Can someone plz help me. How can you find the inequalities of 11/15 and 5/7. Next 5/9 and 7/13. Next 11/15 and 5/7. Lastly 5/9 and 7/13. PLZ HELP.

Answers

To make this a little clearer, let's give the pairs of inequalities the same denominator:

Question 1:
$(11)/(15)$ ? $(5)/(7)$
First, apply the common denominator to the first fraction:
$((11)/(15))7 \n (11)/(15) * (7)/(7) \n (11*7)/(15*7) \n (77)/(105)$
Do the same for the second: $15( (5)/(7)) \n (5)/(7)* (15)/(15) \n (5*15)/(7*15) \n (75)/(105)$
Nest, compare the two fractions:
$(77)/(105) \ \textgreater \ (75)/(105)$
Therefore:
$(11)/(15)$ > $(5)/(7)$

Question Two:
$(5)/(9)$ ? $(7)/(13)$
Apply the common denominator to fraction one:
$13( (5)/(9)) \n (5)/(9) * (13)/(13) \n (5*13)/(9*13) \n (65)/(117)$
Fraction two:
$9((7)/(13)) \n (7)/(13) * (9)/(9) \n (7*9)/(13*9) \n (63)/(117)$
Evaluate:
$(65)/(117)$ > $<span>(63)/(117)$
Therefore:
$(5)/(9)$ > $(7)/(13)$

The sketch of this crayon represents an irregular polygon. Find the area of the figure.

Answers

The area of the irregular polygon in the sketch is: D. 40.5 cm².

What is the Area of an Irregular Polygon?

To find the area of an irregular polygon, decompose the polygon into known shapes. Find the area of each shape and add all together.

Thus:

The irregular polygon is made up of a rectangle and a triangle.

Area of the irregular polygon = area of rectangle + area of triangle.

= length × width + 1/2(base × height)

Length = 12.5 cm

Width = 3 cm

Base = 3 cm

Height = 2 cm

Area of the irregular polygon = 12.5 × 3 + 1/2(3 × 2)

= 40.5 cm²
