Answer:
2% profit
Step-by-step explanation:
x = price
50kg = 50x
30kg => 35x
20kg => 16x
35x + 16x = 51x
51x - 50x = x
50x .............. 100%
x ...................... p%
p = 1×100/50 = 100/50 = 2%
let the CP of per kg fruits be x
subsequently it became,
profit=SP-CP
=51x-50x
=x
Profit%=P/CP*100%
=x/50x*100%
=2%
So, the profit% is 2%
solved

5y^2 - 2 = 3y
Answer:
y= -2/5 and y=1
Step-by-step explanation:
Start by transforming the equation to your liking:
[tex]5y^2-2=3y\\5y^2-3y-2=0\\[/tex]
Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.
Now substitute those two number in place of the middle term, which is -3y like so:
[tex]5y^2-5y+2y-2 =0[/tex]
Now solve the equation in pieces... find the greatest common factor from [tex](5y^2-5y)[/tex] and the greatest common factor from [tex](2y-2)[/tex] . The two common factors for both of those are 5y and 2. Your equation should now look like this:
[tex]5y(y-1)[/tex] + [tex]2(y-1)[/tex]
The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:
[tex](5y+2)(y-1)=0[/tex]
Now equal both of the equations to 0 and solve for y to get both of the values of y.
Pls help me with this geometry question
Answer:
m<1=104°
m<2=38°
m<3=104°
m<4=38°
Solution,
<2=38( diagonal of rhombus divide the angle into two
equal parts)
<4=38°( opposite angles are equal)
Now,
from angle sum property,
38+38+<3=180°
76+<3=180°
<3=180-76
<3=104°
< 3=<1=104
So,
m<1=104°
m<2=38°
m<3=104°
m<4=38°

Step-by-step explanation:
Euclidean geometry is the mathematical technique that are discovered by the Greek mathematician Euclid of the Alexandria .In the In the 19th century fifth postulate of the euclidean geometry are created.
The Euclid approach is to presume the limited number of the influential theoretical axioms as well as to conclude several other proposals.The main objective of fifth postulate of euclidean geometry is to implement the properties of geometry like points ,etc without the use of coordinate geometry .You build a fence around garden that measures 10 x 15 feet; how many feet of chain link fence will you need?
Answer:
50 feet
Step-by-step explanation:
We have to find the perimeter of the fence surrounding the garden.
2l+2w
2(15) + 2(10)
30 + 20
= 50
50 feet will be needed.
Length = 10 feet
Breadth = 15 feet
Perimeter = 2(length + breadth)
= 2(10+15)
= 2 x 25
= 50 feet
Therefore, you will need 50 feet of chain link fence.

ABCD is a rhombus, where m∠AED = 5x – 10. Use the properties of a rhombus to determine the value of x. ANSWERS: A) x = 20 B) x = 5 C) x = 16 D) x = –2
Answer:
A) x = 20
Step-by-step explanation:
ABCD is a rhombus, AC and BD are diagonals which intersect each other at point E.
Since, diagonals of a rhombus are perpendicular bisector.
[tex] \therefore \: m \angle AED = 90 \degree \\ \therefore \: (5x - 10) \degree = 90 \degree \\ \therefore \: 5x - 10 = 90 \\ \therefore \: 5x = 90 + 10 \\ \therefore \: 5x = 100 \\ \\ \therefore \: x = \frac{100}{5} \\ \\ \huge \red{ \boxed{ \therefore \: x =20}}[/tex]

WILL REWARD BRAINIEST!!
Answer:
See below.
Step-by-step explanation:
Recall that the biggest angle will always be opposite from the biggest side.
IT is opposite from Angle S, which we can figure out to be 180-108-25=47.
SI is opposite from Angle T, which is 41.
ST is opposite from Angle I (the whole thing). Just from looking at it, we know that it is the biggest angle. If we want to figure it out, Angle I is 180-41-72+25=92.
The smallest side is SI, then IT, then ST.
The correct order is: SI, IT, and ST.

