Yolanda is buying supplies for school. she buys n package of pencils at $1.40 per package and m pads of paper at $1.20 each. what does each term in the expression 1.4n+1.2m represent? what does the entire expression represent?

To solve this problem,we must first understand what our variables represent. The variable n represents the number of packages of pencils that Yolanda buys and the variable m represents the number of pads of paper that Yolanda buys. We are multiplying these two variables by their respective prices to find out the price of buying multiple packages of pencils and paper.

The term "1.4n" represents the total cost of n packages of pencils.

The term "1.2m" represents the total cost of m pads of paper.

Because we are adding these two terms together, the sum (the entire expression) represents the total cost of both the pencils and the paper.

The expression "1.4n + 1.2m" represents what is discussed above.

Hope this helps!

< 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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
