We have:
ab = bc (hypothetical)
so the triangle ABC is isosceles at B
we have: bd is the height of the triangle ABC, so BD is perpendicular to AB
Consider the triangle ABD and the right triangle ACD have:
AB = BC (hypothesis)
BD is the common edge
So the triangle ABD = triangle ACD (hypotenuse - acute angle)
hence the angle ABD = angle ACD

Which is the length of the hypitenuse?
Answer:
20
Step-by-step explanation:
the length of the hypotenuse of a right triangle can be found using the Pythagorean theorem which states that the square of the length of the hypothesis equal the sum of the square of the length of the other two sides

Find the Discount % if the OriginalPrice is $15 and the Sale Price is $14.25.
Answer:
5%
Step-by-step explanation:
15-14.25/15
original - sale price divided by original = percent change
15-14.25/15 = 0.75/15 = 0.05 = 5%
In a sale all items are reduced by 15%. A carpet now costs £15.30 per square metre. What was the price before the sale?

The radius of a circle is 3/4 inches. How many inches is the diameter?
Step-by-step explanation:
Given
In a circle
Radius (r) = 3 / 4 inches
Diameter (d)
= 2 * r
= 2 * 3 /4
= 3 /2 inches
Hope it will help :)❤
The diameter of a circle with a radius of 3/4 inches is 6/4 inches.
We are given that;
The radius of a circle = 3/4 inches
Now,
The diameter of a circle is twice the radius of the circle. Therefore, to find the diameter of a circle with a radius of 3/4 inches, we need to multiply 3/4 by 2. We can do this by multiplying the numerators and the denominators:
(3/4) x 2 = (3 x 2)/(4 x 2) = 6/8
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:
6/8 = (6/2)/(8/2) = 6/4
Therefore, by the circle the answer will be 6/4.

Step-by-step explanation:
y = -x + 1
y - 1 = -x
y = -x + 1
y = -x + 1 (Multiply by -1)
y = -x + 1
-y = x - 1
0 = 0
Since 0 = 0 is true, this is an identity solution that has an infinite set of solutions

An arctic wooly bear caterpiller lives for 7 years and spends 90% of its life frozen. How many days of its life is the arctic wolly bear frozen.
Answer:
The arctic wolly bear is frozen 2,299.5 days of its life.
Step-by-step explanation:
With the information provided, first, you have to calculate the number of days in 7 years by multiplying 7 years for 365 that is the number of days in a year:
7*365=2,555
Then, you have to calculate 90% of 2,555 since the statement indicates that the arctic wooly bear caterpiller spends 90% of its life frozen:
2,555*90%=2,299.5
According to this, the answer is that the arctic wolly bear is frozen 2,299.5 days of its life.
Al precio de p dólares por unidad, se venden x unidades de cierto artículo al mes en el mercado con p=50-0.5x ¿Cuántas unidades como mínimo se deben vender cada mes con el objetivo de tener ingresos de por lo menos de 1.200 dólares?
Answer:
Se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.
Step-by-step explanation:
De acuerdo con el enunciado, [tex]x[/tex] es la cantidad mínima de artículos a un precio de [tex]p[/tex]. Además, los ingresos totales deben ser de un mínimo de 1200. En consecuencia, tenemos el siguiente sistema de ecuaciones:
[tex]x \cdot p = 1200[/tex] (1)
[tex]p = 50-0.5\cdot x[/tex] (2)
Aplicando (2) en (1), tenemos la siguiente ecuación polinómica:
[tex]x\cdot (50-0.5\cdot x) = 1200[/tex]
[tex]50\cdot x -0.5\cdot x^{2} = 1200[/tex]
[tex]0.5\cdot x^{2}-50\cdot x +1200 = 0[/tex] (3)
Por la Fórmula de la Cuadrática tenemos las raíces del polinomio:
[tex]x_{1} = 60[/tex], [tex]x_{2} = 40[/tex]
De acuerdo con el resultado anterior, se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.
