how many distinct lines represent altitudes medians interior angle bisecrots of a isosceles triangle but not equilateral
Answers
The altitudes, the medians, and the angle-bisectors are distinct for the congruent sides but coincident for the base. Hence, 7 lines.
Now, According to the question:
Altitude. A line segment joining a vertex of a triangle with the mid-point of the opposite side. An altitude is a perpendicular line segment drawn from a vertex of a triangle to the opposite side. It divides the opposite sides into two equal parts.
A Median of a triangle is a straight line segment which is drawn from the vertex of a triangle to the middle point of the opposite side. It splits the opposite side of the triangle into two equal line segments. That means we know that it's a median if we have got those equal line segments.

8. At a fund raising event, a booth was set up to sell handmade cards and photo
frames. On the first day, 3 cards and 9 photo frames were sold for a total of $75.
The next day, 8 cards and 5 photo frames were sold for a total of $67.
Find the selling price of a card and the selling price of a photo frame.
Answers
We can start solving this problem by using a system of equations. Let x be the selling price of a card and y be the selling price of a photo frame.
From the information given, we know that on the first day:
3x + 9y = 75 (1)
And on the second day:
8x + 5y = 67 (2)
Now we have two equations with two variables. To find the value of x and y, we can use either substitution or elimination method.
One possible way to solve for x and y is to use substitution method:
Solve equation (1) for x in terms of y:
x = (75 - 9y) / 3
Substitute this expression into equation (2) to eliminate x:
8((75 - 9y) / 3) + 5y = 67
Solving this equation for y:
y = 3
Now we can substitute this value of y back into equation (1) or (2) to find the value of x:
3x + 9(3) = 75
3x = 48
x = 16
So the selling price of a card is $16 and the selling price of a photo frame is $3.
Answer:
Photo frame = $7
Card = $4
Step-by-step explanation:
Define the variables:
Let c = the selling price of a handmade card (in dollars).Let p = the selling price of a handmade photo frame (in dollars).Given information:
On the first day, 3 cards and 9 photo frames were sold for a total of $75.On the next day, 8 cards and 5 photo frames were sold for a total of $67.Create a system of linear equations using the given information and defined variables:
[tex]\begin{cases}3c + 9p = 75\\ 8c + 5p = 67\end{cases}[/tex]
Rearrange the first equation to isolate c:
[tex]\implies 3c+9p=75[/tex]
[tex]\implies 3(c+3p)=75[/tex]
[tex]\implies \dfrac{3(c+3p)}{3}=\dfrac{75}{3}[/tex]
[tex]\implies c+3p=25[/tex]
[tex]\implies c+3p-3p=25-3p[/tex]
[tex]\implies c=25-3p[/tex]
Substitute the expression for c into the second equation and solve for p:
[tex]\implies 8c+5p=67[/tex]
[tex]\implies 8(25-3p)+5p=67[/tex]
[tex]\implies 200-24p+5p=67[/tex]
[tex]\implies 200-19p=67[/tex]
[tex]\implies 200-19p-200=67-200[/tex]
[tex]\implies -19p=-133[/tex]
[tex]\implies \dfrac{-19p}{-19}=\dfrac{-133}{-19}[/tex]
[tex]\implies p=7[/tex]
Therefore, the selling price of a handmade photo frame was $7.
Substitute the found value of p into the expression for c and solve for c:
[tex]\implies c=25-3p[/tex]
[tex]\implies c=25-3(7)[/tex]
[tex]\implies c=25-21[/tex]
[tex]\implies c=4[/tex]
Therefore, the selling price of a handmade card was $4.

The coordinate points for cups of flour, x and loaves of bread y is given in the table.
The slope-intercept form of an equation is - y = mx + b
To find the slope m use the formula -
(y2 - y1)/(x2 - x1)
Substituting the values in the equation -
(3 - 2)/(9 - 6)
1/3
So, the slope point is obtained as m = 1/3.
The equation becomes - y =1/3 x + b
To find the value of b substitute the values of x and y in the equation -
2 = 1/3(6) + b
2 = 2 + b
b = 2 - 2
b = 0
So, the value for b is 0.
Now, the equation becomes -
y = 1/3x + 0
y = 1/3x
The graph is plotted for the equation.
Therefore, the equation is y = 1/3x.

of five letters (a, b, c, d, and e), three letters are to be selected at random. how many possible selections are there?
Answers
Three letters will be selected from five letters. The number of possible selections is 10.
A combination is a method of picking elements from a collection where the order of selection is irrelevant. Assume we have three numbers P, Q, and R. The number of ways we can choose two numbers from each set is determined by combination.
Suppose we want to pick k elements from a set of n elements, then the number ways it can be chosen is:
C(n,k) = n! / k! (n-k)!
Where n! is n factorial.
In this case, there are 5 letters and we want to select three letters. Hence, k = 3, and n = 5.
C(5,3) = 5! / 3! (5-3)!
C(5,3) = 5! / (3! 2!) = 10
Thus, there are 10 possible selections.

