Answer: C= 10
Step-by-step explanation:
This equation is separable,
Integrate both sides and solve for :
Solve for using the initial value.
Then the particular solution is
Answer:
42%
Step-by-step explanation:
x is for the volume of the container
the amount filled in the first container=0.30x
the volume of the first container + 50% of the second=(x+x*50%)=1.5 x
the amount of acid in the second container= 1.5x * 50%=0.75x
total amount of acid in the third one =0.3x+0.75x=1.05x
total solution : x+1.5x=2.5x
percentage=1.05x/2.5x= 0.42 or 42%
7436 ÷ 13 = 572
I didn't understand the rest of the thing u mentioned
Answer:
5536 calculators
Step-by-step explanation:
We integrate the function dx/dt to obtain the number of new calculators between beginning of the 3rd week and end of week 4. Note that beginning of 3rd week is the same as end of 2nd week. So, =
Let u = t + 12, then = 1. So, du = dt. We also change the limits of our integration. So, when t = 2, u = 2 + 12 = 14 and when t = 4, u = 4 + 12 = 16
Then = ∫₁₄¹⁶ ₁₄¹⁶ =
≈ 5536 calculators
