Final answer:

Solve the equation 3/2x - 4 = 16 by adding 4 to both sides, simplifying to 3/2x = 20, and then multiplying both sides by 2/3 to find the solution, x = 40/3.

Explanation:

To solve the equation 3/2x - 4 = 16, you need to perform a series of algebraic manipulations.

Add 4 to both sides of the equation to isolate the term with the variable on one side: 3/2x = 16 + 4.

Combine like terms: 3/2x = 20.

To find x, multiply both sides by the reciprocal of 3/2, which is 2/3: x = 20 * (2/3).

Simplify the multiplication: x = 40/3 or x = 13.33 repeating.

Therefore, the solution to the equation is x = 40/3.

Answer:

The answer to your question is: cost = $4000

Step-by-step explanation:

Data

Volume = 8000 ft³

cost = $10 / square foot

Process

It's a  cube then we find the length of one side

Volume = l³ = 8000

                l = ∛8000

                I = 20 ft

Now, calculate the area of the floor,

Area = l x l

        = 20 x 20

        = 400

Finally, find the cost of the floor

cost = area x price

cost = 400 x 10

       = $4000

Final answer:

To calculate the cost of the hardwood floor for a cubic room with a volume of 8,000ft³, we first find the length of one side of the cube (20ft), then calculate the floor area by squaring that length (400ft²), and multiply it by the contractor's charge ($10/ft²) to get the total cost ($4000).

Explanation:

The question involves calculating the cost of adding hardwood floors to a cubic room, with knowledge of its volume. First, we need to find the length of one side of the cube to determine the floor area. Since the volume of a cube is found by cubing the length of one side, we find the cube root of the room's volume:

∛(8,000ft³) = 20ft (this is the length of one side of the cube).

Then the area of the floor, which is a square, is calculated by squaring the length of the side:

Area = side² = (20ft)² = 400ft².

Finally, to find the cost, we multiply the area by the contractor's charge per square foot:

Cost = area × charge per square foot = 400ft² × $10/ft² = $4000.

Therefore, the hardwood floor will cost $4000.

The correct option is (c) $1,354,500 The total sale price of Farmer Donald's property is calculated by converting square miles to acres (1 square mile = 640 acres), adding the additional 5 acres, and then multiplying by the sale price per acre to get the total of $1,354,500.

To calculate the total sale price of the property Farmer Donald is selling, we need to find the total number of acres for both parcels of land and then multiply that by the price per acre.

First, we convert the one square mile to acres, knowing that one square mile equals 640 acres:

Parcel 1: 1 square mile = 640 acres

Parcel 2: 5 acres

Adding the two parcels together gives us:

Total acres = 640 acres + 5 acres = 645 acres

Next, we multiply the total acres by the price per acre:

Total sale price = 645 acres \\u00D7 $2,100 per acre

Total sale price = $1,354,500

Therefore, the total sale price of the property is $1,354,500.

42

42x2 is 84 and 42x5 is 210

Final answer:

The greatest common factor (GCF) of 84 and 210 is 42, which is found by listing the factors of each number and identifying the largest one they share.

Explanation:

The student is asking for the greatest common factor (GCF) of the number of pages in two books, one with 84 pages and another with 210 pages. To find the GCF, we need to list the factors of each number and then identify the largest factor they have in common.

The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. The factors of 210 are 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210. The common factors of 84 and 210 are 1, 2, 3, 6, 7, 14, 21, and 42. The largest of these is 42, so the GCF is 42.

Answer: 33 333,33 per month or 400 000 per year

Step-by-step explanation:

You need 48 000 + 0.035X = 62 000

So ( 62 000 - 48 000 ) / 0.035 = X

Then you can divide X per 12 (months in a year)

And you have your answer per month .

So 33 333,33 total sale per month to have at least as high as the average pay

An equation is formed of two equal expressions. Andre’s total sales need to be $400,000 for his pay to be at least as high as the average pay for this job.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Andrew will earn $48,000 per year plus 3.5% of his total sales, the average pay for this job is $62,000. Therefore, the amount of sales that Andrew needs to make in order to make his pay equal to the average pay is,

Average pay = Annual pay + 3.5% of sales

$62,000 = $48,000 + (3.5/100)x

$62,000 - $48,000 = 0.035x

$14,000 = 0.035x

$14,000 / 0.035 = x

x = $400,000

Hence, Andre’s total sales need to be $400,000 for his pay to be at least as high as the average pay for this job.

Answer:

y = b + kn

Step-by-step explanation:

In any given year, the salary of each will be given by the equation

y = b + kn where

y = Salary

b= Initial salary before increment

k= Increment

n= is the year in question

Thus, this can be proven by equating the salaries of both workers.

Jose's salary will be $48,000 + $2800n

Victor's salary will be $59000 + $1700n

Thus, to get the particular year, we equate both as

$48,000 + $2800n = $59000 + $1700n

$2800n -$1700n =$59,000 - $48,000

       $1100n =$11000

Canceling the dollar signs throughout, we get

n = 11000/1100 = 10 years.

If you worked his out, you will get that in the 10th year, both salaries will be $76,000.

Thus, the equation is

y = b + kn

with the variables as explained above.

Step-by-step explanation:

we have

[tex]f(x)=x^{2}[/tex]

Find f(-3)

we know that

f(-3) is the value of the function f(x) for the value of x equal to -3

so

substitute the value of x=-3 in the function above to get f(-3)

[tex]f(-3)=(-3)^{2}[/tex]

[tex]f(-3)=9[/tex]

Answer:

Answer is f(x)=245(4^1/12)^12x

Step-by-step explanation:

The general formula for the growth of population in years is:

f(x) =P0(1+r)^x

where 1+r is the rate of growth in this case 4 and x is time in years. To take it to months we do not change initial population , this doesn't vary by changing time scale (there are 45 fruit flies in time 0 )

we change the time period x to 12 x because we want our formula to remain equivalent to the original one so if x = 1 year  in months this would be equivalent to twelve months (12x = 12  with x =1 ) taht is the same

However we need to reescale our growth rate to a value that calculates it by month growth.  After 12 time periods of a month our grow rate should be equivalent to the growth rate of a year. So For that reason we elevate to a  1/12 because of  exponent rules

(4^1/12)^12x  =(4^12x/12) because of exponent of an exponent is multiplying exponents

= (4)^x we arrive to the same expression. So

Answer:

d. $119,743.59

Step-by-step explanation:

actual value (AV)=$180,000

purchase price (PP) =$142,000

intial value (IV) =$18,000

useful live (UL)= 39 years

First, we subtract the value of the property from the purchase value or IV to know the value to be depreciated:

PP-IV= $142,000-$18,000 = $124,000

Then we find out the yearly depreciation by dividing $124,000 into useful live (UL) years:

$124,000/39 = $3,179.49 This is the amount that the property depreciates every year.

But after 7 years the depreciation is: $3,179.49*7= $22,256.41  

We subtract the depreciation in the 7 years from the purchase price (PP) and that's the present book value of the property:  

$142,000-$22,256.41=$119,743.6

To find the present book value of the property, subtract the land value from the purchase price to get the initial building value. Then, calculate the total depreciation over the seven years and subtract this from the initial building value. Finally, add back the land value.

To find the present book value of the property, we need to first determine the value of the structure. We can do this by subtracting the value of the land ($18,000) from the purchase price of the property ($142,000), according to the details given. So, the initial value of the building is $124,000.

Since we use the straight-line method of depreciation, the structure depreciates at a constant amount each year over its useful life. So, the yearly depreciation expense is 124,000 / 39 = $3,179.49.

Then, we'll calculate the total depreciation over the seven years, which is 3,179.49 * 7 = $22,256.43.

