Answer: Reflection.

Step-by-step explanation:

In the image, we can see that the right angles share a common side. In this common side, we can see that the right angles of the triangles are next to each other (because we have a straight line cut by a perpendicular one) and the same case for the top angle.

Then if we do a reflection over this common line of one of the triangles, the result will be the other triangle.

Then the correct option is a reflection

The rigid motion that verifies the triangles are congruent by SAS is reflection.

The angle of reflection simply means the angle that's formed between the normal ray and the reflected ray. It's the line that's perpendicular to the resulting surface at the point of incidence.

According to the law of reflection, the angle of reflection must be equal to the angle of incidence. Therefore, the rigid motion that verifies the triangles are congruent by SAS is reflection.

Answer:

a) The DSO decreases.

Step-by-step explanation:

DSO is short for Days Sales Outstanding and it is a measure of how quickly a company can convert its accounts receivable to cash. A company is described as strong when it has enough cash flow and this can be achieved by reducing the length of days within which accounts receivable can be converted to cash.

For the company to achieve a lowered DSO, it must ensure that customers with bad or low credit ratings are not allowed, or reasonably reduced in the business. The accounting and payment procedures must also be checked to be expedient so that delays in payment procedures would be reasonably reduced.

Answer:

  d, e

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a^-b = 1/a^b

__

In this case, it means the product is ...

  (6^1)(6^0)(6^-3) = 6^(1+0-3) = 6^-2 = 1/6^2 = 1/36

__

The 6 without an exponent is equivalent to 6^1, an exponent of 1.

The sum of the exponents is -2.

Add the exponents to simplify the expression.

The value of the expression is 1/36.

An equivalent is any expression that results in 6^-2. One such is (6^5)(6^-7).

Only the last two choices, d and e, apply.

Answer:

the loss per part was - $31

Step-by-step explanation:

If the total of losses was $2480 for 80 identical parts, then the loss per part is the division of $2480 by 80:

$2480/80 = $31

So the loss per each part was $31

which normally will be given with a negative sign in front indicating loss:

- $31

Answer:

x=1/2     y=1/4

Step-by-step explanation:

Get simplify the first equation to get x alone

4y/2=2x/2

2y=x

Plug x into the second equation

2(2y)+y=(2y)/2 +1

4y+y=y+1

4y+y-y=y-y+1

4y=1

y=1/4

Now plug the y-value into one of the equations and solve for x

4(1/4)=2x

2x=1

x=1/2

Check by plugging both the x- and y-values into the other equation and solving to make sure both sides are equal

2(1/2)+(1/4)=(1/2)/2 +1

1+1/4=1/4+1

5/4=5/4

The values are correct!

Answer:

Domain: [- ∞, 4.5],

Range: [0.5, ∞]

Step-by-step explanation:

One approach is a graphical representation to solving the problem, which you can see as the two attachment's below. Clearly the domain would be on the interval [- ∞, 4.5] and the range would be on the interval [0.5, ∞]. There is another approach to this though,

We can determine the domain by finding what value for p makes the function undefined

Given : h(p) = (p + 3) / (2p - 9),

Value for p where denominator = 0 :

2p - 9 = 0,

2p = 9,

p = 9 / 2 = 4.5

And to determine the range we have to determine the set of values that corresponds with the domain. In this case it's p = 0.5.

Answer:

∠POA= ∠POB = 50°

Step-by-step explanation:

The diagram of the given question has been drawn in the attachment.

From the diagram

Δ PAO  is congruent to Δ PBO.

as PO is common in Δ

∠ PAO = ∠PBO = 90°

PA =PB [ tangent from an external point]

⇒∠POA= ∠POB

Also, ∠APB+ ∠AOB = 180°

⇒ 80° + ∠AOB = 180°

⇒∠AOB = 100°

⇒ ∠POA= ∠POB = 50°

Solution:

Given,

Volume of the-

First cube box=1728 in³

Second cube box=13824in³

We know that volume of cube =a³

So for the first box

a³= 1728 in³

a= 12 in

Now, surface area of the first box

6a²= 6×(12)²

= 864 in²

and for the second box

b³= 13824 in³

b= 24 in

Now, the surface area of the second box

6b²= 6×(24)²

= 3456 in²

Now, the ratio of the surface area of first box to the second box will be

864:3456

=1:4

The surface area of the larger of two boxes is

3456 in²

Answer:

at ∠A     sin Ф = 180 + (2 / [tex]\sqrt{22}[/tex] )

at ∠B     cos Ф = 180 + (3[tex]\sqrt{2}[/tex]  / [tex]\sqrt{22}[/tex] )

at ∠C     tan Ф = 180 + (2 / 3[tex]\sqrt{2}[/tex]  )

