Answer:
110 degrees
Step-by-step explanation:
Ok so in a quadrilateral, the sum of the interior angles have to add up to 360 degrees*.
This means that x + 128 + 82 + 40 = 360, so you can solve this as an equation:
x + 128 + 82 + 40 = 360
x + 250 = 360
x = 110 degrees
*The reason the interior angles of a quadrilateral add up to 360 degrees is because the formula for the sum of the interior angles in a polygon is
180 * (n - 2) where n is the number of sides, so since this polygon has 4 sides it would be:
180 * (4 - 2)
180 * 2
360 degrees
Hope that makes sense!

Diana has 3/4 foot of ribbon. She used 1/3 foot to make a bow for her doll. How much ribbon, in feet, is left over?
Answers
Answer: 5/12
Step-by-step explanation: you first need to make the denominators of the fractions equivalent. The least common factor of 3 and 4 is 12. 3/4 becomes 9/12 and 1/3 becomes 4/12. Now you can subtract. 9/12 - 4/12 = 5/12

SE TIENE UNA PARED PARA ENCHAPAR DE 5 METROS DE BASE X 2 METRS DE ALTURA , Y LOS BALDOSINES PARA ENCHAPAR TIENE 25CM DE ALTURA Y 10 CM DE BASE CUANTOS BALDOSINES SE NESECITARAN PARA ENCHAPAR LA PARED
Answers
Answer:
Se necesitan 400 baldosines para cubrir la pared.
Step-by-step explanation:
Primero debemos encontrar el área de la pared:
[tex] A_{p} = b_{p}*h_{p} [/tex]
En donde:
[tex] A_{p}[/tex]: es el área de la pared
[tex]b_{p}[/tex]: es la base de la pared = 5 m
[tex]h_{p} [/tex]: es la altura de la pared = 2 m
[tex] A_{p} = 5 m*2 m = 10 m^{2} [/tex]
Ahora debemos encontrar el área de los baldosines:
[tex] A_{b} = b_{b}*h_{b} [/tex]
[tex] A_{b} = 10 cm*25 cm = 250 cm^{2}*\frac{1 m^{2}}{(100 cm)^{2}} = 0.025 m^{2} [/tex]
Si un baldosin cubre 0.025 metros cuadrados de pared, para cubrir 10 metros cuadrados necesitamos:
[tex] N_{B} = \frac{1 B}{0.025 m^{2}}*10 m^{2} = 400 [/tex]
Por lo tanto, se necesitan 400 baldosines para cubrir la pared.

Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

What value of y makes the equation below true?
y + 29 = 11
A. 81
B. 8.9
C. 9.1
D. 13.9
Answers
Answer:
y = -18
Step-by-step explanation:
Given that,
y+29 =11
We need to find the value of y.
Subtract 29 to both sides of the above equation.
y+29-29 =11-29
y = -18
So, the value of y is equal to -18.

28 students travel on a field trip. They bring a van that can seat 12 students. Elena and Kiran's teacher asks other adults to drive cars that seat 3 children each to transport the rest of the students.
Answers
Answer:
Step-by-step explanation:
Yes, she can use this inequality and it does matter since the number of cars that the inequality provides will need to be equal to or more than that number in order for all the students to be able to go. Therefore, if we apply the inequality it would give us the minimum number of cars needed (n) like so
12 + 3n > 28 ... subtract 12 on both sides
3n > 16 ... divide both sides by 3
n > 5 1/3
Since there can't be 1/3 of a car and the number of cars needed must be higher than 5 1/3 then we would need a total of 6 cars to take all of the children.
