A certain bread recipe asks you to combine flour and yeast with 3 cups of warm 115 *F water. If the water is hotter or colder than that, then the bread won't rise. All you have available are hot tap water that is 140 F and refrigerated water that is 40 °F. How much hot tap water and refrigerated water should you mix together to get 3 cups of 115 F water? cups of hot tap water. cups of refrigerated water. Round your answers to 2 decimal places.

2.25 cups of hot tap water and 0.75 cup of refrigerated water.

Step-by-step explanation:

Let x= Number of cups of hot tap water that is 140°F.

and y = Number of cups of refrigerated water that is 40°F.

To find : How much each of them we should mix to get 3 cups of 115° F water.

According to the question , we have

Substitute value of y from (i) in (ii) , we get

Put this in (i) ,  y= 3-2.25=0.75

Hence, we require 2.25 cups of hot tap water and 0.75 cup of refrigerated water.

answer

106 emergencies

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
