Answer:
They complete the hill in 8 hours
Step-by-step explanation:
We will need to solve these equations with a system of equations, so we need to isolate one variable in one of the equations and then replace it with another equation. After this, this means that Beatrice alone would construct the hill in 24 hours and Charlie 40. So, after finding the value A we will need to add A with B and C. This would get us . We will then divide
. This will leave with 8h.
A= 7/120h
C=1/40h
B= 1/24h
Answer:
As per the statement;
The moon takes 28 days to orbit around the earth going at a distance of 2,413,000 km
From the above information,
The ratio between Distance and Days is;
then,
the distance it takes for the moon to travel one day of its orbit around the earth we have;
km.
Therefore, the distance in kilometer does the moon cover in 1 day is 86178.57 km
Answer:
=376.8
Step-by-step explanation:
V=n
Where V is the volume , r is the radius and h is the perpendicular height .
r = m=6
h = 10m
n=3.14
v= 3.14 * 6*6 *
=376.8
