Answer:
The ratio of perimeter of ABCD to perimeter of WXYZ =
Step-by-step explanation:
First, we have to determine the multiplicative factor of the dimensions for both figures.
Considering sides AB and WX,
multiplicative factor =
= 1.5
So that:
XY = 6 x 1.5 = 9
YZ = 7 x 1.5 = 10.5
ZW = 7 x 1.5 = 10.5
Perimeter of ABCD = 6 + 7 + 7 + 8
= 28
Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of the two quadrilaterals can be determined as;
ratio =
=
=
The ratio of the perimeter of ABCD to perimeter of WXYZ is .
Answer:
a) 4 -
b) 1 -
c) 6 -
Step-by-step explanation:
It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.
We start with:
We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):
Then we multiply each side by 2 to get rid of the 1/2, answer #1:
Finally, we divide each side by t^2 to isolate a (answer #6):
