Answer:
<em>IJ = 82</em>
Step-by-step explanation:
IJ≅IH so they are the same length
IH = 82 = IJ
H=Hayden's toys

The ricipricals are 3/8 and 2/13
<h3>
Answer: 112.5 square units</h3>
Work Shown:
A = area of the triangle
A = base*height/2
A = 9*7/2 = 63/2 = 31.5 ... see note1 below
B = area of rectangle
B = base*height
B = 9*3 = 27
C = area of parallelogram
C = base*height .... see note2 below
C = 9*6 = 54
If you're confused where I got the 6 from, check out the attached image below.
D = total area of the composite figure
D = A+B+C
D = 31.5 + 27 + 54
D = 112.5
-------------------------
note1: The vertical component of the triangle is 9 units because this is part of the rectangle. The rectangle has opposite sides that are the same length. The parallelogram's vertical sides are 9 units long as shown by the single tickmark.
note2: a rectangle is essentially a special case of a parallelogram. In other words, a rectangle is a parallelogram with 4 right angles. So this is why the formula "area = base*height" shows up identical for both rectangles and parallelograms. Keep in mind that the height is always perpendicular to the base. You will not use the segments marked with double tickmarks.
Answer:
300
Step-by-step explanation:
when rounding to the nearest 10,
132 is 130
68 is 70
42 is 40
and 78 is 80
add them all and it is 320
which then that could be rounded to 300.
