Answer:
C. 6m
Step-by-step explanation:
The formula for the volume of a cone: V = πr²h/3
Use this formula to solve for the height (isolate h).
226 = (3.14)(6)²h/3 (Given)
226 = (3.14)(36)h/3 (Squared 6)
226 = 113.04h/3 (Multiplied like terms)
678 = 113.04h (Multiplied 3 on both sides)
h = 5.997876858 ≈ 6 (Divided 113.04 on both sides)
Answer:
first do:
60mph * 4 hours= 240mi
Let D = the distance the passenger train has to
travel to catch the freight train
Start a stopwatch when the passenger train leaves
Let t = the time on the stopwatch when they meet
Equation for freight train:
d-240=60t
Equation for passenger train:
d=100t
all together:
100t-240=60t
we can do 100t-60t because they both have (t)= 40t
40t=240 *now divide 240 by 40= 6
THEN do:
D= 100mph x 6= 600mi
They will meet 600 mi from the station
to check:
d-240=60t x 6
600-240= 360
60 x 6= 360
360=360
Answer: -5x-8<-13
Step-by-step explanation:
The slope: 3/5
Y-intercept:-6
I think the correct answer from the choices listed above is option C. The relationship between the area of a rectangle and its width, as width varies and length stays the same, would be that as <span>width decreases, area decreases. Hope this answers the question. Have a nice day.</span>
