Patti green and her husband are purchasing a condominium for $123,000. They have $15,000 for a down payment. What is the amount of their mortgage loan?

Answer:

x = 53 degrees

Step-by-step explanation:

Alternate exterior angles are equal if  two parallel lines are cut by a transversal.

 If  m and n are parallel, then

3x-28 = 2x+25

Subtract 2x from each side.

3x-28-2x = 2x+25-2x

x-28 =25

Add 28 to each side.

x-28+28 = 25+28

x = 53

Answer: The value of x = 90°

and the value of y = 43°

Step-by-step explanation:

Since we have given that

In ΔABC,

∠B=∠C=47°

As we know that "Sum of all three angles of a triangle is 180° ".

So, it becomes,

[tex]\angle A+\angle B+\angle C=180\textdegree\\\\\angle A+47\textdegree+47\textdegree=180\textdegree\\\\\angle A+94\textdegree=180\textdegree\\\\\angle A=180\textdegree-94\textdegree\\\\\angle A=86\textdegree\\\\So,\\\\y=\frac{86}{2}=43\textdegree[/tex]

Similarly,

Now, in ΔABD,

[tex]\angle A+\angle B+\angle ADB=180\textdegree\\\\43\textdegree+47\textdegree+\angle ADB=180\textdegree\\\\90\textdegree+\angle ADB=180\textdegree\\\\\angle ADB=180\textdegree-90\textdegree\\\\\angle ADB=90\textdegree[/tex]

Hence, the value of x = 90°

and the value of y = 43°

Answer:

1st number = 18

2nd number = -5

Step-by-step explanation:

Let x be first number and y be the 2nd number.

We have been given that first number plus twice a second number is 8. We can represent this information as:

[tex]x+2y=8...(1)[/tex]

We are also given that twice the first number plus the second totals 31. We can represent this information as:

[tex]2x+y=31...(2)[/tex]

Now let us solve our system of equations using substitution method.

From equation (1) we will get,

[tex]x=8-2y[/tex]

Substituting [tex]x=8-2y[/tex] in equation (2) we will get,

[tex]2(8-2y)+y=31[/tex]

[tex]16-4y+y=31[/tex]

[tex]-4y+y=31-16[/tex]  

[tex]-3y=15[/tex]  

[tex]y=\frac{15}{-3}[/tex]

[tex]y=-5[/tex]

Therefore, the second number is -5.

Now let us substitute y=-5 in equation (1).

[tex]x+(2*-5)=8[/tex]

[tex]x-10=8[/tex]

[tex]x=8+10[/tex]

[tex]x=18[/tex]

Therefore, the first number is 18.

The numbers are x = 18 and y = -5.

The question involves a system of linear equations and requires solving for two unknown numbers. Using variables to represent these numbers, the system can be written as:

First equation: x + 2y = 8,

Second equation: 2x + y = 31.

To solve this system, follow these steps:

Multiply the first equation by 2, obtaining the equation 2x + 4y = 16.

Subtract the second equation from this result to eliminate x, leading to 3y = -15.

Divide by 3 to find y = -5.

Substitute y = -5 into any original equation to solve for x.
Using the first equation: x + 2(-5) = 8, therefore x = 18.

The solution to the system is x = 18 and y = -5.

Answer:

a) 5.4%  

Step-by-step explanation:

a) We will use the binomial distribution, with n = 100 and p(success) = 0.95

We need to calculate

P(X=x) = [tex]\binom{n}{x}p^{x}q^{n-x}[/tex]

P(X ≤91) =  [tex]\sum_{k=1}^{91}\binom{100}{k}0.95^{k}0.5^{n-k}[/tex]

As we know that binomial distribution can be approximated to normal distribution if np≥5 and nq≥5 as in this case.

Therefore, P(x,n,p) →N[tex](\mu, \sigma )[/tex]

[tex]\mu[/tex] = np = 95

[tex]\sigma[/tex] = √npq = 2.`79

P(X≤91) ≅ P(X≤91.5)  = P( Z≤[tex]\frac{91.5-95}{2.179}[/tex]

                                 =  P( Z≤ -1.6)

                                 = 0.054

Probability = 5.4%

b) If the probability was less than 5% then we must say that the DHL Shipping company don not ships 95% of its orders on time but as we can see that the probability is more that 5% that is 5.4%. So, we cannot say that the company does not ships the orders on time. But we cannot say with confirmation, we need more samples so as to judge accordingly.

