a. At the beginning of the year, Addison Company’s assets are $300,000 and its equity is $100,000. During the year, assets increase $80,000 and liabilities increase $50,000. What is the equity at year-end?
Equity at the end of the year = $130,000
Step-by-step explanation:
Step 1:
Given ,
Asset of the company at beginning of year = $300,000
Equity of the company at beginning of year = $100,000
Increase of the assets during the year = $80,000
Increase of the liabilities during the year = $50,000
We need to find the equity at the year end.
Step 2 :
The equity at any point can be obtained by using the formula
equity = assets - liability
At the beginning of the year ,
100,000 = 300,000 - liability
So liability = 300,000 - 100,000 = 200,000
Step 3 :
During the year, assets increase $80,000 and liabilities increase $50,000
So assets at the year end = 300,000 + 80,000 = $380,000
liabilities at the year end = 200,000 + 50,000 = $250,000
Therefore
Equity at the year end = 380,000 - 250,000 = $130,000
Step 4 :
Answer :
Equity at the year end = $130,000
A woman earns $ 1,350 in interest from two accounts in one year. If she has three times as much invested at 7% as she does at 6%, how much does she have in each account?
Answer:
The woman invested $15,000 at 7% interest rate and $5,000 at 6% interest rate.
Step-by-step explanation:
We are given the following in the question:
Let x be the interest earned from 7% interest rate and y be the interest earned from 6% interest rate.
The woman invested has three times as much invested at 7% as she does at 6%.
Thus, we can write the equation:
[tex]x = 3y[/tex]
The total interest is $1,350.
Thus, we can write the equation:
[tex]1350 = \dfrac{7x}{100} + \dfrac{6y}{100}\\\\7x + 6y = 135000[/tex]
Solving the two equations by substitution method:
[tex]7(3y) + 6y = 135000\\27y = 135000\\y = 5000\\x = 3(5000) = 15000[/tex]
Thus, she invested $15,000 at 7% interest rate and $5,000 at 6% interest rate.

2. Draw a right triangle with side lengths of 3, 4, and 5 units (cm or inches – your choice). Make sure to label all parts including side lengths, vertices, and the right angle. You may insert an actual picture of your drawing below or upload the picture in the Unit 2 TGA submission area.
Answer:
See the figure attached.Explanation:
In a right triangle the longest side is the hypotenuse. In this case the length is 5 units.
The hypotenuse is opposite to the right angle.
You must draw a small square inside the right angle. In the figure the right angle is labeled C.
The other two sides are the legs: in this case their lengths are 3units and 4 units.
The side with the shortest length is opposite to the smallest angle; the side with the intermediate length is opposite to the angle with the intermediate measure.
The vertices are marked with capital letters. I used A, B, and C.
With this explanation you can understand the figure attached and build one on your own.

How do i write the decimal of 214.013 in words?
two hundred fourteen and thirteen thousandths
Answer: two hundred fourteen and thirteen thousandths
Step-by-step explanation: If you wanted to do this with 214.013, I start with the whole number, which in this case is 214. To write 214 in words, that would be two hundred fourteen. Now, if you add the decimal, you know the first decimal spot is tenths, second is hundredths, and third is thousandths. The decimal would be thirteen thousandths. To add that up, you get two hundred fourteen and thirteen thousandths.