a represents pounds of apples and b represents pounds of bananas. guillermo and cara are finding and interpreting the solution. is either correct? explain your reasoning.
Answers
Both Guillermo's and Cara's solutions are incorrect due to the incorrect substitution of values of a variable to find the dependent one.
Guillermo's solution is incorrect because he did not substitute the value of 'b' from the first equation into the second equation. Instead, he directly added 0.49b to both sides and solved for a, which gives an incorrect result.
Cara's solution is also incorrect because she did not substitute the value of 'a' from the first equation into the second equation. Instead, she used the equation a + b = 7 to solve for the value of b, which gave her an incorrect result.
We can find the correct solution as follows -
The system of equations is,
⇒ a + b = 7 .. (i)
And 1.29a + 0.49b = 6.63 .. (ii)
Now, we will solve the system of equations as follows -
⇒ a + b = 7
⇒ a = 7 - b .. (i)
And, ⇒ 1.29a + 0.49b = 6.63 .. (ii)
Substitute the value of a from (i) in (ii), we get;
⇒ 1.29a + 0.49b = 6.63
⇒ 1.29(7 - b) + 0.49b = 6.63
⇒ 9.03 - 1.29b + 0.49b = 6.63
⇒ - 0.8b = 6.63 - 9.03
⇒ - 0.8b = - 2.4
⇒ 0.8b = 2.4
⇒ b = 2.4 / 0.8
⇒ b = 3
And, From (i);
⇒ a = 7 - b .. (i)
⇒ a = 7 - 3
⇒ a = 4

An autonomous first order ordinary differential equation is any equation of the form: dy/dt = f(y).
1. Stable: The equilibrium solution y(t) = c is stable if all solutions with initial conditions y0 ‘near’
y = c approach c as t → ∞.
2. Unstable: The equilibrium solution y(t) = c is unstable if all solutions with initial conditions y0 ‘near’ y = c do NOT approach c as t → ∞.
3. Semi-stable: The equilibrium solution y(t) = c is semistable if initial conditions y0 on one side of c lead to solutions y(t) that approach c as t → ∞, while initial conditions y0 on the other side of c do NOT approach c.
Find the equilibrium points for the differential equation (1) and determine whether each is asymptotically stable, semistable, or unstable.

Since the sum of the lengths of pieces E and F is 5 feet, which is less than the length of piece D, it is not possible to make a triangular garden using these pieces.
Part C: Wendell can make a rectangular garden with the pieces of wood he has by using pieces A and C or pieces B and D. He cannot use pieces E and F because they are not long enough to make up one of the sides of a rectangle.
Part D: Wendell can not create two triangular gardens using all six pieces of wood as the sum of the lengths of the two shorter sides of a triangle must be greater than the length of the longest side, and he only have 3 pieces with length greater than 3 feet which is required to create one triangle.
Wendell can create two rectangular gardens using all six pieces of wood by using pieces A and C, and pieces B and D.

Answers
ΔABC and ΔDEF are not similar because corresponding angles are not equal.
Now, According to the question:
In triangle ABC :
The measure of angle A is 35º and
The measure of angle B is 20°.
In triangle DEF:
The measure of angle D is 35º and
The measure of angle F is 125
We know that :
Sum of interior angles of triangle is 180°
Now, In ΔABC:
∠A + ∠B + ∠C = 180°
35 + 20 + ∠C = 180°
55° + ∠C = 180°
∠C = 180° - 55°
∠C = 125°
Now, In ΔDEF:
∠D + ∠E + ∠F = 180°
35 + ∠E + 125 = 180°
160 + ∠E = 180°
∠E = 180° - 160°

There are 46 elements in total for 4 sets A, B, C, and D.
Consider 4 sets A, B, C, and D.
Each set has 15 elements.
The pair-wise intersection has 4 elements.
The three-way intersection has 3 elements.
There are 2 elements in the intersection of all sets.
So,
P(A) = P(B) = P(C) = P(D) = 15
P(A ∩ B) = P(A ∩ C) = P(A ∩ D) = P(B ∩ C) = P(B ∩ D) = P(C ∩ D) = 4
P(A ∩ B ∩ C) = P(A ∩ B ∩ D) = P(A ∩ C ∩ D) = P(B ∩ C ∩ D) = 3
P(A ∩ B ∩ C ∩ D) = 2
The total number of elements are:
P (A U B U C U D) = P(A) + P(B) + P(C) + P(D) - P(A ∩ B) - P(A ∩ C) - P(A ∩ D)- P(B ∩ C) - P(B ∩ D) - P(C ∩ D) + P(A ∩ B ∩ C) + P(A ∩ B ∩ D) + P(A ∩ C ∩ D) + P(B ∩ C ∩ D) - P(A ∩ B ∩ C ∩ D).
P (A U B U C U D) = 15 + 15 + 15 + 15 - 4 - 4 - 4 - 4 - 4 - 4 + 3 + 3 + 3 + 3 - 2
= 60 - 24 + 12 - 2
= 60 + 12 - 24 - 2
= 72 - 26
= 46
Therefore there are 46 elements.
