Answer:

346 square inches

Step-by-step explanation:

Let's say you have a piece of paper that measures 2.3 inches by 2 inches.the area is 4.6 square inches. The closest whole number is 5, so rounded to the nearest square inch is 5 square inches. Fractions equal to half or greater get rounded up to the next whole number. Fractions less than half get rounded down. SO that means that 346.49 should be rounded down to just 346 although it may be almost 50.

You read a steam and leaf plot in this way: the first column is the first digit of the score, and we're grouping scores by their first digits.

So, for example, if we read the row starting with 5, we deduce that there have been three scores in the 50's, namely two 57 and one 58.

To answer the question, we have to count how many occurrences we have in the row of the 70's and higher.

We have 4 scores in the 70's: 70, 70, 71, 78

We have 4 scores in the 80's: 82, 84, 87, 88

We have 3 scores in the 90's: 91, 93, 97

Answer:

The area of the table is [tex]1,008\ in^{2}[/tex]

Step-by-step explanation:

Let

x----> the length of the rectangular table

y---> the width of the rectangular table

we know that

The perimeter is equal to

[tex]P=2(x+y)[/tex]

[tex]P=132\ in[/tex]

so

[tex]132=2(x+y)[/tex]

[tex]66=x+y[/tex] ------> equation A

[tex]x=1\frac{3}{4}y[/tex]

[tex]x=\frac{1*4+3}{4}y[/tex]

[tex]x=\frac{7}{4}y[/tex] ---> equation B

substitute equation B in equation A and solve for y

[tex]66=\frac{7}{4}y+y[/tex]

[tex]66=\frac{11}{4}y[/tex]

For this case we have the following quadratic function:

[tex]f (x) = x ^ 2 + x-6[/tex]

We must find its roots. We can factor, looking for two numbers that when added to +1 and multiplied by -6. These are:

+3 and -2

[tex]+ 3-2 = 1\\(+3) * (- 2) = - 6[/tex]

Then, the factored form is:

[tex](x + 3) (x-2) = 0[/tex]

So, the roots are:

[tex]x_ {1} = - 3\\x_ {2} = 2[/tex]

Answer:

[tex]x_ {1} = - 3\\x_ {2} = 2[/tex]

Final answer:

To find 65% of a number, use the equation 0.65x = 32.5 and solve for x by dividing both sides by 0.65 to get x = 50.

Explanation:

Sixty-five percent of what number is 32.5?

Let's denote the unknown number as x.

Translate the given information into an equation: 0.65x = 32.5

To solve for x, divide both sides by 0.65 giving x = 32.5 / 0.65 = 50.

Answer:

  4 -i

Step-by-step explanation:

For your condition to be met, neither the real part nor the imaginary part can exceed √17 in magnitude. That excludes the first three answer choices.

The magnitude of 4-i is ...

  √(4^2 +(-1)^2) = √17.

Answer:

Step-by-step explanation:

First, we need to know that a complex number, which has a real part and an imaginary part, it's like a vector, where the horizontal coordinate is the real part, and the vertical coordinate is the imaginary part.

So, to find the distances we applied the conventional definition:

[tex]d=\sqrt{r^{2}+i^{2} }[/tex]

Where [tex]r[/tex] refers to the real part and [tex]i[/tex] refers to the imaginary part.

So, we test each answer and see which one gives us the root of 17.

[tex]d=\sqrt{2^{2}+15^{2} }=\sqrt{4+225}=\sqrt{229}[/tex]

[tex]d=\sqrt{17^{2}+1^{2} }=\sqrt{290}[/tex]

[tex]d=\sqrt{20^{2}+(-3)^{2} }=\sqrt{409}[/tex]

[tex]d=\sqrt{4^{2}+(-1)^{2} }=\sqrt{17}[/tex]

Therefore, the right answer is the last one, because the distance is the squared root of 17.

Given a rectangle with a perimeter of 24 ft where the length is 4 ft longer than the width, we find that the length is 8 ft and the width is 4 ft by setting up and solving an equation based on the formula for the perimeter of a rectangle.

The subject of this question is about finding the length and width of a rectangle given the perimeter and a relationship between the length and width. The formula for the perimeter of a rectangle is 2 * (length + width). If a rectangle has a perimeter of 24 ft, and the length is 4 ft longer than the width, we can add the length and width together and multiply by 2 to calculate the perimeter.

Let's call the width 'w'. Then the length will be 'w + 4'. From the information given, we have:

Therefore, the width of the rectangle is 4 ft. This means that the length, which is 4 ft longer than the width, is 4 + 4 = 8 ft. So the length of the rectangle is 8 ft.

D) They are opposite and parallel.

Step-by-step explanation:

Given:

There are two vectors "a" and "b" have opposite directions having the same magnitude of 7.

If the two vectors "a" and "b" have opposite directions mean one moves right and other moves left.

Which means they are opposite.

Here they have a same magnitude of 7. So they are parallel.

Therefore, the answer is D) They are opposite and parallel.

Answer:

Correct choice is C. 2 mL.

Step-by-step explanation:

Given that Ampicillin 250 mg IM every 12 hours is ordered. After reconstitution, there's 125 mg/mL. Now we need to find about how many mL would you give.

Let number of ml needed = x.

Since ratio of mg per mL will be fixed so we get equation:

[tex]\frac{mL}{mg}=\frac{x}{250}=\frac{1}{125}[/tex]

[tex]\frac{x}{250}=\frac{1}{125}[/tex]

[tex]x=\frac{1}{125} \times 250[/tex]

[tex]x=\frac{250}{125}[/tex]

[tex]x=2[/tex]

Hence correct choice is C. 2 mL.

Final answer:

To calculate the volume of ampicillin to be given, divide the ordered dose by the concentration of the solution. For a dose of 250 mg and a concentration of 125 mg/mL, the volume to administer is 2 mL. The correct option is: 2ml.

Explanation:

The question is asking us to calculate the volume of ampicillin required for one dose when it has been reconstituted to a concentration of 125 mg/mL, and the ordered dose is 250 mg given intramuscularly (IM) every 12 hours. To find out how many mL of the ampicillin solution should be administered in one dose, we use the formula:

Dose ordered / Concentration of solution = Volume to administer

In this case:

250 mg (Dose ordered) / 125 mg/mL (Concentration) = 2 mL

Therefore, you would administer 2 mL of the reconstituted ampicillin solution.

Every state has different requirements for obtaining a high school diploma. And each school varies greatly in what type of classes they offer. There are, however, a number of classes that are available, and perhaps even mandatory, in most high schools.

The courses your teen takes will also vary depending on his plans beyond high school. Students who plan to go to college may be required to take more years of a foreign language. Or a student who plans to major in engineering may want to take more math and science classes to prepare for college.

Students in a vocational track may be able to gain some hands-on learning. Many of them are even able to gain certificates or licenses that will help them in their future careers.

It's important to talk to your teen about her aspirations. Help her explore various career options.

Also, talk about what courses she plans to take in high school. Discuss her interest areas and review her schedule together. In addition to the basic classes, there are usually plenty of opportunities for your teen to take electives in various areas of study.

If Jake's study time can be represented as 'x', then, given that Julie studied twice as long as Jake, her study time can be represented as '2x'. This is because she studied twice the amount of time that Jake did.

The question describes a relationship between the amount of time Jake studied and the amount of time Julie studied. We know from the question that Julie studied twice as long as Jake did. In mathematical terms, we would represent Jake's studying time as x hours, since we don't have a specified amount. Therefore, because Julie studied twice as long as Jake did, we can represent Julie's studying time as 2x.
