Mr. Jones sold two pipes at $1.20 each. Based on the cost, his profit was 20% and his loss on the other was 20%. On the sale of the pipes, he:
(a) broke even, (b) lost 4 cents, (c) gained 4 cents, (d) lost 10 cents, (e) gained 10 cents
Answer:
Selling price of the first pipe = $1.20
Profit = 20%
Let’s try to find the cost price of the first pipe
CP = Selling price - Profit
CP = 1.20 - 20% of CP
CP = 1.20 - 0.20CP
CP + 0.20CP = 1.20
1.20CP = 1.20
CP = 1.201.20
CP = $ 1
Selling price of the Second pipe = $1.20
Loss = 20%
Let’s try to find the cost price of the second pipe
CP = Selling price + Loss
CP = 1.20 + 20% of CP
CP = 1.20 + 0.20CP
CP - 0.20CP = 1.20
0.80CP = 1.20
CP = 1.200.80
CP = $1.50
Therefore, total cost price of the two pipes = $1.00 + $1.50 = $2.50
And total selling price of the two pipes = $1.20 + $1.20 = $2.40
Loss = $2.50 – $2.40 = $0.10
Therefore, Mr. Jones loss 10 cents.
i know that this is hard to understand so tell me if you need help

help pleaseeeeee thank youuu
$500
Step-by-step explanation:
200 is 40%
I doubled it to get 400$ for 80%,
then I divided 200$ by 2 to get 100, same with the percent. in total, 500$=100%

27 Cm² (C)
...............
==========================================================
Explanation:
It's not directly stated, but I'm assuming that there's symmetry going on in terms of the triangle on the left being a mirror copy of the triangle on the right. If that assumption is true, then we have another "3 cm" along the bottom edge. In total, the bottom edge is 3+6+3 = 12 cm long.
The top edge, parallel to the bottom one, is 6 cm. We'll denote the two parallel sides to be the base lengths and we could write [tex]b_1 = 6 \text{ and } b_2 = 12[/tex]. The small subscript just helps us differentiate between the two base lengths.
The height is the vertical dashed line of 3 cm. This means h = 3. The height is always perpendicular to the base.
We'll plug those three variables into the area of a trapezoid formula below
[tex]A = \frac{h*(b_1+b_2)}{2}\\\\A = \frac{3*(6+12)}{2}\\\\A = \frac{3*(18)}{2}\\\\A = \frac{54}{2}\\\\A = 27\\\\[/tex]
The area is 27 square cm
-----------------------------------
Another way to get the answer is to break the trapezoid into three pieces: two triangles and a rectangle in between.
One triangle has an area of base*height/2 = 3*3/2 = 9/2 = 4.5 square cm, which means two triangles combine to an area of 2*4.5 = 9 square cm.
The rectangle has area of length*width = 6*3 = 18 cm^2
The trapezoid's area is the combination of what we found: 9+18 = 27 cm^2

Answer:
A. The constant ratio of y/x is 12/5
Step-by-step explanation:
The ratio of y to x is constant which is 12/5. Hence option A is the correct option.
What is a constant?
The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings: a constant, clearly defined number or another immutable mathematical object.
Given table is
x y
5/6 2
25/6 10
125/6 50
625/6 250
When x = 5/6 and y = 2:
x/y = (5/6)/2 = 5/12
∴y/x = 5/12
When x = 25/6 and y = 10:
x/y = (25/6)/10 = 25/60 = 5/12
∴y/x = 5/12
When x = 125/6 and y = 50:
x/y = (125/6)/50 = 125/300 = 5/12
∴y/x = 5/12
When x = 625/6 and y = 250:
x/y = (625/6)/250 = 625/1800 = 5/12
∴y/x = 5/12

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply. 7 x + 4 and 3 x + 5 + 4 x minus 1 When x = 2, both expressions have a value of 18. The expressions are only equivalent for x = 4 and x = 6. The expressions are only equivalent when evaluated with even values. The expressions have equivalent values for any value of x. The expressions should have been evaluated with one odd value and one even value. When x = 0, the first expression has a value of 4 and the second expression has a value of 5. The expressions have equivalent values if x = 8.

Answer:The mean goes up from approximately 80.4 to 82.
Step-by-step explanation:
Before adding 101°, the mean i2:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57)/12 = 80.4
After adding the value 101°, the mean is:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 101)/13 = 82
The mean goes up from approximately 80.4 to 82.

Two lines meet at a point that is also the vertex of an angle. Set up and solve an appropriate equation for and .
Answer:
Y=74, x=106.
Step-by-step explanation:
First, if you will notice, that 16+Y=90. Why? Because there is a square instead of a semicircle at the angle, which means that 16+Y=90. 90-16=74, so Y is 74. Then, we see that 90 plus an unknown angle equals x. But, using a rule of geometry, we know that the unknown angle is 16. So, x=90+16, and since 90+16 is 106, we get Y=74, X=106.

Step-by-step explanation:
If the mean absolute deviation is close to 0, then what does that mean about the data set
The average difference is very less of all the elements in a data set than the mean of the same data set.
What is the mean absolute deviation?It is defined as the measure to show the variation in data set in other words between the mean and every data value the distance is known as the MAD.
As we know the mean absolute deviation is the average distance between each data point and the mean.
The mean (average) difference between each data value and the data set's mean is known as the mean absolute deviation. It can be used to quantify the data set's dispersion as well as to solve statistical issues in the actual world.
If the mean absolute deviation is close to 0 it means the average difference is very less of all the elements in a data set from the mean of the same data set
Thus, the average difference is very less of all the elements in a data set than the mean of the same data set.
