Divide the current beats per minute by the percentage to get the original beats per minute.
= 10 beats ÷ 20%
= 10 ÷ 0.20
= 50 beats per minute
Check:
= 50 beats * 20%
= 50 * 0.20
= 10
Hope this helps! :)
Answer:
70ml
Step-by-step explanation:
concentrate is half of water ( 140/2=70)
3 parts of 70ml in total (210ml )
2 parts of water-----------70+70 of water= 140
1 part of concentrate 70 of concentrate
Observe that
|√3 + i| = √((√3)² + 1²) = √4 = 2
and
arg(√3 + i) = arctan(1/√3) = π/6
so that
√3 + i = 2 exp(i π/6)
By de Moivre's theorem, we get
(√3 + i)⁶⁰ = 2⁶⁰ exp(i π/6 • 60) = 2⁶⁰ exp(i 10π) = 2⁶⁰
You would need 24 machines
Because 1 machine makes 5 envelopes per minute so simultaneously 24 machines can make 120 envelopes per minute.
Three possible points are:
(-3, 0)
(0, 2)
(3, 4)
To find any points, simply select any value for x. Input that value, then find the corresponding y-value.
For example, if x = 0, then:
-3y = -2(0) - 6
-3y = -6
y = 2
