Julio has $2.75 in his pocket in nickels and dimes . The number of dimes is 10 less than twice the number of nickels. Find the n
Margaret [11]

Answer:

A dime is worth 2 nickels.  

let no of dimes be x

let no of nickles be y

so as per the data mentioned in the question , x=2*y-10

total amount = $2.75  

so total amount should comprise of nickels and dimes

x*dimes + y*nickels = $2.75

x*( 2 nickels)+ y *nickels = $2.75

=> nickles( 2x+y) = $ 2.75

but 20 nickels = 1 dollar

nickles(2x+y) = 2.75*20 nickels

cancelling nickles on both sides

2x+y = 55

already we know that x= 2y-10  

so 2(2y-10) +y= 55

4y-20+y=55

5y -20 =55

add 20 on both sides

5y-20+20=55+20

5y=75

divide with 5 on both sides

5y/5 =75/5

y= 15

so x= 2y-10  

x= 2*15-10  

x= 30-10

x= 20

so # of dimes =20  

# of nickels =15

Viefleur [7K]

Answer:

0.23

Step-by-step explanation:

You are given the table

\begin{array}{cccc}\text{Degree}&\text{Male}&\text{Female}&\text{Total}\\\text{Associate}&298&489&787\\\text{Bachelor}&685&916&1,601\\\text{Master}&260&397&657\\\text{Professional}&47&45&92\\\text{Doctorate}&32&35&67\\\text{Total}&1,322&1,882&3,204\end{array}

Form this table

Number of associate male students = 298

Total number of male students = 1,322

Relative frequency of male students earning an associate’s degree among all the males earning any degree =\dfrac{298}{1,322}\approx 0.23
