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

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.

  3)  (0, 0)

  4)  (-1, 2)

Step-by-step explanation:

I find a graphing calculator provides a quick solution to a system of linear equations.

3) The solution is (x, y) = (0, 0)

4) The solution is (x, y) = (-1, 2)

__

In each case, the y-term can be eliminated by multiplying the first equation by 3. For problem 3) the resulting equations must be added. For problem 4), the resulting equations must be subtracted.

Answer:

87.5 by 70 inches

Step-by-step explanation:

No options were given. So, I will calculate the minimum width

Given

[tex]Original\ Logo = 4.5 : 3.6[/tex]

Height = 70 in ---- of the printed logo

Required

Determine the dimension that keeps the requirement

Let x be the width of the printed logo.

So, the ratio can be represented as:

[tex]Printed\ Logo = x : 70[/tex]

Equate both ratios

[tex]x : 70 = 4.5 : 3.6[/tex]

As fraction

[tex]x / 70 = 4.5 / 3.6[/tex]

Multiply through by 70

[tex]70 * x / 70 = 4.5 / 3.6* 70[/tex]

[tex]x = 87.5[/tex]

So, one of the dimension that meets the requirement is a width of 87.5 inches
