Given triangle XP’s is congruent to triangle dnf, find the values of x and y.
Answers
Since they only give you two sides of ΔXPS, then you know that:
XP (4y-3)= DN (57)
XS (17x+3) = DF (54)
4y - 3 = 57
4y = 60
y = 15
17x + 3 = 54
17x = 51
x = 3
So the answers are:
x = 3
y = 15
x = 3
y = 15
Let's establish the proportion below to find the value of x and y
XP / DN = XS / DF = PS / NF
Since only 2 sides of XPS is given, then
4y - 3 = 5717x + 3 = 54Therefore,
4y = 60
y = 60 / 4
y = 15
17x = 57
x = 57 / 17
x = 3

The Witches coven are making a potion and Ethel, Glinda, Locasta and Circe each add a different ingredient. When the potion is finished, there is 1/4 of the bat blood left, 1/3 of the knotgrass, 1/2 of the moonstone and 5/8 of the unicorn hair. Ethel used the most. Glinda used the least. Locasta used more than Circe. Who used the moonstone?
Answers
The moonstone was used by [tex]\fbox{\begin\\\ \bf Circe\\\end{minispace}}[/tex].
Further explanation:
It is given that a potion is prepared by a group of witches. The members in the group are Ethel, Glinda, Locasata and Circe.
The ingredients used in the preparation of the potion are bat blood, knotgrass, moonstone and unicorn hair.
Each member of the group add a different ingredient which means that no two member of the group add the same ingredient.
As the preparation of the potion is finished it is observed that the [tex]\dfrac{1}{4}th[/tex] of the bat blood is left, [tex]\dfrac{1}{3}rd[/tex] of the knotgrass is left, [tex]\dfrac{1}{2}nd[/tex] of the moonstone is left and [tex]\dfrac{5}{8}th[/tex] of the unicorn hair is left.
From the above statement it is concluded that [tex]25\%[/tex] of the bat blood is left, [tex]33.33\%[/tex] of the knotgrass is left, [tex]50\%[/tex]of the moonstone is left and [tex]62.5\%[/tex] of unicorn hair is left.
Therefore, the percentage of ingredients used in the preparation of the potion are as follows:
Bat blood: [tex]75\%[/tex] is used
Knotgrass: [tex]66.67\%[/tex] is used
Moonstone: [tex]50\%[/tex] is used
Unicorn hair: [tex]37.5\%[/tex] is used
As per the question Ethel used the most so, the ingredient bat blood was used by Ethel.
As per the question Glinda used the least so, the ingredient unicorn hair was used by Glinda.
It is given that Locasta used more than Circe so, the ingredient knotgrass was used by Locasta and moonstone was used by Circe.
Therefore, the ingredient moonstone was used by [tex]\fbos{\begin\\\ \bf Circe\\\end{minispace}}[/tex].

I have time until Friday, December 1. Please help me!! I’m really confuse with problem. Question is “Find the measure of the angle marked «X» ” Thank u in advance!!!!!
Answers
∠D + 60 + 50 = 180
∠D + 110 = 180
∠D + 110 (-110) = 180 (-110)
∠D = 70
Due to vertical angles (theorem?), the ∠FDE is also 70°
to find ∠DFE, find ∠BDF
∠BDF = 180 - 70 (this 70 is from ∠D)
∠BDF = 110
∠BFD = 180 - 110 - 20
∠BFD = 50
∠D = 70
ΔFDE = x + 70 + ∠F
ΔAD'E = 180
∠D' = 70
∠DFC = 110
angle bisector states that it makes two equal angles
110/2 = 55
∠DFE= 55
180 - 70 - 55 =
180 - 125 =
55
x = 55°

Answers
It is basically a trick question. Firstly we have to ficus on the given formula to get to the answer for this question.
2l + 2w = 16
2(l + w) = 16
l + w = 8
l = 8 - w
Mow w cannot be less than 1. So the length of the rectangle cannot be more than 7. So we can conclude that 7 inches is the correct option or the first option is the correct option among the given options.

Taylor made 5 1⁄4 cups of iced tea. How many 10 ounce glasses can he fill to the brim with iced tea?
Answers
4
Explanation:
Word problems like this are always a bit tricky to get to the bottom to.
But to put it simply, this question is asking how many times can 10 oz be taken out of 5 1/4 cups. This is also shown as:
5 1/4 cups ÷ 10 ounces
First, make both numbers the same units. Since ounces are smaller, convert 5 1/4 cups into ounces.
5 1/4 cups
5 cups = 40 ounces
1/4 cup = 2 ounces
40 + 2 = 42 ounces.
so now do this:
42 ÷ 10 = 4.2
So Taylor can fill 4 full glasses with iced tea.

Which of these is the statement of the zero product rule?
A. If a • b = 0, then either a = 0 or b = 0, but not both.
B. If a • b = 0, then a = 0 and b = 0.
C. If a • b = 0, then a = 0.
D. If a • b = 0, then either a = 0 or b = 0, or both.
Answers
Answer: Hello mate!
If you have any real number A; you always have that:
A*0 = 0
this means that the product between a number A and zero, is equal to zero, and this is for every number. (note that A can be equal to 0, and 0*0 = 0)
Then if a*b = 0, you know that, at least one of the numbers is equal to zero, and there is possible that both numbers are equal to zero.
And with this information, you can see that the right answer is D.
"if If a • b = 0, then either a = 0 or b = 0, or both."
because:
0*b = 0
a*0 = 0
0*0 = 0
Final answer:
The zero product rule states that if the product of two multiplicands equals zero, then at least one of the multiplicands must be zero, which is correctly represented by option D.
Explanation:
The correct statement of the zero product rule is: If a • b = 0, then either a = 0 or b = 0, or both. This is accurately represented by option D. The zero product rule is a foundational concept in algebra that asserts when the product of two or more numbers or variables equals zero, at least one of the multiplicands must be zero. It's crucial for solving equations where a product is set equal to zero, as it allows for each factor to be set equal to zero and solved individually. This rule is pivotal in finding solutions to polynomial equations, among others. For example, in the equation (x + 2)(x - 3) = 0, applying the zero product rule we set each factor equal to zero: x + 2 = 0 or x - 3 = 0, leading to the solutions x = -2 or x = 3, respectively.

Since, in inequality,
'>' = greater than,
'<' = less than,
'≥' = greater than equal to,
'≤' = less than equal to,
Now, 1.67 × 10 = 16.7
⇒ 16.7 is 10 times of 1.67,
That is,
1.67 is less than 16.7

Reason 2: Same Side Interior Angle Theorem
Reason 3: Definition of Supplementary
Reason 5: Definition of Congruence
Reason 7: Definition of Supplementary
------------------------------------
Explanation:
Reason 2: The "Same Side Interior Angle Theorem" is the idea that if we know two lines are parallel, then the interior angles on the same side of the transversal line will be supplementary (add to 180 degrees). In other words, the two angles can be combined to form a straight angle
Reason 3: If we're told two angles are supplementary, then by definition it means they add to 180 degrees.
Reason 5: If two angles are congruent, then they have the same measure (eg: both are 60 degrees)
Reason 7: This is the reverse of reason 3, more or less. If we know two angles add to 180 degrees then we can say they are supplementary. When it comes to definitions we can reverse it (i.e, if P, then Q reverses to if Q then P)

The detailed answer explains how to divide a polynomial by another using long division method.
Explanation:
To divide -2x³-5x²+4x+2 by x+2, we will perform polynomial long division:
-2x³-5x²+4x+2 / x+2
Start by dividing the leading terms: -2x³ / x = -2x². Multiply x+2 by -2x² to get -2x³-4x². Subtract this from -2x³-5x² to get x². Bring down the 4x next. Continue the process and you will get a quotient of -2x²+x-2 with a remainder of 6.
