Quantity equation: t + s = 48kg
Copper equation: 23t + 79s = 44*48

Multiply the quantity equation by 23 to set the problem up for the elimination method. 

23t + 23s = 23*48
23t + 79s = 44*48

Subtract to solve for s. 

56s = 21*48
s = 18 [Number of 79% bars needed]
t = 48 - 18 = 30 [Number of 23% bars needed]

The equation of a line is -2x6y=-18. find the slope and the y-intercept. Then use them to graph the line.
Vaselesa [24]

Answer:

Slope=\frac{1}{3} and Y intercept=-3

Step-by-step explanation:

-2x + 6y = -18

Simplifying the equation,

6y = 2x - 18

y=\frac{x}{3}-3

A general line can be written as,

y=mx + c

, m= Slope of the line

c=y intercept of the line

Y intercept is basically the point where the line intersects,  the y axis or the line x=0.

Therefore, from the above data m=\frac{1}{3}

and Y intercept= -3.

Which of the following is the balance for a single $2700 deposit in an account with an APR of 4.5% that compounds interest month
Zanzabum

The future amount is $3697.52, if a a single $2700 deposit in an account with an APR of 4.5% that compounds interest monthly and is invested for 7 years.

Step-by-step explanation:

The given is,

                     A single deposit amount - $ 2700

                                                       APR - 4.5%

                                            ( Compounded monthly )

                                                    Period - 7 years

Step:1

                 Formula to find future amount with an APR compounded monthly,

                                                          A = P(1+\frac{r}{n})^{nt}.......................(1)

                Where, A - Future amount

                             P - Initial deposit

                              r - Interest rate

                             n - Number of compounding in a year

                             t - No.of years

                From given,

                         P = $ 2700

                          r = 4.5%

                          n = 12                   (∵ For monthly n becomes 12 )

                           t = 7 years

                   Equation (1) becomes,

                                                           = 2700(1+\frac{0.045}{12})^{(12)(7)}

                                                           = 2700(1+0.00375)^{84}

                                                           = 2700(1.36945)

                                                           = 3697.52

                                                       A = $3697.52

Result:

              The future amount is $3697.52, if a a single $2700 deposit in an account with an APR of 4.5% that compounds interest monthly and is invested for 7 years.

What interest is needed to earn $137.50 on a deposit of $500 for five years if it earns simple interest?
sineoko [7]

Answer:

5.5%

Step-by-step explanation:

Given data

Simple interest =  $137.50

Principal= $500

time = 5 years

We want to find the rate  R

Simple interest= PRT/100

137.50 = 500*R*5/100

137.50=2500R/100

cross multiply

137.5*100= 2500R

13750= 2500R

divide both sides by 2500

R= 13750/2500

R=5.5%

Hence the rate is 5.5%
