They need 5 1/4 cups of batter. Because 6 3/4 + 5 1/4 = 12. Hope this helped :P
It is the vertex of the triangle
We know that
with
scale factor 1=1 in/4 m
<span>the longer side of the ballroom-------> 44 m
scale factor= measure model/measure actual
measure model=scale factor*measure actual
</span>measure model=(1/4)*44------> 11 in
with
scale factor 2=1 in/7 m
measure actual=measure model/scale factor
measure actual=11/(1/7)-----> 77 m
the answer is
77 m
3 to the square root of 5
When we are multiplying the two numbers, we should notice that they share the same base. Because of this, we can add the exponents when we multiply them.
