Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
Let x be the height of the building.
Multiply both sides by 139.
Therefore, the building is 75.8 feet long.
Answer:
;
Step-by-step explanation:
Given
Every other minute
Required
Determine the recursive function
Let the number of minutes be represented with n.
The initial condition can be represented as:
--- i.e. 3 friends initially at the first minute
At every other minutes:
i.e 2 minutes upwards
This means that n follows the following sequence
Note that the difference between each term is 1.
This means that recursive function has to be defined backwards i.e.
Where k = 2
i.e. The number of friends that received the video from each friend
So, we have:
Hence, the recursive function is:
;
Answer:
The error interval for x is:
Step-by-step explanation:
In order to determine the error interval for x, We have to get the all the number which could be rounded off to 7.42 .
These number can be listed in order such as:
7.415 7.416 7.417 7.418 7.419
Therefore, the error interval for x is:
Answer:
here's the answer -2gf

Hi there!
Using some simple conversions we can determine how many quarts are in 2 & a half gallons.
1 gallon = 4 quarts.
2 gallons = 8 quarts.
Since we're trying to determine how many quarts are in 2 & a half gallons we can separate our problem into how many quarts are in two gallons and how many are in a half a gallon.
2 gallons = 8 quarts.
.5 gallon = 2 quarts.
After adding this together we come up with the answer that there are 10 quarts in 2 & a half gallons. :)
