Answer:

Step-by-step explanation:
Given
Area of Sector : Area of Circle = 3 : 5
Required
Determine the central angle
The question implies that

Multiply both sides by 5


Multiply both sides by Area{circle}


Substitute the areas of sector and circle with their respective formulas;


So, we have

Divide both sides by 


Multiply both sides by 360


Divide both sides by 5




Hence, the central angle is 216 degrees
Answer: x = 9
Explanation:
Answer:
$46000
Step-by-step explanation:
if x represents the previous years revenue, and they made 35% more than x, we need to find what 35% of x is and then add it to x to get the new total, so the equation becomes:
x + .35x = 62100
1.35x = 62100
x = 46000
You would need to see the rest of the equation to plug in 7 for x. Treat it as y=equation and replace any x with 7.
