Ashley sells 18.6 kg bags of mixed nuts that contain 60% peanuts. To make her product she adds peanuts to Brand A's mixed nuts w

slavikrds [6]

Answer:

She combines 9.3 kg of each.

Step-by-step explanation:

Let x = amount of brand A in kg

Let y = amount of peanuts in kg

First we deal with the amount of each product she uses.

"Ashley sells 18.6 kg bags of mixed nuts that contain 60% peanuts."

x + y = 18.6

Now we deal with just the amount of peanuts.

"To make her product she adds peanuts to Brand A's mixed nuts which contain 20% peanuts."

Brand A contains 20% peanuts, so x kg of brand A contains 0.2x kg of peanuts.

The peanuts she adds are pure peanuts, so all of y is peanuts.

The result is 18.6 kg of a mixture that is 60% peanuts, so the amount of peanuts in the bags she sells is 0.6 * 18.6 kg.

0.2x + y = 0.6 * 18.6

0.2x + y = 11.16

We have a system of equations:

x + y = 18.6

0.2x + y = 11.16

We have y in both equations, so let's subtract the second equation from the first equation to eliminate y.

0.8x = 7.44

Divide both sides by 0.8

x = 9.3

Plug in 9.3 for x in the first equation of the system and solve for y.

x + y = 18.6

9.3 + y = 18.6

y = 9.3

Answer: She combines 9.3 kg of each.

Please Help! I don't know what the answer is! If you could provide a reason for the answer as well that would help!

NISA [10]

If you go with Blackburn, you have to pay 25 bucks right off, for the web services hosting setup, that's for them to add your account, and allocate resources on their end for you.

After that, for every passing month, you have to pay 5.69 bucks for the service they provide on daily basis.

if you with Randall, they also charge for setup fee, just cheaper, $6 at once, and then for every month is $9.49.

Blackburn for

1 month 5.69(1) + 25

2 months 5.69(2) + 25

3 months 5.69(3) + 25

x months 5.69(x) + 25, or 5.69x + 25

Randall for

1 month 9.49(1) + 6

2 months 9.49(2) + 6

3 months 9.49(3) + 6

x months 9.49(x) + 6, or 9.49x + 6

------------------------------------------------------------------------------------

y = 5.69x + 25
y = 9.49x + 6

Is f(x)=3/4 a function?

Marat540 [252]

Answer:

Yes, f(x) = $\frac{3}{4}$ is a constant function.

Step-by-step explanation:

A function is defined to be a relation from 1 set of numbers to another set of numbers.

The main condition for a relation to be a function is that for every number in the domain there should be a <u>unique image</u>

Here the given function is f(x) = $\frac{3}{4}$

This function is a constant function and gives the value 0.75 for all values of x.

Hence the graph would be a straight line parallel to the x-axis passing through y = 0.75.

Hence the f(x) = 0.75 is a function.
