Find the measure of the vertex angle ∠ABD of an isosceles triangle
we know that
An isosceles triangle has two equal sides and two equal angles
In this problem
∠ABD=∠BAD= ----> the angles of the base are equals
Find the measure of the vertex angle
∠ABD= ------> the sum of the internal angles of a triangle is equal to
Step 2
Find the measure of the angle ∠CBD in the equilateral triangle
we know that
A equilateral triangle has three equal sides and three equal angles
The measure of the internal angle in a equilateral triangle is
so
∠CBD=
Step 3
Find the measure of the angle ∠ABC
∠ABC=∠ABD+∠DBC
substitute the values
∠ABC=
therefore
the answer is
the measure of the angle ∠ABC is

Ms. Hamm bought a new car for $37,500. It is said that her car depreciates at a rate of 7% each year
Answers
Answer:
This would mean that the next year her car's value would go down by $2,625. The new value of the car would consequently be $34,875.
Step-by-step explanation:Here is how you can solve this problem:
Okay, so first, let's find 7% of $37,500. To do this, the simple way would be to find first 1% of $37,500. 1% of $37,500 is $375. This is because you are moving the decimal point two spaces to the left.Now that we know that 1% of $37,500 is $375, let's multiply this value by 7.
375 x 7 = 2625.Subtract 2625 from 37,500.You will get $34,875.Let's say that the next year, her car value goes down by 7% again.
THIS IS THE IMPORTANT PART:
YOU FIND 7% OF THE NEW VALUE, NOT $37,500. YOU WOULD FIND 7% OF $34,875.
Hope this helps! :)

What is 7/12+5/6?
Add the fractions, please
Answers
Answer:
1 5/12
Step-by-step explanation:
first we have to convert the denominator(bottom number) to 12
6x2=12
Now we have to multiple 2 to the numerator(top number)
since we have to do the same to the top and bottom
5x2=10
now we add the fractions
7/12+ 10/12=17/12
now we simplify the fraction
17/12= 1 5/12
hopefully you understand how to do it.

What is the end behaviour of this radical function?
[tex] f(x) = - 2 \sqrt[3]{x + 7} [/tex]
Answers
Answer: The square root function f(x)=√x has domain [0,+∞) and the end behaviour is. as x→0 , f(x)→0. as x→∞ , f(x)→∞. Note: "end behavior"
Step-by-step explanation:
So, the sign of the leading coefficient is sufficient to predict the end behavior of the function. To predict the end-behavior of a polynomial function, first check whether the function is odd-degree or even-degree function and whether the leading coefficient is positive or negative.
The end behavior of the function is, when x approaches positive infinity, f(x) approaches negative infinity.
Option A is correct.
End behavior of function:We have to find the end behavior of the given radical function.
To check end behavior, we have to check limit of function at x tends to infinity and x tends to minus infinity.
Given function are,
[tex]f(x)=-2\sqrt[3]{x+7}[/tex]
We can not put [tex]x=-\infty[/tex], because variable under square root must be greater than equal to zero.
When we check limit at [tex]x=\infty[/tex].
[tex]\lim_{x \to \infty} f(x)= \lim_{x \to \infty} -2\sqrt[3]{x+7}=-\infty[/tex]
Hence, the end behavior of the function is, when x approaches positive infinity, f(x) approaches negative infinity.

El lugar donde la linterna, los bancos y los árboles se encuentran nuevamente está a 300 metros del punto de inicio.
Step-by-step explanation:
Los parámetros dados son;
El espacio entre las linternas = 30 metros.
El espacio entre los bancos = 20 metros.
El espacio entre los árboles = 50 metros.
Por lo tanto, tenemos, la ubicación donde la linterna, los bancos y los árboles se encuentran nuevamente, está dada por el mínimo común múltiplo de cada una de sus distancias de separación individuales como sigue;
2 divide 30 20 50 [tex]{}[/tex]
[tex]{}[/tex] 5 divide 15 10 25
