A bridge can hold at most 80,000 pounds. A tow truck weighing 7,000 pounds is broken down on the bridge. If the average car weights 2,800 pounds, how many cars can safety be on the bridge with the broken down tow truck.

26

Step-by-step explanation:

x = number of cars that an safety be on the bridge with the broken down tow truck.

The equation that can be used to determine the answer =

total weight the bridge can accommodate = total weight of truck + total weight of cars

total weight of cars = weight of a car x total number of cars

2800x

80,000 = 7000 + 2800x

collect like terms

80,000 - 7000 = 2800x

73,000 = 2800x

x = 73,000 / 2800

x = 26

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

< 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
