Answer:

$3474.25

Step-by-step explanation:

Use the compound amount formula A = P(1 + r)^t.  Here r is the rate as a decimal fraction and is -0.15.  t represents the number of y ears.  P is the initial value of the car.

Then:  A = ($15,000)(1 - 0.15)^9, or

           A = ($15,000)(0.85)^9  = $3474.25

Joe has fraction 5 over 6 pound of bird seed. He needs fraction 1 over 3 pound to feed the birds daily. Which of the rectangle m
Semenov [28]

Since Joe has 5/6 pounds left and he only needs 1/3 pounds each day to feed the birds, therefore the number of remaining day’s worth of seed is:

days = (5/6) / (1/3) = 2.5

The remaining seed can run up to 2 and half days. This also means that after 2 days, he is remained with ½ of 1/3 pound. ½ of 1/3 pound is equivalent to 1/6 pound. Therefore the correct rectangle model to use is:

<span>Rectangle model divided into 3 equal sections, two sections are labeled one-third and one section is labeled one-sixth, equaling two and one-half days.</span>

The sum of the first k terms in the sequence is 118096, find the value of k. The first term is 78732 the common ratio is 1/3.
FrozenT [24]

Answer:

k = 10

Step-by-step explanation:

The sum of k terms of a geometric sequence with first term a1 and common ratio r is given by ...

... Sk = a1·(1 -r^k)/(1 -r)

For the given numbers, this is ...

... 118096 = 78732·(1 -(1/3)^k)/(1 -1/3)

Manipulating this to get the term containing k, we have

... 1 -(2/3)(118096/78732) = (1/3)^k

... 1/59049 = (1/3)^k

Taking logarithms, we get

... -log(59049) = -k·log(3)

... log(59049)/log(3) = k = 10

Bouncing Baby Company sells their cribs for the following amounts to stores
xz_007 [3.2K]

Answer:

Option C

Step-by-step explanation:

Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,

P ∝ N

P = kN

Here 'k' is the proportionality constant

To get the value of proportionality constant,

Since, value of 10 cribs is $1320

1320 = k(10)

k = 132

Therefore, equation will be

P = 132N

Option A

If number of cribs = 6

P = 132(6) = $792

False.

Option B

For N = 22

P = 132(22) = $2904

False.

Option C

For N = 40

P = 132(40) = $5280

True

Option D

For N = 55

P = 132(55) = $7260

False

Option E

For N = 80

P = 132(80)

  = $10560

False

Option F

For N = 250

P = 132(250)

  = $33000

False

If the given options have been written correctly only one option, Option (C) is correct.
