12.50 as 12.50 x 5 is 62.50 or as we know 62.50 for 5 we do 62.50/5 to get 12.50
If you eliminate the parentheses, then add mq, you have
... y - p + mq = mx
Then dividing by m gives you the equation for x:
... x = (y - p + mq)/m
Answer:

Step-by-step explanation:
We have been given that a series of 3 separate, adjacent tunnels is constructed through a mountain. Its length is approximately 25 kilometers.
Each of the three tunnels is shaped like a half-cylinder with a radius of 5 meters.
Since we know that volume of a semicircular or a half cylinder is half the volume of a circular cylinder.
, where,
r = Radius of cylinder,
h = height of the cylinder.
Upon substituting our given values in volume formula we will get,






Therefore, the volume of earth removed to build the three tunnels is
.
No because irrational cant be a simple fraction and 9/15
is 0.6
so... it is not irrational
31.51
r=−5
d=19
h<53
