(1/2)(n-4)-3=3-(2n+3)

n = 2

but if it is

Family traveled 25 miles in 1/2 hour. If it’s currently 3:00 pm and the destination is 225 miles away, what time will they arriv

dangina [55]

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Step-by-step explanation:

We have to calculate the speed first to find the time it will take the family to complete the trip.

Given

Distance = d = 25 miles

Time = t = 1/2 hours = 0.5 hours

$Speed =\frac{d}{t}\\=\frac{25}{0.5}\\=50 miles\ per\ hour$

Now,

Distance remaining = 225 miles

Speed = 50 miles per hour

$s=\frac{d}{t}\\t=\frac{d}{s}\\t=\frac{225}{50}\\t=4.5\ hours$

As we see that the time required to complete the journey is 4.5 hours.

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Plz help me I am stuck on this question

tigry1 [53]

The volume of a cylinder is the area of the circular face times the length of the cylinder.

the area of a circular face is
$A=\pi r^2 = \pi\frac{d^2}{4}$

hence the volume is
$V= \pi r^2 L = \pi \frac{d^2}{4} L$

the Length "L" is 36 in
the diameter "d" is 3 in
