identify the correct reason for the second node
A. Reflection
B. Definition of midpoint
C. Definition of congruent segments
I think your teacher meant to say Reflexive property instead of reflection. The reflexive property is the idea that any segment is the same length as itself. It seems like a trivial idea, but it's useful to be able to pull triangles apart like in this problem here.
Note: when naming a segment, the order of the endpoints listed doesn't matter. So that's why EU is the same as UE.

Molly and Norachai are selling pies for a school fundraiser. Customers can buy blueberry pies and pumpkin pies. Molly sold 5 blueberry pies and 12 pumpkin pies for a total of $143. Norachai sold 10 blueberry pies and 8 pumpkin pies for a total of $142. Find the cost each of one blueberry pie and one pumpkin pie.
Answer:
Blueberry costs 9 dollars
Pumpkin costs 7 dollars
Step-by-step explanation:
Let "b" represent the price of a blueberry pie
Let "p" represent the price of a pumpkin pie
Step 1: Set equation
5b + 12p = 143 ----- 1
10b + 8p = 142 ----- 2
Step 2: Isolate 1 for "b"
5b = 143 - 12p
[tex]b = \frac{143}{5}-\frac{12}{5}p[/tex] ------- 3
Step 3: Substitute 3 into 2
[tex]10(\frac{143}{5}-\frac{12}{5} p )+8p=142\\286 - 24p + 8p = 142\\-24p + 8p = 142 - 286\\-16p = -144\\p = -\frac{144}{-16}\\ p = 9[/tex]
Step 4: Subsitute p = 9 into 1 for b
[tex]5p + 12(9) = 143\\5p + 108 = 143\\5p = 143 - 108\\5p = 35\\\frac{5p}{5}=\frac{35}{5}\\p = 7[/tex]
Therefore a pumpkin pie costs 7 dollars while a blueberry pie costs 9 dollars
Giles is searching for a sock and he discovers he has 10 socks for every 5 pair of shoes.If he has 20 socks, how many pairs of shoes does he have
Answer:
10
Step-by-step explanation:
Answer:
10 shoes
Step-by-step explanation:
Step 1: State what is known
Giles has 10 socks for every 5 pairs of shoes
He has 20 socks
Step 2: Set up the ratio
Let 'x' represent how much shoes Giles has
10 socks : 5 shoes
20 socks : x shoes
Step 3: Convert ratio into fraction
[tex]\frac{Socks}{Shoes}[/tex]
10 socks : 5 shoes = [tex]\frac{10}{5}[/tex]
20 socks : x shoes = [tex]\frac{20}{x}[/tex]
Step 4: Set ratio equal to each other and solve
[tex]\frac{10}{5}=\frac{20}{x}\\ 10x = 100\\\frac{10x}{10}=\frac{100}{10}\\x = 10[/tex]
Therefore Giles has 10 shoes when he has 20 socks

Jemima bought 150 oranges at ¢12 and sold them at 6 for 30gp find the profit or loss
Answer:
The loss is ¢ 4.50Step-by-step explanation:
To calculate either the profit or loss we must first find the cost price and the selling price
For the cost price
She bought 150 oranges at ¢12
Cost price = ¢ 12.00
For the selling price
She sold 6 at 30 Gp that's ¢ 0.30
If she sold 6 at ¢ 0.30
Then 150 will be 150× 0.3/ 6
Selling price = ¢ 7.50
Since the cost price is higher than the selling price she made a loss
Loss = Cost price - Selling price
Loss = ¢ 12 - ¢ 7.50
Loss = ¢ 4.50Hope this helps you