Lastly, we'll subtract this total depreciation from the original building value ($124,000 - $22,256.43). This yields a present book value of $101,743.59 for the structure. When we add back the value of the land ($18,000) which does not depreciate, we obtain a total present book value of $119,743.59 for the property.

Therefore, the current book value of the property is d. $119,743.59.

Answer:

  35 years

Step-by-step explanation:

The proportion p that remains after y years is ...

  p = (1/2)^(y/5.27)

In order for 1/100 to remain (the level decays from 100 times to 1 times), we have ...

  .01 = .5^(y/5.27)

  log(0.01) = y/5.27·log(0.5) . . . take logs

  y = 5.27·log(0.01)/log(0.5) ≈ 35.01 ≈ 35 . . . . years

Given that the radioactive isotope cobalt-60 has a half-life of 5.27 years, it will take around 36.89 years for it to decay to a level that is safe for human habitation, assuming the initial level is 100 times the safe limit.

The subject of this question is the half-life of radioactive substances, specifically cobalt-60. The half-life is the time it takes for half of the radioactive atoms to decay. Cobalt-60 has a half-life of 5.27 years. This implies that 50% of the cobalt-60 will remain after 5.27 years, 25% will remain after 10.54 years (two half-lives), 12.5% will remain after 15.81 years (three half-lives), and so forth.

Understanding this concept, we can calculate when the region will be habitable. Currently, the radiation level is 100 times the acceptable limit. We need to determine how many half-lives it will take for the radiation level to reduce to 1% i.e., 1/100 of its original level. Since each half-life reduces the radiation by half, this is equivalent to finding when the cobalt-60 will be reduced to a fraction of 1/(2^n), where 'n' is the number of half-lives. Using n = 7 gives us 1/128, which is less than 1/100 (it will need to be less to be within safe levels).

So, it will take approximately 7 half-lives for the area to become safe for human habitation again. Since the half-life of cobalt-60 is 5.27 years, it will therefore take about 7 * 5.27 = 36.89 years for the region to become habitable once more.

Answer:

The minimum average speed needed in the second half is 270 km/hr

Step-by-step explanation

We can divide the track in two parts. For the first half of the track the average speed the car achieved was 230 km/hr and we need to make sure that the average speed of the full track is 250 km/hr. Then, we can calculate the average speed of the two parts of the track and force this to be equal to 250 km/hr. In equation, defining [tex]v_2[/tex] as the average speed of the second half:

[tex]\frac{230 + v_2}{2}=250[/tex]

Solving for [tex]x[/tex]

[tex]x=250*2-230\\x=500-230\\x=270[/tex]

Therefore, achieving a speed of 270 km/hr in the second half would be enough to achieve an average speed of 250 on the track.

We know that [tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

Then,   [tex]P(A\cup B)=0.08+0.15-0.03= 0.20[/tex]

Hence, the probability that an employee selected at random will need either corrective shoes or major dental work : [tex]P(A\cup B)= 0.20[/tex]

hence, the correct option is (A).

The probability that an employee selected at random will need either corrective shoes or major dental work is 0.20.

The subject of this problem is probability. To find the probability that an employee selected at random will need either corrective shoes or major dental work, you need to add the probabilities of each individual event and then subtract the probability of both events occurring, as this is counted twice.

So, the probability is calculated as:

P(Corrective Shoes or Major Dental Work) = P(Corrective Shoes) + P(Major Dental Work) - P(Both)

Substituting the values from the problem, we have:

P(Corrective Shoes or Major Dental Work) = [tex]0.08 + 0.15 - 0.03 = 0.20[/tex]

So, the probability that an employee selected at random will need either corrective shoes or major dental work is 0.20, matching answer choice A.

Let us consider that

p : an angle is a right angle

and

q : the angle measures 90°.

So, the conditional statement is p ⇒ q. This is true, because the measure of a right angle is 90°.

The contrapositive of "p ⇒ q" is "not q ⇒ not p".