(a) How would you characterize the relationship between the hours spent on homework and the test scores (Positive or Negative, Linear or Non-Linear)? Explain.
(b) Paul used the function y= 8x + 40 to model the situation. What score does the model predict for 4 hours of homework?
(c) What does the number 40 in Part (b) mean in the context of the situation?
Please don’t answer if you are guessing. Answer if you really know the answer. And if you don’t understand the three questions, answer the ones you do know.
Answer:
a) Positive linear
b) 72
c) Marks scored when no time is spend on homework.
Step-by-step explanation:
a) relationship between the hours spent on homework and the test scores
As the time spent on homework increases the test score increases.
Similarly if less time is spent on homework, there would be a decrease in test score.
The two variables are directly related.
Thus, there relationship can be expressed as a positive linear relationship.
b) The model function
[tex]y= 8x + 40[/tex]
where y is the test score and x is the time spent on homework in hours.
Score predicted by model when x = 4
[tex]y(4)= 8(4) + 40 = 32 +40 = 72[/tex]
Thus, model predict that the score on test will be 72 when 4 hours are spent on homework.
c) Interpretation of 40
When x = 0
[tex]y(0)= 8(0) + 40 = 40[/tex]
Interpretation:
Thus, when Paul spends no time on homework that is zero hours are spend on homework, then, Paul will score 40 on test.
28913 To the nearest thousand
Answer:
29000
Step-by-step explanation:
Nearest thousand means the thousand at which the digit is nearest to. Now in approximation, we round up numbers from 1 to 4, to Zero while numbers from 5 to 9 are rounded up to 1.
28913 is between thousand 28,000 and 29000.
And then to be rounded up to the nearest thousand, the digit 9, before the thousand digit 8, in the number 28913 will therefore will rounded up to 1 and added to the thousand digit 28.
We therefore have 29,000

Vhich graph represents the function f(x) = x2 + 5?
Answer:
I would say Graph 2 because if its showing f(x)=x2+5
there are no negatives in this equation, so I think it is graph 2
The graph of the function is attached to the solution.
The given equation is f(x) = x²+5, the power on the variable is 2, that means the equation is a quadratic equation therefore, the graph will be a parabola,
Since, there is no negative sign so, the parabola will be opened up,
Also, there are 5 units added in the equation that mean the parabola will be 5 units up from the origin.
So, the graph will be an upward opened parabola with its vertex at (0, 5)

For a fund raising campaign, a club has a choice of buying products for $20 plus 50% of the sales or $100 plus 25% of the sales. For what level of sales would the club have to pay the same total with either deal
a: $3.20
b: $117
c: $320
d: $480
Answer:
C $320
Step-by-step explanation:
write equations for the two possible choices
situation 1:
y₁ = 20 + 0.5x, where y is the total price the club pays and x is the sales
** note i use 0.5 instead of 50, since 50 would represent 5000%
y₂ = 100 + 0.25x, where y is the total price the club pays and x is the sales
now set the two equations equal to each other
20 + 0.5x = 100 + 0.25x
isolate x by subtracting 0.25x and 20 from each side
20 + 0.5x - 0.25x - 20 = 100 + 0.25x -0.25x -20
0.25x = 80
divide both sides by 0.25
[tex]\frac{0.25x}{0.25}[/tex] = [tex]\frac{80}{0.25}[/tex]

What is the solution to this system of equations? 4x + 5y = 7 3x – 2y = –12What is the solution to this system of equations? 4x + 5y = 7 3x – 2y = –12
The solution of the system of equations is [tex]x=-2[/tex] and [tex]y=3[/tex]
Explanation:
The system of equations are [tex]4 x+5 y=7[/tex] and [tex]3 x-2 y=-12[/tex]
To determine the solution of the equation, let us solve the equations by elimination method.
Thus, multiplying the equation [tex]4 x+5 y=7[/tex] by 2, we get, [tex]8x+10y=14[/tex]
Multiplying the equation [tex]3 x-2 y=-12[/tex] by 5, we get, [tex]15x-10y=-60[/tex]
Adding these two equations, we have,
[tex]\ \ 8x+10y=14\\15x-10y=-60\\---------\\23x=-46[/tex]
Dividing both sides by 23, we have,
[tex]\frac{23x}{23} =\frac{46}{23}[/tex]
[tex]x=-2[/tex]
Thus, the value of x is [tex]x=-2[/tex]
Substituting [tex]x=-2[/tex] in the equation [tex]4 x+5 y=7[/tex], we get,
[tex]4 (-2)+5 y=7[/tex]
[tex]-8+5 y=7[/tex]
[tex]5y=15[/tex]
[tex]y=3[/tex]
Thus, the value of y is [tex]y=3[/tex]
Hence, the solution of the system of equations is [tex]x=-2[/tex] and [tex]y=3[/tex]
The solution to the system of equations, is: (-2, 3).
Solution to System of EquationsTo find the solution, you can use the elimination method by first making both equations equivalent. Then add or subtract to eliminate a variable.
Given:
4x + 5y = 7 --> Eqn. 13x – 2y = –12 --> Eqn. 2Multiply eqn. 1 by 3 and eqn. 2 by 4:
12x + 15y = 21 --> Eqn. 1
12x – 8y = –48 --> Eqn. 2
Subtract:23y = 69
Divide both sides by 23y = 3
Substitute y = 3 into eqn. 1.
4x + 5(3) = 7
4x + 15 = 7
4x = 7 - 15
4x = -8
x = -2

