Perform the indicated multiplication:
<span>7p-(3p+4)= -2(2p-1) + 10
becomes
7p - 3p - 4 = -4p + 2 + 10
Group like terms:
7p - 3p + 4p = 2 + 10 + 4
8p = 16 => p = 2 (answer)</span>

The
equation of velocity of sound in air is v = 20 √(273 + t). In this problem, we
need to find the temperature when the velocity is 329 meters/s. You need
to measure the time it takes a sound to travel a
measured distance in order to measure its speed in air.
Given:
Velocity
of sound in air equation = v = 20 √(273 + t)
Velocity
= 329 m/s
To
solve:
V = 20 √(273 + t)
<span>
329 = 20 * sqrt(273 + t)</span>
<span>
16.45 = sqrt(273 + t)</span>
<span>
273 + t = 16.45^2</span>
<span>
t- 16.45^2-273</span>
<span>
t = -2.4 degrees Celsius</span>
<span>So, the
temperature when the velocity is 329 meters per second is -2.4 degrees Celsius.</span>
Summary of information:
total output = 3600 units per year
split into 18 equal orders
cost per order = $40
cost to store a unit for one year = $20
lead time (i.e. storage before shipping) = 5 days
Solution:
quantity split into 18 orders, so 3600/18= 200 units per order.
Order cost = $40 * 18 orders = $720 ..........................(A)
Storage cost:
Each order has 200 units, stored for 5 days = 200*5=1000 unit-days
storage needed for 18 orders = 1000*18 = 18000 unit-days = 50 unit-years
Total storage cost = 50 unit-years * $20 / unit year = $1000...........(B)
Total ordering cost = (A) + (B) = $720+$1000 = $1720
7/2+3/9=
(7+3)+(0.2+0.9)=
10+1.1=11.1
