Answer:
.
Step-by-step explanation:
It's kind of not C.
Solve this proportion for 'x':
3/50 = x/2400
Hint: Cross-multiply the proportion, then do what you need to do.
Answer:
3.5 hours
Step-by-step explanation:
Ediburgh -------------------------------350 miles-------------------------London
Let the distance traveled by train from Edin to London be "x"
hence the distance traveled by train from London to Edin would be "350-x"
- The rate of Edin to London train is 60
- The rate of London to Edin train is 40
Let the time they meet be"t"
Now, we know distance formula to be D = RT
Where
D is distance
R is rate
and
T is time
<u>Train from Edin to London:</u>
x = 60t
<u>Train from London to Edin:</u>
350-x = 40t
Solving for x:
350 - 40t = x
We put this into first equation:
x = 60t
350 - 40t = 60t
350 = 100t
t = 350/100
t = 3.5
They meet after 3.5 hours
Answer: 20/3 square inches
Step-by-step explanation:
Area = length*width
length = 5 in.
width = 4/3 in.
A = 5 * (4/3) = 20/3 in^2
Complete Question
If minor arc AB measures 9 inches, what is the length of the radius of circle C? Where the radians is 0.75 radians
If necessary, round your answer to the nearest inch. 6 inches 12 inches 18 inches 24 inches
Answer:
12 inches
Step-by-step explanation:
The formula for Arc length =
Arc length = r θ
θ = 0.75
Arc length = 9 inches
Hence:
r = 9/ θ
r = 9/0.75
r = 12 inches
