If he traveled x mi by bus, then the time taken using bus is x/40 hours
and therefore, she took (580-x) mi by train, thus the time taken with train was (580-x)/80 hours.
Hence, x/40 +(580-x)/80 = 9.5 hours
80(x/40) +80 (580-x)/80 = (9.5)80
= 2x + 580-x = 760
x= 760-580
x = 180
Thus the train covered a distance of (580-x) =580-180 = 400
Hence, Wendy took 400/80 = 5 hours on the train
Answer:
just look at the decimal after the decimal number is the tenths place the hundreds place and so on if i have to round 567.1092 i would round the nine up to make the zero a one so my rounded answer would be 567.11
Step-by-step explanation:
3 inches and 2 inches, 6÷3 & 9÷3.
12×3=36 so divide 6 by 3 and 9 by 3
Answer: 76
Step-by-step explanation:
The angles are congruent on both sides
The dish illustrates operations on a parabola.
The depth of the parabolish dish is 160 feet.
The bowl is said to be a parabola.
So, we have:
Where:
From the question, the diameter is 160 feet.
So, the radius (r) is:
So, the coordinate of the depth of the parabola would be:
Substitute these values in
So, we have:
Divide both sides by 160
Rewrite as:
Hence, the depth of the parabolish dish is 160 feet.
