Answer:
try B
Step-by-step explanation:
the line in graph B has an x intercept of -5 and also passes through (-8,-2)
Answer:
11
or 39.66 units.
Step-by-step explanation:
Use the distance formula!
A. It's is zero or the center of the grid.
B. Go to the first number on the x axis then for the second number go up the t axis.
Calculate the volume, that is easy:
<span>4 x 5 x 2.5 = 50m3 </span>
<span>now, as you did not provided if you use nitrogen in </span>
<span>ntp (normal temperature and pressure - 20c, 1atm) weight is 1.165kg/m3 </span>
<span>or: </span>
<span>stp (standard temperature and pressure - 0c, 1atm) weight is 1.2506 </span>
<span>these are in case of pure nitrogen, as in presented case nitrogen is only 79% we need to change weights to represent that: </span>
<span>ntp - 1.165kg/m3 / 100% x 79% = 0.92035kg/m3 </span>
<span>stp - 1.2506kg/m3 / 100% x 79% = 0.987974kg/m3 </span>
<span>therefore in case of: </span>
<span>ntp, total weight of n2 will be 50m3 x 0.92035kg/m3 = 46.0175kg </span>
<span>stp, total weight of n2 will be 50m3 x 0.987974kg/m3 = 49.3987kg</span>
Answer:
The balance is $256
Step-by-step explanation:
Given
Required
Determine the balance after 20 visits
Represent the balance with b
Represent the visitation with v
The relationship between the given parameters is:
This gives:
Make b the subject
To get the actual balance after 20 visitation;
Substitute 20 for v
Hence:
<em>The balance is $256</em>
