Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
The original price would have been 60 dollars because 25%of 60 is 20 so take twenty from sixty and you get forty
Answer:
y= -1/4
y= -0.25
Step-by-step explanation:
5/6y+1= -1/2y+1/4
<em>Subtract 1 from both sides</em>
5/6y= -1/2y-3/4
<em>Add 1/2y to both sides</em>
1 1/3y= -3/4
<em>Divide both sides by 1/3</em>
y= -1/4
y= -0.25
