9.

Calculate the number of sides in a regular polygon if its exterior angle is one sixth of a complete angle

Answer»

GIVEN :

Its exterior ANGEL is one sixth of a complete angle

complete angle is 360 °

Exterior angle = 360 ° / 6

Exterior angle = 60 °

This is a exterior Angle

To FIND the interior angle

Interior angle = 90° - 60°

Interior angle = 30°

To find the number of sides

we know ,The RELATIONSHIP between

Interior angel and number of sides

a × n = 360°

30° × n = 360°

n = 360°/30°

n = 12

Number of sides in the regular polygon is 12

Name of this polygon is dedacogon.

That is shown in above image

12.	How much above the cost price should a dealer mark his goods so that after allowing a discount of 10%on the marked price he gains 8%
Answer» solution:- let the CP be RS. 100 and MP be Rs. x gain % after discount = 12% gain = 12% of 100 = Rs. 12 ⇒ SP of the article = CP + Gain = Rs. (100 + 12) = Rs. 112 Discount % = 20% Discount = 20% of Marked Price = Rs.20/100 * x = Rs. 20x/100 = Rs. x/5 as da question says marked Price - discount = SP => x - x/5 = 112 => (5X - x)/5 = 112 => 4x/5 = 112 => x = 112 * 5/4 = Rs. 140 marked Price = Rs. 140 amount marked above the CP = MP - CP = Rs. (140 - 100) = Rs. 40 ∴ % amount marked above the CP = Amount increased/CP * 100 = 40/100 * 100 = 40% ================================================= pls FOLLOW tannuranna 59 in my following and me ✌️

12.

How much above the cost price should a dealer mark his goods so that after allowing a discount of 10%on the marked price he gains 8%

Answer»

solution:-

let the CP be RS. 100 and MP be Rs. x

gain % after discount = 12%

gain = 12% of 100 = Rs. 12

⇒ SP of the article = CP + Gain

= Rs. (100 + 12) = Rs. 112

Discount % = 20%

Discount = 20% of Marked Price

= Rs.20/100 * x

= Rs. 20x/100

= Rs. x/5

as da question says

marked Price - discount = SP

=> x - x/5 = 112

=> (5X - x)/5 = 112

=> 4x/5 = 112

=> x = 112 * 5/4 = Rs. 140

marked Price = Rs. 140

amount marked above the CP = MP - CP

= Rs. (140 - 100)

= Rs. 40

∴ % amount marked above the CP

= Amount increased/CP * 100

= 40/100 * 100

= 40%

34.

The area of an isosceles triangle is 12 CM square. If one of its equal sides is 5 cm,find its base.

Answer»

Answer:

8 cm or 6 cm could be the bases

Step-by-step explanation:

Let half of the BASE be 'b'

Hypotenuse of the triangle = 5 cm

Base= b Height=h

Area of a triangle= 1/2*b*h

Here, the entire base is 2b

THEREFORE, 1/2*2b*h=12cm^2

b*h=12 cm^2

To proceed further,

Let 'h' be 12/b cm

Pythagoras property

a^2+b^2=c^2

b^2+(12/b)^2= 5^2

b^2+(144/b^2)=25

(b^4+144)/b^2=25

b^4+144=25b^2

b^4-25b^2+144=0

By spiting the middle term,

b^4-9b^2-16b^2+144

b^2(b^2-9)-16(b^2-9)

(b^2-16)(b^2-9)=0

Either,(b^2-16)=0 or (b^2-9)=0

Either b^2=16 or (b^2=9)

Therefore, b can be either 4 or 3

As 2b is the base, it can be either 8 cm or 6 cm

If 8 cm is the base, then 3 cm will the height.

If 6 cm is the base, then 4 cm will be the height.

Hope it helps you!!!

The sum of two numbers is 32 and the product of half the larger and the smaller is 96. What are numbers?

Answer»

Answer:

given x+y=32.....1ST equation and

xy/2=96.....2nd equation and xy=192 and

y=192/x......3rdeq

Step-by-step EXPLANATION:

do sobs(SQUARING on both sides) of eq 1 then we get x^2+y^2=640........4TH eq then subtract 1st eq from 4th eq we get x+y=32 then substitute eq 3 in it then we will get a quadratic equation then LIKE x^2-33x+192=0 then solve this qe using formula method the answer is 24,8

38.	If x+1/x=4,find the value of x3+1/x3 its urgent
Answer» Answer: Answer: X+1/ x = 4 x+1 = 4x 1 = 3x x = 1/3 so x^3 + 1/x^3 = (1/3)^3 + 1/(1/3)^3 is 8

38.

If x+1/x=4,find the value of x3+1/x3 its urgent

Answer»

Answer:

Answer:

X+1/ x = 4

x+1 = 4x

1 = 3x

x = 1/3

so x^3 + 1/x^3 = (1/3)^3 + 1/(1/3)^3

44.

Find the centre of the circle, if the end points of the diameter are (3, - 10), (2,-3) and (1, 4)

Answer»

Answer:

EQUATION OF CIRCLE IN DIAMETRIC FORM IS

(x–x1)(x–x2) + (y–y1)(y–y2) = 0

take any two set of COORDINATES and solve

you will get an equation of the form

x²+y²+2gx+2fy+c=0

and CENTRE would be (–2g/2 , –2f/2)

i.e.( –g , –f)

THE ANSWER YOU WOULD GET WOULD BE CENTRE = (5/2 , –13/2)
