Answer: aₙ = [d-(d-n)]*10
where n is the number of questions answered correctly and d is the total amount of questions.
Step-by-step explanation:
By understanding the question we can tell than she will be rewarded for each corrct answer. so, how many wrong answers she/he can have?
d-n= Total number of wrong answers
d- (d-n) = Total number of correct answers
price: 10 for each correct answer, so:
price: [d-(d-n)]*10
Therefore:
aₙ = [d-(d-n)]*10
Answer:
The length of the longest section x = 36 ft
Step-by-step explanation:
Total length of the wire = 51 ft
Let first section of wire = x
Second section of wire = y
Third section of wire = z
According to given data
x = 3 y & y = 4 z
Total length of the wire = x + y + z = 51
y = 12
x = 3 × 12 = 36
Therefore the length of the longest section x = 36 ft
