Answer:
x = 23
Step-by-step explanation:
2x + 19 + 5x = 180
I say this because it is an angle that is equivalent to the one adjacent to 2x+19, which is on a straight line. That means it is equal to 180.
7x + 19 = 180
180 - 19 = 7x
161/7 = x
x = 23
Step-by-step explanation:
5x+2x+19=180
7x+19=180
7x=180-19
7x=161
x=161/7
x=23

There are red, blue, and white buttons in a box. The ratio of the
number of red buttons to the number of white buttons is 4:7.
The ratio of the number of blue buttons to the number of red buttons
is 3:2. There are 280 white buttons. How many buttons are there
altogether?
Please Help i’m very confused!!!
Answer:
There are 680 buttons altogether
Step-by-step explanation:
Here, we want to get the total number of buttons
From the question, the ratio of number of red to white buttons is 4:7
mathematically, this mean;
r:w = 4:7 = ?/280
thus;
4/7 = ?/280
7 * ? = 280 * 4
? = (280 * 4)/7
? = 40 * 4 = 160
From here, we can see that the number of white buttons is 160
from the second part of the question,
b:r = 3:2 = ?:160
3/2 = ?/160
2 * ? = 160 * 3
? = 480/2
? = 240
Thus, we have the sum total of the number of buttons as;
240 + 280 + 160 = 680
Given a triangle with side PQ=8 cm. To get a line PQ’=3/4 of PQ, we divide the line segment PQ in the ratio
Answer:
PQ' : Q'Q = 3 : 1
Step-by-step explanation:
As Given In Question
We Have A Triangle With Side PQ=8cm
PQ' = 3/4 * PQ
PQ' = 3/4 * 8
PQ' = 6 cm
& Q'Q = PQ - PQ'
= 8 - 6 = 2cm
so the line segment PQ is divided into PQ' : Q'Q = 3 : 1

Answer: sqrt(2)/2 which is choice D
======================================================
Explanation
(3pi/4) radians converts to 135 degrees after multiplying by the conversion factor (180/pi).
The angle 135 degrees is in quadrant 2. We subtract the angle 135 from 180 to find the reference angle
180-135 = 45
Then you can use a 45-45-90 triangle to determine that the ratio of opposite over hypotenuse is sqrt(2)/2
sine is positive in quadrant 2
------------
Alternatively, you can use a unit circle. Refer to the diagram below. In red, I've circled the angle 3pi/4 radians. The terminal point for this angle has a y coordinate of sqrt(2)/2
Recall that y = sin(theta).
In the diagram,AB= 6 cm, BD= 17 cm, CD= 15 cm, ABC= BCD= 90°.
Find the lengths of BC and AC.
The required values are :

Un vendedor de frutas tiene cierto número de mangos, vende 3/5 de ellos más dos mangos; luego vende 1/3 de los restantes más dos mangos, luego vende la mitad del saldo más un mango. Finalmente vende los 24 restantes, el número de mangos inicial empieza con la cifra
Respuesta:
200 mangos
Explicación paso a paso:
Dado :
Sea el número inicial de mangos = x
Primera venta:
3 / 5x + 2
Número a la izquierda = x - (3 / 5x + 2) = 2 / 5x - 2
Segunda venta:
1/3 (2 / 5x - 2) + 2 = 2 / 15x - 2/3 + 2
Cantidad restante:
2 / 5x - 2 - (2 / 15x - 2/3 +2)
2 / 5x - 2 - 2 / 15x + 2/3 - 2
0,2666666x - 3,3333
Tercera venta:
1/2 (0,2666666x - 3,3333) + 1 = 0,133333x - 1,666665 + 1
0.2666666x - 3.3333 - (0.133333x - 1.666665 + 1) = venta final
0,2666666x - 3,3333 - (0,133333x - 1,666665 + 1) = 24
0,2666666x - 3,3333 - 0,133333x + 1,666665 - 1 = 24
0,133333x - 2,666635 = 24
0.133333x = 24 + 2.666635
0,133333x = 26,666635
x = 26,666635 / 0,133333
x = 200.00026
x = 200 mangos

Find the area of the shaded region for the given figure in terms of x.
X-1
X + 2
X-1
X + 2
Answer:
Area of the shaded region = (6x + 3)
Step-by-step explanation:
Area of the shaded region = Area of the large rectangle - Area of the small rectangle
Area of the large rectangle = Length × Width
= (x + 2)(x + 2)
= (x + 2)²
= x² + 4x + 4
Area of the small rectangle = (x - 1)(x - 1)
= (x - 1)²
= x² - 2x + 1
Area of the shaded region = (x² + 4x + 4) - (x² - 2x + 1)
= 6x + 3
Area of the shaded region = (6x + 3)

Find the area of the following triangle enter the exact answer as a decimal
Answer:
75.06239187
Step-by-step explanation:
1/2bh= Area of a Triangle
6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.
36+b^2=72.25
b^2=36.25
b=6.02
6.02+19= base
25.02
Now area
1/2bh
1/2 (25.02*6)
25.02*6= 150.1247
150.1247/2= 75.06239187 is Area
The above decimals before area are rounded.

Answer:
x =6
Step-by-step explanation:
The angles are alternate interior angles and alternate interior angles are equal
7x = x+36
Subtract x from each side
7x -x = x+36-x
6x = 36
Divide by 6
6x/6 = 36/6
x = 6
Write a linear equation in two variables to represent the following statement
"the number of Red balls is half the number of the Blue ones"
Answer:
y = x/2
Step-by-step explanation:
Let y represent the number the number of red balls and let x represent the number of blue balls. Since we have that the number of Red balls is half the number of the Blue ones, and the number of red balls equals x, we divide x by 2. So, x/2.
Since x/2 is equal to the number of blue balls and y is the number of blue balls, we write y = x/2.
So, our linear equation in two variables that represents "the statement the number of Red balls is half the number of the Blue ones" is
y = x/2

S and T are subsets of a universal set, U, such that: U = {a, b, c, d, e, f, g, h, i} S = {a, b, e} T = {a, d, f, g}. What are the elements of S ⋃ T?
Answer:
S∪B = {a,b,e,a,d,f,g}
Step-by-step explanation:
According to the Question,
Given, S and T are subsets of a universal set U ( U = {a, b, c, d, e, f, g, h, i} )
And, S = {a, b, e} , T = {a, d, f, g}
Thus, S∪B(S union B) = n(S) + n(T)
S∪B = {a,b,e,d,f,g} (There It contains all the elements present in S & B).

Find all positive and negative integers b such that x2 +bx+6 factors
Answer:
b = - 5 , - 7 , 5 , 7
Step-by-step explanation:
Standard quadratic equation is of the form :
ax² + b x + c , where b = p + q and c = pq
Where p and q are factors of c.
Therefore , we will consider the factors of 6.
Factors of 6 = ( -1 , -6 ) , ( -2 , -3 ) , ( 1, 6 ) , ( 2 , 3)
x² + bx + 6
b = p + q
So, b = - 7 , -5, 7 , 5
