Step-by-step explanation:
Answer:
0.66 gal.
Step-by-step explanation:
The following should apply:
C1 * V1 = C2 * V2
we have that C1 is 0.1, that C2 is 0.3 and that V1 is equal to 2 gal
replacing the values we have that:
0.1 * 2 = 0.3 * V2
reorganizing the equation we have:
V2 = 0.1 * 2 / 0.3 solving this remains 0.66.
It means that the amount of solution 2 is 0.66 gal.
The answer would be 2. This is because inverse means opposite, and since f(x)=-2, then that means the inverse would be 2.
First you need to find the r, if C=2pieR, than 2.4=2pieR now you divide 2.4 by 2 so you got 1.2=pieR now you divide 1.2 by pie and obtained aproximately 0.38 miles, that is your R, now you do pie multiply by 0.38 exposant 2 and there you go, your answer is aproximately 0.45 miles2 :)
