Answer:
25.100
Step-by-step explanation:
The thousandth place is the third digit to the right of the decimal point - tenths is the first, hundredths is the second, thousandths is the third. Since six rounds up and both nines round up, one must round up all of the way from the fourth decimal place to the tenth decimal place.
Answer:
Klorina's rate in still water is 4.5 km/h
Current's rate is 0.5 km/h
Step-by-step explanation:
Let
x km/h = Klorina's rate in still water
y km/h = current's rate
<u>With the current (current helps):</u>
Distance = 10 km
Time = 2 hours
Rate = x + y km/h

<u>Against the current:</u>
Distance = 8 km
Time = 2 hours
Rate = x - y km/h

Divide both equations by 2:

Add these equations:

Subtract these two equations:

Answer:
B = 1320

Step-by-step explanation:
Let A = number of students at Branch A
Let B = number of students at Branch B
If the number of students taking classes at Branch A is 1/4 more than Branch B, then:


If Branch A has 1,650 students, then substitute A = 1650 and solve for B:
