Final answer:
After making her online payments totaling $792.01, Kwei-Twang Kuo will have a balance of $24.82 in her checking account.
Explanation:
First, we'll calculate the total payments Kwei-Twang Kuo needs to make by adding up all of her expenses:
Store charge account: $160
Charitable donation: $40
Rent: $550
Cable bill: $42.01
Adding these amounts together gives us a total of $792.01 for the payments.
Let's calculate the balance of her checking account after she transfers $800 and makes the payments:
Begin with checking account balance: $16.83
Transfer into checking account: +$800.00
New balance before payments: $816.83
Total payments to be made: -$792.01
Final checking account balance: $24.82
Therefore, after Kwei-Twang Kuo makes her online payments, she will have a balance of $24.82 in her checking account.

Janelle has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 7mph and walks back at a speed of 3mph how long should she plan to spend walking back?
Final answer:
Janelle should plan to spend 3 hours walking back.
Explanation:
To find out how long Janelle should plan to spend walking back, we need to calculate the total time it takes her to run and walk. Since she runs at a speed of 7mph, she completes the distance of the race in 1 hour (4 miles / 7mph = 0.57 hours = 1 hour). Therefore, she spends 1 hour running and 3 hours left for walking. To find out the distance she walks back, we use the formula distance = speed x time. Since she walks at a speed of 3mph, the distance she walks back is 3mph x 3 hours = 9 miles.

Step-by-step explanation:
Peter wants to borrow $3,000. He has two payment plans to choose from. Plan A is 4% interest over 6 years. Plan B is 5% interest over 4 years. Using the formula mc024-1.jpg for payment, m, which statement best compares the plans?
Plan A has a monthly payment of about $23 less and a total interest charge of $120 less than plan B.
Plan A has a monthly payment of about $23 less and a total interest charge of $120 more than plan B.
Plan A has a monthly payment of about $23 more and a total interest charge of $120 more than plan B.
Plan A has a monthly payment of about $23 more and a total interest charge of $120 less than plan B
To determine which payment plan is better for borrowing $3,000, Plan A or Plan B, one must calculate both the monthly payments and total interest charges using the given annual interest rates and compounding periods for each plan and compare the results accordingly.
Peter wants to borrow $3,000 and is considering two different payment plans. To compare these plans, we need to calculate the monthly payment and total interest charge for each.
Plan A has an annual interest rate of 4%, compounded monthly over 6 years (or 72 months). Using the formula for monthly payment (m), we can find the monthly payment for Plan A:
m = P[r(1+r)^n] / [(1+r)^n-1]
Where:
Similarly, Plan B has an annual interest rate of 5%, compounded monthly over 4 years (or 48 months). We use the same formula to calculate the monthly payment for Plan B.
After calculating m for both plans, we can also calculate the total interest paid by multiplying the monthly payment by the number of payments and subtracting the principal amount from the result for each plan. Then, we can compare the monthly payments and total interest charges between Plan A and Plan B.

In the circle graph above, you can see that 47% of the company's monthly income is used to pay the owner's personal salary. If the amount of the owners's personal salary was $2,176.10 this month, what was the company's total monthly income this month?
Final answer:
To find the total monthly income, set up a proportion using the percentage of the owner's salary with the given amount. Solve for the total income to find the answer.
Explanation:
In the circle graph above, the owner's personal salary represents 47% of the company's monthly income. This means that $2,176.10 is 47% of the total monthly income. To find the total income, you can set up a proportion: $2,176.10 is to 47% as X is to 100%. Solving this equation gives you the company's total monthly income as $4,635.

Given the equation −4 Square root of x minus 3= 12, solve for x and identify if it is an extraneous solution
Answer:
[tex]x=\frac{225}{16}[/tex] is an extraneous solution.
Step-by-step explanation:
Given : Equation [tex]-4\sqrt x-3=12[/tex]
To find : Solve for x and identify if it is an extraneous solution?
Solution :
Step 1 - Write the equation,
[tex]-4\sqrt x-3=12[/tex]
Step 2 - Add 3 both sides,
[tex]-4\sqrt x-3+3=12+3[/tex]
[tex]-4\sqrt x=15[/tex]
Step 3 - Squaring both sides,
[tex](-4\sqrt x)^2=(15)^2[/tex]
[tex]16x=225[/tex]
Step 4 - Divide both side by 16,
[tex]\frac{16}{16}x=\frac{225}{16}[/tex]
[tex]x=\frac{225}{16}[/tex]
For extraneous solution, Substitute the value of x back in the equation.
[tex] -4\sqrt (\frac{225}{16})-3=12[/tex]
[tex]-4\times\frac{15}{4}-3=12[/tex]
[tex]-15-3=12[/tex]
[tex]-18\neq12[/tex]
The value of x does not satisfy the equation which means the value of x is an extraneous solution.
So, [tex]x=\frac{225}{16}[/tex] is an extraneous solution.

