Answer:

17 links

Step-by-step explanation:

<em>1. </em>13 Links and 17 links are rusted. Since we need to find out the number of links that are not rusted, we need to add 13+17.

<em>a.</em><em>  13  + 17 = 30</em>

2. Now since we added the number of lines rusted, we now should subtract the ones rusted and the one not rusted to get the answer.

a. 47-30 = 17

FINAL ANSWER: 17

Mars2501 [29]

Answer:

  The horse-drawn carriage tour company can expect to take in $6960 when the charge per customer is $60.

Step-by-step explanation:

p(2) = 120 -2·2 = 116 . . . . . expected number of customers per day

c(2) = 50 +5·2 = 60 . . . . . . charge per customer

Then ...

  (p·c)(2) = p(2)·c(2) = 116·60 = 6960 . . . . revenue for the day

Please help meeeee. I literally learned this last year but my dum mb self forgot hot to do it
Aleks [24]

It would be 30 because 10^4 is 10000 and 10000 times 12 is 120000 and 10^3 is 1000 and 1000 times 4 is 4000 so 120000 divided by 4000 is 30

An envelope contains $1.20 in dimes and nickels. if the dimes were quarters and the nickels were dimes, there would be $1.35 mor
balu736 [363]

The nickels in the envelope is $0. 12

<h3>How to determine the number</h3>

From the information given, we have that;

Dimes + nickels = $1. 20

1/4 dimes + dimes = $ 1. 35

Let dimes = d

Nickels = n

d + n = 1. 20    equation a

d/4 + d = 1. 35   equation b

Make 'd' subject from equation a

d = 1. 20 - n

Substitute into equation b

1. 20 - n/ 4 + 1. 20 - n = 1. 35

0. 3 - 0. 25n + 1. 20 - n = 1. 35

collect like terms

- 1. 25n = 1. 35 - 1. 5

- 1. 25 = - 0. 15

n = -0. 15/ -1. 25

n = 0. 12

Thus, the number of nickels in the envelope is $0. 12

BabaBlast [244]

The number of ways in which you can win first prize and your mom went the second prize will be 8. Then the correct option is D.

<h3>What are permutation and combination?</h3>

A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.

You and your mom enter the drawing with three different prices the prizes are awarded at random is a total of 8 people entered the drawing.

Then the number of the ways in which you can win first prize and your mom went the second prize will be

Let x be the number of different ways.

Then we have

\rm x = \ ^8C_1\\\\x = 8

Thus, the number of ways in which you can win first prize and your mom went the second prize will be 8.

More about the permutation and the combination link is given below.

Part 1:

Given that a<span> store had 235 MP3 players in the month of January and that every month, 30% of the MP3 players were sold and 50 new MP3 players were stocked in the store.

</span>The number of MP3 players in the store after the previous months sale is given by 0.7f(n - 1) and <span>the number of MP3 players in the store after new MP3 were added is 0.7f(n - 1) + 50.

Therefore, the </span><span>recursive function that best represents the number of MP3 players in the store f(n) after n months is given by </span><span>f(n) = 0.7 x f(n − 1) + 50, f(0) = 235, n > 0



Part 2:

The average rate of change of a function from a to b is given by

average \ rate \ of \ change= \frac{f(b)-f(a)}{b-a}

Given that the </span><span>equation showing the value of her investment after x years is given by

f(x)=500(1.05)^x

Thus, </span><span>the average rate of change of the value of Sophia's investment from the second year to the fourth year is given by

Average \ rate \ of \ change= \frac{f(4)-f(2)}{4-2}  \\  \\ = \frac{500(1.05)^4-500(1.05)^2}{2} = \frac{607.75-551.25}{2}  \\  \\ = \frac{56.5}{2} =28.25

Therefore, the </span><span>average rate of change of the value of Sophia's investment from the second year to the fourth year is 28.25 dollars per year.</span>
