Answer:
379,000
Step-by-step explanation:
We first subtract 44 from both sides so that the equation becomes -13x^2 + 17x - 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -17 ± √(17^2 - 4(-13)(-5)) ] / ( 2(-13) )
x = [ -17 ± √(289 - (260) ) ] / ( -26 )
x = [ -17 ± √(29) ] / ( -26)
x = [ -17 ± sqrt(29) ] / ( -26 )
x = 17/26 ± -sqrt(29)/26
The answers are 17/26 + sqrt(29)/26 and 17/26 - sqrt(29)/26.
Answer:
600 seconds
Step-by-step explanation:
In this case we have to calculate the speed;
Speed = Distance/Time
Speed = 100/20 = 5 mph
Next to get our answer we have to calculate the amount of time
Time = Distance/Speed
Time = 3000/5 = 600 seconds
Answer:
3/25
Step-by-step explanation:
Simplify the fraction by using common factors of numerator and denominator. Now, 12% can be written as 12/100.
