Your teacher asks you to find a recipe that includes two ingredients with a ratio of 1/2 cup/ 1/8 cup. a. give an example of two ingredients in a recipe that would meet this requirement. b. if you needed to triple the recipe, would the ratio change? explain. c. what is the unit rate of the ingredients in your recipe? explain and work it out! you!

case a) Give an example of two ingredients in a recipe that would meet this requirement

The example is with flour and sugar

Let

x--------> the number of cups of flour

y-------> the number of cups of sugar

we know that

Part b) If you needed to triple the recipe, would the ratio change?

If the recipe is tripled, the ratio does not change, because both the amount of flour and the amount of sugar will also triple, leaving the ratio constant.

Example

Part c) What is the unit rate of the ingredients in your recipe?

we know that

A unit rate is a rate in which the second rate is 1 unit

in this problem the unit rate is equal to

That means the recipe requires cups of flour per cup of sugar

therefore

the answer Part c) is

The unit rate is equal to

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
