They need 1 1/2 cups of sugar. How many 1/4 cups should they measure

tekilochka [14]

The correct answer I got was 22 cups. 11/2 ÷ 1/4 is how you set it up. Then, you do KCF which stands for keep, change, flip. So, your new expression is 11/2 × 4/1. You cross reduce 4 & 2 which makes the new expression 11/1 × 2/1. 11 times 2 is 22/1 which still equals 22.

The notation f:S→T denotes that f is a function, also called a map , defined on all of a set S and whose outputs lie in a set T

AnnyKZ [126]

Answer:

There are many. Two examples are

$f(x) = x, \\f(x) = x^3$

Step-by-step explanation:

There are many examples. The simplest is

1 -

$f(x) = x$

It is trivial that

$\text{if \,\,\,\,} f(x) = f(y) \,\,\,\,\,\text{then} \,\,\,\,\, x=y$

2 -

$f(x) = x^3$

That function is injective as well.

$\text{if \,\,\,\,} x^3 = y^3 \,\,\,\,\,\text{then} \,\,\,\,\, x=y$

An example of a function that is NOT injective is

$f(x) = x^2$

Notice that

$f(-2) = (-2)^2 = 2^2 = 4$

A farmer sells almonds according to the chart below. The more pounds of almonds that are sold, lower cost the cost per pound is

Naddik [55]

Answer:

horizontal line with a open circle at (20,10) and an closed circle at (30,10)

$ 207.50

Step-by-step explanation:

20.75 is between 20 and 30

From the given table , we can see that

for more than 20, up to 30 pounds, the cost per pound is $10

This means, the pounds greater than 20 and less than 30 cost per pound is $10

More than 20 means pounds not equal to 20. its close to 20

So there is a open circle at 20

Cost per pound remains the same from 20 to 30

So horizontal line with a open circle at (20,10) and an closed circle at (30,10)

Total cost of 20.75 pounds of almonds = 20.75 * 10 = 207.50
