Step-by-step explanation:

Given the above parallelogram,

1) ∠ABC = 90°

2) ∠BCD = 90°
3) ∠CDA = 90°
4)  ∠DAB = 90°

To find the value of the angles, we need to first find x. Given that ∠ABC  = (x+35)° on the basis of opposite angles in a parallelogram, and

∠CDA = (180-(3x-75)°

since ∠ABC and ∠CDA  are opposite angles.

We can state that
(180-(3x-75)° = (x+35)°  since opposite sides of a parallelogram are equal.
Simplifying the above, we can find x:

180 - (3x - 75) = 180 - 3x + 75 = 255 - 3x

Now we can substitute this expression into the original equation:

255 - 3x = x + 35

To solve for x, we want to isolate the variable on one side of the equation. Let's start by adding 3x to both sides:

255 = 4x + 35

Next, we can subtract 35 from both sides:

220 = 4x

Finally, we can divide both sides by 4 to get the value of x:

x = 55

Therefore, the solution to the equation is x = 55°.

Since x = 55°

∠ABC  = (x+35)°

∠ABC = 55 + 35

∠ABC = 90°


Also, since:
∠CDA = (180-(3x-75)°)
∠CDA = 180- (165-75)

∠CDA = 90°

Since ∠DAB = (3x-75)° on the basis of alternate angles,
∠DAB = (3(55) -75)°

∠DAB  = 165 -75

∠DAB  = 90°


Since  ∠DAB is opposite ∠BCD and Opposite angles of a parallelogram are equal, thus, ∠BCD is also 90°

Given that two of the angles in this triangle are equal and have a measure of 78 degrees and sides 4x + 23, 10x-1 the solution x = -1.15 is a valid solution.

What is the inequality equation?

A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement. So, 4 is a solution for example 1, while 8 is not. The solution set of an inequality is the set of all solutions.

In a triangle, the sum of the measures of the angles is always 180 degrees. Since we are given that two of the angles in this triangle are equal and have a measure of 78 degrees each, the third angle must have a measure of:

180 - 78 - 78 = 24 degrees

Now we can use the Law of Cosines to set up an equation to solve for x. The Law of Cosines states that:

c² = a² + b² - 2abcos(C)

where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

We can choose any of the sides to be the side opposite the 24-degree angle, but let's use side 2, which has a length of 10x - 1. Then we have:

(10x - 1)² = (4x + 23)² + (side 3)² - 2(side 3)(4x + 23)cos(78)

Simplifying and solving for side 3, we get:

(side 3)² = (10x - 1)² - (4x + 23)² + 2(10x - 1)(4x + 23)cos(78)

(side 3)² = 36x² + 360x + 840

Taking the square root of both sides, we get:

side 3 = √(36x² + 360x + 840)

Now we can use the fact that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, we have:

side 1 + side 2 > side 3

4x + 23 + 10x - 1 > √(36x² + 360x + 840)

14x + 22 > √(36x² + 360x + 840)

Squaring both sides, we get:

196x² + 616x + 484 > 36x² + 360x + 840

Simplifying and rearranging, we get:

160x² + 256x - 356 < 0

We can solve this inequality using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = 160, b = 256, and c = -356.

Plugging in these values, we get:

x = (-256 ± √(256² - 4(160)(-356))) / 2(160)

x = (-256 ± √(124160)) / 320

x = (-256 ± 352) / 320

x = 0.30 or x = -1.15

However, we need to check that these values satisfy the inequality we found earlier:

14x + 22 > √(36x² + 360x + 840)

For x = 0.30, we get:

14(0.30) + 22 > √(36(0.30)² + 360(0.30) + 840)

25.2 > 25.2

This is not true, so x = 0.30 does not work.

For x = -1.15, we get:

14(-1.15) + 22 > √(36(-1.15)² + 360(-1.15) + 840)

3.3 > 3.3

This is true, so x = -1.15 is a valid solution.

Therefore, the solution x = -1.15 is a valid solution.

Answer:

Step-by-step explanation:

First, we need to simplify the expression inside the parentheses:

8 1/2 - 2 = 8 + 1/2 - 2 = 6 1/2

Next, we need to evaluate the exponent:

2^2 = 2 x 2 = 4

Now, we can substitute the simplified values into the expression:

7 1/4 x 4 + (6 1/2) ÷ 3

Next, we need to evaluate the multiplication and division from left to right:

7 1/4 x 4 = 29 + (6 1/2) ÷ 3

6 1/2 ÷ 3 = 2 1/6

Substituting the simplified value:

29 + 2 1/6

Next, we need to add the two values:

29 + 2 1/6 = 31 1/6

Therefore, the final answer is 31 1/6.

