If 2 over 5 tons of concrete covers 5 over 6 of a wall, how many tons of concrete are required to cover the entire wall?
Dominik [7]

Answer:

A. 12.25 tons

Step-by-step explanation:

We will let x represent the amount required to cover the entire wall.

We can divided 2/5 by 5/6 to solve for x

2/5 divided by 5/6=x

When you divide by a fraction, you can always multiply by the reciprocal (flipped number).

Our new equation is:

2/5·6/5=12/25

The hypotenuse of a right triangle is twice the length of one of its legs. The length of the other leg is three feet. Find the l
Alinara [238K]
Use Pythagorean theorem for side1 = a, side2 =  3, and hypotenuse = 2a
    a² + b² = c²
 a² + (3)² = (2a)
  a² +  9  =  4a²
          9  =  3a²
          3  = a²
         √3 = a

side1 = a = √3 ft
side2 = 3 ft (this was given in the problem)
hypotenuse = 2a = 2√3 ft
