Check the picture below.

notice that if we run the "vertical line test", the green vertical line there, touches the graph more than once, and for a function, it has to touch it only once, so no dice.

The jeweler buys gold for 1235.55 per ounce and resells it for 1376.44 per ounce how much profit does the jeweler make from buyi

AnnZ [28]

Profit made by jeweler from buying and reselling ounces of gold is 140.89 per ounce

<u>Solution:</u>

Given that

Price at which jeweler buy gold = 1235.55 per ounce

Price at which jeweler resells gold = 1376.44 per ounce

We need to calculate profit.

Buying price of 1 ounce of gold = 1235.55

Reselling price of 1 ounce of gold = 1376.44

<em>Profit = Reselling price – buying price</em>

So profit on 1 ounce of gold = 1376.44 – 1235.55 = 140.89

Hence profit made by Buying and Selling gold will be 140.89 per ounce

Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute valu

dusya [7]

Inequalities are used to compare unequal expressions.

The actual comparison is: $\mathbf{-3.5 < 5}$ or $\mathbf{5 > -3.5}$

The temperatures are given as:

$\mathbf{Temperature = -3.5F,\ \ 5F,\ \ 1.5F,\ \ -0.5F,\ \ -2F,\ \ 2.5F,\ \ -4F}$

From the above list, we have:

$\mathbf{Day \ 1= -3.5F}$

$\mathbf{Day \ 2= 5F}$

By comparison,

$\mathbf{-3.5 < 5}$ or $\mathbf{5 > -3.5}$

Using absolute values, the inequalities are:

$\mathbf{|-3.5| < |5|}$ or $\mathbf{|5| > |-3.5|}$

Hence, the actual comparison is:

$\mathbf{-3.5 < 5}$ or $\mathbf{5 > -3.5}$

3 out of 5 picks are orange. if 12 picks are orange haw many picks are in all

xxTIMURxx [149]

Answer:

There were 20 picks total

Step-by-step explanation:

We can use a proportion to solve this problem. Put the orange picks on top and the total picks on bottom

3 orange 12 orange

-------------- = ---------------

5 total x total

Using cross products

3x = 5*12

3x= 60

Divide each side by 3

3x/3 = 60/3

x = 20

There were 20 picks total
