Answer:
33.33%
Step-by-step explanation:
We need to calculate the <u>unit selling price and cost of each cosmetics.</u>
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;
x = 1 cosmetic
since 360 = 12 cosmetic
cross multiply
12x = 360
x = 360/12
x = 30
Hence the unit cost price of the cosmetics will be Rs. 30
Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)
Selling price per unit = Rs. 40
Cost price per unit = Rs. 30
percent gain = SP-CP/CP * 100%
percent gain = 40-30/30 * 100
percent gain = 10/30 * 100
percent gain = 100/3
percent gain = 33.33%
Hence the percentage gain is 33.33%
Answer:
The lines are not perpendicular
Step-by-step explanation:
m1=1/2
m2=2
m1*m2=1/2*2=1
Lines are perpendicular when m1 * m2 = -1 because m1 * m2 = 1 these lines are not perpendicular
Answer:
they have 3 dollars left because you add 3.50 plus 2.50 equals 6 then you divide it by 2 cuz 2 people are sharing and they have 5 bucks each which would get you the answer of 3. they have 3 dollars each
Answer:
Hence, only one triangle is possible.
Step-by-step explanation:
Let, ABC is a triangle.
Given that,
first side of a ΔABC is 4, second side of a ΔABC is 3 and ∠B is °.
Diagram of the ΔABC is shown below.
Now,
(Law of sines)
⇒
⇒ =
⇒
⇒ ∠A = 61°
Now, ∠A + ∠B+ ∠C = 180° (angle sum property)
⇒ 61° + 41° + ∠C = 180°
⇒ ∠C = 78°
⇒
⇒
⇒
Therefore, ∠A = 61°, ∠B = 41°, ∠C = 78°,
Hence, only one triangle is possible.
