BHF= 106
HGD=106
EGD = 74
EGC= 106
May be wrong but hope this helped!
Let x be the lowest positive number Then the other number = 5x.
So 5x - x = 72
4x = 72
x = 18
So the numbers are 18 and 90 answer
The second one because 1/4 times 3/3 equals 3/12
40% of a given number is 8...
0.40x = 8
x = 8 / 0.40
x = 20....so 20 is the given number
what is 15% of 20...
0.15(20) = 3 <==== ur answer
We want to know when we brought it back in to the room. at that time
the temperature difference is 80 - 42 = 38 so we have to solve
<span>
38=9<span>e<span>^−.3344t</span></span></span> for t
this time we get
<span><span>38 / 9</span>=<span>e^<span>−.3344t</span></span></span>
<span>t=<span><span>ln(<span>38 / 9</span>)</span><span> / −.3344</span></span></span>
<span>t=−4.3</span>
so 4.3 minutes before 2:10
