b) Regina gets a $50 gift card for the music site. She tries to estimate how
many songs she can buy with the gift card.
Choose which estimate is the most reasonable? Explain (show work).
1.between 30 and 50 2. Around 70 but less then 70 3. Around 70 but more then 70 4. At least 90
The estimation of the songs depends upon the cost of each song
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
Given that Regina gets a $50 gift card for the music site.
She tries to estimate how many songs she can buy with the gift card.
we need to find the best estimate which is the most reasonable.
As the cost of each song is not given its difficult to estimate.
If each song cost 1 then can buy 50 songs
If each song cost 0.5 then can buy 100 songs
Each song cost 0.75 then can buy 66 songs
Hence, the estimation of the songs depends upon the cost of each song

Isolate the variable by dividing each side by factors that don't contain the variable. This will give you the answer below:
X = 2 = Answer D
Answer:
D. 2
Step-by-step explanation:
One way by solving the equality:
[tex]////// 9x - 10 = 3x + 2////// 9x - 10 + 10 = 3x +2 + 10////// 9x - 3x = 3x + 12 - 3x////// 6x = 12///// 6x/6 = 12/6x = 2[/tex]
I can't put each on a line (the site isn't allowing it), so the //// means it goes to another line.
Another way is by replacing x by each of the possible solutions and see which makes the equality true.

Answer:
-0.01x² + 4x + 200
Step-by-step explanation:
To find the difference in profit between the two companies we need to subtract the polynomials.
So,
________________
-0.03x² + 25x - 1500
MINUS
-0.02x² + 21x - 1700
________________
(-0.03x² - (-0.02x²)) = -0.01x²
(25x - 21x) = 4x
(-1500 - (-1700)) = 200
Thus, the difference is
-0.01x² + 4x + 200

3) Anna is selling tickets to the school's gymnastics competition. On the first day, she sells 5 adult tickets and 6 child tickets for a total of $58.00. On the second day, she sells 8 adult tickets and 11 child tickets for a total of $97.00. Which system of linear equations can be used to determine the cost of each adult ticket (x) and each child ticket (y)?
A) 5x + 6y = 58 8x + 11y = 97
B) x + y = 155 x + y = 30
C) 5x − 6y = 58 8x − 11y = 97
D) x + y = 58 8x + 11y = 97
Answer:
I believe it's A) 5x + 6y = 58 8x + 11y = 97
Step-by-step explanation:
Reason is, adult tickets and child tickets are two different things, so they require two different variables, and two different equations because they have two different sums. (This was probably already obvious to you though).

A radio station runs a promotion at an auto show with a money box with 15 $100 tickets, 13 $50 tickets, and 12 $25 tickets. The box contains an additional 20 "dummy”tickets with no value. Three tickets are randomly drawn. Find the probability that all three tickets have no value.
Using the hypergeometric distribution, it is found that there is a 0.0333 = 3.33% probability that all three tickets have no value.
The tickets are drawn without replacement, hence, the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. N is the size of the population. n is the size of the sample. k is the total number of desired outcomes.In this problem:
There is a total of 15 + 13 + 12 + 20 = 60 tickets, hence [tex]N = 60[/tex].Of those, 20 are "dummy" tickets, hence [tex]k = 20[/tex].Three tickets are randomly drawn, hence [tex]n = 3[/tex].The probability that all three tickets have no value is P(X = 0), hence:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,60,3,20) = \frac{C_{20,3}C_{40,0}}{C_{60,3}} = 0.0333[/tex]
0.0333 = 3.33% probability that all three tickets have no value.

Answer:
15cm
Step-by-step explanation:
As we know that in two similar triangles the corresponding sides are proportional . So that ,
=> 4/10 = 6/AB
=> AB = 6 * 10/4
=> AB = 6 * 5/2
=> AB = 15 cm
Answer:
Ans: C) 15cm
Step-by-step explanation:
first you need to find its corresponding sides,
so, 10÷4=2.5
therefore, 6×2.5=15cm (multiple if we are find the big shape)
So, Ans: is 15cm
