Answer:
Rs. 7245
Step-by-step explanation:
Given parameters:
Cost price = Rs. 6300
Percentage profit = 15%
Unknown:
Selling price = ?
Solution:
If profit is made on a trade, the selling price is higher than the cost price.
Profit = Selling price - Cost price
To find the selling price simply;
Selling price =( 1 +
) x cost price
Selling price = 1.15 x 6300 = Rs. 7245
Answer:
Answer = Option A;
sinθ = ±![\frac{\sqrt{33} }{7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B33%7D%20%7D%7B7%7D)
tanθ = ±![\frac{\sqrt{33} }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B33%7D%20%7D%7B4%7D)
Step-by-step explanation:
cosθ = ![-\frac{4}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B7%7D)
Remove the negative sign and evaluate cosθ = 4/7
cosθ = adjacent/hypotenuse.
Please see attached image for the right-angle triangle representation.
Let opp = length of opposite side of the triangle.
Let adj = length of adjacent side of the triangle.
Let hyp = length of hypotenuse side of the triangle
Using Pythagoras theorem,
![hyp^{2}= opp^{2} +adj^{2} ;\\\\7^{2}= opp^{2}+ 4^{2};\\ \\opp^{2} =7^{2}- 4^{2} \\\\opp^{2} = 49-16\\\\opp^{2} = 33;](https://tex.z-dn.net/?f=hyp%5E%7B2%7D%3D%20opp%5E%7B2%7D%20%2Badj%5E%7B2%7D%20%3B%5C%5C%5C%5C7%5E%7B2%7D%3D%20opp%5E%7B2%7D%2B%204%5E%7B2%7D%3B%5C%5C%20%5C%5Copp%5E%7B2%7D%20%3D7%5E%7B2%7D-%204%5E%7B2%7D%20%5C%5C%5C%5Copp%5E%7B2%7D%20%3D%2049-16%5C%5C%5C%5Copp%5E%7B2%7D%20%3D%2033%3B)
Take the square root of both sides.
±![\sqrt{33}](https://tex.z-dn.net/?f=%5Csqrt%7B33%7D)
opp = ±![\sqrt{33}](https://tex.z-dn.net/?f=%5Csqrt%7B33%7D)
sinθ = opposite/hypotenuse
sinθ = ±![\frac{\sqrt{33} }{7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B33%7D%20%7D%7B7%7D)
tanθ = opposite/adjacent
tanθ = ±![\frac{\sqrt{33} }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B33%7D%20%7D%7B4%7D)
Okay move the decimal 2 times to the right
230/100
Divide both denominator and numerator by 10 so now it’s 23/10
23/10 simplified is 2 3/10 as a mixed number
Hope this helped! Have a nice day or night :)
