Given
Cp of 1 glass tumbler=80.1000
=Rs 80000
Number of broken glass tumbler=50
Number of remaining glass tumbler=1000-50
=950
Sp of one glass tumbler=96
Sp of 950 glass tumbler=96.950
=91200
Now
Sp > Cp so it is profit
Profit%=sp-cp/cp.100
=91200-80000/80000.100
=11200/80000.100
=14%
Answer:
14%profit
Step-by-step explanation:
Cost of 1000 tumblers=1000×80=80,000
50 of them were broken: 1000-50=950
: He sells 950 tumblers of rs.96 each= ( 950×96)
S.P=91200
We can clearly see he gains for rs.11200.
P%=gain/C.P×100
11200×80000×100
=14%

Hope this helps!
pls help G, H, I, J pls explain
Part G
The two angles ABD and DBC form a straight line, so the angles add to 180 degrees.
Let's solve for x.
angle ABD + angle DBC = 180
(0.5x+20) + (2x-10) = 180
2.5x+10 = 180
2.5x = 180-10
2.5x = 170
x = 170/2.5
x = 68
Then we'll use this to find angle ABD
angle ABD = 0.5*x + 20
angle ABD = 0.5*68 + 20
angle ABD = 34 + 20
angle ABD = 54
Answer: 54 degrees============================================================
Part H
Use the value of x we found back in part G to find the measure of angle DBC
angle DBC = 2x - 10
angle DBC = 2(68) - 10
angle DBC = 136 - 10
angle DBC = 126
An alternative is to subtract the measure of angle ABD from 180
angle ABD + angle DBC = 180
angle DBC = 180 - (angle ABD)
angle DBC = 180 - 54
angle DBC = 126
Answer: 126 degrees============================================================
Part I
This time, the two angles add to 90 degrees as shown by the square corner marker.
(angle XYW) + (angle WYZ) = 90
(1.25x - 10) + (0.75x + 20) = 90
2x + 10 = 90
2x = 90-10
2x = 80
x = 80/2
x = 40
which then leads to,
angle XYW = 1.25*x - 10
angle XYW = 1.25*40 - 10
angle XYW = 50 - 10
angle XYW = 40
Answer: 40 degrees============================================================
Part J
We can subtract the result of part I from 90 degrees to get the answer
angle WYZ = 90 - (angle XYW)
angle WYZ = 90 - 40
angle WYZ = 50
Or we could plug the x value x = 40 into the expression for angle WYZ
angle WYZ = 0.75*x + 20
angle WYZ = 0.75*40 + 20
angle WYZ = 30 + 20
angle WYZ = 50
Answer: 50 degrees============================================================
Summary:
The answers we found were
G. 54 degreesH. 126 degreesI. 40 degreesJ. 50 degreesAnswer:
G. m∠ABD = 54°
H. m∠DBC = 126°
I. m∠XYW = 40°
J. m∠WYZ = 50°
Step-by-step explanation:
∠ABD and ∠DBC are supplementary angles. This means their angles have a sum of 180°.
[tex]\frac{1}{2}x+20+2x-10=180\\\frac{5}{2}x+10=180\\\frac{5}{2}x=170\\x=68[/tex]
m∠ABD = 1/2(68) + 20 = 34 + 20 = 54
m∠DBC = 2(68) - 10 = 136 - 10 = 126
Same concept for ∠XYW and ∠WYZ only this time they are complementary angles. This means their angles have a sum of 90°.
[tex]1\frac{1}{4}x-10+\frac{3}{4}x+20=90\\2x+10=90\\2x=80\\x=40[/tex]
m∠XYW = 1 1/4(40) - 10 = 50 - 10 = 40
m∠WYZ = 3/4(40) + 20 = 30 + 20 = 50
Find the HCF of: 5a²b² and 9x³y³
Answer:
1
Step-by-step explanation:
To do this, we can first look at each factor of each number.
For 5a²b², we can split this up into three parts: 5, a², and b². The factors of 5 are 1 and 5, the factors of a² are 1, a, and a² (because a*a = a² and a²*1 = a²), and the factors of b² are 1, b, and b²
For 9x³y³, the factors for 9 are 1, 3, and 9, the factors of x³ are 1, x, x², and x³ (because x * x² = x³ and x³ * 1 = x³), and the factors of y³ are 1, y, y², and y³.
The only number that is a factor of at least 1 item in each number is 1. Therefore, 1 is the HCF
Another way of looking at this is seeing that a, b, x, and y are all different variables with nothing to connect them, so as a result, they will have no common factors except for 1
The sum of a rational number and an irrational number is irrational.
Always true,sometimes true, never true
=========================================================
Explanation:
We can prove this by contradiction.
Let's say
A = some rational numberB = some irrational numberC = some other rational numberand
A+B = C
We'll show that a contradiction happens based on this.
If A is rational, then A = p/q where p,q are two integers. The q cannot be zero.
If C is rational, then C = r/s for some other integers. We can't have s be zero.
Note the following
A+B = C
B = C - A
B = r/s - p/q
B = qr/qs - ps/qs
B = (qr - ps)/qs
B = (some integer)/(some other integer)
This shows B is rational. But this is where the contradiction happens: We stated earlier that B was irrational. A number cannot be both rational and irrational at the same time. The very definition "irrational" literally means "not rational".
In short, I've shown that if A+B = C such that A,C are rational, then B must be rational as well.
The template is
rational + rational = rational
Therefore, we've shown that if A is rational and B is irrational, then C cannot possibly be rational. C is irrational.
Another template is
rational + irrational = irrational

