Answer:
1680, and No
Step-by-step explanation:
Part A: A mockingbird beats its wings 420 times per 30 seconds (half a minute). This means that a mockingbird will beat its wings 840 times per minute. Multiply this by two and you get 1680 times in two minutes.
Part B: Divide the amount of beats in a minute by 60 (because there are 60 seconds in a minute) and you get the amount of times a mockingbird beats it wings per second.
420/30 = 14 times per second
Ariel said it was 0.07 times per second which is incorrect.
Answer:
The slope is 2.
Step-by-step explanation:
6x - 3y = 63
-3y = -6x + 63
y = 2x -21
m = 2
Answer:
just do 3.9*10000=39000
Step-by-step explanation:
Answer:
as the line is parallel we do not change x-4y what we change is the result x = 8 & y = -4 so the result is 8 - 4 (-4) = 24 so the equation is 24
