Chuin has 18 coins in his pocket. He has nickels and dimes that total $1.45. How many nickels and how many dimes does he have? Write and solve a system of equations to find the answer.
A. 10 Nickles, 8 dimes
B. 9 nickles, 9 dimes
C. 8 nickles, 10 dimes
D. 7 nickles, 11 dimes
Answer:
D
Step-by-step explanation:
Let n represent the number of nickels and d represent the number of dimes Chuin has.
Since Chuin has a total of 18 coins in his pocket, the sum of the number of nickels and dimes must total 18. So:
[tex]n+d=18[/tex]
The total worth of the coins is $1.45. Since each nickel is worth $0.05 and each dime is worth $0.10:
[tex]0.05n+0.1d=1.45[/tex]
Solve the system. We can use elimination (you can use substitution if you prefer, it works just as perfect!). First, multiply both sides of the second equation by 10:
[tex]0.5n+d=14.5[/tex]
Next, we can multiply the first equation by negative one:
[tex]-n-d=-18[/tex]
Add the two equations together:
[tex](0.5n+d)+(-n-d)=(14.5)+(-18)[/tex]
Simplify:
[tex]-0.5n=-3.5[/tex]
Divide both sides by -0.5. So:
[tex]n=7[/tex]
Chuin has seven nickels.
Using the first equation again, substitute n for 7 and solve for d:
[tex](7)+d=18\Rightarrow d=11[/tex]
Therefore, Chuin has seven nickels and 11 dimes.
Our answer is D.

Can you plzz find the width...and give steps
Answer:
12
Step-by-step explanation:
We know that Tyler's chest has a length of 30 inches, width of 16, and a height of 24 inches. To find the volume of the chest, multiply the length by width by height: 24*30*16 = 11,520 in^3 The volume is 11,520.
Juliet's chest will Have a length of 40 inches and the same height as Tyler's chest, or 24 inches. It also has the same volume of Tyler's chest, or 11,520
So Tyler's chest is 24 by 30 by 16 inches, and is 11,520 inches^3
Juliet's chest will be 40 by ? by 24 inches, and will be 11,520 inches^2.
We have to find the width of Juliet's chest. To do that, we have to divide the length times height of Juliet's chest by The volume of her chest, or
11,520/(40*24) = 11,520/960 = 12
Her chest is 12 inches wide
The average number of employees that call in sick for the day over the course of a year is 25. The number of employees that call in sick on 12 days are 25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28 , and 14 Enter the sample mean and the population mean.
Answer:
it depends on the work place to play it safe i would choose 12
Step-by-step explanation:
The sample mean is equal to 24 and population mean is equal to 25
What is sample mean?Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.
Sample mean= sum of the terms/number of the terms
What is population?
The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.
Population mean= sum of the population/ number of the population
From the given question average of entire year is 25.
According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.
According to the sample mean formula,
sample mean= sum of the terms / number of the terms
⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24
Thus the sample mean is equal to 24 and population mean is equal to 25

1/4 is larger than 5/8 by how much?
( fraction)
Answer:
3/8
Step-by-step explanation:
Step 1: Multiply the denominator and the numerator of 1/4 by 2 to get a common denominator between the two. (1/4 and 5/8 is now 2/8 and 5/8)
1*2= 2; 4*2= 8, so you get 2/8 (which is equal to 1/4)
Step 2: When you get 2/8, subtract:
5/8 - 2/8 = 3/8
And... since 2/8 is equal to 1/4, 3/8 is the answer :)
Hope this helps :)
