Let rs.5 denominations be x , then rs 10 denominations will be 90-x
then total amount 5x + 10(90-x) which is rs.500
5x + 10(90-x) = 500
900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
Answer: The angle's sine is 0.6. Divide the measurement of the side adjacent to the angle with the measurement of the hypotenuse to find the cosine of the angle. Divide the measurement of the opposite side with the measurement of the adjacent side to find the tangent of the angle.
(8*4)xy/ (8*3)yz= 4x/3z
Break apart the each expression to its simpler parts. The 8s cross each other out and you have 4xy/3yz left. Then you cancel the variables that match. The only ones are the ys. Hence the answer is what you have left over and cannot cancel out or reduce
