Answer:
25/4 square inches
Step-by-step explanation:
The area of a sector of a circle is given by the formula ...
A = (1/2)r²θ
where r is the radius and θ is the central angle in radians.
For your sector, the area is ...
A = (1/2)(5 in)²(1/2) = 25/4 in²
Let us say ,
x=number of students who passed
y=number of students who failed
total number of students =276
x+y=276..................(1)
We are given 5 times the number of students passed as failed.
x=5y.............(2)
plugging value of x from (2) in (1),
5y+y=276
6y=276
y=46
x=5y=46*5=230
x=number of students who passed=230
Just put your x to equation and you get y.
Ex.
y = -3(-4)+4
y = 12 + 4 = 16
Answer:
MN=4
Step-by-step explanation:
LM+MN=LN
4x+2+3x-5=5x+3
7x-5x=3+3
2x=6
x=3
MN=3x-5
MN=9-5=4
MN=4
