Makovka662 [10]3 years ago
3 0

Answer:

  • See below

Step-by-step explanation:

  • 1) Total points = 25
  • 2) Points earned = 21
  • 3) Percent score = 84%

<u>Proportion:</u>

  • 21 / 25 = 84% / 100%

Solving the others in the table

<u>21 out of 25 points:</u>

  • 21/25 = x/ 100 ⇒ x = 100*21/25 = 84

<u>15 out of 20 points:</u>

  • 15/20 = x/100 ⇒ x = 100*15/20 = 75

<u>47 out of 50 points:</u>

  • 47/50 = x/100 ⇒ x = 100*47/50 = 94

<u>28 out of 30 points:</u>

  • 20 / 30 = x/100 ⇒ x = 100*20/30 = 66.66

<u>19 out of 45 points:</u>

  • 19/45 = x/100 ⇒ x = 100*19/45 = 42.22

<u>3 out of 4 points:</u>

  • 3/4 = x/100 ⇒ x = 100*3/4 = 75

Suppose James has a credit card with a balance of 4289 . Each month the credit card company charges 5% interest. If James pays o
topjm [15]

Answer:

<h2>4076.56</h2>

Step-by-step explanation:

First we need to calculate the James monthly charges on his balance of 4289.

Using the simple interest formula;

Simple Interest = Principal * Rate * Time/100

Principal = 4289

Rate = 5%

Time = 1 month = 1/12 year

Simple interest = 4289*5*1/12*100

Simple interest = 21,445/1200

Simple interest = 17.87

<u>If monthly charge is 17.87, yearly charge will be 12 * 17.87 = </u><u>214.44</u>

The balance on his credit card one year from now = Principal - Interest

= 4289 - 214.44

= 4076.56

The balance on his credit card one year from now will be 4076.56

A cylinder has a radius of 5x + 4 and a height of 2x + 5. Which polynomial in standard form best describes the total volume of t
Nana76 [90]

Answer:

Step-by-step explanation:

Volume = pi·(r^2)*h

r = radius = (5x+4)

h = height = (2x+5)

 

Volume = pi·(r^2)

Volume = pi·(5x+4)^2*(2x+8)

Volume = pi·(25x^2+40x+16)*(2x+8)

Volume = pi·(50x^2+80x+32+200x^2+32x+128)

Volume = pi·(250x^2+112x+160)

HELP PLEASE IM REALLY STUCK
liberstina [14]
The 15th term will be 71. Why? Well, see below for an explanation!

By subtracting all of these numbers by the term that comes prior to them, we will find that all of them result in 5. Because of this, we know that each time the term increases, 5 is being added to the numbers. Additionally, I noticed that all of the numbers in this arithmetic sequence only end in a 1 or a 6. Because of this, we can apply the same principle when adding 5 each time:

First term: 1
Second term: 6
Third term: 11
Fourth term: 16
Fifth term: 21
Sixth term: 26
Seventh term: 31
Eighth term: 36
Ninth term: 41
Tenth term: 46
Eleventh term: 51
Twelfth term: 56
Thirteenth term: 61
Fourteenth term: 66
Fifteenth term: 71

By adding 5 each time and keeping in mind that the digits all end in only 1 or 6, we will find that the fifteenth term results in 71. Therefore, the 15th term is 71.

Your final answer: The 15th term of this arithmetic sequence comes down to be 71. If you need extra help, let me know and I will gladly assist you.

Which term best describes the definition below?
Amiraneli [1.4K]
When a set of objects are chosen from a larger set in which the order of the object doesn't matter, we call this combination. Otherwise if the order of selection would matter this would be called a permutation.
Probability 
is the likelihood of selecting a particular specified object in from a specified group of objects.
Therefore our answer is B.

Graph the function f(x)=3/2x−4. Use the line tool and select two points to graph.
iris [78.8K]

Answer:

Two points on the graph would be (2,-1) and (4,2).

Step-by-step explanation:

You can choose two random x variables such as how i selected 2 and 4. if you change the variable x to those values you can solve for y or in this case f(x).

EX:

3/2*2-4

6/2-4

3-4

f(x)= -1