Parallelogram MNPQ was dilated to create parallelogram M'N'P'Q'.
Which statements are true about the parallelograms? Check all that apply.
The length of side MN is 2 units.
The length of side M'N' is 5 units.
The image is smaller than the pre-image.
Sides MQ and M'Q' both have the same slope, 1.
The scale factor is 2/5
Answer:
Options 1,2 and 4 are correct.
Step-by-step explanation:
We have been given a parallelogram MNPQ was dilated to create parallelogram M'N'P'Q' and we asked to find out which of the given options are correct.
Let us see all the options one by one.
On using distance formula we can see that side MN is 2 units.
[tex]MN=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2} }[/tex]
[tex]MN=\sqrt{(4-2)^{2} +(-2-(-2))^{2} }[/tex]
[tex]MN=\sqrt{(2)^{2} } =2[/tex]
Therefore,option 1 is correct.
We can find the side M'N' by distance formula as we solved for side MN. After solving for M'N' we will get 5 units. Therefore, option 2 is also correct.
Now let us see third option. We can see that image M'N'P'Q' is bigger than pre-image MNPQ. Therefore, option 3 is false.
Now look at our option 4.
Since we know slope is rise (difference of y coordinates) over run (difference of x coordinates) . Upon looking at our image and pre-image we can see that as we increase our x coordinate by one unit our y coordinate also increase by one.
Therefore, option 4 is correct indeed.
Upon looking at our fifth option we can see that our image is bigger than our pre-image. If our image was dilated by factor of 2/5 it would have been smaller than our pre-image. We can see the scale factor is 5/2 instead of 2/5.
Therefore, our fifth option is false.
Considering the slopes and scale factor of the diagram given, the statements that are true about the parallelogram are: A, B, and D.
How to find SlopeSlope = vertical distance / horizontal distance = change in y / change in x.
How to find Scale FactorScale factor = length of image/corresponding length of pre-image.
Find the length of MN:
MN = |4 - 2| = 2 units (Option A is true).
Find M'N':
M'N' = |10 - 5| = 5 units (Option B is true).
MNPQ is the pre-image, while M'N'P'Q' is the image, therefore, the image is bigger than the pre-image. (Option C is NOT true).
Find Slope of MQ:
Slope = 1/1 = 1
Find Slope of M'Q':
Slope = 2/2 = 1 (Option D is true).
Find the scale factor:
Scale factor = dimension of image/dimension of pre-image = M'N'/MN
Scale factor = 5/2 (Option E is NOT true).

What is a distributive property of 72 divided by 4
Answer:
[tex]\frac{72}{4}=18[/tex]
Step-by-step explanation:
To find : What is a distributive property of 72 divided by 4 ?
Solution :
The distributive property of division is given by,
[tex]\frac{a+b}{c}=\frac{a}{c}+\frac{b}{c}[/tex]
We have to divide 72 by 4,
So, Re-write 72 as 60+12.
Substitute,
[tex]\frac{72}{4}=\frac{60+12}{4}[/tex]
[tex]\frac{72}{4}=\frac{60}{4}+\frac{12}{4}[/tex]
[tex]\frac{72}{4}=15+3[/tex]
[tex]\frac{72}{4}=18[/tex]
Therefore, [tex]\frac{72}{4}=18[/tex]
While the distributive property is typically relevant for multiplication over addition or subtraction, you can apply it to division by first rewriting the division as multiplication by the reciprocal. For example, 72 divided by 4 can be rewritten as 72 times 1/4, and then distributed over a sum or difference.
Explanation:The distributive property involves multiplication and addition or subtraction, not division. However, if we interpret your question in a bit different way, we can make use of the distributive property for division. To start, dividing 72 by 4 is the same as multiplying 72 by 1/4. So, we can rewrite it as follows:
72 * 1/4
The distributive property is applied when you multiply a number by a sum or a difference. For example, in case of [tex]72*1/4 = (40+32)*1/4[/tex], it would distribute as: [tex]40*1/4 + 32*1/4[/tex]. It gives us 10 + 8 = 18 which is the correct answer. This way, the distributive property can be used in division if the division is expressed as a multiplication.
