Answer: (total amount paid - $40) / 0.05
Step-by-step explanation:
Given the following :
Monthly fee = $40
Additional fee = $0.05 per minute on phone
Given the the amount paid for the month is available, number of minutes he was on phone can be determined thus :
Total amount to be paid = monthly fee + additional fee
Additional fee = $0.05 × n
Where n = number of minutes on phone
Hence,
Total amount paid = $40 + $0.05n
If the amount paid is known, the number of minutes on phone can be calculated thus;
(Total amount paid - monthly fee) = $0.05n
n = (Total amount paid - monthly fee) / fee per minute on phone
(total amount paid - $40) / 0.05
Step-by-step explanation:
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)
The shape of the pasta is most likely to be a square
Okay so like, all you've gotta do is multiply 567 by 48 & add 1250. Leaving you with the answer of 28,466
Answer:
1 /4
Step-by-step explanation:
Given that :
Number of red = 7
Number of Blue = 7
Number of green = 14
Total number of balls = 28
Probability of picking a ball that is neither red nor green.
Probability = required outcome / Total possible outcomes
P(neither red nor green) = P(picking a blue ball) = 7 / 28 = 1/4
