Answer:
Alignment Heuristic parameters.
Step-by-step explanation:
The students' cognitive maps shows them in a straight row because the students have used "Alignment Heuristic" parameters.
180-96= 84
That means 8x+12=84
84-12=72
That means 8x=72
72÷8=9
therefore X=9
Bob is x yrs old
Sister is x+6 yrs old
X+X+6=32
2X+6=32
2X=32-6
2X=26
2X/2=26/2
X=13
Bob is 13 yrs old
Sister is 13+6 yrs
= 19 yrs
13yrs+19yrs = 32 yrs
Now its 100% accurate
False. Perpendicular lines run beside each other not through each other.
Answer:
1636 cm^2
Step-by-step explanation:
cut in itwo two shapes a rectangle and isosceles trapizoid
Area - 1/2 hight(base x length)
1/2 x 14(6x17) = 714 cm^2
Area of rectangle- 2(wl x hl x hw) = 922 cm^2
l = 17
w = 13
h = 8
add the areas - 922 + 714 = 1636 cm^2
