100 POINTS HELP IM ALMOST DONE If a business uses a monthly accounting period, how often would it prepare a post closing trial balance?
A. yearly
B. weekly
C. monthly
D. daily

Answer:

To convert the weight from pounds to tons, we can divide the weight by 2,000, since there are 2,000 pounds in a ton.

3.9 million pounds / 2,000 = 1,950 tons

So, a fully loaded and fueled spacecraft that weighs close to 3.9 million pounds can be said to weigh 1,950 tons.

Answer:

[tex]\frac{2}{3}[/tex]

Step by Step Explanation:

Convert any mixed numbers to fractions.

Reduce fractions where possible.

Then your initial equation becomes:

[tex]\frac{143}{120}[/tex] - [tex]\frac{21}{40}[/tex]

Applying the fractions formula for subtraction,

= (140 × 40) - (21 × 120)

          120 × 40

= [tex]\frac{5720 - 2520}{4800}[/tex]

= [tex]\frac{3200}{4800}[/tex]

Simplifying [tex]\frac{3200}{4800}[/tex], the answer is [tex]\frac{2}{3}[/tex].

The expressions are solved and answered below.

The positive number we're looking for is 5/16.

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. For instance, the equation 6x + 5 = 20 consists of the two equations 6x + 5 and 20, which are separated by the 'equal' sign.

A mathematical statement that claims the equivalence of two expressions is known as an equation.

Let's call the positive number we're looking for x.

Then, the problem can be expressed as two equations:

12x² = 4x + 5x² = (4/12) x + (5/12)

x² = (1/3) x + (5/12)

x² - (1/3) x = (5/12)

(4/3) x = (5/12)

x = (5/12) × (3/4)

x = 5/16

Hence, the positive number we're looking for is 5/16.

Step-by-step explanation:

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Answer:

9800

Step-by-step explanation:

The median number is the middle term (or the average of the two middle terms, if there are an even number of terms) when sorted in an ascending order.

Sorting in ascending order:

8900, 9600, 9800, 12000, 15500

Hence, 9800 is the mean.

The rate of change over the interval 15 ≤ x ≤ 18 is equal to 2/3 or 0.67.

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function y(x) over the interval [15, 18]:

a = 15; g(a) = 3

b = 18; g(b) = 5

Substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (5 - 3)/(18 - 15)

Average rate of change = 2/3

Average rate of change = 2/3 or 0.67.

Using proportional relationships, it is found that:

1. A = 15.8, B = 5, C = 63.2.

2. A table with a rate of 0.82 represents the data.

3. Candidate B received 54 votes.

A direct proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality k, also called unit rate, as follows:

y = kx

here, we have,

For item 1, the constant is given as follows:

k = 31.6/4 = 7.9.

Hence the equation is:

y = 7.9x.

Then the value of A is found as follows:

A = 7.9(2)

= 15.8.

The value of B is found as follows:

7.9B = 39.5

B = 39.5/7.9

B = 5.

The value of C is:

C = 7.9(8) = 63.2.

For item 2, the rate is given as follows:

k = 35/42.5 = 0.82.

Hence a table with a rate of 0.82 represents the data.

For item 3, we have that the relation is:

B = kA.

Hence the constant is:

k = 18/15

k = 1.2.

Then the number of votes received by Candidate B is:

B = 1.2 x 45 = 54 votes.

Answer:

I think the coefficient is 1/3.

Because (x, y) to (1/3x, 1/3y)

The value of a must be equal to (k + 2), and then the equation is only true if k = 6, then a = 8.

We want the equation:

(k + 2)x + 3k = ax + 18

To be true for all values of x, then we must have the same thing in both sides of our equation.

Now we wod want the dependence on x to dissapear, then:

(k + 2)x = ax

(k + 2) = a

That must be value of a, and then the equation becomes:

k*x + 2x + 3k = (k+ 2)x + 18

3k = 18

This is only true if k = 6, then:

k + 2 = a

6 + 2 = a

a = 8

That must the value of a.

Prove of that if the lengths of two sides of a triangle are a and b, respectively, then the lengths of the corresponding altitudes to those sides are in the ratio b.

A triangle is a three by three-sided polygon having three angles and three sides. It is one of the most fundamental and basic shapes in geometry and is used in many other fields of physical science. Triangles are also utilized in architecture and other areas of design and come in a variety of shapes.

