If ZBPD and ZDPC have a sum of 72°. What is ZAPC?
A. 180.
B.90.
C.180.
D.18.
Hey there!
I don't know if it's too late, but oh well: The answer is 108°
Knowing that supplementary angles add up to 180°, and we also know that we have 2 out of 3 of the angle measures, so we can subtract that from 180:
180 - 72 =108°
Have a terrificly amazing day!
Answer:
∡APC = 108°
Step-by-step explanation:
∡ APB = 180°
∡ DPB + ∡ CPB + ∡APC = 180°
∡ BPD and ∡DPC have a sum of 72°
then:
72° + ∡APC = 180°
∡APC = 180° - 72°
∡APC = 108°

Answer:
X = 36/17
y = -8/17
Step-by-step explanation:
Since they both equal y, you could use them equal to each other.
(5/2)x-4=(-1/3)x+2
Then solve for x by combining like terms. X should be 36/17. Plug in x to find y in one of the equations. I will use the top one. (5/3)(36/17)-4=y. That should simplify down to (60/17)-4=y. Y would finally equal -(8/17).

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9).
(2, -2)
(1, -4)
(4, -4)
Answer:
The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)
Step-by-step explanation:
Given two points are:
(-2, 5) and (6, -9)
The mid-point is the point that divides a line segment in two equal parts.
Let M be the mid-point then
[tex]M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
Let
(x1,y1) = (-2, 5)
(x2,y2) = (6, -9)
Putting the values in the formula, we get
[tex]M(x,y) = (\frac{-2+6}{2}, \frac{5-9}{2})\\M(x,y) = (\frac{4}{2}, \frac{-4}{2})\\= (2,-2)[/tex]
Hence,
The midpoint of the line segment whose endpoints are (-2, 5) and (6, -9) is: (2,-2)

In a survey of 3,200 people who owned a certain type of car, 960 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
HELP NOW!!
Answer: let
Total number of those who took part in the survey (T)=3200
Those who were satisfied (t)=960
Percentage of those who were satisfied (S)=(t/T)*100
S=(960/3200)*100
S=30%
Therefore only 30% were satisfied
Step-by-step explanation:
Thirty percent of the people surveyed were satisfied with the car.
What is the formula used to find the percentage?The formula used to calculate percentages is the ratio of value to total value multiplied by 100.
Let's denote T as the total number of people who owned a certain type of car and t as the number of people who were satisfied with the car.
Given that,
T =3200
t= 960
The percent of people satisfied with the car is obtained by using the below equation.
[tex](\frac{t}{T} ) * 100[/tex]
(960/3200)*100 = 30%
As a result, the percentage of people who are satisfied with the car is 30%.

imagine you're in a queue to the airport check-in desk if two-thirds of the queue is in front of you and three tenths of the queue is behind you how many people are in the queue
Step-by-step explanation:
Let x be the number of people in the queue, including yourself.
We have 2/3 x + 1 + 3/10 x = x.
=> 29/30 x + 1 = x
=> x/30 = 1
=> x = 30.
Hence there are 30 people in the queue.

One cell phone company charges a $76 sign-up fee and $40 per month. Another cell phone company charges $136 sign-up fee and $20 per month. Write and solve an equation to determine after how many months the cost is the same
Answer:
The cost would be same after 3 months.
Step-by-step explanation:
Given that:
Charges of first company;
Sign up fee = $76
Per month charges = $40
Let,
x be the number of months
y be the total cost.
y = 40x + 76 Eqn 1
Charges of second company;
Sign up fee = $136
Per month charges = $20
y = 20x + 136 Eqn 2
For same cost,
Eqn 1 = Eqn 2
40x + 76 = 20x + 136
40x-20x = 136 - 76
20x = 60
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{60}{20}\\x=3[/tex]
Hence,
The cost would be same after 3 months.
how many solutions does 6x−y=−1 6x+y=−1
Answer:
x=−1/6 and y=0
Step-by-step explanation:
Answer:
There is one solution.
Step-by-step explanation:
x = - 1/6
y = 0
It can be solved simultaneously
6x - y = -1
6x + y = -1
Subtract equation two from equation one
-2y = 0
Divide both sides by-2
y = 0/-2
y = 0
Substitute 0 for y in either of the equations to get x
6x - 0 = -1
6x = -1
Divide both sides by 6
x = -1/6

Step-by-step explanation:
just do the inequality and graph
Does anyone know how to do this?? Help please!!!!
Answer:
When we have a rational function like:
[tex]r(x) = \frac{x + 1}{x^2 + 3}[/tex]
The domain will be the set of all real numbers, such that the denominator is different than zero.
So the first step is to find the values of x such that the denominator (x^2 + 3) is equal to zero.
Then we need to solve:
x^2 + 3 = 0
x^2 = -3
x = √(-3)
This is the square root of a negative number, then this is a complex number.
This means that there is no real number such that x^2 + 3 is equal to zero, then if x can only be a real number, we will never have the denominator equal to zero, so the domain will be the set of all real numbers.
D: x ∈ R.
b) we want to find two different numbers x such that:
r(x) = 1/4
Then we need to solve:
[tex]\frac{1}{4} = \frac{x + 1}{x^2 + 3}[/tex]
We can multiply both sides by (x^2 + 3)
[tex]\frac{1}{4}*(x^2 + 3) = \frac{x + 1}{x^2 + 3}*(x^2 + 3)[/tex]
[tex]\frac{x^2 + 3}{4} = x + 1[/tex]
Now we can multiply both sides by 4:
[tex]\frac{x^2 + 3}{4}*4 = (x + 1)*4[/tex]
[tex]x^2 + 3 = 4*x + 4[/tex]
Now we only need to solve the quadratic equation:
x^2 + 3 - 4*x - 4 = 0
x^2 - 4*x - 1 = 0
We can use the Bhaskara's formula to solve this, remember that for an equation like:
a*x^2 + b*x + c = 0
the solutions are:
[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
here we have:
a = 1
b = -4
c = -1
Then in this case the solutions are:
[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*1*(-1)} }{2*(1)} = \frac{4 +- 4.47}{2}[/tex]
x = (4 + 4.47)/2 = 4.235
x = (4 - 4.47)/2 = -0.235
