Given that,
An expression : 
To find,
The value of the above expression when e = 12 and f = 1/2
Solution,
We have,
Put e = 12 and f = 1/2
So,
So, the value of the above expression is 1.
It is in need of ignoring the absolute value sign when solving differential equations because they may interfere with the solution or in a way that the values that are being calculated may have a different answer in which is not the right answer to the given equation.
Answer: 4 science questions and 5 math questions
<u>Step-by-step explanation:</u>
To guess, you know that no matter how many 10 point questions you answer, the result will end in a zero. The number given is 85 so find a number you can multiply by 9 that ends in a 5. Answer: 9(5) = 45
The remaining points (40) are divisible by 10.
40 ÷ 10 = 4
Check: 5 (9-point questions) + 4 (10-point questions) = 9 total questions
45 points + 40 points = 85 points
Note that this problem can be solved mathematically by setting up a system of equations:
Points: 9x + 10y = 85
Quantity: x + y = 9
Answer:
LM = LN + MN [ assuming N is a point between L and M ]
then find MN:
5. a.) 8.73/450x100=1.94
b.) 8.73/450≈0.02
c.) 450/8.73x25≈1289
7 a.) 622/12≈52km per hour
b.) 622/0.5=1244 km per hour ( that's .......impossible...)
Those are your answers.