Let, a triangle Δ ABC be given, and let its sides be BC = a and AC = b

(figure is given below)

Let, AM and BN are altitudes of corresponding sides of traingle Δ ABC.

We know that the altitude of a triangle is the perpendicular drawn from the vertex of the triangle to the opposite side.

Notice two right-triangles triangles Δ AMC and Δ BNC

We can conclude that the pairs of congruent angles are:

Δ AMC ≅ Δ BNC ≅ 90°

∠ACM ≅ ∠BCN          (common angle)

So, Δ AMC ≈ Δ BNC by the Angle-Angle Similarity Theorem

The triangles are similar and therefore their corresponding angles are congruent:

AM/BN = AC /BC = a/b

(b) The future value of $900 saved each year for 10 years at 8 percent is $13037.91.

(c) The amount a person would have to deposit today (present value) at an interest rate of 6 percent to have $1,000 five years from now is $747.26.

(d) The amount a person would have to deposit today to be able to take out $600 a year for 10 years from an account earning 8 percent is $8691.93.

What in annuity?

An annuity is a contract that you have with an insurance provider that calls for regular payments to be made by the insurer to you, either now or in the future.

(a) The future value of $450 six years from now at 7 percent.

FV= PV × (1 + r)n

FV= $450 × (1 + 7%)6

FV= $450 × (1.07)6

FV= $450 × 1.50073

FV= $675.33

(b) The future value of $900 saved each year for 10 years at 8 percent.

This is annuity as $900 is saved each year

Formula :: FV = PMT * (((1 + r%)n - 1) / r%)

FV = $900 × (((1 + 8%)10 - 1) / 8%)

FV= $900 × 14.4865624

FV= $13037.91

(c) The amount a person would have to deposit today (present value) at a 6 percent interest rate to have $1,000 five years from now.

PV= FV / (1 + r)n

PV= $1000 / (1 + 6%)5

PV= $1000 / 1.3382255

PV=$747.26

(d) The amount a person would have to deposit today to be able to take out $600 a year for 10 years from an account earning 8 percent.

Annuity value = $600

FV= Annuity value × Annuity factor(10%,8 year)

= $600 × (((1 + 8%)10 - 1) / 8%)

= $600 × 14.4865624

= $8691.93

Answer:

Step-by-step explanation:

The degree of a polynomial in two or more variables is the highest of the sum of the degrees of each variable

Here there is only one term with variables x and y: xy²

Degree of x = 1, degree of y = 2

Sum of the individual degrees = 1 + 2 = 3

Answer:

Slope-intercept form: y=3/4x+3

Slope:3/4

y-intercept: (0,3)

Slope of line perpendicular: -4/3

Slope of line parallel: 3/4

Hope this helps!!

y=3/4x+3

the slope for the line perpendicular is the inverse negative slope which would be -4/3x

put in the original slope for the slope and the y-i is (0,3)

any line with the same slope would be parallel (i.e 3/4)

The coordinates of point c on the coordinate plane are (4, 1)

From the question, we have the following parameters that can be used in our computation:

B = (10, 7)

M = (7, 4)

The midpoint formula for two points (x1, y1) and (x2, y2) is:

(x1 + x2) / 2 = x_midpoint

(y1 + y2) / 2 = y_midpoint

So, for points B and C, we have:

x_midpoint = 7

y_midpoint = 4

Also, we have

x_B = 10

y_B = 7

The coordinates of C are calculated as

x_C = 2 * x_midpoint - x_B = 2 * 7 - 10 = 4

y_C = 2 * y_midpoint - y_B = 2 * 4 - 7 = 1

Answer:

No solution.

Step-by-step explanation:

First, we can simplify both sides of the equation by squaring them. This gives:

(√x+12)² = (√x + 2)²

Expanding both sides, we get:

x + 24√x + 144 = x + 4√x + 4

Moving all the terms to one side, we get:

20√x + 140 = 0

Subtracting 140 from both sides, we get:

20√x = -140

Dividing both sides by 20, we get:

√x = -7

However, this is not a valid solution for x, since the square root of a number cannot be negative. Therefore, there is no solution for x that satisfies the given equation.