Answer:

[tex]\$4701.80[/tex]

Step-by-step explanation:

Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate and she gets a loan payoff of 60 months,

We know that,

[tex]\text{PV of annuity}=P\left[\dfrac{1-(1+r)^{-n}}{r}\right][/tex]

Where,

PV = Present value of annuity = 25000,

r = rate of interest of each period = [tex]\dfrac{7}{12}[/tex]% monthly

n = number of periods = 60 months,

Putting the values,

[tex]\Rightarrow 25000=P\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right][/tex]

[tex]\Rightarrow P=\dfrac{25000}{\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right]}[/tex]

[tex]\Rightarrow P=\$495.03[/tex]

Hence total amount paid is,

[tex]=495.03\times 60=\$29,701.80[/tex]

Therefore interest amount is,

[tex]=29,701.80-25,000=\$4701.80[/tex]

Answer:

1/6 p -4/5

Step-by-step explanation:

- 2/3p + 1/5 - 1 + 5/6p

When I combine like terms, I put them next to each other.

- 2/3p + 5/6p+ 1/5 - 1

We need to get a common denominator of 6 for the p terms

-2/3 *2/2 p + 5/6 p

-4/6p + 5/6 p

1/6 p

We need to get a common denominator of 5 for the contant terms

1/5 - 1*5/5

1/5-5/5

-4/5

Substituting these in

2/3p + 5/6p+ 1/5 - 1

1/6 p -4/5

Answer: hot dog = $1.75

Step-by-step explanation:

Let h represent hot dogs and c represent bags of chips.

Customer 1: 4h + 2c = 9.00  →  3(4h + 2c = 9.00)  →  12h + 6c =  27.00

Customer 2: 5h + 3c = 11.75 → -2(5h + 3c = 11.75)  → -10h - 6c = -23.50

                                                                                       2h        =    3.50

                                                                                      ÷2               ÷2    

                                                                                        h        =    1.75

Final answer:

The cost of one hot dog is determined to be $1.75.

Explanation:

To find the cost of a hot dog, we will use the information given in two different customer purchases to set up a system of linear equations. Let's define H as the cost of one hot dog and C as the cost of a bag of chips. The first customer buys 4 hot dogs and 2 bags of chips for $9.00, which gives us the first equation:

4H + 2C = 9.00 ...(1)

The second customer buys 5 hot dogs and 3 bags of chips for $11.75, which provides us with the second equation:

5H + 3C = 11.75 ...(2)

With two equations, we can solve for H by either substitution or elimination. Let's multiply equation (1) by 3 and equation (2) by 2 to eliminate C:  

Subtracting equation (4) from equation (3) gives us:

2H = 3.50

And dividing both sides by 2:

H = 1.75

Therefore, the cost of one hot dog is $1.75.

Look at the picture.

Answer:

17 regular popcorn bags and 23 super size bags.

Step-by-step explanation:

A group of 40 people went to the theme park. While there, each person bought popcorn.

Let the regular popcorn bags be = x

Let the super size bags be = y

[tex]x+y=40[/tex]        ................(1)

Next equation becomes:

[tex]6x+8y=286[/tex]        ...............(2)

Multiplying (1) by 6 : [tex]6x+6y=240[/tex]

Now subtracting this from (2) we get,

[tex]2y=46[/tex]

=> y = 23

And x = [tex]40-23[/tex]

=> x = 17

So, there were 17 regular popcorn bags and 23 super size bags that the group bought.

Answer:

Yes they are proportional!

The factors of 28 that we can use in these fractions are 4 and 7.  To find if these are proportional, just simplify 8/28.  To do so divide the numerator (top) and the denominator (bottom) both by 4...

8/28 / 4 = 4/7

Now that you have both with the same denominator, you can evaluate if 3/7 and 4/7 are proportional.  In this case they are.

