Question

Yang tau CARA no 13,14,15 tolong dijawab dengan benar ya :) 25poin buat kalian :)

Answer 1

13.) pl : 90
lt : 36
pt : 40

p * l = 90
l = 36/t

(memakai subtitusi)

p * 36/t = 90
p = 90*t/36
p = 5t/2

p * t = 40

(memakai subtitusi kembali)

p*t = 40
5t/2 * t = 40
= 40 * 2/5
= 8*2
= 16
t =
t = 4

PT = 40
P*4 = 40
P = 40/4
P = 10

Pl = 90
10l = 90
l = 90/10
l = 10

Volume = p*l*t
= 10 * 9 * 4
= 360

maaf hanya bisa menjawab nomor 13 :))
