Answers

The journal entry to record payroll expenses is ​Salaries and Wages Expense: $23,400 debit; Salaries and Wages Payable: $6,350 credit.

What is the journal entry?

In order to record the salaries and wages, the journal entry is to debit the Salaries and Wages Expense account. This is because money is leaving the company account.

The total deductions represent future payments. Thus it would be credited to the Salaries and Wages Payable account.

Answer:

13:192 in2

Step-by-step explanation

with the pythagoras theorem you can find the base =6

base x height /2= area =24

two triangles=24.2 =48

square one side =12

area=12.12=144

area of the shape = 144+48=192

Using the pythagorean theorem, we can calculate the base of the right triangle to be 6 (1 triangle)

-> The triangle's base length is 12.

So, the square's length is also 12.

We can now calculate the area of the figure : 12 x 12 + 12 x 8 : 2 = 192 in2

Answer:

y = -4x+7 is the equation simplified and answer choice A is the right answer.

Step-by-step explanation:

Your equation: y - 6 = -4(x+1)

Your Objective: You need to simplify the original equation and find another equation that is equivalent to the original equation.


Let's focus on the -4(x+1) side first.

This needs to have the distributive property applied.

Take -4 and multiply it by x and 1.

You should have -4x+1

Your equation now:

y - 6 = -4x+1

We want y to be by itself.

So add 6 to both sides.

y = -4x+1+6


Use PEMDAS

y = -4x+7

Each person pay $452.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A group of 12 friends bought a boat costing $5,424.

Now,

Since. A group of 12 friends bought a boat costing $5,424.

Hence, The cost of each person pay = $5,424 / 12

                                                         = $452

Thus, Each person pay $452.

Answers

Answer:

X = 8 And y = 1/5

Step-by-step explanation:

add equaction i and education ii,

2 -5y = 1

2x +5y = 17

------------------

2+2x = 18

or, 2x = 18 - 2

or X = 16/2

or X = 8

Again from equation i,

2 - 5y = 1

or, -5y = -1

or, y = -1/-5 (cut the subtraction sign)

or, y = 1/5

For the regression equation and e the number of kilowatt-hours, in thousands, for a six-room house  is mathematically given as

Y = 1.33-0.667X and  5.3332

What is the number of kilowatt-hours, in thousands, for a six-room house?

Generally, the equation for the  standard deviation  is mathematically given as

[tex]s[/tex]ₓ =[tex]\sqrt{\frac{\sum\(X-\=X)^2}{n-1} }[/tex]

= [tex]\sqrt{\frac{66.9}{10-1} }[/tex]

= 2.72

[tex]s_y[/tex] = [tex]\sqrt{\frac{36.4}{10-1} }[/tex]

= 2.01

therefore correlation coff

r = [tex]\frac{44.6}{(10-1)(2.72)(2.01)}[/tex]

r = 0.9038

In conclusion the regression equation is given

b = r_sy/sx

b = (0.9038)(2.01/2.72)

 = 0.667

intercept

a = 7.4-0.667(9.1)

a = 1.33

The regression equation is

Y = 1.33-0.667X

Y = 1.33-0.667X

Y = 1.33-0.667(6)

Determine a series of transformations that would map polygon ABCDE onto polygon A'B'C'D'E'?

Answers

Answer:

Dilate by a scale factor of 0.5 with the origin as the center of dilation.

Rotate 90° clockwise about the origin

Step-by-step explanation:

Polygon ABCD:

A = (-2, 4)B = (-8, 2)C = (-4, 8)D = (-2, 6)

Dilate by a scale factor of 0.5 with the origin as the center of dilation (pink polygon on attached diagram).

This means multiply the x and y values of the points by 0.5:

A → (-1, 2)

B → (-4, 1)

C → (-2, 4)

D → (-1, 3)

Rotate 90° clockwise about the origin: (x, y) → (-y, x)

A' = (-2, 1)

B' = (-1, 4)

C' = (-4, 2)

D' = (-3, 1)

So the transformations are:

Dilate by a scale factor of 0.5 with the origin as the center of dilation.Rotate 90° clockwise about the origin.

6. A festival is renting out booths to vendors for $55 for one day. There are 65 vendors and the festival occurs on Friday, Saturday, and Sunday. If the vendors participate on all the days, how much money will be collected by the festival from the vendors?

Answers

Answer: $10,725

Step-by-step explanation:

    First, we'll find the money for all the vendors on one day.

         65 * $55 = $3,575

   Next, Friday [1], Saturday [2], and Sunday [3] is three (3) days. We will multiply $3,575 by 3.

         $3,575 * 3 = $10,725

$10,725 will be collected from by the festival from the vendors.

The sets of numbers 3, 4, 5 and 8, 15, 17 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples! (5 points)

Answers

Pythagorean triples are 3 whole numbers which satisfy the Pythagorean theorem when they make up the sides of a right angled triangle.
For the numbers 3, 4 and 5, let 5 be the length of the hypotenuse (AC, of triangle ABC in which B is a right angle), and 4 and 3 be the lengths of the other 2 sides of the triangle (AB and AC).
According to the Pythagorean theorem,
=

25 = 9 + 16
25 = 25
Since 3, 4 and 5 satisfy the criteria, they are Pythagorean triples.
Similarly, for the numbers 8, 15 and 17, let 17 be the length of the hypotenuse (PR, of triangle PQR in which Q is a right angle), and 4 and 3 be the lengths of the other 2 sides of the triangle (PQ and QR).


289 = 225 + 64
289 = 289
Since 8, 15 and 17 satisfy the criteria, they are also Pythagorean triples.

3x + 3y = 18
5x + 3y = 28

Answers

Answer:

(5, 1 )

Step-by-step explanation:

3x + 3y = 18 → (1)

5x + 3y = 28 → (2)

subtract (1) from (2) term by term to eliminate y

(5x - 3x) + (3y - 3y) = 28 - 18

2x + 0 = 10

2x = 10 ( divide both sides by 2 )

x = 5

substitute x = 5 into either of the 2 equations and solve for y

substituting into (1)

3(5) + 3y = 18

15 + 3y = 18 ( subtract 15 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

solution is (5, 1 )

I need help please, You survey a random sample of 75 students at DPMS. Of those students, 30 said their favorite type of music is rap. Out of 1600 students at DPMS, predict the number of students whose favorite type of music is rap.

Answers

The predicted number of students is an illustration of ratios

Of the 1600 students, 640 are expected to have a rap as their favorite type of music

How to predict the number of students?

The given parameter can be represented using the following ratio:

Ratio = Rap : Total Students

So, we have:

30 : 75 = Rap : 1600

Express as fraction

30/75 = Rap/1600

Multiply both sides by 1600

Rap = 640

Hence, 640 of the 1600 students are expected to have a rap as their favorite type of music