Hope this helps! :)

Answer: 838860

=========================================

Plug in x = 0 to find y = f(x)

f(x) = 4^(2x+1)

f(0) = 4^(2*0+1)

f(0) = 4

The point (0,4) is on the function curve

Plug in x = 5 and compute

f(x) = 4^(2x+1)

f(5) = 4^(2*5+1)

f(5) = 4194304

The point (5, 4194304) is on the function curve

Once you have these two points, you use the slope formula to compute the average rate of change

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

m = (4194304 - 4)/(5-0)

m = 838860

The slope of the line through the two points found earlier is m = 838860, so this is the average rate of change on f(x) for the interval from x = 0 to x = 5.

When a = 1, the equation becomes x² - 6x = -13.

To rewrite the equation 8x² - 48x = -104 with the coefficient of x² as 1,

you can divide the entire equation by 8,

which is the coefficient of x²:

(8x² - 48x) / 8 = (-104) / 8

Now, simplify:

x² - 6x = -13

So, when a = 1, the equation becomes x² - 6x = -13.

Step-by-step explanation:

1. If you work these out in detail, they are tedious, but not difficult. Fortunately, you can take advantage of certain clues to simplify the work.

___

2. You know the -x as an argument of the function will flip the curve left-to-right, so only C and D are potential choices. One way to resolve the ambiguity is to see what the function value is for x=0. You find they are the same:

... f(0) = root(3)(0 -1) = g(0) = root(3)(-0-1) = root(3)(-1)

Only graph C has the two curves crossing at x=0.

___

f(x) = root(3)(x -1) is a shift to the right of the parent function root(3)(x).

Replacing x by -x reflects that function across the y-axis, so what was a shift to the right now becomes a shift to the left, as seen in graph C.

Answer:F=−20d+1500

Step-by-step explanation:he amount of filling used to make each dumpling is constant, so we're dealing with a linear relationship.

We could write the desired formula in slope-intercept form: F=\greenD md+\maroonD bF=md+b. In this form, \greenD mm gives us the slope of the graph of the function and \maroonD bb gives us the yy-intercept. Our goal is to find the values of \greenD mm and \maroonD bb and substitute them into this formula.

Hint #22 / 3

We know that each dumpling Dominik makes decreases the filling remaining by 2020 grams, so the slope \greenD mm is \greenD{-20}−20, and our function looks like F=\greenD{-20}d+\maroonD bF=−20d+b.

We also know that Dominik has 15001500 grams of filling initially, so the yy-intercept \maroonD{b}b is \maroonD{1500}1500.

Hint #33 / 3

Since \greenD{m}=\greenD{-20}m=−20 and \maroonD{b}=\maroonD{1500}b=1500, the desired formula is:

The function's formula for the grams F of filling remaining as a function of d, the number of dumplings Dominik makes, is given by:F(d) = 1500 - 20d

To derive this formula, we start by considering the total amount of filling Dominik has, which is 1500 grams. Each dumpling uses 20 grams of filling. Therefore, if Dominik makes d dumplings, he will have used 20d grams of filling. To find the remaining filling, we subtract the amount used from the total amount initially available:

[tex]\[ F(d) = \text{Total filling} - (\text{Filling per dumpling} \times \text{Number of dumplings}) \] \[ F(d) = 1500 - (20 \times d) \] \[ F(d) = 1500 - 20d \][/tex]

This function gives us the amount of filling, in grams, that remains after Dominik has made d dumplings.

Final answer:

Hannah initially has 8/9 of a pound of birdseed, and after using 2/3 of a pound, she has 2/9 of a pound remaining, which is calculated by finding a common denominator and subtracting the second fraction from the first.

Explanation:

Hannah initially has 8/9 of a pound of birdseed. After filling her bird feeders with 2/3 of a pound of birdseed, we need to subtract the amount she used from what she started with to find out how much birdseed she has left. The calculation we'll use is:

(initial amount) - (amount used) = (amount remaining)

In fractional form, this becomes:

8/9 - 2/3

To subtract these fractions, we need a common denominator. The smallest common denominator for 9 and 3 is 9. We can convert 2/3 to 6/9 by multiplying the numerator and the denominator by 3. After this step, the subtraction is straightforward:

8/9 - 6/9 = 2/9

Hence, Hannah has 2/9 of a pound of birdseed remaining.
