Answer:
x = Rs 20,833.33
the value of x is Rs 20,833.33
Step-by-step explanation:
Let x,y and z represent the price of the item initially, after one month and after two months respectively.
Given that;
after one month its label price is reduced by 20%
y = x - 20% of x
y = x - 0.20x
y = 0.80x ........1
after 2 months its reduced price is further reduced by 10% and then sold it for Rs 15000.
z = y - 10% of y
z = y - 0.10y
z = 0.90y ........2
Substituting equation 1 into 2;
z = 0.90(0.80x)
z = 0.72x
Also z = Rs 15000
So,
z = 0.72x = Rs 15000
0.72x = Rs 15000
x = Rs 15000/0.72
x = Rs 20833.33333333
x = Rs 20,833.33
the value of x is Rs 20,833.33
the answer is C because Cos is adj/hyp. Since there is only one option that even has cos involved, it must be the correct answer.
The first one! you probably got confused from the top two, they have the same data but the first one would be correct because the number line is in the correct order
I believe it is 72 because there is a right angle so thats 90 the known angle is 18 so thats 18-90-18=72
Answer:
36. m^7
37. x^3 y
38. 6v^5
Step-by-step explanation:
Divide the exponents by the number in the radical sign,
so, If no number is given then divide exponents by 2 eg. question 38
<h3>Explanation </h3>
36. 7√m^49 means m^(49/7) = m^7
37. 3√x^9y^3 means x^(9/3) y^(3/3) = x^3 y
38. √36v^10 means (√36) v^(10/2) = 6v^5 (√36 = 6)
