How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, then answer the question. *

14 groups

Step-by-step explanation:

Given

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

Convert week to days

Convert to multiplication

Hence, there are 14 groups

< 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
