b
The amount of salt in the tank after 4 hours is gotten by simply replacing t in the equation from a, with 4 hours. Since the t gotten in a above is in minutes, we'd convert hours to minute as well. If we do that, we have
t = 4 hours = 4 * 60 minutes = 240 minutes
y = 160/3 (1 - e^((-3 * 240)/200))
y = 160/3 (1 - e^(-720/200))
y = 160/3 (1 - 0.0273)
y = 160/3 (0.9727)
y = 51.877 kg
Therefore, the amount of salt in the tank after 4 hours is 51.877 kg
Answer:
a. 125
b. 25/64
c. 0.25
d. 343
e. 49/4
f. 0.81
Step-by-step explanation:
multiply by the same number by the amount of times the power tells you
b. 5*5 = 25 8*8= 64
c. 5*5 = 25 0.5*0.5 = 0.25
d. 7*7*7 = 343
e. 7*7 = 49 2*2= 4
f. 9*9 = 81 0.9*0.9= 0.81
Answer: 
Step-by-step explanation:
You need to convert from mixed number to decimal number.
In order to do this, you can follow the steps shown below:
1. You must divide the numerator of the fraction by the denominator of the fraction.
2. Now you must add the quotient obtained to the Whole number part.
Then, you get:
Then, the scale image that maps "Figure A" onto "Figure B" is:
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by 
.
Therefore, the result is:
