what is a theory in science
A scientific theory is a validated explanation of some aspect of the natural world, based on multiple facts that have been frequently verified through research and experimentation. Fact theories are not "guesses" but reliable accounts of the real world.
There is a quadrilateral MNPQ in which side MN is congruent to side PQ and side NP is parallel to side MQ. The diagonal MP and the diagonal NQ intersect each other at point R. If MP = 6x − 5, QR = 3x + 1, and RN = 6, what is QN?
Answer: QN = 12
Step-by-step explanation: This quadrilateral is a paralelogram because its 2 opposite sides (NP and MQ) are parallel and the other 2 (MN and PQ) are congruent.
In paralelogram, diagonals bisect each other, which means QR = RN.
If QR = RN:
QR = 6
Then,
QN = QR + RN
QN = 6 + 6
QN = 12
The diagonal QN of quadrilateral MNPQ is QN = 12.
An amount of #550,000.00 was realised when a principal,x was saved 2% simple interest for 5 years. Find the value of x
Answer:
£500,000.00
Step-by-step explanation:
Principal = x
Saving rate = 2% PA simple
Time = 5 years
Final amount = £550,000
x*(1+ 2*5/100) = 550,000x*(1 + 0.1) = 550.0001.1x = 550,000x= 550,000/1.1x= 500,000Principal amount is £500,000
Answer:
[tex]\huge \boxed{{x=500,000}}[/tex]
Step-by-step explanation:
[tex]A=P(1+rt)[/tex]
[tex]A[/tex] = amount ⇒ 550000
[tex]P[/tex] = principal amount ⇒ x
[tex]r[/tex] = rate ⇒ 2%
[tex]t[/tex] = time ⇒ 5
[tex]\displaystyle 550000=x(1+\frac{2}{100} (5))[/tex]
Solve for the brackets.
[tex]\displaystyle 550000=\frac{11}{10}x[/tex]
Multiply both sides of the equation by [tex]\frac{10}{11}[/tex].
[tex]500000=x[/tex]
The value of x (principal amount) is 500,000.

What point would you have when (-7, 3) is reflected over the line y=x?
A. (3,-7)
B. (-3,7)
C. (7,-3)
D. (-7,3)
The point would you have when (-7, 3) is reflected over the line y=x is (7, -3).
The line y=x looks like an even, the diagonal line going through (0, 0) on a graph.
If you have (-7,3), you are in the first quadrant (in the upper left square of the graph).
What is the reflection?Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns to the medium from which it originated.
If you reflect it diagonally, the digits themselves would remain that same, but the value would flip (if it’s positive, it’ll become negative, if it’s negative, it’ll become positive).
So if we do that with (-7, 3), it becomes (7, -3).

In the figure below,m /_ 1=58º. Find m/_2
Answer:
32°
Step-by-step explanation:
What we have to notice here is that m∠1 and m∠2 are complementary angles. This means that their angles add up to 90°.
Since we know the measure of m∠1, we can easily find the measure of m∠2 since both add up to 90.
m∠1 is 58, so:
[tex]58 + x = 90[/tex]

Victoria searched her house for quarters. She started with 17 quarters and found 6 more quarters. She then goes to the arcade. If a game costs 2 quarters to play, how many games can she play and how many quarters are left over? Victoria can play times and there will be quarters left over.
Answer:
11 games
Step-by-step explanation:
17+6=23
23/2=11.5
Victoria can play 11 games. You'd usually round up, but in this case you can't play half a game so she'll play 11 games and have one quarter leftover.
Answer:
Victoria can play 11 games and have 1 quarter left over.
Step-by-step explanation:
17 given quarters +6 found quarters = 23 total quarters.
Since 23 is an odd number and we want to divide by 2, we have to go down to the last even number: 22. (This gives us the left over quarter)
22 quarters/2quarters per game = 11 games

Which equations have one solution
Answer: C and F
Step-by-step explanation:
Remember that for two equations to have the same solutions they need to have the different slopes and different y intercepts or they could have the same y-intercepts but different slopes.
First we will simply each of the equations
A. [tex]\frac{1}{3} x + 3 = 26 + \frac{6}{18}x - 23[/tex] reduces to .[tex]\frac{1}{3}x + 3 = \frac{1}{3} x + 3[/tex] Since this have the same slopes and same y-intercept they have infinitely many solutions
B. x +3 + 3x = -3 +4x +6 reduces to 4x + 3 = 4x +3 This also have the same slopes and same y-intercepts which means it also have infinitely many solutions.
C. 2(1/5 + 1/4x) -2x = x -1 reduces to -3/2x +2/5 = x -1 This have different slopes and different y intercepts so they have One solution.
D . 4.3x + 2.5 -2.2x + 2.2 -2.1x = 0 reduces to 4.7 = 0 which means that this equation have no solution because 4.7 does not equal 0.
E. 2(4x +3) + 2x= 5(2x + 3) reduces to 10x + 6 = 10x + 15 which means this also have No solution because they have the same slopes but different y-intercepts.
F. 2/5x + 10 + 3/5x = 2x + 5 reduces to 1x + 10 = 2x + 5 This also have 1 solution because they have different slopes and different y intercepts.

