Step-by-step explanation:

Answer:

The two integers are 20 and 22.

Step-by-step explanation:

Let x be the first integer.

[tex](x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20[/tex]

Applying the difference of squares, and solving the equation, it is found that the numbers are 20 and 22.

----------------------

[tex]D_s = (n+2)^2 - n^2[/tex]

Expanding the difference:

[tex]D_s = n^2 + 4n + 4 - n^2[/tex]

[tex]D_s = 4n + 4[/tex]

----------------------

The difference is 84, thus:

[tex]D_s = 84[/tex]

Now, we solve for n.

[tex]4n + 4 = 84[/tex]

[tex]4n = 80[/tex]

[tex]n = \frac{80}{4}[/tex]

[tex]n = 20[/tex]

----------------------

Thus, the numbers are: [tex]n = 20[/tex] and [tex]n + 2 = 20 + 2 = 22[/tex]

Answer:

x = 55.06531425, or 55

Step-by-step explanation:

(x/68) = tan(39)

68 * (x/68) = 68 * tan(39)

x = 55.06531425, or 55

Answer:

[tex]\huge\boxed{x \approx 55}[/tex]

Step-by-step explanation:

We need to note that this is an equation, in which we can solve for x.

[tex]tan(39) = \frac{x}{68}[/tex]

We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.

We now have the formula simplified down to [tex]0.81 = \frac{x}{68}[/tex]. To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.

We know have [tex]0.81 \cdot 68 = x[/tex]

[tex]0.81 \cdot 68 = 55.08 \approx 55[/tex], so x is approximately 55.

Hope this helped!

Delta Math

The density of a material 4 kg/cup on converting it into pounds per liter will be 37.2 lbs/lt.

What are derived units?

Defining a derived unit is the process of deriving a measurement unit from one or more of the seven base units of the International System of Units (SI). There are two types of derived units: dimensionless and the product of base units.

Here it is given that, the density d of a certain material is 4 kilograms per cup of volume and it is find the density of material in pounds per liter.

Now it is known that,

1 kg equals 2.2 pounds

and, 1 cup of volume equals 0.237 lt.

converting the density d of material in pounds per liter and Rounding it to the nearest tenth :

[tex]\begin{aligned}d&= 4\:\frac{\text{kg}}{\text{cup}}\\&=\:\frac{4\cdot2.2\text{ pounds}}{0.237\:\text{lt.}}\\&\approx 37.2\:\frac{\text{ pounds}}{\:\text{lt.}}\end{aligned}[/tex]

Therefore, the density of a material 4 kg/cup on converting it into pounds per liter will be 37.2 lbs/lt.

Answer:

Step-by-step explanation:

Given that:

Amount borrowed = principal = p = $15000

Interest % per year = r = 6% = 0?06

Total Interest paid = $4500

Number of years it took to repay the loan (t) =?

Simple interest = (p * r * t)

4500 = (15000 * 0.06 * t)

4500 = 900t

4500 / 900 = t

5 = t

It tool 5 years to repay the loan

Angle between the pair of straight lines is zero therefore the lines are parallel.

Hence proved

Angle between the pair of straight lines is zero therefore the lines are parallel.

Parallel lines can be defined as two lines in the same plane that their angle of inclidation is equal and never meet.

Given,

x²+6xy+9y²-4x+12y-5=0

Comparing the equation with the general equation of 2nd degree

ax² + ay² + 2gx + 2fy + c = 0

Answer:  the  answer  is  7/48

Step-by-step explanation:

The simplest form of the division is 7/48.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, [tex]a \div b = a[/tex] divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

Answer:

On 01 January 2021: Debit Cash for $50,000; and Credit Note payable for $50,000.

On 31 Jan 2021: Debit Interest expense for $250; Debit Note payable for $578.64; and Credit Cash for $828.64.

On 28 Feb 2021: Debit Interest expense for $247.11; Debit Note payable for $581.53; Credit Cash for $828.64.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

On January 1, 2021, Tropical Paradise borrows $50,000 by agreeing to a 6%, six-year note with the bank. The funds will be used to purchase a new BMW convertible for use in promoting resort properties to potential customers. Loan payments of $828.64 are due at the end of each month with the first installment due on January 31, 2021.

Record the issuance of the installment note payable and the first two monthly payments.

The explanation to the answer is now given as follows:

Date                Account Title                     Dr ($)                 CR ($)        

01 Jan 2021    Cash                                  50,000

                          Note payable                                            50,000

                        (To record $50,000 borrowing through 6% Note from the bank.)

31 Jan 2021     Interest expense (w.1)        250

                         Note payable (w.2)            578.64

                            Cash                                                         828.64

                          (To record first month interest expense paid and part payment of $50,000 note.)

28 Feb 2021    Interest expense (w.4)       247.11

                         Note payable (w.5)            581.53

                             Cash                                                        828.64

                          (To record second month interest expense paid and part payment of $50,000 note.)

Workings:

w.1: Interest expense = First month interest expense = (Interest rate / 12) * Loan amount = (6% / 12) *$50,000 = $250

w.2: Note payable = First month part payment of note payable principal = Monthly payment - First month interest expense = $828.64 - $250 = $578.64

w.3: Loan balance after first month = Loan amount - First month part payment of note payable principal = $50,000 - $578.64 = $49,421.36

w.4: Interest expense = Second month interest expense = (Interest rate / 12) * Loan balance after first month = (6% / 12) *$49,421.36 = $247.11

w.5: Note payable = Second month part payment of note payable principal = Monthly payment - Second month interest expense = $828.64 - $247.11 = $581.53

Answer:

1. During part 2. The y-axis (line going up) represents his distance. At part 1, his distance stays the same because he is sitting in the park. At part 2 we see the line go down, which means his distance from home is decreasing.

2.At part 3. His distance stays the same, which represents him waiting in line. We know this because the line stays at the same distance and the time increases(this is the x-axis)

3. There would be another part of the graph. If he had stopped again, there would have been another straight line with the distance the same and the time increasing.
