given m||n,find the value of x
Answer:
8x+5 + 2x+5 = 180
10x+10=180
10x =170 = x = 17
Step-by-step explanation:
Answer:
answer: x = 17 Hope this helps!
2 x 17 + 5 = 39 8 x 17 + 5 = 141
Straight angles are 180 degrees
39 + 141 = 180
So x = 17
Mackenzie made 38 of 50 free throws. What is the
experimental probability that Mackenzie will NOT
make the next free throw she attempts?
A- 6/25
B- 12/25
C- 19/25
D- 21/25
A I believe because Against the odds of 38/50 would be 12/50 that is not an option so split in half this would be A cause its an equivalent fraction

What is the volume of the composite solid? 6 m 4 m 3 m 4 m 4 m
Answer:
Please read explanation
Step-by-step explanation:
A picture would be helpful, but I think the answer might be (6x4x3)+(3x4x4). If your shape is made up of many parts, you should find the volume of each shape then add them up to find the total volume. (To find volume, multiply base x height x width) If you could give a picture, it would be very helpful because I don't really know which numbers I should multiply to find volume. I hope this explanation helps, and please comment if you need to ask me anything.

The temperature at midnight is -5°C and is expected to drop 12°
by sunrise. What is the expected temperature at sunrise?
Answer:
-17 degrees Celsius.
Step-by-step explanation:
If the temperature at midnight is -5, and it is supposed to drop 12 more by sunrise, the 12 degrees are subtracted from the initial temperature.
-5 - 12 = -17 degrees by sunrise.

find the volume of the composite figure
Answer:
8064
Step-by-step explanation:
Multiply all the sides
6x4x12x2x14
Answer:
384 cu. cm
Step-by-step explanation:
The figure is comprised of two rectangular prisms. One prism has dimensions of 6, 4 and 2 and the other prism has dimensions of 14, 12 and 2
Vol of a rectangular prism = lwh
Total volume = 6(4)(2) + 14(12)(2)
= 48 + 336
= 384 cu. cm
Write the equation of the line that passes through (−3,1) and (2,−1) in slope-intercept form
Answer:
[tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]
Step-by-step explanation:
The equation of a line is y = mx + b
Where:
m is the slopeb is the y-interceptFirst, let's find what m is, the slope of the line.
Let's call the first point you gave, (-3,1), point #1, so the x and y numbers given will be called x1 and y1.
Also, let's call the second point you gave, (2,-1), point #2, so the x and y numbers here will be called x2 and y2.
Now, just plug the numbers into the formula for m above, like this:
[tex]m = -\frac{2}{5}[/tex]
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:
[tex]y=-\frac{2}{5}x + b[/tex]
Now, what about b, the y-intercept?
To find b, think about what your (x,y) points mean:
(-3,1). When x of the line is -3, y of the line must be 1. (2,-1). When x of the line is 2, y of the line must be -1.Now, look at our line's equation so far: [tex]y=-\frac{2}{5}x + b[/tex]. [tex]b[/tex] is what we want, the -[tex]-\frac{2}{5}[/tex] is already set and x and y are just two 'free variables' sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-3,1) and (2,-1).
So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!
You can use either (x,y) point you want. The answer will be the same:
(-3,1). y = mx + b or [tex]1=-\frac{2}{5} * -3 + b[/tex], or solving for b: [tex]b = 1-(-\frac{2}{5})(-3)[/tex].[tex]b = -\frac{1}{5}[/tex]. (2,-1). y = mx + b or [tex]-1=-\frac{2}{5} * 2 + b[/tex], or solving for b: [tex]b = 1-(-\frac{2}{5})(2)[/tex]. [tex]b = -\frac{1}{5}[/tex].See! In both cases, we got the same value for b. And this completes our problem.
The equation of the line that passes through the points (-3,1) and (2,-1) is [tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]

Answer:
x = 6
y = 6[tex]\sqrt{2}[/tex]
z = 12
Step-by-step explanation:
the ratio of sides in a 30-60-90° triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2
therefore, 'x' must have a measure of 6
which means the hypotenuse must have a measure of 12
other triangle is a 45-45-90° triangle whose sides are in a ratio of 1 to [tex]\sqrt{2}[/tex]
this means that 'y' must be 12/[tex]\sqrt{2}[/tex] which is 6[tex]\sqrt{2}[/tex]
'z' must be 6[tex]\sqrt{2}[/tex] · [tex]\sqrt{2}[/tex] = 12
Para reunir dinero para su gira de estudios , los alumnos de un curso deciden vender números de una rifa que se encuentran numeradas del 1 al 100 ¿Cual es la probabilidad de ganar en la rifa si se compran todos los numeros que sean multiplos de 3 o de 5?
Respuesta:
0.53
Explicación:
Para calcular la posibilidad del evento A: "ganar la rifa comprando todos los números múltiplos de 3 o 5", debemos usar la siguiente fórmula.
P(A) = casos favorables / casos posibles
Evaluemos primero todos los casos que son múltiplos de 3, entre 1 y 100: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99. En total son 33.
Ahora, evaluemos todos los casos que son múltiplos de 3, entre 1 y 100: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100. En total son 20.
El número total de casos favorables es 33 + 20 = 53.
El número de casos posibles es el total de números de 1 a 100, es decir 100.
Luego P(A) = 53/100 = 0.53.

Answer:
y=63, x=20, x=47, b=70, c=89, x=133
Step-by-step explanation:
1) y=63- alternate angles are the same
2) 4x+5x=180
9x=180
x=20
3) x=47
4) b=70- angles on a line equal to 180
c=89- angles in a triangle add up to 180
5) x=133- angles that are alternate are the same

find the value of the variable and the length of each chord. round your answers to the nearest tenth
Answer:
x = 3, JL = 17, MN = 13
Step-by-step explanation:
Given 2 intersecting chords in a circle , then
The product of the parts of one chord is equal to the product of the parts of the other chord, that is
14x = 7 × 6 = 42 ( divide both sides by 14 )
x = 3
Then
JL = x + 14 = 3 + 14 = 17
MN = 6 + 7 = 13