OmZW = 55°
mZZ = 125°
mZZ = 55°
PLEASE ANSWER FAST TIMED TEST
Answer:
m∠W = 125°
m∠X = 55°
m∠Z = 55°
Step-by-step explanation:
The explanation of angle measures is shown below:-
The shape which is parallelogram WXYZ. m∠Y = 125
A parallelogram represents the shape of quadrilateral in which both opposite sides and opposite angles are similar to each other. One parallelogram diagonals bisect each other. Consecutive angles are also supplementary to a parallelogram.
In WXYZ parallelogram is there
m∠Z + m∠Y = 180° is an angle of Consecutive in a parallelogram is supplementary
m ∠ Z + 125 = 180
m ∠ Z = 180 - 125
m ∠ Z = 55°
m ∠ W which equals to m∠Y where equal angles are Opposite
m∠W = 125°
m ∠ W + m ∠ X = 180°
which is the angle of Consecutive in a parallelogram called supplementary)
m ∠ X + 125 = 180
m ∠ X = 180 - 125
After solving the above equation we will get
m ∠ X = 55°

What is 50 percent of 62? 0.31 3.1 31 310
Answer:
[tex]\Huge \boxed{\mathrm{31}}[/tex]
Step-by-step explanation:
50 percent of 62 is also one half of 62.
62 × [tex]\frac{1}{2}[/tex] = 31
Answer:
50 is 31% of 62.
Step-by-step explanation:
To solve this, we need to set up our problem like this, since percentages are written with %, and add up to 100%.
[tex]\frac{62}{x} =\frac{100}{50}[/tex]
Next, we flip the denominators with the numerators so that the x ends up on the top.
[tex]\frac{x}{62}=\frac{50}{100}[/tex]
Finally, we can see that 50/100 is 1/2, so to solve x/62, we have to divide 62 by 2 to get our answer.
62 ÷ 2 = 31
Our answer is 31%.

Answer:
x = 12; m<ABC = 76
Step-by-step explanation:
The two angles whose measures are given form a linear pair. Therefore, they are supplementary angles, and their measures add up to 180 degrees.
8x - 20 + 116 - x = 180
7x + 96 = 180
7x = 84
x = 12
The angle with measure 8x - 20 and angle ABC are vertical angles. That means that their measures are equal.
m<ABC = 8x - 20 = 8(12) - 20 = 96 - 20 = 76
Answer: x = 12; m<ABC = 76
Dena bought 4 stuffed animals and 7 toy trains for $75. At the same prices, Nico bought 6 stuffed animals and 5 toy trains for $74. What is the price of a stuffed animal?
Answer:
$6.50
Step-by-step explanation:
Create a system of equations, where s represents the price of a stuffed animal and t represents the price of a toy train:
4s + 7t = 75
6s + 5t = 74
Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2:
12s + 21t = 225
-12s - 10t = -148
11t = 77
t = 7
Plug 7 in as t to find s:
4s + 7t = 75
4s + 7(7) = 75
4s + 49 = 75
4s = 26
s = 6.5
= $6.50 for a stuffed animal

Find the area of the triangle.
16 in.
25 in.
Answer:
The area of the triangle with the given measurements is 200 in²
Step-by-step explanation:
For this problem, we will need to know the formula for finding the area of a triangle.
A = 1/2(bh)
Now, let's plug in these numbers so we can find the area.
A = 1/2(bh)
A = 1/2(16*25)
A = 1/2(400)
A = 200 in.²
Find the component form of the vector that translates P(−3, 6)
to P′(−4, 8).
Answer:
Component form of the vector will be (-1, 2).
Step-by-step explanation:
When [tex]P(x_1, y_1)[/tex] translates to [tex]P'(x_2,y_2)[/tex] vector V formed after the translation will be,
V = [tex]<(x_2-x_1), (y_2-y_1)>[/tex]
If we draw this vector on a graph,
Vector will start from origin and the terminal point will be at [tex][(x_2-x_1), (y_2-y_1)][/tex]
Therefore, component form of the vector that translates from P(-3, 6) and P'(-4, 8) will be,
V = [tex]<(-4+3),(8-6)>[/tex]
V = [tex]<(-1,2)>[/tex]
Translation involves changing the position of a point
The vector that translates P to P' is [tex]\mathbf{ <-1,2>}[/tex]
The points are given as:
[tex]\mathbf{P = (-3,6)}[/tex]
[tex]\mathbf{P' = (-4,8)}[/tex]
The translation rule is calculated as:
[tex]\mathbf{(x,y) = P' - P}[/tex]
So, we have:
[tex]\mathbf{(x,y) = (-4,8) - (-3,6)}[/tex]
Combine
[tex]\mathbf{(x,y) = (-4+3,8-6)}[/tex]
[tex]\mathbf{(x,y) = (-1,2)}[/tex]
Express as vectors
[tex]\mathbf{<x,y> = <-1,2>}[/tex]
Hence, the vector that translates P to P' is [tex]\mathbf{ <-1,2>}[/tex]

What is the fractional equivalent of the repeating decimal 0.6 ?
Answer:
2/3
Step-by-step explanation:
We know that 0.6 is part of the 1/3 family.
1/3 would be equal to 0.333...
2/3 would be equal to 0.666...
3/3 would equal to 1
Alternatively, we know that anything out of 9 or 99 would be a repeating decimal. Simply take 6 and divide it by 9:
6/9 = 0.666
We can then simplify the fraction by dividing both top-bottom by 3:
6/9 = 2/3
