Find the perimeter of triangle cde. round to the nearest tenth.

(1 point)
90.0
18.0
14.3
10.5

18.0

Step-by-step explanation:

The distance formula to find the distance between two points P(a,b) and Q(c,d) is :_

From the graph, the coordinates of ΔCDE are C(-3,1) , D(1,4) and E(3,-2).

Then, length of CD :-

Length of DE :-

Length of EC :-

Now, the perimeter of triangle :_

Hence, the perimeter = 18.0 units

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
