Answer:
105.9912 liters of wine can be held in a wine barrel whose capacity is 28.0 gal.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
Let x be the liters of wine can be held in a wine barrel whose capacity is 28.0 gal.
Given that:
1 gal = 3.7854 l
then
by definition of proportions;

By cross multiply we get;
liters
Therefore, 105.9912 liters of wine can be held in a wine barrel whose capacity is 28.0 gal.
Answer:
x=3 meters
Step-by-step explanation:
step 1
Find the area of the rectangular pool

we have

substitute

step 2
Find the area of rectangular pool including the area of the walkway
Let
x ----> the width of the walkway
we have

substitute

step 3
Find the area of the walkway
To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway
so

step 4
Find the value of x if the area of the walkway equal the area of the pool
so

Solve for x

Solve the quadratic equation by graphing
The solution is x=3 meters
see the attached figure
No because if it is a square all the sides are 7m long so a 9m plank will not fit. Hope this helps.
