Answer:

The radius is decreatsing at a rate 0.78 cm per second.

Step-by-step explanation:

We are given the following in the question:

[tex]\dfrac{dl}{dt} = 0.7\text{ cm per second}[/tex]

Instant radius,r = 2 cm

Instant length,l = 9cm

The radius of the cylinder decreases.

Volume of cylinder =

[tex]V =\pi r^2l[/tex]

Since the volume of the cylinder does not changes, we can write:

[tex]\dfrac{dV}{dt}=0[/tex]

Rate of change of volume:

[tex]\dfrac{dV}{dt} = \pi(2r\dfrac{dr}{dt}l + r^2\dfrac{dl}{dt})[/tex]

Puttiung values, we get

[tex]0 = \pi(2(2)\dfrac{dr}{dt}(9) + (2)^2(0.7))\\\\\dfrac{dr}{dt}=-\dfrac{4\times 0.7}{4\times 9} \approx -0.78[/tex]

Thus, the radius is decreatsing at a rate 0.78 cm per second.

Using differentiation, it is found that the radius is increasing at a rate of 0.35 cm/second.

The length of a cylinder is the diameter, which is double the radius, hence:

[tex]l = 2r \rightarrow r = \frac{l}{2}[/tex]

Applying differentiation, the rate of change of the radius is given by:

[tex]\frac{dr}{dt} = \frac{1}{2}\frac{dl}{dt}[/tex]

We are given that the rate of change of the length is [tex]\frac{dl}{dt} = 0.7[/tex], hence:

[tex]\frac{dr}{dt} = \frac{1}{2}\frac{dl}{dt} = \frac{1}{2}(0.7) = 0.35[/tex]

The radius is increasing at a rate of 0.35 cm/second.

Answer:

1 small bags and 5 large bags

Step-by-step explanation:

In this case we can solve it using a 2x2 system of equations, like this:

let x: number of small bag

let y: number of large bag

So:

5 * x + 8 * y = 45

x + y = 6 => x = 6 - y

Replacing, we are left with that:

5 * ( 6 - y) + 8 * y = 45

30 - 5 * y + 8 * y = 45

- 5 * y + 8 * y = 45 - 30

3 * y = 15

y = 15/3

y = 5

Now to calculate x:

x = 6 - 5

x = 1

this means that 1 small bag and 5 large bags

Answer:

he bought 1 bag of small apple and 5 bags of Large apple

Step-by-step explanation: given that A small bag of apples = $5 and

A large bag = $8.

If you bought 6 bags and spent $45,

Let number of small apple be S

And large Apple be L

L + S = 6 ....... (1) ×8

8L + 5S = 45 .......(2)

Solve equation 1 and 2 simultaneously

8L + 8S = 48

8L + 5S = 45

Eliminate L

3S = 3

S = 1

Substitute S in equation 1

L = 6 - 1 = 5

Therefore, he bought 1 bag of small apple and 5 bags of Large apple

Answer: One book has a greater mass.

Step-by-step explanation:

Jamal has a pair of shoes with a total mass of 960 grams. This means that each shoe has a mass of:

960 grams ÷ 2= 480 grams per shoe.

Jamal also has four identical books with a total mass of 2 kilograms. Note that 1000 grams make a kilograms. Therefore 2 kilograms will be (2 × 1000 grams) = 2000 grams.

Each book will have a mass of:

2000 ÷ 4 = 500 grams per book.

One shoe has a mass of 960 divided 2 = 480 grams . One book has a mass of 2000 divided 4 = 500 grams . So one book has a greater mass.

Answer: x - 4 = 9  (x will equal 13)

What I did was since 4 is less than 13 we could use 13-4 since 4 is less than 13.

The null hypothesis was not rejected at 1% and 5% level of significance, but was rejected at 10% level of significance.

Step-by-step explanation:

The complaints made by the customers of a bottling company is that their bottles are not holding enough liquid.

The company wants to test the claim.

Let the mean amount of liquid that the bottles are said to hold be, μ₀.

The hypothesis for this test can be defined as follows:

H₀: The mean amount of liquid that the bottles can hold is μ₀, i.e. μ = μ₀.

Hₐ: The mean amount of liquid that the bottles can hold is less than  μ₀, i.e. μ < μ₀.

