Answer:
8/24 which is 1/3
Hope that helps:) Brainliest?? Feel free to ask me more questions
Step-by-step explanation:
To solve for this we will be using the formula S = D/T
S = Speed
D = Distance
T = Time
First we need to re-arrange this formula to solve for time
T= D/S
T = 400/230
T=1.74 hours
.74 hours is close enough to .75 that we can say it is 45 minutes
So it is 1 hour and 45 minutes
To write the number is standard form we need to move the decimal point six times to the right, then:
therefore the answer is b.
Answer:
D
Step-by-step explanation:
Answer:
Either, (9+√69)/6 or (9-√69)/6
Step wise:
3x²-9x+1=0-------------------(i)
comparing equation onw with (ax²+bx+c=0), we get,
a=3, b=-9, c=1
now,
using Quadratic Formula,
(-b±√b²-4ac)/2a=x
{-(-9)±√(-9)²-4.3.1}/2.3=x
(9±√81-12)/6=x
(9±√69)/6=x
Taking +(ve) sign Taking -(ve) sign
(9+√69)/6=0 (9-√69)/6=0
∴(9+√69)/6=0 ∴(9-√69)/6=0
[∵They cannot be further solved]
