706 ÷ 0363
1.94490358127 is your answer.
Answer:
b
Step-by-step explanation:
Surface of the earth =3959×3.14
=12,437.565
if 20%is suitable so we multiply it by the surface
12,437.565×0.2=2,487.513 per people
2,487.513/7,700,00,00
So I think it will be the closest to b
For this case, we have that by definition, the circumference of a circle is given by:
Where:
d: Is the diameter of the circle given by 2r, that is, twice the radius.
If we have a circle with a diameter equal to 8cm, then the circumference is given by:

Option C
Answer:
Q=(1,-5)
R=(5,-5)
S=(2,-7)
Step-by-step explanation:
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
