Answer:
108°
Step-by-step explanation:
The area of a sector is given by the formula ...
A = (1/2)r²θ . . . . . where θ is in radians
Solving for θ, we find ...
θ = 2A/r²
For your given sector, the central angle is ...
θ = 2(30π cm²)/(10 cm)² = 0.6π . . . . radians
π radians is 180°, so the central angle in degrees is ...
θ = (0.6)(180°) = 108°
The central angle measure of the sector is 108°.
Answer:
D) The value cannot be determined from the information given
Step-by-step explanation:
If 3x−y=12, what is the value of 8x/2y ?
We can progress till:
- 3x-y=12
- y= 3x-12
- 8x/2y= 4x/y= 4x/(3x-12),
we need the value of x to determine the result.
So the answer is the last choice
To solve this we are going to use the kinematic equation for final velocity:

where

is the final velocity

is the initial velocity

is the acceleration

is the time
We know for our problem that the the velocity at the beginning of the slope is

, so

. We also know that the speed ad the bottom of the slope is

, so

. We also know that the acceleration is

, so

. Lets replace those values in our formula and solve for

:





seconds
We can conclude that it takes the roller coaster
3 seconds to reach the bottom of the slope.
You must divide both sides by 3,and you get 3/4.
