Answer:

Step-by-step explanation:

3.75 is a2 x (b-c)

4.85 gose with the b + c -a

3.3 gose to the a - b + c

you should now know the last one

Answer 2

Answer:

1. A² × ( B - C ) = 3.75

2. B + C - A = 3.65

3. A - B + C = 4.85

4. B × ( A - C ) = 3.3

Step-by-step explanation:

1. (5 × 5) × (4.4 - 4.25)

    25 × .15 = 3.75

2. (4.4 + 4.25) - 5

     8.65 - 5 = 3.65

3. (5 - 4.4) + 4.25

     .6 + 4.25 = 4.85

4.  4.4 × ( 5 - 4.25 )

      4.4 × .75 = 3.3

Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current rent. Let r represent Cody's current rent. Set up an equation and solve it to fibd the value of r.

Answers

Given :

Cody's rent is increasing by $51 per month starting next year.

That is an increase of 15% from his current rent.

Let the current rent = r

so, the increase = 15% of r = 0.15r

So, the equation that represent the situation is :

[tex]0.15\cdot r=51[/tex]

Solve for r :

[tex]r=\frac{51}{0.15}=340[/tex]

So, the current rent = $340

The rent for the next year = 340 + 51 = $391

How many pounds of N are in 2 tons of manure (4.8% N)?

Answers

Answer: 192 lbs

Total weight of manure = 2 tons

Step1: we need to converts tons to pounds

1 ton = 2000 lb

2 tons = x lb

Cross multiply

2 x 2000 = 1 * x

x = 2 x 2000

x = 4000 lbs

Therefore, 2 ton of manure = 4000 lbs of manure

We have 4.8% of N in the manure

Pounds of N = 4.8/100 x 4000

Pounds of N = 0.048 x 4000

Pounds of N = 192 lbs

The pounds of N in 2 tons of manure is 192 lbs

Max's bedroom is rectangular shaped and has a total area
of 140 square feet. If the short wall is at 10 feet long,
what is the length of the longer wall?

Answers

Answer:

14 ft

Step-by-step explanation:

Area is length times width. So, you need to find something times 10 that equals 140. Or, you could just do 140 divided by 10. 140/10=14.

Write the equation of the function shown below. Identify domain and range.

Answers

The function can be split in 2 straight lines: the first one from x = 2 to the left, and the other one from the same point to the right.

Now, a straight line equation is of the form

[tex]ax+m[/tex]

Where a is the slope and m is the y-intercept.

"Left" line:

- m (y-intercept):

To find it we need to see where the line cross (intercepts) the y-axis. From the figure we can see that m = -2.

- a (slope):

To calculate the slope, we can use the following equation:

[tex]a=\frac{\Delta y}{\Delta x}[/tex]

Where, chossing 2 points in the line, we have:

[tex]\begin{gathered} \Delta y=how\text{ much do we move up or down between the 2 points} \\ \Delta x=\text{ how much do we move to the right betw}en\text{ the 2 points} \end{gathered}[/tex]

Look that for x we have to move to the right. Let's see a drawing:

In our case, we can take the points (0, -2) and (2, 4), so, we have:

[tex]a=\frac{\Delta y}{\Delta x}=\frac{4-(-2)}{2-0}=\frac{6}{2}=3[/tex]

So, we have the equation for the "left" line:

[tex]3x-2[/tex]

-"Right" line:

- m (y-intercept):

In this case we can not see where the line cross (intercepts) the y-axis. Let's leave this for latter.

- a (slope):

As we did before, we can pick to points on the line, like (3, 1) and (2, 4).

