A. 39<br> B. 55<br> C. 66<br> D. 82
kherson [118]

Answer:

D) 82 units

Step-by-step explanation:

ΔBCD ≅ ΔEFG

In congruent triangles, corresponding parts are congruent

BD  = EG

4x - 9 = 2x + 15

4x - 9 -2x = 15

2x - 9 = 15

    2x = 15 +9

    2x = 24

      x = 24/2

      x = 12

EG =  2x + 15 = 2*12 + 15

     = 24 + 15

EG = 39 units

FE = CB =   17 units

Perimeter of ΔEFG = FE + EG + GF

                               = 17 + 39 + 26

                               = 82 units

A slug takes 4.25 minutes to travel 11.2 centimeters. What is the speed of the slug in meters per second?
MAXImum [283]

Answer:

4.39*10^{-4}\ m/sec

Step-by-step explanation:

Remember that

1\ m=100\ cm

1\ min=60\ sec

The speed is equal to divide the distance by the time

Convert the units

4.25\ min=4.25(60)=255\ sec

11.2\ cm=11.2/100=0.112\ m

so

0.112/255=0.000439\ m/sec

4.39*10^{-4}\ m/sec
