Step-by-step explanation:
I beleive you just count the dots thats what i did
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:
Step-by-step explanation:
The given equation is:
We have to find the logarithmic equation with same solution as the given equation.
If we take the log of both sides, we can get a logarithmic equation. Since the log operation is applied to both sides the solution of the equation will stay the same.
Taking the logarithm to the base 3 of both sides, we get:
Answer: 2.17 feet
Step-by-step explanation:
First find the circumference of the cycle.
The bicycle made five rotations and that covered 34.02 feet. The rotation (circumference) of the cycle is the single rotation distance:
= 34.02 / 5
= 6.804 ft
Circumference = Pie * Diameter
6.804 = 3.14 * Diameter.
Diameter = 6.804 / 3.14
= 2.17 feet
