A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split. In this situation, in a simple fraction, the numerator as well as the denominator are both integers.

Fractions help to distribute and judge the numbers easily and make the calculation faster. Instead of using decimal values, the representation of fractions looks simpler.

Jia's mom = 1/4

Jia's sister = 1/4

Jia's brother = 1/4

Jia's share = 1 - (1/4 + 1/4 + 1/4) = 1 - 3/4 = 1/4( of her share)

Jia's share in relation to the whole = 8/8 - 7/8 = 1/8

The three-digit palindromes that can be created using the digits are 16 numbers.

A word, number, phrase, or other group of characters that reads the same backwards as it does forwards is called a palindrome. Examples include the words "madam" or "racecar," the date and time 12/21/33 12:21, and the phrase "A man, a plan, a canal — Panama."

The three-digit palindromes are of the form: ABA.

Here, A can be selected in 4 ways.

Digits can be repeated hence, B can be selected in 4 ways.

The last A is the same number as the first A, hence the selection is 1 way.

The number of three digits palindrome that we can form is:

(4)(4)(1) = 16 ways

Hence, the three-digit palindromes that can be created using the digits are 16 numbers.

The simple interest on a principal amount is the function on time t.

Simple interest is an interest charge that borrowers pay lenders for a loan. It is calculated using the principal only and does not include compounding interest. Simple interest relates not just to certain loans. It's also the type of interest that banks pay customers on their savings accounts.

Given here: Principal=$3200, Annual rate of interest =8% and time=5 years

Thus Simple interest is S.I= 3200×8×5 / 100

                                           =$1280

Which is equal to the interest given in the question.

Thus the the interest rate forms a linear function or

Step-by-step explanation:

The answer to the expression 2b x b is simply 2b^2. Exponentiation is a mathematical operation that raises a number to a power, and in this case, b is raised to the power of 2.

Alternatively, if exponentiation is not allowed, the answer to the expression is simply 2b * b, which can be simplified to 2b^2 as well.

So, the answer to the expression 2b x b is 2b^2, regardless of whether or not exponentiation is used.

The expression 2b x b represents the product of two scalars, 2 and b, multiplied by a scalar b.

The expression could represent a variety of quantities in mathematics and science, including the area of a rectangle, the volume of a cube, or the kinetic energy of an object, among others.

Using the graph of the function, the value of f(4) is 6.

A function is an expression that shows the relationship between the independent variable and the dependent variable.  A function is usually denoted by letters such as f, g, etc.

The set of inputs is called the domain of the function, and the set of outputs is called the codomain. A function maps each input to exactly one output, so it is also sometimes referred to as a mapping.

Using the graph, the value of f(4) can be found by checking for the value y when x = 4. Check the attached image.

15% of the students scored higher than Henry on the accounting exam.

Percentiles are a measure of the relative standing of a value within a set of values. The nth percentile is a value such that n% of the values are less than or equal to that value.

So, if Henry's score is in the 85th percentile, it means that 85% of the scores in the class are less than or equal to his score.

Therefore, 100% - 85% = 15% of the scores in the class are higher than Henry's score. So, 15% of the students scored higher than Henry on the accounting exam.

Step-by-step explanation:

Hope this helps : )

The required solution of the given equation is x = -7.

"Multi-step equation" means an equation that requires more than one step to be solved.

"Like terms" refers to terms that have the same variables raised to the same powers. In this equation, there are no like terms, so no simplification of the equation is needed in that regard.

"Negative coefficients" refers to the fact that some of the coefficients in front of the variables in the equation are negative. For example, in this equation, the coefficient of x is -3, and the coefficient of -9 is also negative.

To solve this equation, you can simplify both sides by combining like terms:

-9 + x -3x = 5

-9 - 3x + x = 5

-9 - 2x = 5

Next, isolate the variable on one side of the equation by adding 9 to both sides:

-9 - 2x + 9 = 5 + 9

-2x = 14

Finally, divide both sides by -2 to find x:

(-2x) / -2 = 14 / -2

x = -7

So the solution is x = -7.

Answer:

The answer is the equation for the function describing the movement of the buoy:

f(x) = 5 * sin(2 * pi * x / 16) + 8

Step-by-step explanation:

To graph the function, we need to find an equation that describes the buoy's movement. Since the buoy bobs up and down 5 meters from the ocean's depth, we can use the sine function. The amplitude of the function is 5, since the buoy moves 5 meters from the normal ocean depth. The period of the function is 16 seconds, since it takes 16 seconds for the buoy to go from its highest point to its lowest point.

Using this information, we can write the equation for the function as:

f(x) = 5 * sin(2 * pi * x / 16) + 8

where x is the time in seconds.

The first point on the graph would be (0, 8), since at x = 0 the buoy is at normal ocean depth. The second point would be either a maximum or minimum value on the graph closest to x = 0, which can be found by finding the derivative of the function and setting it equal to zero.

The graph of the function would look like a wave that oscillates up and down, with a maximum value of 5 meters above the normal ocean depth and a minimum value of 3 meters below the normal ocean depth.
