Which of the following expressions is equivalent to the expression below?

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:

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.

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!

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]

We have to write in simplest form

7/6 divided by 8

[tex]7/6 \div 8 \\\\= \dfrac{7}{6} \times \dfrac{1}{8}\\\\= \dfrac{7}{48}[/tex]

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.
