Step-by-step explanation:
In this rug, given the horizontal segments are parallel and ∠1 ≅ ∠2, prove ∠3 ≅ ∠5.
1 is congruent to 3 and 2 is congruent to 5 because alternate interior angles are congruent.
Since 1 is congruent to 3 and to 2, then 3 is congruent to 2.
But 2 is congruent to 5, so since 3 is congruent to both 3 and 5, 3 and 5 must be congruent to each other.
What is being congruent in math?Two geometric figures are said to be congruent or to be in the relation of congruence if it is possible to superpose one of them on the other so that they coincide throughout.
The word 'congruent' means 'exactly equal' in terms of shape and size. Even when we turn, flip, or rotate the shapes, they remain equal. For example, draw two circles of the same radius, then cut them out and place them on one another.
What is an alternate interior angle?Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal.

StartFraction y Over x EndFraction = two-thirds
StartFraction y Over 2 EndFraction = StartFraction 3 Over x EndFraction
StartFraction y Over 3 EndFraction = StartFraction x Over 2 EndFraction
Mark this and return
Answer:B mark me brainliest
Step-by-step explanation:Recall that slope is rise over run
slope = rise/run
The rise being the change in y, while the run is the change in x.
So we could informally think of it as slope = y/x
-----------
Since we're told that it "has a rise of 2 and run of 3", this means slope = 2/3.
The slope is both y/x and also 2/3.
Equating the two expressions leads us to y/x = 2/3. This is why choice B is the final answer.

B) y/x=2/3

How many solutions does the equation 2x + .5y = -4 have?
Answer:

2x-5y=4. 2x−5y=4. Add 5y to both sides. Add 5y to both sides.
2x=4+5y. 2x=4+5y. The equation is in standard form. The equation is in standard form.
2x=5y+4. 2x=5y+4. Divide both sides by 2. ...
\frac{2x}{2}=\frac{5y+4}{2} 22x=25y+4 Dividing by 2 undoes the multiplication by 2. ...
x=\frac{5y+4}{2} x=25y+4 Divide 4+5y by 2.
Step-by-step explanation: How do I determine how many solutions an equation has?
If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.

The line passes through (8,-7) and is parallel to the line whose equation is y=2x+2.
Answer:
y = 2x -23
Explanation:
Given equation: y = 2(x) + 2
Comparing with slope intercept formula: y = m(x) + b
where m is slope, b is y-intercept
Here slope: 2 as parallel line has same slope
Find equation:
y - y1 = m(x-x1)
y -(-7) = 2(x-8)
y + 7 = 2x - 16
y = 2x - 16 - 7
y = 2x -23

Step-by-step explanation:
remember, a probability is always desired cases over total possible cases.
the class has 10+15 = 25 students.
and 5 of them will be picked as representatives to the school board.
how many total possibilities do we have ?
since picked students can be picked only once, and the sequence of the 5 picked students in the group does not matter, we have a combination without repetition :
C(25, 5) = 25! / (5! × (25-5)!) = 25! / (5! × 20!) =
= 25×24×23×22×21 / (5×4×3×2) =
= 5×1×23×22×21 = 53,130 possible outcomes.
how many desired outcomes ?
that would be how many options we have to pick 2 out of 10 and 3 out of 15 :
C(10,2) × C(15,3) = 10! / (2 × 8!) × 15! / (3! × 12!) =
= 10×9/2 × 15×14×13/(3×2) =
= 5×9 × 5×7×13 = 20,475 desired outcomes
and the probability is
20475 / 53130 = 4095 / 10626 = 1365 / 3542 = 195 / 506
= 0.385375494... ≈ 0.39

BUILDING A horse farm is developing a new indoor arena in a rectangular building. They want the width of the building to be 3y feet and the length to be 4y+9 feet. Write an expression in simplest form to represent the area A of the building in terms of y.
A= ____
Answer:
3y(4y+9)=12y^2+27y......
The area A of the rectangular building in terms of y will be (12y² + 36y).
What is Area of rectangle?
The area of a rectangle is length time width.
Given that;
The width of rectangular building = 3y
The length of rectangular building = 4y + 9
Now,
Area of rectangle = length x width
Substitute all the values we get;
Area of a rectangle = 3y (4y + 9)
= 12y² + 36y
Thus, The area A of the rectangular building in terms of y will be
⇒ (12y² + 36y)

Answer:
Red: 144. Green: 360 Brown: 552. Yellow: 144.
Step-by-step explanation:
Okay, so, to find the probabilities of red and yellow, we gotta add green and brown probabilities and then subtract that from one. Green and brown probabilities added together are 0.76. Subtract that from one and you get 0.24. Divide that by two and we get 0.12 for both red and yellow. Now we multiply 1200 by each probability.
