Answer:
How far should he ride on each of the four days to reach his goal?
1st day: 
miles
2nd day: 
miles
3rd day: 
miles
4th day: 
miles
Step-by-step explanation: As the problem says, 
is the number of miles he rides on the first day. Let's start off with that.
1st day: miles
He want to ride 1.5 times as far as he rode the day before... no 1.5 more, but 1.5 <em>times</em> as far as he rode the day before; you would multiply 1.5 with the previous day's length.
2nd day: 
Then you multiply 
to to get the third day's.
3rd day: 
4th day: 
----------------------------
Phew! Gavin wants to ride a total of 65 miles over these four days, so if Gavin added all the miles of the four days, he should get 65...
1st+2nd+3rd+4th=65
Yes! Now that we've got the hard part done... substitute 8 for ever single .
1st day: miles
2nd day: 
miles
3rd day: 
miles
4th day: 
miles

Checking my answer:
Just add the miles!

Answer:
dh/dt = 0,07 ft/min
Step-by-step explanation:
The swimming pool has the shape of right circular cylinder, therefore its volume is
V(c) = π*x²*h
Where x is the radius of the base and h the height
We take differentiation on both sides of the equation to get:
dV/dt = π*x²*dh/dt
The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.
Then:
8 = π*x²*dh/dt
dh/dt = 8 / π*x²
dh/dt = 8/113,04
dh/dt = 0,07 ft/min
HEY THERE !!
GIVEN :- Maria has 14 pencils, Ted has 9 pencils, Tom has 12 pencils, Lucinda has 13 pencils, and Jumana has 12 pencils.
The sum of all pencils are 60 and the number of persons are 5 .
So 60/5= 12
The no. of pencil which every person has after redistribution is 12 .
HOPE IT HELPED YOU.
Weight = k/(distance)². Let's find the value of k when distance = earth radius:
180 = k/(3900)² → k = 180 x 3900² → k = 2,737,800,000
If he is at 325 miles ABOVE the earth, the distance becomes: 3,900+325=4,225 miles and his weight becomes:
Weight = k/(distance)² → Weight = 2,737,800,000/(4225)² = 153.37
Weight = 153.37 lb