HELP PLEASE!! Why isn't x+x=x(x) equivalent?
Answer:
The expressions are not equivalent due to the fact that if you were to substitute real numbers you would not get equivalent answers.
Step-by-step explanation:
If you substitute with real numbers, it helps you to get a better view of the equation.
Say you plug in x=5.
5+5 = 5(5)
10=25
The answers are not equivalent.

The truth table represents statements p, q, and r.
If p is false, which row represents when pv(q^r)
HURRYYY PLEASE
Answer:
E
Step-by-step explanation:
In the picture attached, the Truth Table for the operator “OR” is shown. With it we can compute the next table:
p q ∧ r p ∨ (q ∧ r)
T T T
T F T
F T T
F F F
We want that p would be false and p ∨ (q ∧ r) would be true, which corresponds to the third row of the previous table.
The only row from the table of the question that satisfies this criterion is row E.
the object on the right is made from a square-based pyramid joined to a cuboid.
the base of the cuboid and the base of the pyramid are both squares of side 6cm.
the bright of the cuboid is 9cm and the total height of the object is 17cm.
the total mass of the object is 970g.
the cuboid is made from wood with density 0.68g/cm^3
the pyramid is made from steel.
calculate the density of the steel in g/cm^3.
you must show your working.
Answer:
Density of steel = 80.73 gm/[tex]cm^3[/tex]
Step-by-step explanation:
The figure is made up of cuboid and square pyramid.
Height of cuboid, h = 9 cm
Length of cuboid, l = 6 cm
Width of cuboid, w = 6 cm
Volume of cuboid is given by the formula:
[tex]V_{Cuboid} = l \times w \times h[/tex]
[tex]V_{Cuboid} = 6 \times 6 \times 9\\\Rightarrow V_{Cuboid} = 324\ cm^3[/tex]
Density of Wood , [tex]D_{Cuboid}[/tex]= 0.68g/[tex]cm^3[/tex]
We know that formula of Density is:
[tex]Density = \dfrac{Weight}{Volume}[/tex]
[tex]D_{Cuboid} = \dfrac{W_{Cuboid}}{V_{Cuboid}}\\\Rightarrow W_{Cuboid} = V_{Cuboid} \times D_{Cuboid}[/tex]
Putting the values:
[tex]W_{Cuboid} = 324 \times 0.68 = 220.32\ gm[/tex]
Total weight = [tex]W_{Cuboid} + W_{Pyramid}[/tex]
970 = 220.32 [tex]+ W_{Pyramid}[/tex]
[tex]W_{Pyramid}[/tex] = 749.68 gm
Volume of pyramid is given as:
[tex]V_{Pyramid}= \dfrac{1}{3} \times \text{Area of Base} \times \text{Vertical Height}[/tex]
Base is a square with side 6 cm
[tex]V_{Pyramid}= \dfrac{1}{3} \times 6 \times 6 \times (17 -9)\\V_{Pyramid}= 96\ cm^3[/tex]
Density of Steel/Pyramid:
[tex]D_{Pyramid} = \dfrac{W_{Pyramid}}{V_{Pyramid}}\\\Rightarrow D_{Pyramid} = \dfrac{749.68}{96}\\\Rightarrow D_{Pyramid} = 80.73\ gm/cm^3[/tex]
If ABCD is a rectangle, and ABD=55, what is the value of X?
Answer:
x= 70
Step-by-step explanation:
This question needs an attachment; see attached
Given
ABD = 55
Required
Find x?
In the figure shown in the attachment, angle b and ABD are alternate interior angles;
From parallel and perpendicular line theorems; alternate interior angles are equal.
This implies that <b = 55
Also; when a rectangle is divided by two diagonals, the resulting triangles are isosceles triangles;
where 2 sides and 2 angles are equal;
This implies that <b = <c = 55
Sum of angles in a triangle = 180;
So,
<x + <b + <c = 55
x + 55 + 55 = 180
x + 110 = 180
Subtract 110 from both sides
x + 110 - 110 = 180 - 110
x = 180 - 110
x = 70
