Answer:
Maria
Step-by-step explanation:
Find the ratio of powdered mix to water for each drink.
For Maria:
(2/3 cup) / (2 gallon)
= 1/3 cup per gallon
For Franco:
(1 1/4 cup) / (5 gallon)
= (5/4 cup) / (5 gallon)
= 1/4 cup per gallon
Since 1/3 is bigger than 1/4, Maria's sports drink is stronger.
Answer:
Step-by-step explanation:
Recall that, in this case, the subset of X for which R is defined is called the domain of R. The mistake occurs when we assume that the domain R is the whole set X, but it could happen that R is not defined for some elements of X.
Recall the following example:
X = {2,4,6}.
We can define R as follows {(2,2), (4,4), (2,4), (4,2)}. We can easily check that this is a transitive and symmetric relation, but since we don't have the element (6,6) it fails to be reflexive.
Answer:
a)
b) l=19.2 units
Step-by-step explanation:
a)Let F represent the force and l represents the length of the wrench handle.
Then inverse variation relation is:
When we introduce the variation constant, we get:
From the question when F=96, l=12
The equation is
b) If a person can only exert 60 pounds of force on a wrench,then
Hence the length of the wrench must be 19.2 units
The answer is 7,500.
Hope that helped!!!
