The correct answer is this one: "C. 5+5=10 "
From the equation 6 + 5 = 11
We can have the doubles : 5 + 5 + 1 = 11
<span>The doubles plus one are the facts in which one addend is larger than the other by one.</span>
Here are the choices.
A- 8+8=16 B- 7+7=14
C- 5+5=10 D- 4+4=8

Answer:
0.6625
Step-by-step explanation:
To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,
Area of square is A=s*s=0.25*0.25=0.0625.
Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.
There are four equal triangles so together there area is 4*0.15 = 0.60.
Add the square to it and you have the surface area of the pyramid.
0.0625 + 0.60 = 0.6625
