APUQ = ASUR, which proves that the two triangles are congruent.

To prove that APUQ = ASUR, we can use the concept of parallel lines and corresponding angles.

Since PQ || RS and PQ = RS, we can conclude that corresponding angles are equal.

In the figure, angle APU and angle ASR are corresponding angles and are therefore equal.

Also, angle UQP and angle USR are corresponding angles and are therefore equal.

Since the angles APU and UQP add up to 180 degrees (because they form a straight line), we can conclude that angle APU = 180 - UQP.

Similarly, angle ASR = 180 - USR.

Therefore, APU + UQP = ASR + USR

So, APUQ = ASUR, which proves that the two triangles are congruent.

The solution for f the angle ∠DEF will be 122°.

Geometry is the study of two- and three-dimensional figures such as quadrilaterals, triangles, circles, their sides, and angles.

Symmetry is defined as if the object is cut by its centre line the two cut parts should be the mirror image of each other so that we can call them symmetric to each other.

Given that the angles are:-

∠DCE = (3x + 16)°

∠DEF = (6x - 10)°

∠CDE = (2x - 4)°

In the triangle ΔCDE,

∠DEC = 180 - 3x - 16 - 2x + 4

∠DEC = (-5x + 168)°

∠DEC  + ∠DEF = 180

5x + 168 + 6x - 10 = 180

x = 180 - 158

x = 22

The property that should be used to continue simplifying the above equation is A-^1A = 1. So, correct option is C.

We can start with the equation AB = AC and multiply both sides by A^-1 on the left:

A^-1(AB) = A^-1(AC)

Using the associative property of matrix multiplication, we can simplify the left-hand side:

(A^-1A)B = (A^-1A)C

Using the fact that A^-1A = I (the identity matrix), we get:

IB = IC

Simplifying further using the fact that I times any matrix is that matrix itself, we obtain:

B = C

Therefore, the equivalent equation to AB = AC using A^-1 that simplifies to B = C is A^-1(AB) = A^-1(AC), and the property used to continue simplifying the equation is A^-1A = I.

The correct option is (C) A^-1A = 1, which is equivalent to A^-1A = I, since the identity matrix is denoted as 1 in some contexts.

Step-by-step explanation:

the points on the graph are scattered and have no correlation whereas the others all remain in a relatively similar shape

Answer:

178ft

Step-by-step explanation:

Split the shape up into pieces.  If you make an invisible cut vertically from the 14 ft length you will realise you have a small triangle attached to a rectangle.

You can assume that the height of the triangle is equal to the 20 - 14 as the left side must equal the right side for this shape thus this invisible length is equal to 6 ft

Area of triangle: (6ft x 6ft)/2 = 18 ft^2

Area of rectangle: 20ft x 8ft = 160 ft^2

Area of total shape = 160 + 18 =  178ft

So you're correct

Answer: The coordinates where the two lines intersect are (-5, -8).

Step-by-step explanation:
To find the coordinates where the two lines intersect, we need to solve the system of equations simultaneously. We can do this by substitution or elimination, but we'll use substitution here:

First, we set the two equations equal to each other:

x - 3 = 2x + 2

Next, we solve for x:

x - 2x = 2 + 3

-x = 5

x = -5

Now that we have the value of x, we can substitute it into one of the original equations to find the corresponding value of y. Let's use the first equation:

y = x - 3

y = (-5) - 3

y = -8

80 times, the house should be cleaned to buy the car.

Equation for the amount is y = 50t + 500

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

Given,

Amount in the savings = $500

Amount to get the car = $4500

Grandma pays $50 for every time after cleaning

then, after t times, the amount will be

y = 50 t + 500

here, y is the total amount after working

t is number of times of cleaning the house

For $4500

4500 = 50t + 500

50t = 4500 - 500

50t = 4000

t = 4000/50

t = 80

Hence, we have to clean the house 80 times to have $4500.

Step-by-step explanation:

Rounding to the nearest whole number, we get that the score a student would need to have a 30th percentile score on the SAT is 1345.  Correct option is B.

To find the score corresponding to the 30th percentile, we need to use the standard normal distribution with a mean of 0 and a standard deviation of 1. We can convert the SAT score to a standard normal score using the formula:

z = (x - μ) / σ

where x is the SAT score, μ is the mean score (1509), and σ is the standard deviation (312).

To find the score corresponding to the 30th percentile, we need to find the z-score that has an area of 0.30 to its left. Using a standard normal table or calculator, we can find that the z-score corresponding to a 30th percentile is approximately -0.52.

Now we can use the formula to find the corresponding SAT score:

-0.52 = (x - 1509) / 312

Solving for x, we get:

x = -0.52 * 312 + 1509 = 1345.36

Therefore, the answer is (b) 1345.

Answer: 6 and 1/3

Step-by-step explanation:

Assuming that sweet generous little Marcus here wants some muffins too, he has to share 19 blueberry muffins between 3 people (Marcus + friend 1 + friend 2.)

Most unfortunately, 19 isn't divisible by 3 to create a whole number (ie. a whole muffin).

Therefore you have 2 options:

Option 1:

19/3 = 6.333....

This means that each person will get 6 and 1/3 of a muffin

Option 2:

19/3 = 6 (and 1 remainder)

This means that each person will get 6 muffins each, but there will be a leftover muffin to feed the birds or something.

In the JK Flip-Flop truth table, when both inputs of the JK Flip-Flop are set to 1 and the clock input is also set to "High," the circuit is toggled from the SET to the RESET state.

Similar in operation to the SR flip flop is the JK flip flop. The JK flip flop is marked with the letters "J" and "K" rather than "S" and "R." When both inputs are set to 1, SR flip flips yield incorrect states as outputs, while JK flip flops do not, even when both "J" and "K" flip flops are set to 1. The only distinction between JK and SR flip flops is this. The JK Flip Flop is an additional clock input circuitry-equipped gated SR flip-flop. The presence of a clock input circuit prevents the invalid or unlawful output situation from occurring when both inputs are set to 1. The JK flip-flop hence has four input combinations that are possible: 1, 0, "no change," "toggle," and With the exception of the clock input, the JK flip flop's symbol is identical to that of the SR bistable latch.

The factorization of 2x² - 2x - 3x + 9 using the box method is (2x - 3)(x - 3).

To factor the trinomial 2x² - 2x - 3x + 9 using the box method, we first draw a box and divide it into four sections:

   | 2x  -3 |

   |--------|

   | -2x  9 |

Then, we fill in the top left section with the coefficient of the leading term, 2x, and the bottom right section with the constant term, 9.

   | 2x  -3 |

   |--------|

   | -2x  9 |

Next, we find two numbers that multiply to 2x * 9 = 18 and add to the coefficient of the middle term, -2x - 3x = -5x.

One way to do this is to factor out 2 from the leading two terms, giving 2x² - 2x - 3x + 9 = 2x(x - 1) - 3(x - 3), and then finding the product of (x - 1) and (x - 3) using the AC method:

AC method:

2x(x - 1) - 3(x - 3) = 2x(x - 1) - 3x + 9 - 3(-1)

We can then place these two numbers in the remaining two sections of the box:

   | 2x  -3 |

   |--------|

   | -2x  9 |

   | 2x  -3 |

   |--------|

   | -2x  9 |

   |--------|

   | -3   1 |

We can now factor the trinomial by taking the common factor out of each row and column of the box:

2x(x - 1) - 3x + 9 - 3(-1)

= (2x - 3)(x - 3)

Therefore, the factorization of 2x² - 2x - 3x + 9 using the box method is (2x - 3)(x - 3).
