Samantha has 54 beads. Amanda has twice as many beads as Samantha. They are making bracelets it takes 8 beads to make a bracelet
wlad13 [49]

Answer:

On combining the beads they can make 20 bracelets.

Step-by-step explanation:

The number of beads Samantha has  =  54 beads

Number of beads Amanda has = 2 x( Number of beads Samantha has)

=  2  x 54  =  108 beads

The total number of beads Amanda and Samantha has  

=   54 beads + 108 beads

= 162 beads

Number of beads required to make 1 bracelet  =  8 beads

Now, \textrm{The number of bracelets made}  = \frac{\textrm{Total number of beads they both have}}{\textrm{Beads required to make 1 bracelet}}

=\frac{162}{8}  = 20.25≈  20

or, the total number of bracelets they can make is 20.

Hence, on combining the beads they can make 20 bracelets .

Determine the time necessary for P dollars to double when it is invested at interest rate r compounded annually, monthly, daily,
kipiarov [429]

9514 1404 393

Answer:

  • annually: 9.01 years
  • monthly: 8.69 years
  • daily: 8.67 years
  • continuously: 8.66 years

Step-by-step explanation:

For interest compounded in discrete intervals, the formula is ...

  A = P(1 +r/n)^(nt)

We want to find t for P=1 and A=2, so we have ...

  2 = (1 +r/n)^(nt)

  ln(2) = nt·ln(1+r/n)

  t = ln(2)/(n·ln(1+r/n))

A table of values for r=0.08 is attached.

__

For continuous compounding, the formula is ...

  A = Pe^(rt)

  t = ln(A/P)/r = ln(2)/0.08 ≈ 8.66434 . . . . years

__

  • annually: 9.01 years
  • monthly: 8.69 years
  • daily: 8.67 years
  • continuously: 8.66 years
