Answer:
$49.572
Step-by-step explanation:
Given that :
Cost per disc = $18
Number of disc purchased = 3
Discount received = 15%
Sales tax = 8%
Original cost : cost per dic * number purchased
Original cost = $18 * 3 = $54
Discounted price = (100 - 15)% * $54
Discounted price = $45.9
Sales tax :
(100 + 8)% of $45.9
108% * $45.9
= $49.572
Total price = $49.572

Which graph shows a dilation?
The second graph is the only option that has equal increment by a common factor and it is the only graph that shows dilation.
A dilation in graph is also known as transformation.
In the process of transformation or dilation in graph, all distances on the coordinate plane are increased by a common factor. It usually involves multiplying either all x-coordinates or all y-coordinates by a common factor greater than one.The increased x-coordinates is known as horizontal dilation and the increased y-coordinate is known as vertical dilation.
The second graph is the only option that has equal increment by a common factor. Thus, the second graph shows dilation.

A pumpkin is thrown out of a window that is 4 feet high with an upward velocity of 14. When will the pumpkin hit
the ground?
A. 0.4 seconds
OB. 1.1 seconds
O c. 7 seconds
OD. 0.22 seconds
Answer:
Step-by-step explanation:
Given
Height H = 4 feet
Velocity = 14ft/s
Required
Time the pumpkin will hit the ground
Using the equation of mottion
H = ut + 1/2gt²
4 = 14t + 1/2(9.8)t²
4 = 14t + 4.9t²
4.9t²+14t-4 = 0
t = -14±√196+16(4.9)/2(4.9)
t = -14±√196+78.4/2(4.9)
t = -14±16.57/9.8
t = -14+16.57/9.8
t = 2.57/9.8
t = 0.2seconds
Mrs. Hollern works in a jewelry store and
earns an 8.5% commission on every piece of
jewelry she sells. How much commission
would she earn for selling a necklace that
costs $4,600?
Answer:
May 06, 2018 · Real estate agents, car dealers, and pharmaceutical sales representatives earn commissions that are a percentage, or part, of sales. For example, a real estate agent might earn a portion of the selling price of a house that she helps a client purchase or sell. A car salesperson earns a portion of the selling price of an automobile that she sells.
$391 is earned by Mrs. Hollern for selling a necklace that costs $4,600
Since a commission of 8.5%(0.085) is earned for each jewelry sold, hence the total commission (y) for selling x worth of jewelry is:
y = 0.085x
Hence for selling $4600, the commission earned is:
y = 0.085(4600)
y = 391
Hence $391 is earned by Mrs. Hollern for selling a necklace that costs $4,600.

A civics teacher asked her students to indicate whether they believed each of two headlines. One headline was false and the other was true, but the students did not know this. The probability that a student selected at random believed the true headline was 90\%90%90, percent and the probability that the student believed the false headline was 82\%82%82, percent. She found that 75\%75%75, percent of the students believed both headlines.
Answer:
The events are not mutually exclusive.
Step-by-step explanation:
To determine that in the sample, are the events "believed the false headline" and "believed the true headline" mutually exclusive.
For two events, let say E₁ and E₂ are said to be mutually exclusive if they cannot both occur simultaneously. In set-theoretical notation, we can say that the two sets E₁ and E₂ are disjoint. i.e. E₁ ∩ E₂ = ∅ and the probability of them occurring at the same time is zero. i.e. Pr( E₁ ∩ E₂ ) = 0
So, we can say;
Let P(true) = E₁
P(false) = E₂
Thus; statistically:
Pr( E₁ ∩ E₂ ) = Pr(E₁) + Pr(E₂) - P( E₁ ∪ E₂ )
So;
the probability of students that believed the true headline P(E₁) = 0.90
the probability of students that believed the false headline P(E₁) = 0.82
the probability of students that believed both P( E₁ ∪ E₂ ) = 0.75
∴
Pr( E₁ ∩ E₂ ) = 0.90 + 0.82 - 0.75
Pr( E₁ ∩ E₂ ) = 0.97
Thus, the events are not mutually exclusive.

HELP PLEASE!! Multiply.
(2x−7)(x+4)
Enter your answer in the box.
Answer:
2[tex]x^{2}[/tex]+x-28
Step-by-step explanation:
To solve binomial multiplication problems you can use the FOIL method. FOIL means first, outside, inside, last, which tells you what order to multiply the terms.
Multiply the first terms,
(2x-7)(x+4)
2[tex]x^{2}[/tex]
Then the outside terms,
(2x−7)(x+4)
8x
Next the inside terms,
(2x−7)(x+4)
-7x
Finally the last terms,
(2x−7)(x+4)
-28
To find the answer put all of the products together and simplify
2[tex]x^{2}[/tex]+8x-7x-28
2[tex]x^{2}[/tex]+x-28

what is 10 1/3 as an improper fraction
Answer:
31/3
Step-by-step explanation:
Multiply the denominator by the whole number 3×10=30
Then add the numerator 30+1=31
Hope this helps :)
The resulting improper fraction is 31 / 3.
To convert the mixed number 10 1 / 3 to an improper fraction, we first multiply the whole number (10) by the denominator of the fractional part (3), which gives us 30.
Then, we add the numerator of the fractional part (1) to get 31. We write the sum (31) as the numerator and keep the denominator (3) the same.
The resulting improper fraction is 31 / 3.
This means that 10 1/3 is equivalent to 31 / 3. The improper fraction emphasizes the total number of thirds, which is 31, without any whole number component.
