Answer:

48 inches

or

0.8 minutes

Step-by-step explanation:

To find the unit rate of inches per hour, divide 144 by 3.

144÷3=48

You don't need to round because there are no decimals.

To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour).

3×60=180

Then divide 144 by 180.

144÷180= 0.8

You don't need to round because there are no thousandths.

There are many examples to pick from, but one example is this:

The set of rational numbers (aka any fraction of two integers) is closed under the operation of division. Divide any two rational numbers and we get some other rational number.

However, the set of integers is not closed under division. If we divided 10 over 3, then we get 10/3 = 3.333 approximately which isn't an integer. So just because the set of integers is a subset of the rationals, it doesn't mean that the idea of closure follows suit from superset to subset.  

Side note: The term "superset" is basically the reverse of a subset. If A is a subset of B, then B is a superset of A.

Answer:

Step-by-step explanation:

Doing this the long way, write a^12 as a product of "a"s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

Now group them into groups of 4

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube

Now do the same thing with groups of 6s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

a^12 = (a^6)^2

So the two answers are

Perfect cube:  [(a^4)]^3

Perfect square: (a^6)^2

   To solve this problem use the property of similar triangles,

 "Corresponding sides of the similar triangles are proportional"

By using this property, height of the parasailer is 160 feet.

From the figure attached,

Let the height (PQ) of the parasailer = x ft

Height of the parasailer AB = 25 ft.

And the length of the rope AC = 2.5 ft.

Since, both the triangles ΔABC and ΔPQR are the similar triangles, their corresponding sides will be proportional.

[tex]\frac{AB}{PQ}=\frac{AC}{PR}[/tex]

[tex]\frac{2}{x} =\frac{2.5}{200}[/tex]

[tex]x=\frac{200\times 2}{2.5}[/tex]

[tex]x=160[/tex] ft

        Therefore, height of the parasailer is 160 feet.

The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.

Both concepts are fundamental in arithmetic and algebraic calculations.

In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:

1. **Unknown Factor:**

  - An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.

  - In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.

  - For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."

2. **Quotients:**

  - "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.

  - In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).

  - For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.

  - Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.

Answer:

[tex]\displaystyle \frac{ 1 }{3} [/tex]

Step-by-step explanation:

we would like to compute the following limit:

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} [/tex]

if we compute the limit from numerator to denominator directly,we'd end up with

[tex] \dfrac{ \infty }{ \infty } [/tex]

which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{ {n}^{2} ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]

remember that ,

thus we acquire:

[tex]\displaystyle \lim_{n \to \infty } \frac{ {n} \sqrt{ ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]

reduce fraction:

[tex]\displaystyle \lim_{n \to \infty } \frac{ {} \sqrt{ 4 {}^{} + \frac{3}{n} } }{6} [/tex]

as n approaches to ∞ ,3/n approaches to 0 which yields:

[tex]\displaystyle \frac{ \sqrt{ 4 {}^{} } }{6} [/tex]

simplify square root:

[tex]\displaystyle \frac{ 2 }{6} [/tex]

reduce fraction:

[tex]\displaystyle \frac{ 1 }{3} [/tex]

hence,

[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} = \boxed{ \frac{1}{3} }[/tex]

Answer:

Step-by-step explanation:

Let the salary in the previous year = $ x

Now the salary = $ (x +1000)

This year savings = $ 5720

13% * (x + 1000)= 5720

0.13 *(x + 1000) = 5720

0.13*x + 0.13*1000 = 5720

0.13x + 130 = 5720        {subtract 130 from both sides}

         0.13x = 5720 - 130

        0.13x  = 5590    {Divide both sides by 0.13}

               x = 5590/0.13

x = $ 43000
