Answer:
3.14 square units
Step-by-step explanation:
Circumference of a circle = 2πr
2πr = 6.28
r = 6.28/2π
r = 3.142/π
Area of a circle = πr^2
slot in the value of r
Area of the circle = π( 3.142/π)^2
" = π(9.87/ π^2)
" = 9.87/π
π = 3.14
Area of a circle = 9.867/ (3.14)
" = 3.14 square units
Answer:
1/7 or 14.3%
Step-by-step explanation:
30% of 750 = 225 (females who study chemistry)
60% of 2250 = 1350 (males who study chemistry)
1575 = total students studying chemistry
P (female chemistry student) = 225/1575 = 1/7 (simplified)
1/7 = 14.3%
900 ÷ 72 = 12.5 minutes
Thus the correct answer is option A .
Y = -2x + 6....so we sub in -2x + 6 for y in the other equation
3y - x + 3 = 0
3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 21 = 0
-7x = -21
x = -21/-7
x = 3
now we sub 3 in for x in either of the original equations to find y.
y = -2x + 6
y = -2(3) + 6
y = -6 + 6
y = 0
so ur solution is : (3,0)
