<span>It will take 20 minutes. The fridge needs to cool down by 90-50=40degrees. The fridge cools at 2 degrees per minute, i.e. 40/2=20 minutes total.</span>
remember that
![x^{\frac{a}{b}}=\sqrt[b]{x^a}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Csqrt%5Bb%5D%7Bx%5Ea%7D)

and 
so
first one, that one is clearly not equal since 0.25≠4
2nd one, 0.25=1/4, so

answer is 
Mixed number=4 8/10=4 4/5
improper fraction=48/10=24/5

Given
cost to rent the banquet hall for an evening is $185. The cost per plate of food is $3.50. If the tickets to the dinner banquet are $17.50 per person
find out people must attend in order for the school to earn a profit.
To proof
banquet hall cost =$185
cost per plate of food =$3.50
tickets to the dinner banquet =$17.50
let the number of people attend the dinner = x
the equation becomes
17.50x - (3.5x + 185) ≥ 0
now solving the above equation
17.50x - 3.5 x ≥ 185
14x ≥ 185
x ≥ 13.21
x ≥ 14 (approx )
To earn profit 14 people must attend the dinner.
Hence proved
