0.009 is a decimal and 0.9/100 or 0.9% is the percentage for 9/1000.
Step-by-step explanation:
a tree casts a 25-foot shadow on sunny day. If the angle of elevation from the tip of the shadow to the top of the tree is 32 degree, what is the height of the tree to the nearest tenth of a foot?
Tan(32)=H/25
0.624869=H/25
H=.624869 X 25
H=15.6 feet-Height of the tree.
8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
