True or false andy has a 40-hour per week job and leaves a
certain radio on all day while he works. this radio
requires 125 watts of electricity. at a price per
kilowatt-hour of $0.10, it costs $0.10 to play the radio
all day.

that would be false because if it cost $0.10 per hore then how would it be $0.10 all day

answer is 4

Step-by-step explanation:

0.10 x 40 = 4.00

the mean and mad

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