The p-value of the test is, p = 0.054.

Decision rule:

The null hypothesis will be rejected if the p-value of the test is less than the significance level. And vice-versa.

        The p-value = 0.054 > α = 0.01.

        The null hypothesis was failed to be rejected at 1% level of

        significance. Concluding that the mean amount of liquid that the

         bottles can hold is μ₀.

        The p-value = 0.054 > α = 0.05.

        The null hypothesis was failed to be rejected at 5% level of

        significance. Concluding that the mean amount of liquid that the

         bottles can hold is μ₀.

        The p-value = 0.054 < α = 0.10.

        The null hypothesis will be rejected at 10% level of

        significance. Concluding that the mean amount of liquid that the

         bottles can hold is less than μ₀.

Question:

Which of these is not a property of the renal counter-current multiplier?

It is opposed by the vasa recta.

It exploits the structure of the nephron loop.

It depends on active ion transport to function.

It creates a hyperosmotic interstitial fluid in the kidney medulla.

Answer:

The correct option is;

It is opposed by the vasa recta

Step-by-step explanation:

Counter current multiplication is the process whereby energy is used to build osmotic pressure gradient in the kidney such that water is reabsorbed from the exit tubular fluids reducing the volume of produced urine by increasing the urine concentration while the vasa recta capillaries slows blood flow rate so as to keep the osmotic pressure gradient constant enabling water to be reabsorbed thus concentrating the urine in line with counter current multiplication.

Final answer:

The square root of 685 lies between 26 and 27. To the nearest integer, the estimate is 26, and to the nearest tenth, the estimate is 26.2, given that it is roughly 9/53 of the way from 26 to 27.

Explanation:

To estimate the square root of 685 to the nearest integer and tenth, we have to determine which two perfect squares it lies between. The perfect square closer to 685 without going over is 676 (√676 is 26), and the next perfect square is 729 (√729 is 27). Thus, the square root of 685 lies between 26 and 27.

To estimate to the nearest integer, we would round √685 to 26, as it's closer to 676. For the nearest tenth, we need to see how much 685 exceeds 676. It exceeds by 9, and since 729-676 is 53, 685 is roughly 9/53 of the way from 26 to 27. So, a quick estimation for √685 to the nearest tenth could be 26 + (9/53)*1 which is approximately 26.2. Therefore, the estimated value of the surd √685 to the nearest tenth would be 26.2.

Answer:

Hence Perimeter for  new rectangle will be 27 units .

Step-by-step explanation:

Given:

A rectangle with enlarged factor of 1.5

L=7 and W=2

To Find:

Perimeter for new rectangle

Solution:

First calculate the new dimensions for new rectangle ,

Given that original length and width as 7 and 2 respectively and it is increasing by 1.5 times of the original ones

So

New length =1.5 *L

=1.5 *7

=10.5 units

And for width,

New width=1.5 *W

=1.5 *2

=3

Hence New dimensions are 10.5 and 3 units .

So perimeter of new rectangle =2(New length + New breadth)

=2(10.5+3)

=2(13.5)

=27 units

P(blue and green) = P(blue)*P(green) = (5/8)(2/8) = 10/64

The probability that the first ball is blue and the second is green, with no replacement, is approximately 0.179 or 17.9%.

The subject of this question pertains to probability, specifically the concept of dependent events in the realm of combinatorics. The problem involves an urn with 8 balls of different colors. The question asks us to find the probability that a blue ball is drawn first and a green ball second, with no replacement.

Firstly, we calculate the individual probabilities. The probability of drawing a blue ball first is 5/8, because there are 5 blue balls out of a total of 8. Since the blue ball isn't replaced, there are now 7 balls left in the urn, and therefore, the probability of drawing a green ball next is 2/7. To find the combined probability, we multiply the individual probabilities: (5/8) * (2/7) = 10/56 = 0.1786 (rounded). So the probability that the first ball is blue and the second is green is approximately 0.179 or 17.9%.

Median = 102

Step-by-step explanation:

To find the median we will following the steps below;

study the numbers, if they are not arrange from ascending to descending order, you try to do that.

