<span>E = {x|x is a perfect square between 1 and 9} = {1,4
</span><span>F = {x|x is an even number greater than or equal to 2 and less than 9}
</span><span>D = {x|x is a whole number}

answer
D ∩ (E ∩ F) = 4
Answer:
25/29
Step-by-step explanation:
see the attached picture.
Answer:
1% of 4000 + 4% of B = 2% of (4000 + B)
40 + 0.04*B = 0.02( 4000 + B)
40 + 0.04* B = 80 + 0.02*B
40 + 0.04*B - 80 - 0.02B = 0
0.02*B - 40 = 0
0.02*B = 40
2B = 4000
B = 2000
Step-by-step explanation:
Ok
relation of diameter to radius
2 radius=1diameter
radius=1/2 diameter
2r=d
d/2=r
circumfernce=2pir
since 2r=d
circumference=2d
so
c=pid=2pir
so if ou have circunference and you want to find diameter and radius
c=pid
divde both sides by pi
c/pi=d
c=2pir
divide both sides by 2pi
c/(2pi)=r
so
r=c/(2pi)
d=c/pi
