The concept of density explains  how tightly packed together  the matter in an object is

The density of a material is a measure of how tightly packed matter is together.

The concept of density compares the quantity of matter the material has to its volume. A material with much matter in a certain volume has a high density.

An object with high density is considered highly dense or heavy and an object with low density is considered less dense. For example, the air is about 830 times less dense than water.

Step-by-step explanation:

1% of 10 inch is 0.1 inch

10 inch + 0.1 inch = 10.1 inch

10 inch - 0.1 inch = 9.9 inch

V = s³

For s = 9.9 in., V = (9.9 in.)³ = 970.299 in.³

For s = 10.1 in., V = (10.1 in.)³ = 1030.301 in.³

For 10 in., V = (10 in.)³ = 1000 in.³

|1000 in.³ - 970.299 in.³| = 29.701 in.³

|1000 in.³ - 1030.301 in.³| = 30.301 in.³

Part B: Three possible initial investments to reach the goal of having a future value of $12,000 in 5 years are:

Part C: The total interest earned on each investment is as follows:

The total interest for investment 1 is a product of simple interest formula, which multiplies the principal, interest rate, and time.

The total interests for investments 2 and 3 are the results of the online finance calculator., which inputs the future value, compound interest rate, and compounding period.

Future value = $12,000

Answer:

\(\displaystyle \cos(\theta) = \frac{\sqrt{7}}{4}\).

\(\displaystyle \tan(\theta) = \frac{3\sqrt{7}}{7}\).

Step-by-step explanation:

By the Pythagorean identity, for any given angle \(\theta\), \(\sin^{2}(\theta) + \cos^{2}(\theta) = 1\).

Given that \(\displaystyle \sin(\theta) = 3/4\), solve this equation for \(\cos(\theta)\).

\((\sin(\theta))^{2} + (\cos(\theta))^{2} = 1\).

\(\displaystyle \left(\frac{3}{4}\right)^{2} + (\cos(\theta))^{2} = 1\).

\(\begin{aligned} \cos(\theta) &= \sqrt{1 - \frac{9}{16}} \\ &= \sqrt{\frac{7}{16}} \\ &= \frac{\sqrt{7}}{4} \end{aligned}\).

The tangent of an angle is equal to the ratio between the sine and cosine of that angle. In this question:

\(\begin{aligned} \tan(\theta) &= \frac{\sin(\theta)}{\cos(\theta)} \\ &= \frac{3/4}{\sqrt{7}/4} \\ &= \frac{3}{\sqrt{7}} \\ &= \frac{3\sqrt{7}}{7}\end{aligned}\).

If we have \(35+k\), we can assume that k is around 10.

So \(35+10=45\).

Now let's decrease k by 1, making k=9.

We can see that the value is decreasing, but let's try one more.

Let's make k=8.

\(35+8=43\)

The given Mayan number which is : :|| :|| in decimal (base 10) is 42.

The Mayan number system is a base-20 system that uses three symbols: a dot (.), a horizontal bar (|), and a shell-like symbol (:). The symbol for zero is a shell-like symbol (:).

To convert the given Mayan number to decimal (base 10), we need to understand the positional value of each symbol. Each position in the number represents a power of 20, with the rightmost position being 20⁰, the next position to the left being 20¹, and so on.

The Mayan number given, : :|| :||, can be broken down as follows:

The leftmost position has no symbol, which represents a value of 0.

The second position from the left has two shell-like symbols (:), which represents a value of 2x20¹ = 40.

The third position from the left has two horizontal bars (||), which represents a value of 2x20⁰ = 2.

The given Mayan number in decimal (base 10) is 40 + 2 = 42.

The percentage of the data values are between 110 and 170 = 37.5%

We know that in the box plot, the first quartile is nothing but 25% from smallest to largest of data values.

The second quartile is nothing but between 25.1% and 50% (i.e., till median)

The third quartile: 51% to 75% (above the median)

And the fourth quartile: 25% of largest numbers.

In the attached box plot, we can observe that between two numbers on the number line there are 5 equal parts.

So, each unit length measures 10 units.

Also, the median of the data = 110

We need to find the percentage of the data values are between 110 and 170.

i.e., the percentage of the data values are in the third quartile.

The range of this box plot is: 190 - 30 = 160

The data values are between 110 and 170 = 60

Using percentage formula,

P = (60/160) × 100

P = 37.5%

1.111 liters of water must be added to 5 kilograms of soil.

According to the statement, water percentage is equal to the ratio of water mass divided by the total mass of water and dust and multiplied by 100. Then, the initial and final percentages are defined below:

Initial percentage

y / 5 = 0.12                              (1)

Final percentage

(y + x) / (5 + x) = 0.28             (2)

Then, we need to resolve the resulting system of linear equations:

y = 0.6                  (1)

y + x = 1.4 + 0.28 · x

0.72 · x = 1.4 - y

x = 1.944 - 1.389 · y

x = 1.111

We need to add 1.111 kilograms of water. If the density of a kilogram per liter, the volume required in liters is:

V = (1.111 kg) / (1 kg / L)

V = 1.111 L

The two expressions are not equivalent.

To simplify the expression (p^2n^1/2)^0 √ p^5n^4, we first need to understand the properties of exponents and radicals.

Recall that any number raised to the power of zero is equal to 1, so (p^2n^1/2)^0 = 1.

Next, we can simplify the radical term by multiplying the exponents inside and outside the radical:

√ p^5n^4 =

(p^5n^4)^(1/2)

= p^(5/2)n^(4/2)

= p^(5/2)n^2

Combining this result with the previous step, we have:

(p^2n^1/2)^0 √ p^5n^4

= 1 * p^(5/2)n^2

= p^(5/2)n^2

This is not equivalent to p^18n^6 √p. In fact, p^(5/2)n^2 cannot be simplified any further without additional information about the expression.  ,
