Tara used 8 centimeters of tape to wrap 4 presents. how many presents did tara wrap if she used 10 centimeters of tape?

She wrapped 5 presents

Step-by-step explanation:

She used 2cm to wrap each present

8cm = 4x

x is the amount of presents

divide by 4

x= 2 cm

Given 10 cm, divide by 2 to determine amount of x, or presents

< 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

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