l= 6 ft, w = 2 ft, h= 5 ft what is the surface area of the rectangular prism
104 ft^2
Explanation:
The surface areaa of a rectangular prism is given by the formula:
2 (lw + hl + hw)
l = length
w = width
h = height
Substitute the formula with the givsn dimensions:
2 ([6 x 2] + [5 x 6] + [5 x 2])
= 2 (12 + 30 + 10)
2 (52)
= 104
So the SA is 104 square feet or ft^2

Are the lines 3x+4y=-12 and 6x+2y=6 parallel?
Hi
two lines are parallel only if they have the same slope.
So : 3x+4y = 12
4y = 12 -3x
y = 12/4 - 3x/4
y = 3 - 3/4 X
y = -3/4 X +3
Slope is -3/4
and 6x+2y = 6
2y = 6 -6x
y = 6/2 - 6x/2
y = 3 - 3X
y = -3X +3
Slope is = -3
As -3/4 ≠ -3 then the two lines are not parallel.
A certain box has a width that is 2 inches more than its length and a height that is 5 inches less than its length. If each of the two smallest faces of the box has an area of 36 square inches, what is the volume if the box?
Answer:
V = 396 cubic inches
Step-by-step explanation:
width = w; length = l; height = h; volume = V; area of smallest face = a
base units are inches
w = 2 + l
h = l - 5
Height is smallest and length is second smallest (h = l -, l = l, w = l +), so a is for h and l.
a = h × l = (l - 5) × l
36 = l^2 - 5l ==> l^2 - 5l - 36 = 0
Factor ==> (l - 9) × (l + 4) = 0
l = 9 and l = -4
Since length cannot be negative, 9 is the only Real answer.
l = 9
h = l - 5 = 9 - 5 = 4
w = 2 + l = 2 + 9 = 11
Volume of rectangular prism/box is length times width times height.
V = l × w × h = 9 × 11 × 4 = 396
The volume of the box with the given dimensions is;
Volume = 396 in³
Let us denote the properties of the box as follows;
Length of box = l
Width of box = w
Height of box = h
Area of the smallest face of box = a
We are told that the width is 2 inches more than the length. Thus;
w = 2 + l
We are told that the height is 5 inches less than its length. Thus;
h = l - 5
Since length is smaller than width but bigger than height, the height and length are the 2 smallest faces
Thus,
a = h × l
plugging in the relevant values gives;
a = (l - 5) × l
a = l² - 5l
We are told that the area of the two smallest faces is 36 in². Thus;
l² - 5l = 36
l² - 5l - 36 = 0
Using online quadratic equation solver, we have; l = 9 inches
Plugging in 9 for h in; h = l - 5
h = 9 - 5
h = 4
Also, plugging in 9 for l into; w = 2 + l, we have;
w = 2 + 9
w = 11
Volume of box is given by;
Volume = length × width × height
Volume = 9 × 11 × 4
Volume = 396 in³

In the diagram, △ABC∼△PQR, mAB¯¯¯¯¯¯¯¯=2, and mPQ¯¯¯¯¯¯¯¯=5.
If the perimeter of ΔABC is 3x, what is the perimeter of △PQR?
A. 3/2x
B. 7.5/5x
C. 6x
D. 15/2x
The perimeter of △PQR is, 7.5/5x.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, Based on the given information, since △ABC∼△PQR,
we know that the corresponding sides are proportional.
Therefore, we can set up a proportion:
AB/PQ = BC/QR = AC/PR
Substituting the given values, we get:
2/5 = BC/QR = AC/PR
Since we know the perimeter of ΔABC is 3x, we can express its sides as:
AB + BC + AC = 3x
Substituting AB = 2, we get:
2 + BC + AC = 3x
Dividing both sides by 2, we get:
BC/2 + AC/2 = (3/2)x - 1
Substituting BC/QR = AC/PR = 2/5, we get:
(2/5)QR/2 + (2/5)PR/2 = (3/2)x - 1
Simplifying, we get:
QR + PR = (15/10)x - 2
Since the perimeter of ΔPQR is PQ + QR + PR, we can substitute PQ = 5, and get:
Perimeter of △PQR = 5 + QR + PR
Substituting QR + PR = (15/10)x - 2, we get:
Perimeter of △PQR = 5 + (15/10)x - 2
Simplifying, we get:
Perimeter of △PQR = (7.5/5)x - 2
Therefore, the answer is option B, 7.5/5x.
