What is the ratio of quarters to nickels in a dollar
sleet_krkn [62]

For quarters we have:

0.25x = 1

Where,

x: number of quarters

Clearing x we have:

x = \frac{1}{0.25}\\x = 4


For nickels we have:

0.05y = 1

Where,

y: number of nickels

Clearing y we have:

y = \frac{1}{0.05}\\y = 20


Then, the ratio of quarters to nickels is:

\frac{x}{y}= \frac{4}{20}

Simplifying we have:

\frac{x}{y} = \frac{1}{5}


Answer:

The ratio of quarters to nickels in a dollar is:

\frac{x}{y}= \frac{1}{5}

Answer:

<em><u>A:</u></em>

<em><u>Square</u></em>

<em><u>Rectangle</u></em>

<em><u>Parallelogram</u></em>

<em><u>Quadrilateral</u></em>

<em><u>Rhombus</u></em>

<em><u></u></em>

<em><u></u></em>

Step-by-step explanation:

All sides and angles are equal so it is a square

All angles are 90 degrees so it is a rectangle (eliminate C)

Opposing angles and side lengths are congruent so it is a parallelogram (eliminate D)

It has 4 sides so it is a quadrilateral (eliminate B)

Since all of the other answers are eliminated you don't necessarily need to prove that is is a rhombus, but it is good practice.

Opposing sides are congruent so it is a rhombus.