The car's value will decrease at rate of 1/5.

Rate refers to the ratio between two quantities with different units. For example, if you travel 100 miles in 2 hours, your rate of speed would be 50 miles per hour (mph).

From the graph, we have the following:

1: At mileage (x) = 20,000 miles, value of car (y) = $12000

2: At mileage (x) = 40,000 miles, value of car (y) = $8000

Rate = (y2 - y1)/(x2 - x1)

Rate = (8000 - 12000)/(40000 - 20000)

Rate = -1/5

The total amount that must be repaid is $139,076.12.

Annual simple interest is a type of interest that is calculated on the principal amount of a loan or investment for a one-year period. Simple interest is a fixed percentage of the principal amount, which is added to the principal at regular intervals. The interest is calculated only on the original principal amount and does not include any interest earned on the interest itself.

Compound interest is a type of interest that is calculated not only on the principal amount of a loan or investment, but also on the interest earned on that principal amount over time. In other words, compound interest is interest that is added to the principal amount, and then interest is calculated on the new total amount (principal + interest). This process is repeated at regular intervals, such as monthly or annually.

In the given question, The total amount that must be repaid can be found using the simple interest formula:

I = Prt

Where:

P = principal amount borrowed = $87,495

r = annual interest rate = 8.355%

t = time period in years = 7

So, substituting the values we get:

I = 87,495 * 0.08355 * 7 = 51,581.12

Therefore, the total amount that must be repaid is:

87,495 + 51,581.12 = 139,076.12

Rounding to the nearest cent, the answer is $139,076.12.

a. The owners' equity increased from $1,567 in 2014 to $3,122 in 2015.

b. The change in net working capital for 2015 is $168.

c. The amount of fixed assets did Weston Enterprises sold is $1630

d. Weston Enterprises must have paid off $2,253 in long-term debt during the year

Now, let's move on to the questions.

a. To find the owners' equity for 2014 and 2015, we need to subtract the total liabilities from the total assets. For 2014, the calculation would be,

Owners' equity 2014 = Total assets 2014 - Total liabilities 2014

Owners' equity 2014 = (Current assets 2014 + Net fixed assets 2014) - (Current liabilities 2014 + Long-term debt 2014)

Owners' equity 2014 = (964 + 4,384) - (401 + 2,380)

Owners' equity 2014 = $1,567

For 2015, the calculation would be:

Owners' equity 2015 = Total assets 2015 - Total liabilities 2015

Owners' equity 2015 = (Current assets 2015 + Net fixed assets 2015) - (Current liabilities 2015 + Long-term debt 2015)

Owners' equity 2015 = (1,176 + 5,104) - (445 + 2,713)

Owners' equity 2015 = $3,122

b. The change in net working capital for 2015 can be calculated by subtracting the net working capital for 2014 from the net working capital for 2015. Net working capital is the difference between current assets and current liabilities.

Net working capital 2014 = Current assets 2014 - Current liabilities 2014

Net working capital 2014 = 964 - 401

Net working capital 2014 = $563

Net working capital 2015 = Current assets 2015 - Current liabilities 2015

Net working capital 2015 = 1,176 - 445

Net working capital 2015 = $731

Change in net working capital = Net working capital 2015 - Net working capital 2014

Change in net working capital = 731 - 563

Change in net working capital = $168

c. To find out how much in fixed assets Weston Enterprises sold, we need to use the equation for the cash flow from assets,

Cash flow from assets = Cash flow to creditors + Cash flow to owners

Cash flow from assets = (Interest paid - Net new long-term debt) x (1 - Tax rate) + (Depreciation x Tax rate)

Cash flow from assets = (328 - (2,713 - 2,380)) x (1 - 0.4) + (1,190 x 0.4)

Cash flow from assets = (-$57) + $476

Cash flow from assets = $419

Net increase in fixed assets = Net fixed assets 2015 - Net fixed assets 2014

Net increase in fixed assets = 5,104 - 4,384

Net increase in fixed assets = $720

Amount of fixed assets sold = Net increase in fixed assets - New fixed assets purchased

Amount of fixed assets sold =  $2,350 - $720

Amount of fixed assets sold = $1,630

d. To calculate the amount of long-term debt paid off during the year, we need to use the equation for the cash flow to creditors,

Cash flow to creditors = Interest paid - Net new long-term debt

Cash flow to creditors = $328 - ($455 - $2,380)

Cash flow to creditors = $2,253

Step-by-step explanation:

The classification of the system of linear equations 4x + y = 4 and y = -4x + 4 is: consistent and independent. The Option B is correct.

