Answer:
33.33%
Step-by-step explanation:
Given that CP for 20dozen = 20×90
= 1800
SP = 20×120
= 2400
Gain % = (Gain / CP) ×100
Gain = SP-CP
So is the selling price
Cp is the cost price
Hence Gain = 2400-1800
Gain = 600
Gain% = 600/1800 ×100/1
= 0.333×100/1
= 33.33%
Hence his percentage gain will be 33.33%
Since the question stated that percentage gain is to be calculated, I believe the sell price should be higher than the cost price. Hence 1.20 Cedis would not work so I used 120 Cedis instead. Thanks
If this is what u are asking for 240 is what i got for the answer
Let
x--------> the side length of the cube
we know that
[volume of a cube]=x³
[volume of a pyramid]=[area of the base]*h/3
area of the base=x²
h=x
[volume of a pyramid]=[x²]*x/3-----> x³/3
so
[volume of a pyramid]=[volume of a cube]/3
the answer is
[volume of a pyramid]=[volume of a cube]/3
The above formulas do not hold for r = 1. For r = 1, the sum of n terms of the Geometric Progression is Sn
n
= na.
(ii)When the numerical value of r is less than 1 (i.e., - 1 < r < 1), then the formula Sn
n
= a(1−rn)(1−r)
(

is used.
(iii) When the numerical value of r is greater than 1 (i.e., r > 1 or, r < -1) then the formula Sn

= a(rn−1)(r−1)
(

(iv) When r = 1, then Sn

Answer:
-If the legs of the triangle added up are bigger than the hypotenuse, its an acute tri.
-if they are smaller then its and obtuse angel
-if the legs added up are = to the hypotenuse, then the triangle Is a right triangle.
your right triangle is:
5,12,13
Step-by-step explanation:
Because 5^2+12^2=13^2
It is true
