ratio of people who know how to ice skate to people who do not know how to ice skate can be calculated as:

Ratio = Number of people who know how to ice skate / Number of people who do not know how to ice skate

Ratio = 22 / 18 = 11 / 9

Therefore, the ratio of people who know how to ice skate to people who do not know how to ice skate is 11:9.

K(-4,8) is the ortho center.

Step-by-step explanation:

In a right angled triangle, The vertex of the right angle is the ortho center.

Here we are given

J(-4,-1), K(-4,8) & L(2,8)

Using distance formula we get

[tex]JK^{2}= (-4+4)^{2}+ (8+1)^{2}=0+81=81[/tex]

[tex]KL^{2}= (-4-2)^{2}+ (8+-8)^{2}=36+0=36[/tex]

[tex]JL^{2}= (-4-2)^{2}+ (8+1)^{2}=36+81=117[/tex]

So we can say that

[tex]JK^2 + KL^2=JL^2[/tex]

By converse of pythagorean theorem we get

[tex]<K = 90°[/tex]

Hence the Vertex of the right angle is K(-4,8)

K(-4,8) is the ortho center.

5.83  every second, and 840000 a year.

Lawyer makes 9.72 cents per second, $840000 per year.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Another example could be kilo gram to gram.

Given that,

Rate of lawyer bills = $350/hour

Now,

Amount of money per second ⇒

$350/hour = 350/(60×60)

$0.097/seconds = 9.7 cents per second.

Amount of money per year ⇒ $350/hour = $(350 × 50 × 48)/ year

$350/hour =$840000 per year.

We have (2/3)÷5 = 2/15 advertisments for 1 page;

Then, we have 98 · (2/15) = 12.2(6) advertisments for 98 pages;

The nearest whole page is 12.

Final answer:

To calculate the number of advertisement pages in a 98-page magazine with a ratio of 2⁆3 advertisement pages for every 5 pages, we find there are about 20 sets of 5 pages. Multiplying this by the advertisement ratio gives us 40⁆3, which rounds up to 13 pages of advertisements.

Explanation:

The student's question is: If a magazine has 98 pages, to the nearest whole page, how many pages of the magazine are advertisements, given that the publisher requires 2⁆3 of a page of advertisements for every 5 pages in a magazine?

To solve this, we will use a ratio approach:

First, we calculate the ratio of advertisement pages to total pages. The ratio is 2⁆3 : 5.

Next, we find out how many sets of 5 pages there are in a 98-page magazine. This is 98 divided by 5, which equals 19.6 or about 20 sets when rounded down since we can't have a fraction of a set.

To get the total number of advertisement pages, we multiply the number of sets by the advertisement ratio, which is 2⁆3. So, 2⁆3 * 20 = 40⁆3, which rounds up to 13 when converted to whole pages.

Therefore, approximately 13 pages of the magazine are used for advertisements.

You should draw approximately 0.825 cc of fluid from the U40 insulin vial into the syringe to administer 33 units of insulin to the patient.

To calculate the amount of fluid that should be drawn into the syringe from a U40 vial in order to obtain 33 units of insulin, you can use a simple proportion based on the concentration of insulin in the vial.

The concentration of the U40 vial is 40 units of insulin per cubic centimeter (cc) of fluid.

Let "x" be the amount of fluid (in cc) to be drawn from the vial to obtain 33 units of insulin.

You can set up the proportion as follows:

(40 units insulin) / (1 cc fluid) = (33 units insulin) / (x cc fluid)

Now you can cross-multiply and solve for "x":

40 x = 33 × 1

40x = 33

x = 33 / 40

x = 0.825 cc

So, you should draw 0.825 cc of fluid from the U40 vial to obtain 33 units of insulin.

The patient would need to draw approximately 0.825 cubic centimeters (cc) of fluid from the U40 insulin vial to obtain 33 units of insulin since the vial has 40 units per cc.

To calculate the amount of fluid that should be drawn into the syringe from a U40 insulin vial for a patient who needs 33 units of insulin, you can use the direct relationship between the units of insulin and the volume of fluid in the vial. Since the vial is labeled U40, it means it has 40 units of insulin per cubic centimeter (cc) of fluid.

Setting up a simple proportion, where the unknown volume in cubic centimeters is represented by 'V', the equation should look like this:

40 units of insulin / 1 cc = 33 units of insulin / V cc

By cross-multiplying, we have:

40 units * V cc = 33 units * 1 cc

Therefore, V = 33 units / 40 units/cc

After performing the division, V comes out to be just slightly under 1 cubic centimeter:

V ≈ 0.825 cc

So, the patient would need to draw approximately 0.82 cc or 0.825 cc (to be more precise) of fluid into the syringe from the U40 vial to obtain 33 units of insulin.

1.45kg of Sugar is left.

Step-by-step explanation:

First we have to make sure that both the values are represented in same units.

Lets convert 2.2kg to grams.

1 kilo gram is 1000 grams, So

2.2 kilo grams is, [tex]2.2*1000[/tex] grams. Which is equal to 2,200g.

So Bernard had 2,200g of sugar and he used 750g of it.

To find the remaining amount of sugar we need to deduct 750g from 2,200g.

[tex]2200-750=1450[/tex]

Therefore,

1450g of Sugar is left.

But the Answer should be given in kilo grams as the question requires you to do so.

So, convert grams to kilo grams you have to divide by 1000.

[tex]\frac{1450}{1000} =1.45[/tex] kilo grams.

1.45kg of Sugar is left.
