I do not agree. If you divide 240 by 30, it would be 8 heartbeats, which is absurd. It's impossible for something to survive with 8 heartbeats per 30 seconds.
In order to get the CORRECT answer, divide 240 by 60 seconds.
This would give you 4 heartbeats per second.
Then, multiply it by 30 seconds, which would give you 120 heartbeats.
CORRECT answer: 120
40hours x $11 = $440
3hours x $16.50 = $49.50
$440 + $49.50 = $489.50
Step-by-step explanation:
4x = 112
× = 112 ÷ 4
× = 28
Corresponding angles are equal
y = 28
