Kelsie sold digital cameras on her website. She bought the cameras for $65 each and included a 60% markup to get the selling price. To the nearest dollar, what was the selling price for one camera? Please show work.
Answer:
$104
Step-by-step explanation:
Find 60% of 65 then add it to 65:
0.6 * 65 = 39
Now add it to 65:
39 + 65 = 104
Therefore she's selling cameras for $104 each.

how do you get -11.9 from -6.7+(-5.2)
and explain in words how
If you just type that exact equation into a calculator it gives you the same answer as well
Answer:
You get -11.9 from -6.7+(-5.2) because you are adding 2 negative numbers. Just forget the negative signs are there when your adding negatives. 6.7 + 5.2 = 11.9 and then just add the negative in front and that's how you get your answer -11.9
Hope this helped!

Which equation is equivalent to x + 139 = 537
But where are the equations?
Answer:
You need to give us the answers
Step-by-step explanation:
David buys 2 DVDs and 2 CDs in a shop and in total they cost £18.
Ellie buys 3 DVDs and 2 CDs in the same shop and they cost £22.
Form two equations and solve to find the cost of each DVD and each CD.
Answer: Down below
Step-by-step explanation:
Let x be the cost for the DVD's
Let y be the cost of the CD's
Equations :
2x + 2y = 18 OR y = (18 - 2x)/2
3x + 2y = 22
Substitution :
3x + 2[(18 - 2)/2] = 22
3x + 2(16/2) = 22
3x + 2(8) = 22
3x + 16 = 22
3x = 22 - 16
3x = 6
x = 6/3
x = 2
that's just the cost of the DVD though. now to find the CD's cost
Cost of CD's :
y = (18 - 2x)/2
y = [18 - 2(2)]/2
y = (18 - 4)/2
y = 14/2
y = 7
therefore 1 CD costs 7 pounds and 1 DVD costs 2 pounds

Beatriz takes a simple random sample of 350350350 orders from the more than 500050005000 total orders to her store and finds that 12\, percent of the sampled orders were returned. Assuming that it is really 9\%9%9, percent of all orders to her store which were returned, what is the approximate probability that more than 12\, percent of the sampled orders would have been returned
If Beatriz takes a simple random sample of 350 orders from the more than 5000 total to her store and finds. The probability that more than 12 percent of the sampled orders would have been returned is 0.02.
How to find the probability?Mean = n * p
Mean = 350 * 0.09
Mean= 31.5
Standard deviation = √ p * (1 - p)/n
Standard deviation = √ 0.09 * 0.91/350
Standard deviation = 0.01529
Using the normal distribution table
p>0.12
P(p>0.12) =0.02
Therefore the probability that more than 12 percent of the sampled orders would have been returned is 0.02.

Which expression is equivalent to 1/144
Answer: 1 12/12
Step-by-step explanation:
Answer:
[tex]\displaystyle \frac{12^5}{12^7}[/tex]
Step-by-step explanation:
Equivalent Fractions
We need to recall the following properties of exponentials:
[tex]\displaystyle \frac{x^a}{x^b}=x^{a-b}=\frac{1}{x^{b-a}}[/tex]
Additionally, we have that 144=[tex]12^2[/tex], thus the given expression
[tex]\displaystyle \frac{1}{144}=\frac{1}{12^2}[/tex]
From the options presented, we have to find which one gives 12 squared in the denominator. It's apparent that the first choice:
[tex]\displaystyle \frac{12^5}{12^7}=\frac{1}{12^{7-5}}=\frac{1}{12^2}[/tex]
Is the correct choice.