[tex]a=\frac{\Delta y}{\Delta x}=\frac{1-4}{3-2}=\frac{-3}{1}=-3[/tex]

- m (y-intercept) continues:

We now know that the equation for this line is:

[tex]-3x+m[/tex]

To find m, we can pick one single point and solve for that variable. For example, taking the point (2,4), we have:

[tex]\begin{gathered} y=ax+m \\ y=-3x+m \\ 4=-3\cdot(2)+m \\ 4=-6+m \\ 4+6=m \\ 10=m \end{gathered}[/tex]

And so, for the right line, we have:

[tex]-3x+10[/tex]

Finally, the equation of the function can be written as:

[tex]f(x)=\begin{cases}3x-2\text{ if x }\leq\text{ 2} \\ -3x+10\text{ if x }\ge\text{ 2}\end{cases}[/tex]

Now, the domain of the function is the set of points (or numbers) for which the function has values. The set of departure. In this case, all the numbers can be "trasnformed" or mapped with this function, so the domain is all the numbers, the set of real numbers, R:

[tex]\begin{gathered} -\inftyLastly, the range of the function is the complete set of all possible resulting values after aplying the function. We can see that the function can takes, as maximum, a value of 4, then the range is:[tex]\begin{gathered} (\infty;\text{ 4}\rbrack \\ or \\ y\leq4 \end{gathered}[/tex]

Given that Sarah spent half of her weekly allowance.

She earns $4.70 for washing dogs.

The final amount is $ 13.50.

Let x be the weekly allowance.

She spent half of her allowance so she has half of the allowance.

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

She earns $ 4.70, add this to her half of the allowance.

[tex]\frac{x}{2}+4.70[/tex]

This is equal to 13.50.

[tex]\frac{x}{2}+4.70=13.50[/tex]

Subtracting 4.70 from both sides, we get

[tex]\frac{x}{2}+4.70-4.70=13.50-4.70[/tex]

[tex]\frac{x}{2}=8.80[/tex]

Multiplying 2 on both sides, we get

[tex]\frac{x}{2}\times2=8.80\times2[/tex][tex]x=17.60[/tex]

Hence Sarah's weekly allowance is $ 17.60.

Answers

SOLUTION:

Case: Present Value

Present Value is the value of an expected income stream determined as of the date of valuation. The present value is usually less than the future value because money has interest-earning potential.

Part 1

[tex]PV=\frac{FV}{(1+i)^{nt}}[/tex]

Sentence:

The Present Value is the Future Value divided by 1 is added to the rate of returns(i), raised to the number of periods(nt).

Part 2:

Present Value of Ordinary Annuity

[tex]PVOA=C[\frac{1}{i}-\frac{1}{i(1+i)^{nt}}][/tex]

C is the annuity payment deposited or received at the end of each period.

i= discount or interest rate per period

n= number of periods.

The factor with interest rate and the number of periods is multiplied by annuity payments

Part 3:

Present value of Annuity due

[tex]PVAD=C[\frac{1}{i}-\frac{1}{i(1+i)^{nt-1}}]+C[/tex]

C is the annuity payment deposited or received at the end of each period.

i= discount or interest rate per period

n= number of periods.

The factor with interest rate and the number of periods less 1 is multiplied by annuity payments and then added again to the annuity payments

The first aircraft has 65 more seats than the second aircraft. The third aircraft has 41 fewer seat than the second aircraft. If their total number of seats is 402, find the number of seats for each aircraft.

Answers

Solution:

Let A be the first aircraft

Let B be the second aircraft

Let C be the third aircraft

Here is the information that is given in the question:

The first aircraft has 65 more seats than the second aircraft:

A = B + 65

The third aircraft has 41 fewer seats than the second aircraft

C = B - 41

their total number of seats is 402

A + B + C = 402

Now substitute the values in the 1st and 2nd equations into the 3rd.

(B+65) + B + (B-41) = 402

this is equivalent to:

3B + (65-41) = 402

this is equivalent to:

3B + 24 = 402

this is equivalent to:

3B = 402 - 24 = 378

solving for B, we get:

[tex]B\text{ = }\frac{378}{3}=126[/tex]

We can conclude that the correct answer is:

first aircraft A:

A = B + 65 = 126 + 65 = 191

that is:

A = 191

second aircraft:

B = 126

third aircraft:

C = B - 41 = 126 - 41 = 85

that is:

C = 85
