Hi there!
To covert any decimal number,
Multiply the Decimal Number by 100, and put the " % " sign .
Accr'ding to the question :-
• 0.255 × 100 = 255 = 255 %
Hence,
Option [ A. ] - 255 % is Correct.
~ Hope it helps!
Answer: (D) ![\frac{y-x}{y+x}](https://tex.z-dn.net/?f=%5Cfrac%7By-x%7D%7By%2Bx%7D)
Explanation:
![\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}=\frac{y-x}{y+x}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7Bx%7D-%5Cfrac%7B1%7D%7By%7D%7D%7B%5Cfrac%7B1%7D%7Bx%7D%2B%5Cfrac%7B1%7D%7By%7D%7D%3D%5Cfrac%7B%5Cfrac%7By-x%7D%7Bxy%7D%7D%7B%5Cfrac%7By%2Bx%7D%7Bxy%7D%7D%3D%5Cfrac%7By-x%7D%7By%2Bx%7D)
Just a note on writing down these expressions: I recommend using parentheses whenever you can to avoid misinterpretation. An expression 1/x-1/y / 1/x+1/y could be interpreted by someone as 1/x-(1/y / 1/x)+1/y, which is a different thing.
Answer:
57.6°
Step-by-step explanation:
It is always helpful to draw a picture. Also, you need to memorize all the definitions of the trig functions. For example,
sine of an angle = opposite side/hypotenuse
In your case, SQ is opposite side to angle R and QR is the hypotenuse
Therefore, sin R = 6.5/7.7
m∠R = arcsin (6.5/7.7) = 57.6°
Answer:
parallel refers to two equidistant lines, Because the lines are equally distant, they have the same slope and the angle between them is zero. On the other hand, when two lines intersect at a right angle, they are called perpendicular.
