PLEASE HELP

Mathematics
1 answer:
Kaylis [27]3 years ago

Answer:

D. An input is the value that determines another based on the relation or function rule, usually the x-values in a set of ordered pairs on a tale or graph.

Step-by-step explanation:

For any relation  (given ordered pairs), there are x - values and y-values, also called inputs and outputs.  For every input, there is an output.  For example, given the function rule:

y = 2x + 1

If x = 1, y = 3

If x = 2, y = 5

and, so on..

So, the output (y) is determined by the input (x) and is usually the x-values.

A supermarket reduced the price per pound whole chicken by 20%. How many pounds of chicken can now be purchased for the amount o
nignag [31]

Answer:

25 pounds

Step-by-step explanation:

Let us assume that initially, 1 pound of whole chicken costs x.

So, initially 20 pounds of whole chicken costs 20x.

Now, the price is reduced by 20%.

That means that 1 pound of whole chicken now costs  x[1-\frac{20}{100} ]=0.8x

Therefore, with a 0.8x amount of money, we can now purchase 1 pound of the whole chicken.  

Hence, with a 20x amount of money, we can now purchase \frac{20x}{0.8x}=25 pounds of the whole chicken.

Anna007 [38]

Answer:

25.3 lb

Step-by-step explanation:

We can multiply the whole by the percentage to find the part. Since 15.9% is equal to 0.159, the weight of fat is 159*0.159 = 25.281. Round this to the nearest tenth, and we get 25.3 pounds.
