Answer:
20 feet
Step-by-step explanation:
If a 6-foot tall man casts a 4.5-foot long shadow, the ratio of height to length is 6:4.5 or 4:3. Thus, since the flagpole shadow is 15 feet tall, we multiply by 4/3 to find the height to be 20 feet.
Hey there!
ASSUMING:
p = 2l + 2w
IF SO:
• We already have our perimeter (p) & our width (w), now you have to find our length (l)
160 = 2l + 2(34)
CONVERT TO:
2l + 2(34) = 160
SIMPLIFY IT:
2l + 68 = 160
SUBTRACT 68 to BOTH SIDES:
2l + 68 - 68 = 160 - 68
SIMPLIFY IT:
2l = 160 - 68
2l = 92
DIVIDE 2 to BOTH SIDES:
2l/2 = 92/2
SIMPLIFY IT:
l = 92/2
l = 46
Therefore, your answer should be:
l = 46
Good luck on your assignment & enjoy your day!

We have that
<span>A).Formulate a recursive sequence modeling the number of grams after n hours.
a(n) = 0.75*a(n-1)
</span>B) .Use the model to calculate the amount of contaminants after the third hour of the experiment.
<span> for the first hour
</span>a(1) = 0.75*a(0)
<span>a0=400 g
a1=(3/4)400 = 300 g
for the second hour
</span>a(2) = 0.75*a(1)
<span>a1=300 g
a2=(3/4)300 = 900/4 g
for the third hour
</span>a(3) = 0.75*a(2)
<span>a2=900/4 g
(3/4)900/4 = 2700/16 = 168.75 g
the answer is </span>168.75 g
