Answer:
18
Step-by-step explanation:
25% of 72
25% = 0.25
Multiply
0.25 * 72
18
Hope this helps :)
Take all three trial result averages and add them up
Then take that number and divide by three because there was three numbers added.
That number is the average of the three trials
Angle of elevation.
<span>On the first, the 456 is the opposite leg and the 837 is the adjacent to the angle of elevation so use tangent (from soh cah toa); x = the angle measure </span>
<span>tan x = 456/837 </span>
<span>inverse tan (456/837) = x so do that on your calculator (be sure it is in degree mode). </span>
<span>Then for Ramsey, 1453 is opposite leg and 2960 is adjacent so you have tan x = 1453/2960 and do like the first one.</span>
X/8=15/12
X=10
The answer Is 10

Solution (4, -12)</h3>
<em>None of the listed choices are a solution</em>
Step-by-step explanation:
y = 4x - 28
y = 1.5x - 18
Set the equations equal since both equal y
4x - 28 = 1.5x - 18
Subtract 1.5x from both sides
2.5x - 28 = -18
Add 28 to both sides
2.5x = 10
Divide both sides by 2.5
x = 4
---------------------
use x= 4 in either equation
y = 4x - 28
y = 4(4) - 28
y = 16 - 28
y = -12
--------------------
Solution (4, -12)
