Fifteen is 30% of what number

Explanation:

Let the side of a square be represented as "x".

The perimeter of a square is the sum of it's sides. Since the sides are equal, we can add x four times to get the perimeter.

[tex]\rightarrowtail \text{Perimeter of square} = 4 \times x[/tex]

[tex]\rightarrowtail \text{Perimeter of square} = x + x + x + x[/tex]

[tex]\rightarrowtail \boxed{\text{Perimeter of square} = 4x}[/tex]

To find the perimeter of the square, simply substitute the side length of the square into 4(Side length) to find the perimeter.

The expression 5⁻¹³× 5⁵ × 2⁵ can be rewritten as 5⁻⁸ × 2⁵.

Exponentiation is the method of writing a number in terms of powers. This method is usually useful for writing larger numbers in an understandable and effective way.

For a number x, suppose x can be written as aᵇ, here 'a' is called the base and 'b' is called the exponent.

We have to write the expression 5⁻¹³× 5⁵ × 2⁵ in a form where each base comes only once.

This can be solved using one of the basic property of exponents as stated below:

xᵃ × xᵇ = xᵃ⁺ᵇ

That is, upon multiplying two exponents with the same base value, we can combine it and add the exponent values.

∴ 5⁻¹³× 5⁵ can be rewritten as 5⁻⁸.

So 5⁻¹³× 5⁵ × 2⁵ =  5⁻⁸ × 2⁵.

Hence the expression 5⁻¹³× 5⁵ × 2⁵ can be rewritten as  5⁻⁸ × 2⁵ where each base comes only once.

The linear equation is given by y = 15x. A person earns $600 for working 40 hours

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

The line passes through (7, 105) and (8, 120), hence:

y - 105 = [(120 - 105)/(8-7)}(x - 7)

y = 15x

For 40 hours:

y = 15(40) = $600

if the person got a $50 bonus and also worked some hours, it would change the graph

Considering the given linear function, variable x represents the number of hours since the bowl was filled.

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

In this problem, the number of ounces of water left in the bown after x hours is given by:

y = -0.5x + 4.

Variable x is the input, hence, it represents the number of hours since the bowl was filled.

More can be learned about linear functions at https://brainly.com/question/24808124

Answer:

Part A: The number of ounces of water left in the bowl depends on the number of hours since the bowl was filled. So the number of ounces is the dependent quantity. The y-variable represents the dependent quantity. So, the y-variable represents the ounces of water left in the bowl.

Part B: The number of hours since the bowl was filled is the independent quantity. The x-variable represents an independent quantity. So, the x-variable represents the number of hours since the bowl was filled.

Part C: The value 4 is the initial value of the function. It represents the ounces of water in the bowl immediately after the bowl was filled and before the cat drank any water from the bowl.

Part D: The value -1/2 is the function’s rate of change. It represents the change in ounces of water in the bowl with every hour.

Answer:

-4 ≤ y <∞.

Step-by-step explanation:

y = 3x² - 18x + 23

= 3(x² - 6x) + 23

= 3(x² - 6x + 9) - 27 + 23

= 3(x - 3)² - 4 ≥ -4

So the range is -4 ≤ y <∞.

Step-by-step explanation:

The value of function (f/g)(x) is 3√4x/2x+3 , where x ≠ -3/2.

What is Function?

A relation between a set of inputs having one output each is called a function.

The functions are given as;

f(x) = 3√4x

g(x) = 2x + 3

Now, We are to find the value of function (f/g)(x) as;

(f/g)(x) = f(x)/g(x)

(f/g)(x) = 3√4x/2x+3

Hence, The value of function (f/g)(x) is 3√4x/2x+3

And, Restriction of the function occurs at the point where the denominator is zero.

Hence,

2x + 3 = 0

2x = -3

x = -3/2

So, The required function (f/g)(x) is 3√4x/2x+3 , where x ≠ -3/2.
