Answer:
the answer is 5.8
Step-by-step explanation:
divide numerator (8) by the denominator (10):
8 / 10 = 0.8
add this value to the integer part: 5 + 0.8 =
5.8 So,
5 8/10 = 5.8
Answer:
Siobhan is making a total of $9.12 per hour.
Step-by-step explanation:
James makes $8 an hour.
Priya makes 20% more, so:
8.00 + 20% = $9.60
Siobhan makes 5% less, so:
9.60 - 5% = $9.12
Thus, the answer is $9.12.
Answer:
Step-by-step explanation:
1) 15% of 75 = (15/100) * 75 = 0.15*75 = 11.25
2) 7% of 980 = 0.07 * 980 = 68.6
3) 45%of 62 = 0.45 * 62 = 27.9
4) 22% of 198 = 0.22 * 198 = 43.56
It is important to notice firs of all that the train with no stop acceleration and them no stop acceleration would have a faster travel between stops. given this is safe to assume that there is a period during while the train is not accelerating nor decelerating. To find the time that is speed is constant
let's assume non-stop accelerating and decelerating and the time lost (subtraction of both) is the time the train had constant speed:
assuming same time accelerating a decelerating we have that the distance is
x = voT + 1/2aT^2 (initiial speed = 0) (0.25 miles = 1320 feets)
1320 = 1/2 (8)(T/2)^2
T/2 = 18.17 seg
T = 36.34 seg
time of constant speed
T = 41 -36.34 = 4.66 seg
maximum speed
v = v0 + aT (initial speed = 0)
v = 8(18.17) (time accelerating)
v = 145.36 feets/sec
distance at full speed
x = v*t
x = 145.36*4.66 = 677.38 feets