The function h(t) --4.922 +17.69+575 is used to model the height of an object being tossed from a tall building, where h(t) is
the height in meters and t is the time in seconds. What are the domain and range? Round to the nearest hundredth.
domain: [0, 12.76]
range: (1.80, 590.90)
domain: [1.80,12.76]
range: [1.80, 590.90)
domain: [1.80,12.76]
range: [0, 590.90]
domain: [0, 12.76]
range: [0,590.90]
Answer:
Domain: [0, 12.75]
Range: [0, 590.9]
Step-by-step explanation:
Your function is missing variables.
I think you mean
h(t) = -4.922t^2 + 17.69t + 575
as the function.
We can find the time the object hits the ground. At that time, h(t) = 0, so we set the equation equal to zero and solve for t.
-4.922t^2 + 17.69t + 575 = 0
[tex] t = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] t = \dfrac{-17.69 \pm \sqrt{(-17.69)^2 - 4(-4.922)(575)}}{2(-4.922)} [/tex]
[tex] t = \dfrac{-17.69 \pm \sqrt{11633.54}}{-9.844} [/tex]
t = -9.16 s or t = 12.75 s
According to the parabola that is the path of the falling object, the object is at zero height at t = -9.16 s and t = 12.75 s. Since the object starts moving at time t = 0, the domain has to be limited to t = 0 till t = 12.75 s.
Domain: [0, 12.75]
The range is the height of the object. Maximum height occurs at the time that is the midpoint of the two times the parabola shows h(t) = 0.
tmax = (-9.16 + 12.75)/2 = 1.797
Now we use the time of maximum height to find the maximum height.
h(t) = -4.922t^2 + 17.69t + 575
h(tmax) = -4.922(1.797)^2 + 17.69(1.797) + 575
h(tmax) = 590.9
The maximum height is 590.9 m.
Range: [0, 590.9]
Consider N{A} = 4 and N{B} = 5. (a) What is the smallest number possible for N{A ∩ B}? (b) What is the largest number possible for N{A ∪ B}?
Answer:
(a) N{A∩B} = 0
(b) N{A∪B} = 9
Step-by-step explanation:
Union of two sets: This can be defined as the sum of all the elements of the two sets without writing one element twice. it is denoted by the symbol ∪
Intersection of two sets; This is the set of elements that appears in both sets. It is denoted by the symbol ∩
From the question above,
assuming there is no repetition element in both set,
(a) The smallest number possible for N{A∩B} = 0
(b) The largest number possible for N{A∪B} = 4+5 = 9.
You invest 5000 dollars in an account at 1.6% interest is compounded annually (once a year) a) write an equation that shows the amount of money you have after x years b) How much money would you have after 15 years
Answer:
a. P= 5000( 1.016)^x
b. $ 6344.18
Step-by-step explanation:
The equation for finding the compound interest annually is
P = P_1 ( 1 +r)^t
Here
P = the amount after the interest has been added or the new balance
P_1= the principal amount
r= rate at which interest is charged
t= time in years
So we have
P = the new balance
P_1= the principal amount= $ 5000
r= rate at which interest is charged= 1.6 %
t= time in years= x
Putting the values in the above equation
P = P_1 ( 1 +r)^t
P = 5000 ( 1+ 1.6/100) ^x
P= 5000( 1.016)^x
b) When t= 15
Again
Putting the values in the above equation
P = P_1 ( 1 +r)^t
P = 5000 ( 1+ 1.6/100)^15
P = 5000( 1.26883637) = 6344.18185= $ 6344.18

Answer:
See answer is Explanation
Step-by-step explanation:
4 divided by 25 is 0.16
6 divided by 25 is 0.24
6 x 4 = 24
4 x 25 = 100
6 x 25 = 150
14 + 19 = 313
25 + 13 = 328
7 + 18 = 235
10 + 40 = ?
Answer:
540
Step-by-step explanation:
since that the first is 14+19 and they are just adding 4+9 which is 13 so, the last is just a 3, and 1+1 is 2, plus the 1 that we have from the 13, then, you just add 1 on the Middle.
With 25+13 also you add normally, just add a 2 on the middle. And With the 3rd one add a 3 on the middle. So, with the last one, you add a 4 too.

Answer:
351.48cm²
Step-by-step explanation:
Heron’s Formula
Find half the perimeter (30+30+26)/2=43
It’s the square root of each side subtracted from 43, multiplied together, times 43.
√(43-30)*(43-30)*(43-26)*43=√13*13*17*43=√=123539=351.481cm²
Area of triangle is, 351. 39 cm²
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
All the sides of triangles are,
⇒ 30 cm, 30 cm, and 26 cm
We know that;
⇒ Area of triangle = √ s (s - a) (s - b) (s - c)
Where, 's' is the semi perimeter of the triangle, and a, b and c are three sides of triangle.
Here, Sides are,
⇒ a = 30
⇒ b = 30
⇒ c = 26
Hence, We get;
⇒ s = (a + b + c) / 2
⇒ s = (30 + 30 + 26) / 2
⇒ s = 86 / 2
⇒ s = 43 cm
So, The area of triangle is,
⇒ Area of triangle = √ s (s - a) (s - b) (s - c)
⇒ Area of triangle = √ 43 (43 - 30) (43 - 30) (43 - 26)
⇒ Area of triangle = √ 43 × 13 × 13 × 17
⇒ Area of triangle = 13 √ 731
⇒ Area of triangle = 13 × 27.03
⇒ Area of triangle = 351. 39 cm²

Please find attached the required inverse of a function chart
Step-by-step explanation:
The inverse of a function is found by reversing the operations of the function
The inverse of the function f(x) = 2·x - 4 is found as follows;
x = 2·x - 4
x + 4 = 2·x
x = (x + 4)/2 = x/2 + 2
Therefore, the inverse of the function f(x) = 2·x - 4 is f(x) = x/2 + 2
The inverse function is plotted by generating data points as follows;

For a 180° rotation about the origin, write the coordinates of each point in the table.
Answer:
Hey, you don't include any points, but I can give you the rule for an 180 degree rotation.
You just need to write the same points, but negative. So going from (x,y) to
(-x,-y).
As an example let's say you wanted to rotate (3,-4) 180 degrees about the origin. The the point after the rotation would be (-3,4).

solve inequality 5x+1<=3x-17
Answer:
-9 >= x
Step-by-step explanation:
5x + 1 <= 3x - 17
add 17 to both sides- that will cancel the one on the right side. And on left side it would add to 18
5x + 18 <= 3x
then subtract 5x from both sides- that will cancel the one on left side. And on the right side ur left with negative 2x
18 <= -2x
divide both sides by negative 2... since dividing by -2 u have to slip the inequality sign.
-9 => x

Please solve, 1-8n-8= -7n-6n-12?
Answer:
n = -1
Step-by-step explanation:
1 - 8n - 8 = -7n - 6n - 12
Simplify
-8n - 7 = -13n - 12
Add 7 to both sides
-8n = -13n - 5
Add 13n to both sides
5n = -5
Divide both sides by 5
n = -1
Answer:
n = 1
Step-by-step explanation:
1 - 8n - 8 = -7n - 6n - 12
-8n + 7n + 6n = -12 + 8 - 1
5n = -5
n = -5/5
n = -1

1 - 8*-1 - 8 = -7*-1 - 6*-1 - 12
1 + 8 - 8 = 7 + 6 - 12 = 1
Ali is making pottery. He uses 38 of a 2-pound bag of clay to make a set of bowls. Each set has 4 bowls. Drag one expression next to each question. The correct expression for each row is a way to answer that question.
Answer:
[tex]\frac{3}{8}[/tex]
[tex]2\times \frac{3}{8} = \frac{3}{4}[/tex]
Step-by-step explanation:
According to the given scenario given that
if Ali uses [tex]\frac{3}{8}[/tex] of 2 pounds of clay for a game of 4 bowls
[tex]\frac{3}{8} (2) = \frac{6}{8} = \frac{3}{4}[/tex]
here Ali will use the number of pounds of clay to create a game
[tex]2\times \frac{3}{8} = \frac{3}{4}[/tex]
Now, we need to compute the number of pounds of clay that should be used in every bowl, we need to divide the prior outcome by 4 which is
[tex]\frac{2\times \frac{3}{8}}{4}[/tex]
