Answer:
3/10
Step-by-step explanation:
To find how much remains, you need to find 1/2 of 3/5 which is 1/2 * 3/5. To multiply the two fractions, multiply the two numerators and multiply the two denominators to get 3/10. Thus, 3/10 of the candy bar remains.
Hope this helps :)

<h3>Answer</h3>
a = 36
b = √3/5
════════════════════
<h3>Known </h3>
Adjuscent = 12√3
════════════════════
<h3>Question</h3>
Opposite = ?
Hypotenuse = ?
════════════════════
<h3>Way to do</h3>
• finding a - opposite
#use tan formula
tan(∅) = opposite / adjuscent
tan(60) = opposite / 12√3
opposite = tan(60) × 12√3
opposite = 36
•finding b - hypotenuse
#use cos formula
cos(∅) = adjuscent / hypotenuse
cos(60) = 12√3 / hypotenuse
hypotenuse = 12√3 : cos(60)
hypotenuse = √3/5

Answer:
<u>135.73 ounces</u> of a silver alloy that costs $5.50 per ounce should be mixed.
Step-by-step explanation:
Given:
A silver alloy that costs $5.50 per ounce should be mixed with one that costs $7.00 per ounce to make a new 30 ounce alloy that costs $6.40 per ounce.
Now, to find the ounces of silver alloy.
Let the silver costs $5.50 per ounce be 
And the silver costs $7.00 per ounce be 
So, the total ounce make a new alloy:
....(1)
Now, the total costs of silver alloy:

Putting the value of
from equation (1) in the place of
:



<em>Subtracting both sides by 210 we get:</em>

<em>Dividing both sides by -1.5 we get:</em>

Therefore, 135.73 ounces of a silver alloy that costs $5.50 per ounce should be mixed.
The equation for slope is <u>y² - y
</u> x² - x
So it would be: <u>8 - (-20)</u> or <u>8 + 20
</u> 5 - 3 5 - 3
<u>28</u>
2
Then, you have to reduce it, divide both by two.
<u>14</u>
1
Since it is over 1, then it is just the numerator.
Your final is:
<em>Slope = 14</em>