Given a set of elements corresponding to the domain, we obtain the range by evaluating the function at each value:
22. [tex]f(x) = x^{2}-3[/tex]
[tex]f(-2) = (-2)^{2}-3[/tex]
[tex]f(-2) = 1[/tex]
[tex]f(0) = 0^{2}-3[/tex]
[tex]f(0) = -3[/tex]
[tex]f(2) = 2^{2}-3[/tex]
[tex]f(2) = 1[/tex]
[tex]f(4) = 4^{2}-3[/tex]
[tex]f(4) = 13[/tex]
The set of ordered pairs associated with the given function is:
[tex]S = \{(x,y)|(-2,1), (0,-3), (2,1), (4,13)\}[/tex]
23. [tex]g(x) = -5\cdot x + 2[/tex]
[tex]g(-4) = -5\cdot (-4)+2[/tex]
[tex]g(-4) = 22[/tex]
[tex]g(-1) = -5\cdot (-1) + 2[/tex]
[tex]g(-1) = 7[/tex]
[tex]g(3) = -5\cdot (3) +2[/tex]
[tex]g(3) = -13[/tex]
The set of ordered pairs associated with the given function is:
[tex]S =\{(x,y)|(-4,22),(-1,7),(3,-13)\}[/tex]
There is a six sided polygon in which the first side is a line, the second side is a line segment, the third side is an arrow whose head is in the direction of the point of intersection of second side, the fourth side is a line, the fifth side is a line segment and the last side is an arrow whose head is in the direction of the point of intersection of fifth side. The exterior angle formed by the first and sixth side is labeled as 1, the exterior angle formed by first and second side is labeled as 2, the exterior angle formed by second and third side is labeled as 3, the exterior angle formed by third and fourth side is labeled as 4, the exterior angle formed by the fourth and fifth side is labeled as 5, and the exterior angle formed by the fifth and sixth side is labeled as 6. The interior angle of fifth and sixth side is a right angle.
If ∠1 ≅ ∠2 ≅ ∠3, ∠4 ≅ ∠5, and m∠4 = m∠3 + 10°, What is m∠5?
The interior angle of fifth and sixth side is a right angle is m∠5 =60°.
What is an angle?Two rays that have a common vertex, also known as the angle's sides, are what make up an angle in Euclidean geometry.The plane that contains the rays is where two rays' angles are located. Two planes intersecting at an angle also produces an angle. Dihedral angles are what these are known as. Two rays (half-lines) that share a terminal make up an angle.As we can see, it has a hexagonal shape, and each of its six inner angles has a total measure of 720 degrees.We assume the interior angles of the hexagon are 1', 2', 3', 4', 5' and 6' as the image attached.The hexagon has six pairs of supplementary angles, numbered 1 and 1', 2 and 2', 3 and 3', 4 and 4', 5 and 5', and 6 and 6', all of which are exterior angles.=> m∠1 + m∠1' = m∠2 + m∠2'=m∠3+m∠3' = m∠4 + m∠4' = m∠5 + m∠5' = m∠6 + m∠6' = 180 degree
=> m∠1 + m∠1' + m∠2 + m∠2' + m∠3+m∠3' + m∠4 + m∠4' + m∠5 + m∠5' + m∠6 + m∠6' = 180 × 6 = 1080
=> (m∠1 + m∠2 + m∠3 + m∠4 + m∠5+m∠6) + (m∠1' + m∠2' + m∠3' + m∠4' + m∠5' + m∠6') = 1080
=> (m∠1 + m∠2 + m∠3 + m∠4 + m∠5+m∠6) + 720 = 1080
=> (m∠1 + m∠2 + m∠3 + m∠4 + m∠5+m∠6) = 360 (1)
As given:
+) m∠6 = 90
+) ∠1 ≅ ∠2 ≅ ∠3
+) ∠4 ≅ ∠5
In equation (1), if we substitute 1, 2, and 5 for 3, 4, and 90, respectively, we get
m∠3 + m∠3 + m∠3 + m∠4 + m∠4 + 90 = 360
=> 3m∠3 + 2m∠4 =270 (2)
As given: m∠4 = m∠3 + 10°
Replace in the equation (2), we have:
3m∠3 + 2 × (m∠3 + 10) =270
=> 3m∠3 + 2m∠3 + 20 = 270
=> 5m∠3 = 270 -20 = 250
=> m∠3 = 250/5 = 50°
=> m∠4 = m∠3 + 10° = 50 + 10 = 60°
As ∠4 ≅ ∠5 => m∠5 ≅ m ∠4 =60°
