Answer:
The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is
.
Step-by-step explanation:
We are given the area of an Equilateral triangle which is A =
. And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
So, the area of an equilateral triangle =
where, s = side of an equilateral triangle
A =
Cross multiplying the fractions we get;

Now. moving
to the right side of the equation;
Taking square root both sides we get;
Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).

Answer should be $127 that she still needs to save
Morning:
3 pints every 7 minute = 3/7 pints/minute = 0.429 pints/minute
Afternoon:
2 pints every 5 minutes = 2/5 pints/minute = 0.4 pints/minute
Difference:
3/7 - 2/5 = 15/35 - 14/35 = 1/35 pints/minute
0.429 - 0.4 = 0.029 pints/minute
