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.

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.

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

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

Hey, CadenClough! For this, it's best to use algebra. We know that rectangles have two of each measure: two lengths and two widths. This means the formula to find the complete perimeter of the rectangle is 2l + 2w = p.

Now let's look at the problem. For length, we have x + 3 and for width we have 2x - 6. First off, fill in the values for length and width in the perimeter equation like this:

[tex]2(x + 3) + 2(2x - 6) = 26[/tex]

Now distribute the 2:

[tex]--> 2x + 6 + 4x - 12 = 26[/tex]

Combine like terms:

[tex]2x + 4x + 6 - 12 = 26[/tex]

Simplify:

[tex]6x - 6 = 26[/tex]

Isolate x:

[tex]6x = 26 + 6[/tex]

--> [tex]x = \frac{32}{6}[/tex]

Now plug in the value of x:

[tex]2(\frac{32}{6} + 3) + 2(2 * \frac{32}{6} - 6)[/tex]

= 64/3 - 12 + 32/3 + 6

= 26

So x = [tex]\frac{32}{6}[/tex] or 16/3.

Final answer:

The line that is parallel to 4x+3y=7 and passes through (-5,2) has the equation y=(-4/3)x-14/3.

Explanation:

The line that is parallel to the line with the equation 4x+3y=7 and passes through the point (-5,2) will have the same slope as the given line. To find the slope, we need to rearrange the equation into slope-intercept form (y=mx+b), where m is the slope. In this case, we get 3y=-4x+7, which can be simplified to y=-(4/3)x+7/3. So the slope is -4/3.

Now that we know the slope, we can use the point-slope formula y-y1=m(x-x1) to find the equation of the line that passes through (-5,2).

Using y-2=(-4/3)(x-(-5)), we can simplify to y-2=(-4/3)(x+5). Expanding and rearranging, we get y=(-4/3)x-14/3.

The equation of the parallel line is: [tex]\[\boxed{4x + 3y = -14}\][/tex]

To find the equation of a line parallel to the given line 4x + 3y = 7 and passing through the point (-5, 2), follow these steps:

1. Determine the slope of the given line:

The given line's equation is in standard form: Ax + By = C. To find its slope, we can rewrite it in slope-intercept form y = mx + b, where m is the slope.

Starting with the given equation:

4x + 3y = 7

Solve for y:

[tex]\[3y = -4x + 7\]\[y = -\frac{4}{3}x + \frac{7}{3}\][/tex]

The slope m of the given line is [tex]\(-\frac{4}{3}\).[/tex]

2. Use the slope of the parallel line:

Since parallel lines have the same slope, the line we are looking for also has a slope of [tex]\(-\frac{4}{3}\).[/tex]

3. Use the point-slope form to find the equation of the new line:

The point-slope form of a line's equation is given by:

[tex]\[y - y_1 = m(x - x_1)\][/tex]

where [tex]\((x_1, y_1)\)[/tex] is a point on the line, and m is the slope.

Here, the point (-5, 2) and slope [tex]\(m = -\frac{4}{3}\):[/tex]

[tex]\(-\frac{4}{3}\).[/tex]

[tex]\[y - 2 = -\frac{4}{3}(x + 5)\][/tex]

Simplify the equation:

[tex]\[y - 2 = -\frac{4}{3}x - \frac{4}{3} \cdot 5\]\[y - 2 = -\frac{4}{3}x - \frac{20}{3}\][/tex]

Add 2 (or [tex]\(\frac{6}{3}\))[/tex] to both sides:

[tex]\[y = -\frac{4}{3}x - \frac{20}{3} + \frac{6}{3}\]\[y = -\frac{4}{3}x - \frac{14}{3}\][/tex]

The equation of the line parallel to 4x + 3y = 7 and passing through (-5, 2) is:

[tex]\[y = -\frac{4}{3}x - \frac{14}{3}\][/tex]

Converting back to standard form for consistency:

[tex]\[3y = -4x - 14\]\[4x + 3y = -14\][/tex]

Therefore, the equation of the parallel line is:

[tex]\[\boxed{4x + 3y = -14}\][/tex]

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:

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.

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.

The correct  answer is b) 250.

Evaluate the exponent in the denominator:

[tex]\frac{5^8}{5^5}=5^{8-5}=5^3[/tex]

The subtraction of exponents arises from the rule that when you divide two terms with the same base, you subtract the exponents.

Substitute the result back into the original expression:

[tex]2 \cdot 5^3[/tex]

Calculate the final result:

[tex]2 \cdot 5^3=2 \cdot(5 \cdot 5 \cdot 5)=2 \cdot 125=250[/tex]

So, [tex]2 \cdot \frac{5^8}{5^5}[/tex]  simplifies to 250. The key step is understanding how to handle the exponents when you divide terms with the same base. In this case, it simplifies to [tex]5^{3}[/tex] , and then you can evaluate the expression further to get the final result of 250.
