Answer:
The measure of an arc refers to the arc length divided by the radius of the circle. The arc measure equals the corresponding central angle measure, in radians. That's why radians are natural: a central angle of one radian will span an arc exactly one radius long.
Answer:
10%
Step-by-step explanation:
Given: CP of lemon is $600.
3/4 of lemon sold at 20% loss
Remaining lemon at 20% gain.
Considering the quantity of lemon remain constant.
Cost price of 3/4 of lemon=
As given, 3/4 of lemon sold at 20% loss.
∴ Selling price of
Selling price=
Hence, selling price of 3/4 lemon is $360.
Now, the cost price of remaining lemon
∴ The cost price of
As given, remaining
∴ Selling price of
Selling price of
Hence, selling price of 1/4 lemon is $180
Loss\profit percent=
∴ Loss\profit percent=
Hence, the loss percentage is 10%
-To simplify fractions.
Ex. (2x+10)/2 we factor 2 to simplify so 2(x+5)/2=x+5
Answer:
5/3 x + 15
Step-by-step explanation:
The inverse of a function is the reflection across the line y = x. As such, algebraically it is found by switching y and x in the equation and isolating to solve for y.
g(x) = 3/5 x - 9
x = 3/5 y - 9
x + 9 = 3/5 y
5(x+9) = 3y
(5x + 45)/3 = y
5/3x + 15 = y
