Answer:
0.05 cm
Step-by-step explanation:
The least-significant digit in the given measurement is the one in the 0.1 cm number place. The "greatest possible error" is half the value of that number place, so is ...
(0.1 cm)/2 = 0.05 cm . . . . "greatest possible error"
_____
For questions of this sort, we make the (not always practical) assumption that the measurement is rounded perfectly to the nearest 0.1 cm.
Answer:
$24.3
Step-by-step explanation:
Tip:
15% of 18 = 0.15 x 18 = 2.7
Cost of Dinner:
Tip + Cost of meal = total price
2.7 + 18 = 20.7
Money Remaining:
Starting value - Cost of Dinner = Amount remaining
45 - 20.7 = 24.3

Answer: n = 75; p = 30
Explanation: (a) 5p + 4n = 450 where p is for pen and n is for notebook.
(b) 10p + 3n = 525
We can use the elimination method to solve these two equations.
1. Multiply the first equation by 2 so that 10p will cancel out:
2(5p + 4n = 450)
- 10p + 3p = 525
10p + 8n = 900
- 10 p + 3n = 525
5n = 375
2. Divide by 5 to get n alone: n = 75
3. Plug 75 into the first equation: 5p + 4(75) = 450
5p + 300 = 450
4. Subtract 300 from 450: 5p = 150
5. Divide by 5 to get p alone: p = 30
We can test if this is correct by plugging our answers into the second equation:
10(30) + 3(75) = 525
300 + 225 = 525
525 = 525
This is a true statement, which means that our answers are correct.
