It can be
scientific notation is defined as
(number greater than or equal to 1 and less than 10) times 10^x whre x is the number of places the decimal must be moved to the right to return it to the original value (if it must be moved to the left, make it negative)
if we have
2.3
in sciefitific notation, 0 places must be moved so it would be written as
2.3 x 10⁰
so yes, 0 can be an exponent, tho it would not be helpful and would just be more work
I’m so sorry but I need to answer 2 questions to be able to ask mine again I apologize
Answer: the system of equations are
x + y = 35
3x + 2y = 100
Step-by-step explanation:
Let x= the number of short answer questions.
Let y= the number of multiple choice questions.
Noah wants 35 questions on the exam. This means that
x + y = 35
He plans to mix short answer questions, worth 3 points, with multiple choice questions worth 2 points. This means that x short answer questions will give 3x points and y multiple choice questions will give 2y points
Since the exam is worth 100 points, then,
3x + 2y = 100 - - - - - - - -1
Substituting x = 35 - y into equation 1, it becomes
3(35 - y) + 2y = 100
105 - 3y + 2y = 100
y = 105 - 100 = 5
x = 35 - y = 35 - 5
x = 30
