Answer:
9.103
10. 77
11.60
12. 6.4
13. 20
14. 36
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
180 - (47 + 30) = 103
DEG = 180 - 103 = 77 angles on a straight line equals 180
An equilateral triangle has all 3 sides equal
if the sum of angles in a triangle is 180 degrees, each angle measures 180 / 3 = 60
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
5² + 4² = 41
squareroot of 41 = 6.4
b : √(25² - 15²) = 20
√(60² - 48²) = 36
well, the remainder theorem says that if the polynomial f(x) has a factor of (x-a), then if we just plug in the "a" in f(x) it'll gives a remainder, assuming (x-a) is indeed a factor, then that remainder must be 0, so if f(a) = 0 then indeed (x-a) is a factor of f(x). After all that mumble jumble, let's proceed, we have (x+1), that means [ x - (-1) ], so if we plug in -1 in f(x), we should get 0, or f(-1) = 0, let's see if that's true.
Answer:
<u><em>C, </em></u> Expression B and Expression D
Step-by-step explanation:
<h2><u><em>
Step 1 : Analyzing the question:</em></u></h2>
The regular price of an item at a store is p dollars. The items is
on sale for 10% off the regular price. Some of the expressions
below represent the sale price, in dollars, of the item.
It says " <em>item on sale for 10% off </em>". That means or .
<h2><u><em>
Step 2 : Looking at the next portion of the question:</em></u></h2>
Expression A: 0.1p
Expression B: 0.9p
Expression C: 1 - 0.1p
Expression D: p - 0.1p
Expression E: p - 0.0p
<u>Expression A</u> doesn't make any sense. It only shows the how
much you save
<h3>
<em><u>Expression B:</u></em> This is one of the answer. </h3><h3 /><h3>
</h3><h3 />
<u>Expression C: </u> You can't subtract from
<h3>
<em><u>Expression D: </u></em> D makes sense.
</h3><h3 />
<u>Expression E: </u> This is the same thing as
<h2><u><em>
Step 3: The answers:</em></u></h2>
<u><em>The answer is C .</em></u>
