A building casts a shadow 46 feet long.
At the same time, a 36 foot tall flagpole costs a shadow of 9.2 feet long.
To Find :
The height of the building.
Solution :
Since, all readings are taken in same time.
Ratio of height and shadow remains for all objects.
Let, height of building is H.
So,
![\dfrac{H}{46}=\dfrac{36}{9.2}\\\\H = \dfrac{36}{9.2}\times 46\\\\H = 180\ feet](https://tex.z-dn.net/?f=%5Cdfrac%7BH%7D%7B46%7D%3D%5Cdfrac%7B36%7D%7B9.2%7D%5C%5C%5C%5CH%20%3D%20%5Cdfrac%7B36%7D%7B9.2%7D%5Ctimes%2046%5C%5C%5C%5CH%20%3D%20180%5C%20feet)
Therefore, height of the building is 180 feet.

Answer:
He can buy 3.38 pounds of nails and stay under 12 dollars.
Step-by-step explanation:
We need to write an inequality to solve this problem
total amount >= cost per pound of nails * pounds of nails
The total amount is 12 and the cost per pound of nails is 3.55
Let p = number of pounds of nails
12>= 3.55 * p
Divide each side by 3.55
12/3.55 >=3.55p/3.55
3.38028169 >=p
We round to the nearest hundredth
He can buy 3.38 pounds of nails and stay under 12 dollars.
