you buy butter 4.13 a pound one portion of onion requires 1.7 oz of butter how much dose the butter for one portion cost

yuradex [85]

Answer:

<u>The butter for one portion of onion costs $ 0.44</u>

Step-by-step explanation:

Let's recall that 1 pound = 16 ounces, therefore we have:

Cost of one pound of butter = $ 4.13

Cost of sixteen ounces of butter = $ 4.13

How much dose the butter for one portion cost?

We can use Direct Rule of Three for answering this question, as follows:

Ounces Cost

16 4.13

1.7 x

**************************

16x = 4.13 * 1.7

16x = 7.021

x = 7.021/16

x = 0.44 (Rounding to the next cent)

<u>The butter for one portion of onion costs $ 0.44</u>

Carlos graphs the equations y = 0.5x2 + 3 and y = –4x2 + 24x – 35 and generates the graph below. Which conclusion is supported b

never [62]

Answer:

It has no solution

Step-by-step explanation:

Here we have to draw the graph of y = 0.5x^2 + 3 and y = -4x^2 + 24x - 35.

I have attached the graph of these two functions.

Since the graphs of the functions didn't cut each other.

Therefore, answer is "it has no solution."

Hope this will helpful.

Thank you.

10. Create a scenario to explain why 3P3=3!.

Flauer [41]

Step-by-step explanation:

Permutation :The number of ways to choose a sample of r elements from a set of n distinct objects where order does matter and replacements are not allowed.

$nPr = \frac{n!}{(n-r)!}$

Factorial : There are n! ways of arranging n distinct objects into an ordered sequence.

Considering a situation when n = r in a permutation, nPr reduces to n!, a simple factorial of n.

Proof: 3P3 = 3!

n = 3 and r = 3

$3P3 = \frac{3!}{(3-3)!}$

$3P3 = \frac{3!}{(0)!}$

But 0! = 1

3P3 = 3!

What Is k 5(3-2k)=2k+39

Hatshy [7]

Answer:

k = -2.

Step-by-step explanation:

5(3 - 2k) = 2k + 39 Distribute the 5 over the parentheses:

15 - 10k = 2k + 39

15 - 39 = 2k + 10k

12k = -24

k = -2.

Connor rolled a die 6 times. A 2 occurred three times. Why isn't the theoretical probability 3/6 instead of 1/6?

Cerrena [4.2K]

2 occurred 3times

$\\ \sf\longmapsto S=6\times 3=18$

$\\ \sf\longmapsto |S|=18$

Now

$\\ \sf\longmapsto E=No\:of\:times\: 2\:occured$

$\\ \sf\longmapsto |E|=3$

we know

$\boxed{\sf P(E)=\dfrac{|E|}{|S|}}$

$\\ \sf\longmapsto P(E)=\dfrac{3}{18}$

$\\ \sf\longmapsto P(E)=\dfrac{1}{6}$
