Answer: 610,416 lb
<u>Step-by-step explanation:</u>
Volume of a cylinder (V) = π r² · h
V = π (12)² · 30
= 4320 π
Density = Volume x weight
= 4320 π · 45
= 194,400 π
≈ 610,416
It would be the 2nd object or letter B
By the external angle theorem
5x = (5x - 30) + m < RST
m < RST = 5x - 5x + 30 = 30
also m < STR = m < SRT = 5x - 30
So as there are 180 degrees in a triangle:-
5x - 30 + 5x - 30 + 30 = 180
10x = 180 +30+30-30 = 210
x = 21 answer
Answer: 23.5m
Step-by-step explanation:
Answer:
$40
Step-by-step explanation:
100% - 20% = 80%
80% of $50 = 0.8 × $50 = $40
