Use the formula for the trapeze
Step-by-step explanation:
Answer:
∠ C = 88°
Step-by-step explanation:
The opposite angles in a cyclic quadrilateral sum to 180°, then
8x - 4 + 7x + 4 = 180 , that is
15x = 180 ( divide both sides by 15 )
x = 12
Then
∠ C = 7x + 4 = 7(12) + 4 = 84 + 4 = 88°

Answer:
3x + 2 = 3
Step-by-step explanation:
3x + 2 = 3 Subtract 2 from both sides
3x = 1 Divide both sides by 3
x = 1/3

En un salon de una academia solo asisten a un examen los 3/4 de los alumnos y de estos aprueban los 4/5 ; si los desaprobados son 21 ¿cuantos alumnos hay en dicha aula?
Answer:
Hay 140 alumnos en dicha aula.
Step-by-step explanation:
Primero, debes encontrar la cantidad de alumnos que aprobaron que corresponde a 4/5 usando una regla de tres teniendo en cuenta que sabes que 1/5 corresponde a 21 que son los estudiantes que no aprobaron:
1/5 → 21
4/5 → x
x=(4/5*21)/1/5
x=(84/5)/(1/5)
x=84*5/5*1
x=420/5
x=84
Ahora, puedes sumar el número de estudiantes que aprobaron con el número de estudiantes que no aprobaron para encontrar el total que estudiantes que asistieron al examen:
84+21=105
Después, dado que sabes que 105 estudiantes corresponde a 3/4 de los alumnos en un aula, puedes usar una regla de tres para encontrar el número de estudiantes en el aula:
3/4 → 105
1 → x
x=(1*105)/(3/4)
x=(105/1)/(3/4)
x=105*4/1*3
x=420/3
x=140
De acuerdo a esto, la respuesta es que hay 140 alumnos en dicha aula.

(x2+3x+2)+(3x2–x+1) Use algebra to find the sum
Answer: -2x²+2x+3
Step-by-step explanation:
Factoring -2x2+2x+3
The first term is, -2x2 its coefficient is -2 .
The middle term is, +2x its coefficient is 2 .
The last term, "the constant", is +3
Step-1 : Multiply the coefficient of the first term by the constant -2 • 3 = -6
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is 2 .
-6 + 1 = -5
-3 + 2 = -1
-2 + 3 = 1
-1 + 6 = 5
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

what is 15 divided by pina colada= 1.43/8
Answer:
111.678
Step-by-step explanation:
simplify within parenthesis
Answer:
First Space: 49
Second Space: 33
Third Space:-99
Fourth Space: -99
Fifth Space: 10
Sixth Space: -89
Step-by-step explanation:
First Space: for the first space you would do -7 times -7 because it is squared so you would get 49 because a negative and a negative and a negative make a positive.
Second Space: For the second space you have to do 49-16 because you already found the first space and the answer would be 33.
Third Space: For the third space you would do the answer you got from the second space which is 33 and multiply by -3 because -3 is outside the brackets. The answer would be -99.
Fourth Space: You would just put the same thing as the third space and put -99.
Fifth space: To find the fifth space you have to do 4 ÷ 2/5. To find this part you have to do 4 times the reciprocal (when you flip the fraction) and you would get 4 times 5/2. Then you can cross the denominator (bottom of the fraction) and make the 4 a 2 because 4 ÷ 2=2. Next you do 2 times 5 and get 10 as a answer.
Sixth Space: For the final answer you would use the fourth and fifth space. You would do -99+10 which is -89.

570=95n
divide both side by 95
Answer:
6 Months
Step-by-step explanation:
95 x 6 is 570. If you add the set up fee, it comes down to 615 dollars.

Help me real fast with this one
Answer:
The answer should be 75 if i did the math right
Answer:
Step-by-step explanation:
You have to add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
So in this case it would be:
46+56+64+64+72+76+77+82+94+96+99.
And the answer for the first step is: 826.
Next Step!
826 will have to be divided by 11.
Because there are 11 numbers that had to be added.
So 826÷11=75.
I hope this helps :)If you are taking a test at 8:30 am and it takes you 2 1/2 hours what time would it be? PLEASE ANSWER
Answer:
11:00
Step-by-step explanation:
This is easier than I thought...
So 8:30+2 is 10:30
...and now we have 1/2 left.
1/2 in this case of time would be 30
So, 10+30+30 would be 10:60
Now all we have to do is simplify it
60 minutes= 1 hour
So...
10:60-60=10
10+1=11
11 AM is the correct answer!
Hope this helps! :D
