Answer:
<h3>The height of the Silo is 84 ft</h3><h3>∴
</h3>
Step-by-step explanation:
Given that a 6-foot tall observer casts a 3.5-foot shadow at the same time a silo casts a 49-foot shadow.
<h3>To find the height of the Silo:</h3>
We can solve this by setting up a ratio comparing the height of the Silo to the height of the observer and shadow of the Silo to the shadow of the observer.
Let be height of the Silo
shadow of the Silo
height of the observer
shadow of the observer
Now we have
Substitute the values we get
<h3>∴
</h3><h3>∴ the height of the silo is 84 ft</h3>
Answer:
x=1
Step-by-step explanation:
3(x+2)-10=4x-6+x
3x+6-10=5x-6
3x-5x-4=-6
-2x-4=-6
-2x=-6+4
-2x=-2
2x=2
x=2/2
x=1
