Question

Tolongi yang nomor 1,2,8,4,7,10,2,3,4. tolongi ya kakak besok ditumpuk. PAKE CARANYA DAN TDK BOLEH NGASAL JAWAB YG LENGKAP YA (Y)

PLEASE BANGET PLEASE BANGET!!!!!!!!!!!!!!!!!!

Answer 1

1) K trapesium = 20+28+7+7 = 62 cm

2) V prisma = L alas.t
= (1/2.a.t).t
= (1/2.8.6).9
= 24.9
= 216 cm kubik

8) V limas = 1/3.L alas.t
165 = 1/3.L alas.5
165.3 = 5.L alas
495 = 5.L alas
L alas = 495/5
L alas = 99 cm²


4) L trapesium = 1/2.(a+b).t
525 = 1/2.(a+b).25
525.2 = 25.(a+b)
1050 = 25.(a+b)
a+b = 1050/25
a+b = 42 cm

7) jumlah berat badan = 60+75,5+17 3/5 + 42 2/3
= 60+75,5+17,6+42,7
= 195,8 kg


10) A(1,3) ---> sb.y ---> A'(-x,y) = A'(-1,3)
B(4,-3) ---> sb.y ---> B'(-x,y) = B'(-4,-3)


2) alas = 2.L / t
= 2.170 / 17
= 20 cm

3) V limas = 1/3.L alas.t
= 1/3.210.7
= 490 cm kubik

4) (2,1) ---> sb.y ---> (-2,1)
(7,4) ---> sb.y ---> (-7,4)