We have a consistent independent equation when a system of linear equations has exactly one solution. When this occurs, the graphs of the system's lines cross at exactly one point.

For our question, we can start by rearranging the first equation to isolate y:

[tex]4x + y = 4\\y = -4x + 4[/tex]

We can see that the second equation is already in the form y = mx + b, where m is the slope and b is the y-intercept. So we can identify that the slope of the second equation is -4 and the y-intercept is 4.

Now we can compare the slopes and y-intercepts of the two equations to determine the classification of the system of equations:

In this case, we can see that the slopes of the two equations are different (-4 and 0) and the y-intercepts are the same (4). Therefore, the system is consistent and there is a unique solution. So the classification of the system of linear equations 4x + y = 4 and y = -4x + 4 is: consistent and independent

The density of the apple juice is approximately 1094 kg/m³.

Density is expressed mathematically as;

p = m / v

Where m is mass and v is volume.

Given that;

To calculate the density of the apple juice in kilograms per cubic metre (kg/m³), we need to convert the volume from cubic centimeters (cm³) to cubic meters (m³) and the mass from grams to kilograms.

1 cm³ = (1/100)^3 m³ = 10^-6 m³ (conversion factor from cm³ to m³)

1 g = (1/1000) kg (conversion factor from g to kg)

So, the volume of the apple juice in cubic meters is:

320 cm³ × (10^-6 m³/cm³) = 0.00032 m³

And the mass of the apple juice in kilograms is:

350 g × (1/1000) kg/g = 0.35 kg

Now, we can calculate the density using the above formula:

p = m / v

p = 0.35 kg / 0.00032 m³

p = 1093.75 kg/m³

p = 1094 kg/m³

Therefore, the density is 1094 kg/m³.

This equation tells us that the cost of x pounds of bananas is equal to the number of pounds of bananas, x, multiplied by the cost per pound

So equation becomes C = 0.70x

We can use proportional reasoning to set up an equation to represent the cost, C, of x pounds of bananas.

We know that 20 pounds of bananas cost 14, so the cost per pound can be found by dividing the total cost by the total weight:

Cost per pound = Total cost / Total weight

Cost per pound = 14 / 20 pounds

Cost per pound = 0.70 per pound

Now, we can use this cost per pound to set up an equation:

C = cost of x pounds of bananas

x = number of pounds of bananas

Cost per pound = 0.70

So, we can write the equation as:

C = 0.70x

  x = 30

Step-by-step explanation:

You want the measure of the acute angle where a tangent meets a chord that intercepts an arc of 300°.

An angle inscribed in a circle has half the measure of the arc it intercepts.

If one leg of that inscribed angle degenerates in length to zero, then the "inscribed" angle becomes the angle between the remaining chord and the tangent to one end of that chord.

In other words, the measure of the angle marked x° is half the measure of the arc it intercepts.

  x° = 1/2(360° -300°) = 1/2(60°)

  x° = 30°

The value of the variable x is 30.

To find out how much carpet Jacob needs to cover his living room, we can multiply the length and width of the room:

15 ft x 12 1/3 ft = 15 ft x (37/3) ft = 555/3 ft²

To simplify this fraction, we can divide both the numerator and denominator by 3:

555/3 ft² = 185 ft²

So the living room requires 185 square feet of carpet.

To find out how much carpet Jacob needs to cover his dining room, we can multiply the length and width of that room:

10 1/4 ft x 10 1/3 ft = (41/4) ft x (31/3) ft = 1271/12 ft²

To simplify this fraction, we can divide both the numerator and denominator by 1:

1271/12 ft² = 105.92 ft² (rounded to two decimal places)

So the dining room requires 105.92 square feet of carpet.

To find out how much carpet Jacob needs in total, we can add the amount of carpet required for each room:

185 ft² + 105.92 ft² = 290.92 ft²
