288pi units3

The volume of the cylinder in the image given is: 288pi units³.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

we know that,

Volume of a cylinder = πr²h,

where:

r = radius of the cylinder

h = height

Given the following:

r = 6 units

h = 8 units

Volume of the cylinder = 288pi units³

The length of section of pipe on the construction plan on conversion of units from feet to inches, 7 feet 5 1/8 inches will be 7.427 feet. On rounding off to the two places after decimal the length will be 7.43 feet.

We know that 1 foot = 12 inches. In order to convert feet into inches we'll multiply the given number by 12. Similarly to convert given inches to feet, we'll divide the given number by 12.

Here the length of pipe= 7 feet 5 1/8 inches

To convert 5 1/8 inches to feet: Divide by 12 {1 foot =12 inches}

                   =\(\frac{41}{8\\}\) ÷ 12

                   =\(\frac{41}{8}\) × \(\frac{1}{12\\}\)

5 1/8 inches =\(\frac{41}{96\\}\) feet

Now, 7 feet 5 1/8 inches = 7 feet + \(\frac{41}{96} \\\) feet

                                        = 7 feet + 0.4270 feet

                                        =7.4270 feet

                                        =7.43 feet

Answer:

  $11,715.65

Step-by-step explanation:

The applicable formula is ...

  FV = P(1 +r/n)^(nt)

where principal P earns interest at rate r compounded n times per year for t years.

  FV = $9500(1 +0.042/12)^(12·5) = $9500(1.0035^60) ≈ $11,715.65

The account will hold $11,715.65 after 5 years.

a) The initial deposit in the account is given as follows: 1,287.39 euros.

b) The interest rate of the account is given as follows: 3%.

The equation that gives the balance of an account after t years, considering simple interest, is modeled as follows:

A(t) = P(1 + rt).

In which the parameters of the equation are listed and explained as follows:

Considering the balances after 5 and 6 years, the interest rate is obtained as follows:

r = 1524.60/1480.50 - 1

r = 0.03.

Considering the balance after 5 years, the initial deposit is obtained as follows:

P(1 + 0.03 x 5) = 1480.5

P = 1480.5/1.15

P = 1,287.39 euros.

After 4 half-lives, only 1/16th (or 0.0625) of the initial amount of the radioactive isotope will remain.

The amount of a radioactive isotope remaining after a certain number of half-lives can be calculated using the formula:

Amount remaining = Initial amount × (1/2)^(number of half-lives)

In this case, we are given the initial amount as "grams" and we want to find out the amount remaining after 4 half-lives.

So, the equation becomes:

Amount remaining = Initial amount × (1/2)^4

Since each half-life reduces the quantity to half, (1/2)^4 represents the fraction of the initial amount that will remain after 4 half-lives.

Simplifying the equation:

Amount remaining = Initial amount × (1/16)

Therefore, after 4 half-lives, only 1/16th (or 0.0625) of the initial amount of the radioactive isotope will remain.

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

Starting with 42, there would be two branches of 2 and 21 connected to 42. Since 2 is prime, there are no more branches. Since 21 is composite, then two more branches are drawn of 3 and 7 connected to 21. Since 3 and 7 are prime, there are no more branches.

Therefore, the prime factorization of 42 is 2*3*7, and its factors would be 1,2,3,6,7,14,21,42.

Answer:

The range in which at least 88.9% of the data will reside, ($244,800, $295,200).

Step-by-step explanation:

The Chebyshev's theorem states that, if X is a random variable with mean µ and standard deviation σ then for any positive number k, we have  

\(P \{|X -\mu| < k\sigma\} \geq (1-\frac{1}{k^{2}})\)

Here \((1-\frac{1}{k^{2}}) = 0.889\).

Then the value of k is:

\(k = [\frac{1}{ 1-0.889}]^{1/2} = [\frac{1}{0.111}]^{1/2} = 3.0015\approx 3\)

Then we know that,

|X - µ| ≥ kσ

⇒ µ - kσ ≤ X ≤ µ + kσ.

Here it is given that mean (µ) = $270,000 and standard deviation (σ) = $8400.

Then, the price range is given by,

                     \(\mu - k\sigma \leq X \leq \mu + k\sigma\)

\(270000-(3\times 8400)\leq X\leq 270000+(3\times 8400)\)

                     \(244800\leq X\leq 295200\)

Thus, the range in which at least 88.9% of the data will reside, ($244,800, $295,200).

The number of books in the owner's office are 4.

Step-by-step explanation:

It is given that the book store had a new bookshelf that could hold 62 books the owner put 5 books on each of the shelves and the rest back in his office.

Now, let us assume the there are 'n' number of total books that the owner have with him;

=> total books = n

and the total books the shelf could hold is;

=> total books the shelf could hold = 62

Further, it is provided that the owner put 5 books on each of the shelves and the rest back in his office;

=> n = 62/5

=> n = 12.4

Therefore, the number of books in the owner's office are 4.

Step-by-step explanation:

First, we need to find the difference between the price that he sold the shares for and the price that he bought them at: (67.68-60.65) = 7.03

That means that there was a gain of $7.03 per share for Archie.

That being said, since Archie bought 100 shares, we can multiply that number by 100 to find the total gain from selling the shares:

(7.03x100)= 703

The answer then is:

Archie gained $703 from selling all of his shares.

  x = 9 inches

Step-by-step explanation:

You want the value of x in the similar triangles shown.

Corresponding sides are proportional. This means the ratio of the horizontal side of the triangle to the vertical side is the same for both.

  6/4 = (6+x)/10

  15 = 6 +x . . . . . . . . multiply by 10

  9 = x . . . . . . . . . subtract 6

The measure of x is 9 inches.

Additional comment

You could also write the proportion ...

  6/4 = x/(10 -4)

  x = 36/4 = 9 . . . . . . . multiply by 6

In the figure, there are two expressions used to give the side length to each square, as follows:

In a square, all the four side lengths have the same length, hence the value of x is obtained as follows:

6x - 1 = 4x + 6

2x = 7

x = 3.5 cm.

Then the side length of the square is obtained as follows:

The true expression about the account is D.) It is the sum of the initial amount and the additional amount after d days.

The answer is D because it represents the sum of the initial amount and the additional amount after d days. The initial amount is $10 and Owen adds $0.50 to the account each day for a number of days, represented by d.

By subtracting 1 from d, the expression ensures that on the first day (when d=1), only the initial $10 is counted. On each subsequent day, the additional amount of $0.50 is added to the total. Therefore, the expression 10+0.5(d−1) gives the amount of money in Owen's account after d days.

Step-by-step explanation:

The best first step would be to multiply the second equation by -2

then you would have the following

\(\ \ \ \ \ \ 4x - 5y = 2 \\-2*(2x)+ (-2)*y = (-2)*3\)

and when you multiply it is easy to eliminate because you will get

   \(4x - 5y = 2 \\-4x -2y = 6\)

and if you sum the equations you get

-7y = 8

so that is a single variable equation which is easier to solve.
