Answer:

Step-by-step explanation:

If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).

Final answer:

To find the speed of the current, we can set up equations for the boat's downstream and upstream speeds and solve for the current speed.

Explanation:

To find the speed of the current, let's assume the speed of the boat in still water is x mph. Since the boat's speed downstream is 60 mph, we can set up the equation:

(x + c) * t = 60

Where 'c' represents the speed of the current, and 't' represents the time taken. Similarly, the equation for the upstream speed of the boat (36 mph) can be written as:

(x - c) * t = 36

Simplifying these equations, we get:

x + c = 60/t

x - c = 36/t

Adding these equations, we obtain:

2x = 96/t

Solving for x, we get:

x = 48/t

Substituting this value back into one of the original equations, we can solve for t:

(48/t) + c = 60/t

Simplifying, we find:

c = 12/t

Therefore, the speed of the current is inversely proportional to the time taken for the downstream and upstream journeys.

19 percent of the people polled who preferred burgers were teachers.

Answer:

Option A is correct.

Step-by-step explanation:

According to results shown, we can say that option A is true.

In the burger column in above segment, we see that total number of students are 17 and total teachers are 4. Making it a total of 21.

So, [tex]\frac{4}{21}*100=19.04[/tex] ≈ 19% are teachers.

So, 19% of the polled people who preferred burgers were teachers.

Option B cannot be true as all the teachers were polled. Out of all 19% preferred burgers.

Option C is also not true because 19% was not from all the population. It was only from the teachers.

So, only option A is correct.

Answer:

x=10

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

7x-3 + 12x-7 = 180

Combine like terms

19x-10 = 180

Add 10 to each side

19x-10+10 = 180+10

19x = 190

Divide by 19

19x/19 = 190/19

x= 10

Answer:

10

Step-by-step explanation:

We are given a diagram which we are to analyze and and solve for x.

We can see the a straight line is intersected by another line thus forming two angles which are supplementary. It means that the sum of these angles is equal to 180 degree.

So we can write them as:

[tex] ( 7 x - 3 ) + ( 12 x - 7 ) = 180 \\\\ 12 x + 7 x = 180 + 3 + 7 \\\\ 19 x = 190 \\\\ x = \frac { 190 } { 19 }\\\\ x = 10 [/tex]

Therefore, the correct answer option is 10.

Answer:

[tex]x=2[/tex], [tex]y=0[/tex], or as an ordered pair [tex](x,y)=(2,0)[/tex].

Step-by-step explanation:

We have the system of equations

[tex]5x + 2y = 10[/tex] equation (1)

[tex]3x + 2y = 6[/tex] equation (2)

Since both equations have the term [tex]2y[/tex], we are using the elimination method:

Step 1. Multiply equation (2) by -1 and add the result equation to equation (1):

[tex]\left \{ {{-1(3x + 2y = 6)} \atop +{5x + 2y = 10}} \right.[/tex]

[tex]\left \{ {{-3x -2y = -6)} \atop +{5x + 2y = 10}} \right.[/tex]

Now we can get rid of [tex]-2y[/tex]

[tex]2x=4[/tex]

[tex]x=\frac{4}{2}[/tex]

[tex]x=2[/tex]

Step 2. Replace the value [tex]x=2[/tex] in equation (1) to find the value of [tex]y[/tex]:

[tex]5x + 2y = 10[/tex]

[tex]5(2) + 2y = 10[/tex]

[tex]10 + 2y = 10[/tex]

[tex]2y = 0[/tex]

[tex]y = 0[/tex]

We can conclude that the solution of the system of equations is [tex]x=2[/tex], [tex]y=0[/tex], or as an ordered pair [tex](x,y)=(2,0)[/tex].

The elimination method may not be applied directly to solve systems involving nonlinear, transcendental, or linearly dependent equations, demanding more complex techniques for solutions.

A system of equations cannot be directly solved by applying the elimination method if the system involves equations that are not linear or if the equations are dependent in such a way that one cannot eliminate variables easily.

For instance, in the case of two simultaneous transcendental equations, it may be impossible to solve the system through algebraic means using elimination.

In such scenarios, iterative methods like an extension of the Newton-Raphson technique might be necessary. Moreover, dealing with systems of differential equations also requires different approaches, such as the use of matrices or integrating factors when the equations are linearly dependent.

You should prepare a separate sheet with 3-5 references when an employer requests them, choosing them strategically and ensuring they agree to vouch for you.

Explanation:

When an employer asks for your list of references, you should be prepared to provide a separate sheet with this information, rather than listing it directly on your résumé. A generally accepted number of references is three, so the best answer to how many references should be ready to list if an employer asks for them is 3-5. These references could include a mix of superiors, co-workers, clients, or instructors. It is important to contact each reference to confirm their willingness to speak on your behalf and to ensure your reference sheet is consistent with the look of your cover letter and résumé. Moreover, always choose references strategically, selecting those who can positively attest to your skills, knowledge, and work habits.

A circle is a curve sketched out by a point moving in a plane. The area of sector BEC when CE = 9 yd is 84.823 yds².

The sector of a circle is like a slice of a circular pizza. Its two straight edge's having an angle, and the edge's length(the radius of the circle) are two needed factors for finding the area of that sector.

Since the whole circle with radius 'r' units have 360 degrees angle on the centre of the circle, and its area is

πr² unit², thus, as the angle lessens, this area gets lessened.

360 degree => πr² unit²

[tex]\rm area\ 1 degree = \pi r^2 \: \rm unit^2/360 area\\\\x\ degree = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]

Thus, the area of a sector with edge length 'r' units and interior angle 'x' degrees is given as:

Given the length of the radius of the circle, CE is 9 yds. Also, the measure of the ∠BEC at the centre of the circle is 120°. Therefore, the area of sector BEC can be written as,

Area BEC = π × r² × (θ/360°)

                 = π × 9² × (120° / 360°)

                 = 84.823 yds²

To identify the cup that is not within the specified tolerance, calculate the upper and lower limits of the tolerance and compare them to the actual diameter of each cup in the sample. The fourth cup with a diameter of 5.5in is not within the specified tolerance.

In this question, we are given the tolerance for the diameter of the cup's mouth, which is 5in ± 8%. We have a sample of cups with their diameters listed in a table. To identify the cup that is not within the specified tolerance, we need to calculate the upper and lower limits of the tolerance and compare them to the actual diameter of each cup in the sample.

To calculate the upper limit, we add 8% of 5in to the nominal value of 5in. This gives us 5in + 0.08 * 5in = 5in + 0.4in = 5.4in. To calculate the lower limit, we subtract 8% of 5in from the nominal value of 5in. This gives us 5in - 0.08 * 5in = 5in - 0.4in = 4.6in. Now, we compare the actual diameters of the cups in the sample to these upper and lower limits to determine which cup is not within the specified tolerance.

Looking at the table of cup diameters, we can see that the fourth cup has a diameter of 5.5in, which is greater than the upper limit of 5.4in. Therefore, the fourth cup is not within the specified tolerance.
