Answer:

$551.25

Step-by-step explanation:

1. Encuentre el 25% de $735:

0.25 x 735 = 183.75

2. Reste este número del precio original, $735:

735 - 183.75 = 551.25

The lady paid $551.25 after the 25% discount on merchandise.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a 25% discount is advertised on all merchandise. A lady bought a merchandise for $735.

Assume that she paid $x after the 25% discount. Then, we can write -

[x] = 735 - 25% of 735

[x] = 735 - (25/100) x 735

[x] = 735 - (1/4) x 735

[x] = 735(1 - 1/4)

[x] = 735 x 3/4

[x] = 551.25

Therefore, the lady paid $551.25 after the 25% discount on merchandise.

[Question in english -

In a store, a 25% discount is advertised on all merchandise. If a lady bought $735, how much did she pay after the discount?]

Answer:

[tex]2a - b -c[/tex]

Step-by-step explanation: We know that:

[tex]log_{2} 5 = a\\log_{2} 3 = b\\log_2 7 = c\\[/tex]

and we want:

[tex]log_2 \frac{25}{21}[/tex].

We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).

[tex]log_2 \frac{25}{21} = log_2 \frac{5^2}{3*7}.[/tex]

The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:

[tex]log_2 \frac{5^2}{3*7} = log_2(5)^2 - log_2 (3*7) = 2 log_2(5) - (log_2 3 + log_2 7)[/tex]

[tex]= 2 log_2(5) - log_2 3 - log_2 7[/tex] .

Substituting the variables:

[tex]2 log_2(5) - log_2 3 - log_2 7 = 2a - b - c[/tex]

Answer:

You are a Quadrilateral.

Step-by-step explanation:

The four sided shape that has four right angles and the whole sides are not equal to each other is a rectangle.

A rectangle is a quadrilateral. This simply means it has four sides.

The sides of a rectangle are not equal.

Therefore, the four sided shape that has four right angles and the whole sides are not equal to each other is a rectangle.

Answer:

One of the angles in the triangle might be 50.

AND

The length of the third side must be 11cm or smaller.

Step-by-step explanation:

-The triangle might be an equilateral triangle (having all the same sides and angles). False, since the triangle sum theorem states that all angles inside of a triangle must add up to 180, so an equilateral triangle would need to have all three angles at 60 degrees.

-One of the angles in the triangle must be 120 (false; it can be anything above 90, which is not only 120)

-The length of the third side must be 11cm or smaller. (True, Triangle Inequality Theorem)

-One of the angles in the triangle might be 50 (possibly, so very much true)

Answer:

f(k) = 2*k + 1

Step-by-step explanation:

The 'f' function takes the variable, doubles it, and then adds 1.

So f(k) = 2*k + 1

f(g) = 2*g + 1

f(m) = 2*m + 1, and so on

It doesn't really matter which variable you use, the function still does the same thing to it.

Answer:

[tex]f(x)=(x-3)(x^2+4x+8)[/tex]

Step-by-step explanation:

A polynomial function is given by the form:

[tex]f(x)=a(x-p)(x-q)...[/tex]

Where a is the leading coefficient, and p and q are the roots (more can be added if necessary).

Our zeros are 3 and (-2 + 2i).

And our leading coefficient a = 1.

Furthermore, by the Complex Root Theorem, if (-2 + 2i) is a zero, then (-2 - 2i) must also be a zero.

So, by substitution, we acquire:

[tex]f(x)=1(x-(3))(x-(-2+2i))(x-(-2-2i))[/tex]

Simplify:

[tex]f(x)=(x-3)(x+2-2i)(x+2+2i)[/tex]

Expand the second and third factors:

[tex]\begin{aligned} &=(x+2-2i)x+(x+2-2i)(2)+(x+2-2i)(2i)\\&= (x^2+2x-2ix)+(2x+4-4i)+(2ix+4i-4i^2)\\&=(x^2)+(2x+2x)+(-2ix+2ix)+(-4i+4i)+(4-4i^2)\\&=x^2+4x+(4+4)\\&=x^2+4x+8 \end{aligned}[/tex]

Therefore, our polynomial function of least degree and the given zeros will be:

[tex]f(x)=(x-3)(x^2+4x+8)[/tex]

Answer:73/500

Step-by-step explanation: To convert a percent to a fraction, write the percent as a fraction with a denominator of 100

This is gives us a complex fraction which can be simplified by writing the numerator as an improper fraction and then multiplying the improper fraction by 1/100

73/5×1/100=73/500

The fraction in lowest form is 73/500.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

The number is,

⇒ 14 3/5%

Now, Simplify the number in lowest term as;

⇒ 14 3/5%

⇒ 73/5%

⇒ 73/5 × 1/100

⇒ 73 / 500