what is the focus of the parabola

enter your answer in the Box
I've seen so many wrong answers and I got it wrong on my quiz
answer: (-4,1)
Answer:
(-4,1)
Step-by-step explanation:
The given parabola is
[tex]y = - \frac{1}{4} {x}^{2} - 2x - 2[/tex]
When we rewrite in vertex form, we get;
[tex]y = - \frac{1}{4} {(x + 4)}^{2} + 2[/tex]
Or
[tex]{(x + 4)}^{2} = - 4( y - 2)[/tex]
When we compare to:
[tex]{(x - h)}^{2} = 4p( y - k)[/tex]
We have 4p=-4
This means p=-1
But the vertex is at:
(-4,2)
Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.
Hence the focus is (-4,1)

Eva is saving money for a trip. She is able to save $52 a week. Her friend from Japan, Ryu,is also saving money. Ryu is able to save 5500 yen(Japanese money) each week. If $4 is equal to about 440 yen, who is saving at a greater rate?
Answer:
Eva
Step-by-step explanation:
If 4 dollar = 440 yen
Therefore, 1 dollar = (440 ÷ 4) yen
1 dollar = 110 yen
As Eva is saving 52 dollars per week, and Ryu is saving 5,500 yen per week, we have to convert dollar into yen to find who has saved more.
1 dollar = 110 yen
52 dollar = (52 × 110) = 5720 yen
It means Eva is saving 52 dollar which is equivalent to 5,700 yens. It is more than Ryu's saving account.

Answer:
182.25 J
Step-by-step explanation:
KE = (0.5)*m*v^2
KE = (0.5)*(0.18 kg)*(45 m/s)^2
KE = 182.25 Joules
Hope this helps!
Final answer:
The kinetic energy of a 0.18 kg ball moving at 45 m/s is calculated using the formula KE = (1/2)mv² and is found to be 182.25 joules.
Explanation:
The kinetic energy (KE) of an object is calculated using the formula KE = (1/2)mv², where m is the mass of the object and v is its velocity. For a ball with a mass of 0.18 kg moving at a velocity of 45 m/s, we can find its kinetic energy by substituting these values into the formula.
KE = (1/2) imes 0.18 kg imes (45 m/s)²
= 0.09 kg imes 2025 (m/s)²
= 182.25 joules
Therefore, the kinetic energy of the ball is 182.25 joules.

Final answer:
A set of ordered pairs is called a relation. Relations include all possible mappings of pairs, while a function is a specific type of relation where each input is paired with only one output. The correct answer is option (D).
Explanation:
A set of ordered pairs is called a relation. For example, if we have two sets A and B represented by ordered pairs, the domain of set A would be the set of all the first elements, and the range of set A would be the set of all the second elements.
It's important to note that a function is a specific type of relation where each element of the domain is associated with a unique element of the range, which means that each input (or argument) is mapped to exactly one output (or value).
