This is the concept of algebra. Given that Holly has 30 pencils, the total number of pencils that Holly remained with after she gave her friends 6 pencils are:
Total=30-6=24 pencils
The fraction of pencils that need to be sharpened is 3/8
The number of pencils represented by this fraction will be:
(fraction of un-sharpened pencils)×(total number of remaining pencils)
3/8×24
=9 pencils
therefore we conclude that 9 pencils are not sharpened.
Answer:
, 
Step-by-step explanation:
Part a) Find the sin(A)
we know that
In the right triangle ABC
----> the sine of angle (A) is the opposite side angle (A) divided by the hypotenuse
substitute the values
Part b) Find the cos(A)
we know that
In the right triangle ABC
----> the cosine of angle (A) is the adjacent side angle (A) divided by the hypotenuse
substitute the values
<u><em>The surface Area is multiplied by 1/4</em></u>
<u><em>I apologize if am wrong</em></u>
<u><em>Good luck!</em></u>
Answer:
y = - 1/4 x
Step-by-step explanation:
Look for the slope of this graph.
Take for an example of a point. Let's take (-4,1) and (0,0)
Now let's see how many downs and rights needed to go from (-4,1) to the origin (0,0).
As you can see, it goes 1 down and 4 rights.
So now you know the slope of the line which mean you can choose one of the choices now.
1 down, means negative one (-1), will be a numerator of the slope fraction and 4 right, meaning positive four (4), will be a denominator of the slope fraction.
<em>Note: This method is only available when you see two easy points to determine. In most cases you have to do the math using the slope formula.</em>
