In this item, we are to determine the equation that would allow us to express the given. If x is the number of barrels of water and y is weight, the points are:
(10, 98.4) and (20, 181.8)

To determine the equation of the line, we use,

    y - y₁ = ((y₂ - y₁)/(x₂ - x₁))(x - x₁)

Substituting,
    
     y - 98.4 = ((181.8 - 98.4)/ (20 - 10))(x - 10)

Simplifying,

     y = 8.27x + 88.4

William, his brother, and their 3 sisters won of the science fair prize money. What fraction of the prize
frozen [14]

Answer:

1/5 of the prize money each

Step-by-step explanation:

If there are 5 siblings and the money is being distributed equally between the five of them, each sibling would get 1/5 of the prize money.

To understand this lets think of the prize as 1 whole. If we divided 1 whole into 5 equal parts, each part would be 1/5, or you can think of it as "1 out of 5".

Which expression is equivalent to ^4 sqrt 144a^12 b^3
Alex_Xolod [135]
The expression equivalent to <span> ^4 sqrt 144a^12 b^3 will be found by simplifying our expression as follows:
</span><span> ^4 sqrt 144a^12 b^3
=(144a^12b^3)^(1/4)
=(12^2a^12b^3)^(1/4)
=12^(1/4*2)a^(12*1/4)b^(3*1/4)
=12^(1/2)a^3b^(3/4)

Answer: </span>12^(1/2)a^3b^(3/4)
