Triangle DEF is on a coordinate plane with its
vertices located at D( – 3,5), E( – 3, - 2), and
F(3,0). What is the area of ADEF in square
units?
Answers
Answer:
[tex]21\ \text{square units}[/tex]
Step-by-step explanation:
The points are [tex]D(-3,5), E(-3,-2)[/tex] and [tex]F(3,0)[/tex].
Area of a triangle is given by
[tex]A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}[/tex]
[tex]\Rightarrow A=\dfrac{-3(-2-0)+-3(0-5)+3(5-(-2))}{2}[/tex]
[tex]\Rightarrow A=21\ \text{square units}[/tex]
The area of the given triangle is [tex]21\ \text{square units}[/tex].

Factoring Explanations Classwork
Directions:
For the following problems, you need to explain what method of factoring you will use and explain all the steps in English words. Do your best to format the math answers. *Some are much easier than others!*
Below are two examples:
Example #1: Factor 18x^2-200y^2 completely.
Answer: For this problem, we will use the difference of squares method.
First, we will factor out the greatest common factor which is 2.
2(9x^2-100y^2 )
Second, we must determine what a and b is.
a=√(〖9x〗^2 )=3x
b=√(〖100y〗^2 )=10y
Third, we put our answer in the form (a+b)(a-b), making sure to include the GCF 2.
Answer: 2(3x+10y)(3x-10y)
Example #2: Factor 2x^2-7x-15 completely.
Answer: For this problem, we will use the X method.
There is no GCF, so we will draw an x and put a*c on top (-30) and b on bottom (-7)
-10 and 3 multiply to get -30 and add to get -7.
Second, we split up the equation to now be this:
2x^2-10x+3x-15
Third, we group it together and factor out the GCF from each group.
(2x^2-10x)+(3x-15)
2x(x-5)+3(x-5)
Fourth and Last, we re-group it together to get our final answer.
Answer: (2x+3)(x-5)

"The difference between the circumference and diameter of a wheel is 18cm. Find the radius of the wheel. Use 3.14 for Pi. Round to the nearest tenth."
Answers
Answer:
[tex]4.2\ \text{cm}[/tex]
Step-by-step explanation:
d = Diameter of wheel
The difference between the circumference and diameter of a wheel is 18 cm.
[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]
The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

6. Find the constant of variation k for the direct variation.

K = -1
K=-1/4
K=4
K=-4
Answers
Given:
The equation for the direct variation is
[tex]4x=-y[/tex]
To find:
The constant of variation k for the direct variation.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is constant of variation or constant of proportionality.
We have,
[tex]4x=-y[/tex]
It can be written as
[tex]-y=4x[/tex]
Multiply both sides by -1.
[tex]y=-4x[/tex] ...(ii)
On comparing (i) and (ii),we get
[tex]k=-4[/tex]
Therefore, the correct option is D.

Answer:

Step-by-step explanation:
Since he’s leaving a 20% tip, we need 20% of 15.
To solve, multiply 20/100 (20%) by 15:
20/100*15 = 300/100 = 3
He will leave a $3 tip.
Answer:
$3
Step-by-step explanation:
To solve this problem, first, one must convert the percent of the tip to decimal form. This can be done by dividing the percent by 100. Then one will multiply this value by the total bill.
20% * 15
= 0.2 * 15

Rope packaged in 80-foot lengths

of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28
Answers
Answer:
it would be 5
Step-by-step explanation:
any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left
80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)
then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed
the whole thing >
80* 5 = 400
400/28 = 33.33
33.33- 28 = 5.33
