The angles ∠1 ≅ ∠4 since the line BD bisects ∠ABC, AD║ BC, and AB ║ CD. This is obtained by using the angle bisector theorem, alternate interior angles, and the transitive property of congruence.
What is the transitive property of congruence?Transitive property:
If ∠a and ∠b are congruent and ∠b and ∠c are congruent, then ∠a and ∠c are also congruent.
I.e., If ∠a ≅ ∠b and ∠b ≅ ∠c, then ∠a ≅ ∠c.
What does the angle bisector theorem state?The angles bisector theorem states that the ray or line which bisects the angle divides the angle into two equal parts.
I.e., If line BD bisects the angle ∠ABC, then ∠B = ∠B1 + ∠B2
(where ∠B1 = ∠B2)
Given:The line BD bisects ∠ABC, AD║BC, and AB║CD
Proof:The line BD bisects ∠ABC. So,
∠B = ∠3 + ∠4
According to the angle bisector theorem, ∠3 ≅ ∠4.
Since AD║BC and AB║CD, the alternate angle are congruent.
I.e., ∠3 ≅ ∠1
Thus, by the transitive property of congruence,
∠1 ≅ ∠4
Hence proved.

Which sand-castle spire has a greater volume? How much more sand do you need to make the spire with the greater volume?
Answers
Answer: spire b has the greatest volume with a volume of 64. spire a has a volume of 60. you'll need 4 in^3 more sand.
Step-by-step explanation:
since we know the volume of spire a is 60 while spire b’s volume is 64, from there, all you do is subtract 64 from 60. that gives us 4. meaning you need 4 in^3 more sand.

X=-4Step-by-step explanation:
First, we must solve for the parenthesis so...
-2x-8=4x+16
Then we must simplify this even more so lets add the 8 to 16
-2x=4x+24
Then we must subtract 4x from -2x
-6x=24
we must now divide 24 by -6 so we can isolate the x
x=-4

P varies inversely with x. If P = 12 when x = 4, find the value of P when x = −48.
Answers
Answer:
P = - 1
Step-by-step explanation:
Given P varies inversely with x the the equation relating them is
P = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition P = 12 when x = 4
12 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
48 = k
P = [tex]\frac{48}{x}[/tex] ← equation of variation
When x = - 48, then
P = [tex]\frac{48}{-48}[/tex] = - 1

Seis albañiles hicieron una barda de 180 m2 durante 12 días. ¿Cuántos días necesitaran 5 albañiles para levantar una barda de 100 m2 ?
Answers
Answer:
8 dias
Step-by-step explanation:
Primero tenemos que averiguar cuantos m2 pueden levantar los seis albañiles en 1 dia. Esto lo calculamos dividiendo los 180m2 por los 12 dias que les llevo hacerlo.
180 / 12 = 15 m2 por dia
Ahora tenemos que dividir este numero por los 6 albañiles para calcular cuantos m2 hace 1 albañil por dia
15 / 6 = 2.5
Ahora tenemos que multiplicar este m2 por los 5 albañiles que pide la pregunta
5 * 2.5 = 12.5 m2 por dia
Finalmente, necesitamos dividir los 100 m2 por los 12.5 m2 que pueden hacer los 5 albañiles por dia.
100 / 12.5 = 8 dias

What are the x-intercepts of the graph of y = (5x + 7) (2x - 1)(x – 4)?
Answers
Answer:
12x × 1x × 3x = 36x
)))))))))))))))))))
All the x - intercepts of the graph of y = (5x + 7) (2x - 1) (x - 4) will be;
⇒ - 7/5 , 1/2 , 4
What is mathematical expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The graph of the function,
⇒ y = (5x + 7) (2x - 1) (x - 4)
Now,
Find x - intercept of the equation as;
Substitute y = 0, we get;
⇒ y = (5x + 7) (2x - 1) (x - 4)
⇒ (5x + 7) (2x - 1) (x - 4) = 0
This gives three conditions as;
⇒ 5x + 7 = 0
And, 2x - 1 = 0
And, x - 4 = 0
After solve we get;
⇒ 5x + 7 = 0
⇒ x = -7/5
And, 2x - 1 = 0
⇒ x = 1/2
And, x - 4 = 0
⇒ x = 4
Hence, All the x - intercept = -7/5 , 1/2 , 4.
Therefore, All the x - intercepts of the graph of y = (5x + 7) (2x - 1) (x - 4) will be;
⇒ - 7/5 , 1/2 , 4

Answers
Answer:
$30
Step-by-step explanation:
since they exchanged them we can assume they are worth the same
250=4250
First find how many pesos is worth 1 dollar
4250/250= 17
Then divide the amount the sweater costs by how much 1 dollar would be
510/17= 30
The sweater would cost 30 dollars.
