29/3
or 9.6666666666666666666666666
Step-by-step explanation:
5+24= 29
then divide by 3
Answer:
Step-by-step explanation:
concentration = amount of salt/solution
A) Initial concentration= 90/1000 = 0.09
Q = quantity of salt
Q(0) = 90 kg
Inflow rate = 8 l/min
Outflow rate = 8 l/min
Solution = 1000 L at any time t.
Salt inflow = 0.045 * 8 per minute
= 0.36 kg per minute
This is mixed and drains from the tank.
Outflow =
Thus rate of change of salt
Q'(t) = inflow - outflow =
Separate the variables and integrate
Use the fact that Q(0) = 90
90 = 360-A
A = 270
So
B) Q(t) = 360-270e^-0.004 = 91.07784
C) When t approaches infinity, we get
Q(t) tends to 360
So concentration =360/1000 = 0.36
Answer:
<em>x</em> = 2
Step-by-step explanation:
Given data: The two triangles in the diagram are similar.
AB = 10 cm, AC = <em>x</em> cm, AE = 15 cm, AD = 3 cm
By similar triangles property,
Do cross multiply
⇒ 10 × 3 = 15 × <em>x
</em>
⇒ 30 = 15<em>x</em>
⇒ 30 ÷15 = 15<em>x</em> ÷ 15 (By division property of equality)
⇒ <em>x</em> = 2
Hence, the possible value for<em> </em><em>x</em> is 2.
Answer:
6. im not sure though
Step-by-step explanation:
because if he picks 4 orange and 3 are green, then it means you multiply by 2 because 4*2=8, SO 3*2=6. again, im not sure if its right or not.