87,98,106,82,111,120

82, 87, 98,106, 111, 120

Pick the middle number, if there is just one number that falls in the middle, that number is your median, but if there two numbers that falls in the middle, you add the two numbers and then divide by 2.

In this case, two numbers falls in the middle, so we will add and divide by 2

That is;

Median = 98 + 106   /2

              =204 /2

               =102

Answer:

  5.7 cm or 2 1/4 in

Step-by-step explanation:

Your tape measure is not shown.

  On my tape measure, 5.7 cm is the closest mark. On the inch scale, 2 1/4 inches is the next-closest mark.

_____

On a tape measure graduated in 1/32 inch between 2 and 3 inches, you can find the closest mark by rounding to the nearest 32nd:

  2.23607 × 32 ≈ 71.55 ≈ 72 --- 32nds of an inch

  72/32 = 2 1/4 . . . . the closest mark on an inch ruler graduated in 32nds

__

For a ruler graduated in millimeters, you can find the closest millimeter in the same way. There are 25.4 mm to the inch.

  2.23607 in × 25.4 mm/in ≈ 56.80 mm ≈ 57 mm

  57 mm = 5.7 cm . . . closest mark on metric scale

__

When we check the error, we find the metric mark is closer than the inch mark.

  5.7 cm ≈ 2.24409 in . . . . error of 0.00802 in

  2 1/2 in = 2.25000 in . . . error of 0.01393 in

Final answer:

The mark on the tape measure closest to 2.23607 inches is just above 2 3/16 inches, which can be more precisely measured with a tape measure that features millimeter or half-millimeter markings.

Explanation:

The student has asked which mark on the tape measure is closest to 2.23607 inches. To answer this question, we must consider the precision of the measuring device. When using a ruler without millimeter markings, such as the bottom ruler mentioned, the measurement can be understood in tenths of a centimeter. This would make it difficult to conclusively measure and report on the hundredths digit for a length.

Conversely, using a tape measure with millimeter or even half-millimeter markings (akin to the top ruler), the user can measure more precisely. Given that 1 inch equals 2.54 centimeters, 2.23607 inches would be approximately 5.679818 centimeters. This would be between the 2.5 cm and 2.6 cm marks on a metric tape measure or between 2 3/16 inches and 2 1/4 inches on an imperial tape measure; 2.23607 inches is very close to, but slightly above, 2 3/16 inches, so this would be the mark on an imperial tape measure that is closest to 2.23607 inches.

Answer:

In 2.4 minutes the fan made 105.5 revolutions.

Step-by-step explanation:

In order to solve this problem we need to convert the speed from radians to revolutions. To do that we can use a rule of three as shown below:

2pi rad/s -> 1 rev/s

4.6 rad/s -> x rev/s

2pi/4.6 = 1/x

2pix = 4.6

x = 4.6/2pi = 2.3/pi rev/s

Now we need to conver the time at which the blade was spinning from minutes to seconds, to do that we need to multiply by 60.

t = 2.4*60 = 144 s

To calculate the number of revolutions we multiply the angular velocity of the fan by the time it was spinning:

rev = (2.3/pi)*144 = 331.2/pi = 105.5 revolutions

Answer:

105.4 revolutions

Step-by-step explanation:

By converting 2.4 min into seconds, we'll have

2.4 minutes = 60 x 2.4 = 144 seconds.  

Now, in 2.4 minutes, the fan rotate 4.6 [rad/s] x 144s = 662.4 radians

As the answer is required in revolution

therefore, 1 radian = 0.159155 revolutions

so  0.159155 x 662.4 = 105.4 revolutions

The fan rotated 105.4 revolutions in 2.4 minutes

0.7579 is the best point for the proportion of students at the college who have completed their required English 101 course.

Step-by-step explanation:

"The proportion is written in the fraction form as required number in the numerator and the total number in the denominator."

Here, the 95 students at a college were asked whether they had completed their required English 101 course.

So, the total students = 95

It is given that, 72 students said "yes".

So, the number of completed students = 72

To estimate the best point for the proportion of students who completed their  English 101 course :

Now, the numerator is the no.of students who have completed their required English 101 course.

Proportion = 72 / 95

⇒ the best point is calculated as 72 divided by 95

⇒ 0.7579 (round to four decimal places).
