Short Answer: n = 5
The chords bear the relationship  of (in this case)

18*(n + 1) = 9 * (n +7)         Remove the brackets 
18n + 18 = 9n + 63              Subtract 9n from both sides.
18n - 9n + 18 = 63
9n + 18 = 63                        Subtract 18 from both sides.
9n = 63 - 18
9n = 45                                Divide by 9
n = 45/9
n = 5   <<<<<<<< Answer

3. A jet took one hour longer flying to Lincoln from Adams at 800 km/h than to return at
Citrus2011 [14]

Answer:

2400 km

Step-by-step explanation:

distance=rate*time

d=rt

d=(800)(t+1)

d=(1200)(t)

the right sides are both equal to d so set them equal to each other

800(t+1)=1200(t)

800t+800=1200t

800=1200t-800t

800=400t

t=800/400

t=2 hours

d=1200*2

d=2400 km

QUESTION 1
RoseWind [281]

Answer:

1) (D)

2) (B)

3) (C)

Step-by-step explanation:

1) Amount borrowed = $1380 (P)

APR =13% or 0.13 (R)

Time = 15 months (T) = 15/12

Interest amount = \frac{P*R*T}{100}

                           =  \frac{1380*13*15}{1200}

                          = $224.25

Total amount  = 1380+224.25

                        = $1604.25

Monthly payment = 1604.25/15 = $106.95 (D)

2) Amount borrowed = $2240

APR = 15% or 0.15

Time = 18 months

Interest = \frac{P*R*T}{100}

           = \frac{2240*15*18}{1200}

          = $504 (B)

3) Amount borrowed = $5500

APR = 11.5% or 0.115

Time = 5 years

n= 12 (compounded monthly)

M = \frac{P}{\frac{1-(1+r/n)^{-nt}}{r/n} }

   = \frac{5500}{\frac{1-(1+\frac{0.115}{12} )^{-60}}{\frac{0.115}{12}} }

  = $120.95 (C)
