Since you can spend all but 20%, then you can spend the rest, namely the 80%.
whatever% of anything is just (whatever/100) * anything.
therefore, 80% of 225 is then (80/100) * 225, that much.
The length of pendulum is 2.485 feet
<h3><u><em>
Solution:</em></u></h3>
Given that,
The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth
<u><em>Therefore, the given formula is:</em></u>

We have to find the length of pendulum that makes one full swing in 1.75 seconds
So the modify the given equation to find "L"

Substitute T = 1.75 seconds and 

Thus length of pendulum is 2.485 feet approximately
9(millions), 9(hundred-thousands)9(ten-thousands)9(thousands), 9(hundreds)9(tens)9(ones).
The second store is cheaper. It is only 18.99 per gallon. Just divide the costs by 2.
Answer:
The number of cows and calves Mitchel can transport is determined by the inequity 
Step-by-step explanation:
Let
be the number of goats, and
be the number of cows. If Mitchel's livestock trailer can only hold maximum of 5000 pounds. then we have the inequality
<em>(this says that the weight of the goats and the calves cannot exceed 500 pounds.) </em>
Therefore, this inequality determines the number of goats and calves Mitchel can take in a single trip.
