Is this a Percent Increase or Decrease Problem?
Kemyah bought a necklace for $260 that was marked
up by 30%.
Answer:
increase
Step-by-step explanation:
....................
Answer:
Percent Increase
Step-by-step explanation:
Percent Increase because if the necklace was bought for $260, and was marked up by 30%, it means it was originally a lower price, that was multiplied by 130%.
Explanation by algebra:
x + 0.30x = 260
1.3x = 260
x = 260/1.3
x = 200
The necklace was originally $200, and it was marked up by 30$, making it $260.

Click the score on the graph where you think the
balancing point would be for this data.
Answer:
The balancing point is 23
Step-by-step explanation:
Given
The above graph
Required
Determine the balancing point
This simply means that we calculate the mean.
From the above graph, we have:
[tex]\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}[/tex]
So, the mean is:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
[tex]\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}[/tex]
[tex]\bar x = \frac{230}{10}[/tex]
[tex]\bar x = 23[/tex]
Hence, the balancing point is 23

A diamond retailer buys a ring from his supplier

diamond with a 6% sales tax?
Answer:
nerd is 18
Step-by-step explanation:
xsas
Answer: $1,947.75
Step-by-step explanation: First, the mark up is 110% of the total, which is $875. 110% of 875 is $962.50, which you add to the total ($875) since it is mark up. $962.50 + $875 = $1837.50. Finally, 6% of $1837.50 is $110.25 so you add this to your new price ($1837.50) since the 6% is the sales tax. $1837.50 + $110.25 = $1947.75

Determine the amplitude or period as requested . Amplitude of y = - 1/3 * sin x
Answer: amplitude and period are two different things. The amplitude is -1/3, and the period is 360 degrees.
Step-by-step explanation: to find the amplitude, you just look at what number is in front of sin. If there isn't one, an amplitude of 1 is implied (in this case. Keep in mind that different functions have different standards).
To find the period, you take term b (which is what comes after sin). In this case, b is 1 because there's no specific number there. Again, it's implied. Because this is sin and not tan, for example, you take 360/b=period. 360/1=360 degrees.

If $a$, $b$, $c$, and $d$ are replaced by four distinct digits from $1$ to $9$, inclusive, then what's the largest possible value of the difference $a.b - c.d$ ?
Answer:
Correct answer is 18.3Dollar replacement 70Step-by-step explanation:
Correct answer
Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.
This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.
It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the one-digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:
9.7 + 8.6 which results to 18.3
9.6 + 8.7 yields 18.3 as well.
Dollar replacement
For the value of the difference to be largest, the minuend should be maximum(most possibly) and the subtrahend should be minimum
[in A-B=X, A is minuend and B is subtrahend ]
So, $a.b should be the maximum. as there is a condition that 4 digits should be distinct, the product will be maximum if we choose 2 maximum valued numbers from the given numbers. so, one of them should be 9 and the other should be 8.
Therefore, $a.b=9*8=72
As mentioned above, c.d$ should be minimum. this will be possible only when we choose 2 minimum valued numbers from the given numbers. so, one of them should be 1 and the other should be 2.
Therefore, c.d$ = 1*2 = 2
Hence, the difference = 72-2 = 70
Thus, the largest possible value of the difference $a.b - c.d$ = 70
Answer:
8.6
Step-by-step explanation:
The units digits matter most, so we make a as large as possible (a=9) and make c as small as possible (c=1). Then we can use any of the digits from 2 through 8. We still want b as large as possible and d as small as possible so we set b=8 and d=2. This gives a maximum possible difference of 9.8 - 1.2 = 8.6.

What is the equation of the circle, with center (4, 2) and radius 5 units?
Answer:
Step-by-step explanation:
Let us begin by just getting the equation of the circle first.
(x - 4)^2 + ( y - 2)^2 = 5^2
(x - 4)^2 + ( y - 2)^2 = 25
Now I'm going to graph that equation and discuss it here.
I have graphed the second equation above.Notice that the center is at (4,2) just as the question requested.A second point was put at (4,7). That was to show you that the radius is 5 units. You can calculate that it is 5 units by noticing that 7 - 2 = 5 So the distance from the center to (4,7) is 5 units which is the amount of the radius.Notice that the numbers representing the center have been reversed in sign. That is always done for a circle. The center's coordinates are always the negative of the coordinates given. You will be told why later.What is the distance between these two points?
Answer:
Step-by-step explanation:
The two points are (-6,8) and (8,0)
we can find the distance thanks to this formula
√(x1-x2)^2 + (y1-y2)^2 where x and y indicate the coordinates of the two points
√(-6-8)^2 + (8)^2 = √196 + 64 = √260 ≃ 16,12

Answer:
ans is 504m²
Step-by-step explanation:
given = side of square=18m
height of triangle=12m
formula= surface area of square + surface area of 4 triangles
surface area of square = 4 × length
= 4×18
=72m²
surface area of triangle = 1/2×base ×height
= 1/2×18×12 ( the base lies on the side of the squre so the base is also 18m)
= 108m²
therefore, surface area of 4 triangles = 4×108=432m²
therefore the surface area of the given figure= surface area of aquare + surface area of the 4 triangles
surface area of square= 72 +432
=504m²