Step-by-step explanation:

let (a) = 3[tex]\sqrt{2}[/tex]

let (b) = 2

let (c) = r

to get the value of hypotenuse (r) use pythagorean theorem

a² + b² = c²

2² + (3[tex]\sqrt{2}[/tex] )² = c²

c = [tex]\sqrt{22}[/tex]

use the law of sines to get the value of angle A (point origin)

sin Ф = opp / hyp

cos Ф = adj / hyp

tan Ф = opp / adj

at ∠A

sin Ф = 180 + (2 / [tex]\sqrt{22}[/tex] )

at ∠B

cos Ф = 180 + (3[tex]\sqrt{2}[/tex]  / [tex]\sqrt{22}[/tex] )

at ∠C

tan Ф = 180 + (2 / 3[tex]\sqrt{2}[/tex]  )

Answer:

(B) 0.708

Step-by-step explanation:

The table, representing details of this information and all that are necessary to calculate the linear correlation coefficient r, has been attached to this response.

With all details well represented on the table, we can now find the linear correlation coefficient r using the relation attached to this response:

From the relation;

n = sample size = 8

∑xy = 3347

∑x = 44

∑y = 569

∑x² = 320

∑y² = 41681

Substitute these values into the relation as follows;

[tex]r = \frac{3347 - \frac{44* 569}{8} }{\sqrt{(320 - \frac{44^2}{8} )(41681 - \frac{569^2}{8} ) } }[/tex]

[tex]r = \frac{217.50}{307.32}\\[/tex]

r = 0.7077

r = 0.708 to 3 decimal places

Therefore, the value of the linear correlation coefficient is 0.708

Answer:

60 ; 5220

Step-by-step explanation:

A) From the horizontal bar chart provided, it could be inferred that 85 people spell the word 'weird' correctly. The graph is scaled on a fixed interval of 10. Hence, the midpoint of 10 = 5

(80 + 5) = 85

B) In a group consisting of 8719 randomly selected people estimate how many more people can correctly spell weird than inoculate

From the graph :

85 per 100 could spell weird correctly while,

About 25 per 100 could spell inoculate correctly.

Difference In number per 100 people

(85 - 25) = 60 people per 100

We could round 8719 to the nearest 100 = 8700

Number of 100's in 8700 = 8700/100 = 87

(87 × 60) = 5,220 people

Answer:

y = -2/3x + 22/3

Step-by-step explanation:

An equation is written in slope-intercept form when it is written as:

y = mx + b, where m is the slope of the line and b is the y-intercept.

Therefore, because we are given m and a coordinate pair of the line, we can use the point-slope formula to make the equation.

The point-slope formula is [tex]\boxed{y-y_{1}=m(x-x_{1})}[/tex].

Because we are given only one coordinate pair, it is labeled as [tex](x_{1}, y_{1})[/tex].

Now, just plug in this information and solve the equation.

y - 4 = -2/3(x - 5) Distribute the -2/3 throughout the terms.

y - 4 = -2/3x + 10/3 Add 4 to both sides of the equation.

y = -2/3x + 22/3

Answer:  15  dimes

Step-by-step explanation:

Nickels are 5 cents and dimes are 10 cents  and since they are a total of 1.95 coins in total we can set up the two equations and solve for how much there are for each of the money.

x + y = 24  

0.05x + 0.10y = 1.95   so solve for  y  and  x is the number of nickels while y is the number of dimes.

x+y=24

   -y    -y

x = -1y +24  

0.05(-1y +24) + 0.10y = 1.95

 -0.05y + 1.2 + 0.10y = 1.95

       0.05y + 1.2 = 1.95

                     -1.2   -1.2

          0.05y = 0.75

   y = 15

Answer: probability sampling

Step-by-step explanation:

Probability sampling is used as a sampling method in which the researcher chooses samples from a large population using a method which is based on the theory of probability. For an item to be qualify as a probability sample, that item must be selected using a random selection. An example is the selection of 2 girls from a group of 20 students where 12 are girls and 8 are boys.

Answer:

The divison would be:

My two yonger siblings: P3000 Each

Me: P4000.

This idea came about due to the fact that, the eldest an the youngest siblings are not meant to receive equal amount of anything when it is shared among them.

Step-by-step explanation:

This is the only logical way in which the P10,000 can be shared between me and my younger siblings in-order to obtain a whole pesos division and with no fractions. Anything aside this, would give room to involve spare change.

The amount each person gets from P10,000 in whole pesos and with no spare change is P4,000, P,3000 and P3,000 respectively.

Total amount given as allowance = P10,000

Number of people to share it = 3

1 older and 2 younger siblings

Let

the older sibling get P4,000

Each younger sibling gets P3,000

Each person gets a whole value of pesos without a remainder in the total allowance given.

Therefore, the amount each person gets from P10,000 is P4,000, P,3000 and P3,000
