1. Make sure you explain why and show all your work. In Triangle QRS, X is the midpoint of QR, Y is the midpoint of RS, and Z is the midpoint of QS.
Also, XR = 5, YS = 7, and QS = 20.
What is the perimeter of the Triangle XYZ?

2. Make sure you show all your work for full points.
What is x?
15
58
Z
X
38

The perimeter is 44.  Because we know the midpoints and distance between the sides of XR is half the side and YS is half the other side, those sides are 10 and 14.  QS is a full side already so it is just 20.  20+14+10=44 for the perimeter.  

Number 2 makes no sense, you've omitted something needed there.

Step-by-step explanation:

they are just trying to trick you... by giving you 1/2 of some of the sides and then the whole side on the last one

QR  +   RS  +  QS = perimeter

2(XR) + 2(YS) + QS = perimeter

2(5) + 2(7)  + 20 = perimeter

10 + 14 + 20 = perimeter

44 = perimeter   :)

answer

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
