Step-by-step explanation:
The number of ways Jenny can wear a blouse, a skirt, a pair of socks, and a pair of shoes will be 1920.
What are permutation and combination?A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
Jenny has six blouses, four different skirts, 20 different pairs of socks, and four pairs of shoes in her closet at the end of the week.
Then the number of the ways Jenny can wear a blouse, a skirt, a pair of socks, and a pair of shoes will be
Number of ways = ⁶C₁ x ⁴C₁ x ²⁰C₁ x ⁴C₁
Number of ways = 6 x 4 x 20 x 4
Number of ways = 1920

match each equation to an equivalent equation written in slope intercept form
Answer:
2x+y=3 --> y= -2x+3
2y-6=x --> y= 1/2x+3
x-3y=-6 --> y= 1/3x+2
-x+1/2y=3 --> y= 2x+6
Step-by-step explanation:
i hope this helps :)
The solution to the system of equations is
2x + y = 3 ; y = -2x + 3
2y - 6 = x ; y = ( 1/2 )x + 3
x - 3y = -6 ; y = ( 1/3 )x + 2
-x + ( 1/2 )y = 3 ; y = 2x + 6
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
a)
Let the equation be 2x + y = 3
Subtracting 2x on both sides of the equation , we get
y = 3 - 2x
So , the equation in slope intercept form is y = 3 - 2x
b)
Let the equation be 2y - 6 = x
Adding 6 on both sides of the equation , we get
2y = x + 6
Divide by 2 on both sides of the equation , we get
y = ( 1/2 )x + 3
So , the equation in slope intercept form is y = ( 1/2 )x + 3
c)
Let the equation be x - 3y = -6
Adding 3y on both sides of the equation , we get
x = 3y - 6
Adding 6 on both sides of the equation , we get
3y = x + 6
Divide by 3 on both sides of the equation , we get
y = ( 1/3 )x + 2
So , the equation in slope intercept form is y = ( 1/3 )x + 2
d)
Let the equation be -x + ( 1/2 )y = 3
Adding x on both sides of the equation , we get
( 1/2 )y = 3 + x
Multiply by 2 on both sides of the equation , we get
y = 2x + 6
So , the equation in slope intercept form is y = 2x + 6
Hence , the equations are solved

An arithmetic progression consists of 37 terms. The sum of the first 3 terms of
it is 12 and the sum of its last-3 terms is 318, then find the first and last terms
of the progression.
Answers:
First term = 1Last term (37th term) = 109=======================================================
Explanation:
a1 = first term
a2 = second term
a3 = third term
and so on, until we reach a37 to represent the 37th term
We don't know the first term, but we'll call it x for now. We'll also let d be the difference between each adjacent term, aka the common difference.
Meaning that,
a1 = xa2 = a1+d = x+da3 = a2+d = (x+d)+d = x+2da4 = a3+d = (x+2d)+d = x+3dand so on, until,
a35 = x+34da36 = x+35da37 = x+36d---------------------
Add up the first three terms (a1 through a3) and set the sum equal to 12
Then do a bit of algebra to get
a1+a2+a3 = 12
(x)+(x+d)+(x+2d) = 12
3x+3d = 12
3(x+d) = 12
x+d = 12/3
x+d = 4
x = 4-d
Do the same for the last three terms, but the sum here is 318
a35+a36+a37 = 318
(x+34d)+(x+35d)+(x+36d) = 318
3x+105d = 318
3(x) + 105d = 318
3(4-d)+105d = 318 .... replace x with 4-d; isolate d
12-3d+105d = 318
102d+12 = 318
102d = 318-12
102d = 306
d = 306/102
d = 3
The common difference is 3. It means each term is increasing by 3.
Use this value of d to find x
x = 4-d
x = 4-3
x = 1
The first term is 1. That makes the second term x+d = 1+3 = 4, then the third term is x+2d = 1+2*3 = 7, and so on.
The sum of the first three terms is 1+4+7 = 12. That helps partly confirm the answer.
Also we have,
a35 = x+34d = 1+34(3) = 103a36 = x+35d = 1+35(3) = 106a37 = x+36d = 1+36(3) = 109 is the last term (37th term)Or you could note that the 35th term is 103, and then you increase by 3 each time to get the remaining two terms.
The last part of the confirmation is adding up those three last terms: 103+106+109 = 318, so the answer is fully verified at this point.
Side note: An arithmetic sequence never ends. There technically is no "last term"; however, since we're confined to focusing on these specific 37 terms, we can get away with using the phrasing.

The volume of this cylinder is approximately 416,992 cubic inches.
The height is ___ inches.
Use ≈ 3.14.
Answer:
83
Step-by-step explanation:
height = [tex]\frac{volume}{\pi *r^{2} }[/tex]
height = [tex]\frac{416992}{3.14*(40)^{2} }[/tex]
height = 83
Answer:
Step-by-step explanation:
V = pi * r^2 * h
V = 416992
r = 40 inches.
pi = 3.14
416992 = 3.14 * 40^2 * h
416992 = 3.14 * 1600 * h
416992 = 5024 * h
416992 / 5024 = h
h = 83

¿cuanto suman los angulos interiores de un hexagono? Escribe solo el numero que corresponda a la cantidad, sin el simbolo de grados
Answer:
La suma de los ángulos interiores de un hexágono regular es 720°
Step-by-step explanation:
Asumamos que el hexágono presentado en el enunciado sea regular, el cual es formado por seis triángulos equiláteros, Un ángulo interno del hexágono está formado dos ángulos laterales y vecinos de dos triángulos equiláteros, es decir, dos veces 60°, o sea, 120°. Si el hexágono regular tiene seis ángulos internos de igual medida, entonces la suma de los ángulos interiores es 720°.

Express as fraction
x/6 = 4/8
Multiply both sides by 6
x = 6 * 4/8
Evaluate the product
x = 3
