What is the ratio of quarters to nickels in a dollar

Mathematics

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:

5 : 1 is the ratio of quarters to nickels in a dollar.

Step-by-step explanation:

Using the conversion:

1 quarter = $0.25

1 nickel = $0.05

We have to find the ratio of quarter to nickels in a dollar.

\frac{\text{1 quarters}}{\text{1 nickel}}

Using conversion we have;

\frac{0.25}{0.05} = \frac{25}{5}

Simplify:

\frac{5}{1}

or

5 : 1

Therefore, the ratio of quarters to nickels in a dollar is, 5 : 1

In the United States the ages 13 to 55+ of smartphone users approximately follow a normal distribution with approximate mean and
andrezito [222]

Answer:

P ( 23 < X < 64.7 ) = P ( -1 < Z < 2 ) = 0.8186  

Step-by-step explanation:

Solution:

- Let X be a random variable that denotes the age of people who use smartphones.

- The random variable X follows a normal distribution with parameters mean (u) and standard deviation (s).

-The normal distribution can be expressed as:

                                        X~ N ( u , s^2 )

                                        X~ N ( 36.9 , 13.9^2 )

- The probability that a random smartphone user in the age range 13 to 55+ is between 23 and 64.7 years old can be expressed as:

                                        P ( 23 < X < 64.7 )

- We will compute the Z-score values for the interval:

       P ( 23 < X < 64.7 ) = P ( (x1 - u) / s < Z < (x2 - u) / s )

       P ( 23 < X < 64.7 ) = P ( (23 - 36.9) / 13.9 < Z < (64.7 - 36.9) / 13.9 )    

       P ( 23 < X < 64.7 ) = P ( -1 < Z < 2 )

- We will use Z-table to evaluate:

       P ( 23 < X < 64.7 ) = P ( -1 < Z < 2 ) = 0.8186

Which graph correctly represents the equation y=−4x−3?
pentagon [3]

Idk if u got the answer or not, but It's the last graph. Just by looking at it you can point two things out.

1. The y intercept is -3 (so the graph needs to have the point (0,-3) that takes out two options.)

2. The slope is negative. (Which means the graph is going to decrease. So that takes out the other two options that have it increased.)

A college student borrow $3,000 for 9 months to pay for a semester of school. If the interest is $185.63, find the monthly payme
photoshop1234 [79]

Total interest on the loan = 185.63

Total principal of the loan = 3,000

Total interest + principal = 3,000 + 185.63

Total future value of the loan = 3,185.63

The tenor of the loan = 9  months

Monthly payment = Total future value of loan/ number of months

Monthly payment = 3,185.63/9 = 353.9588

Monthly payment = $353.96 (Rounded to nearest cent)