That is, if the measure of an angle is not 90°, then the angle is not right angle.

To find how much wire was used, apply the weight-relationship or mass per unit length specification of the wire. The formula to find the length is ((205 g) / (44.5 g/km)) * 1000m/km. The units cancel out each other, leaving the answer in meters.

To compute the length of the copper wire used, you would need to apply the weight-relationship or mass per unit length specification of the 40-gauge copper wire to the weight reduction of the spool. In precise terms, the unit of weight-relationship is given in grams per kilometer (g/km). Thus, the weight of the wire is directly proportional to its length.

So, to verify the length of wire used in meters, you would calculate:

((205 g) / (44.5 g/km)) * 1000m/km

This expression would give the length of the wire that has been used in meters. The units of the calculation effectively cancel out each other, leaving with the expected unit of meters.

Step-by-step explanation:

El movimiento descripto es de tipo rectilineo uniformemente variado, más precisamente tiro vertical.

Para calcular la posición al cabo de 1 seg utilizaremos la ecuacionecuación del movimiento descrita como:

y = v0.t - 1/2 g t^2

Donde y es la altura para cualquier momento

v0 es la velocidad inicial 18 m/s

g la aceleración de la gravedad 9.81 m/s2

y t el tiempo medido en segundos

Entonces para calcular la altura después de un segundo:

y = 18 m/s x 1 seg - 1/2 9.81 m/s2 (1 seg)^2 = 18 m - 4.9 m = 13.1 m

La posición de la pelota, que fue pateada verticalmente hacia arriba desde una altura de 3 metros con una velocidad inicial de 18 m/s, después de 1 segundo, es aproximadamente 11.1 metros por encima del punto de inicio.

La pregunta trata sobre un problema de física relacionado con el movimiento vertical de un objeto. En este caso, una pelota es pateada verticalmente hacia arriba desde una altura de 3 metros con una velocidad inicial de 18 m/s. Para resolverla, podríamos usar la segunda ley del movimiento de Newton para el movimiento vertical, que se puede escribir de la siguiente manera: y = y0 + v0t - 1/2gt^2.

Aquí, y es la posición de la pelota después de un tiempo t, y0 es la posición inicial (3 metros en este caso), v0 es la velocidad inicial (18 m/s), g es la aceleración debido a la gravedad (9.8 m/s^2), y t es el tiempo (1 segundo).

Si sustituimos los valores correspondientes en la ecuación, obtenemos: y = 3m + 18m/s * 1s - 1/2 * 9.8m/s^2 * (1s)^2. Al hacer la respectiva operación, encontramos que la posición de la pelota después de 1 segundo es de aproximadamente 11.1 metros por encima del punto de inicio.

Step-by-step explanation:

We are given that triangle PQR lies in the xy-plane, and coordinates of Q are (2,-3).

Triangle PQR is rotated 180 degrees clockwise about the origin and then reflected across the y-axis to produce triangle P'Q'R',

We have to find the coordinates of Q'.

The coordinates of Q(2,-3).

180 degree clockwise  rotation about the origin  then transformation rule

The coordinates (2,-3) change into (-2,3) after 180 degree clockwise rotation about origin.

Reflect across y- axis the transformation rule

Therefore, when reflect across y- axis then the coordinates (-2,3) change into (2,3).

Hence, the coordinates of Q(2,3).

After applying the sequence of transformations, the coordinates of Q′ are Q' (2, 3).

In Mathematics and Geometry, the rotation of a point 180° about the origin in a clockwise or counterclockwise direction would produce a point that has these coordinates (-x, -y).

Additionally, the mapping rule for the rotation of any geometric figure 180° clockwise or counterclockwise about the origin is represented by the following mathematical expression:

Answer:

(a) If f and t are both even functions, product ft is even.

(b) If f and t are both odd functions, product ft is even.

(c) If f is even and t is odd, product ft is odd.

Step-by-step explanation:

Even function: A function g(x) is called an even function if

[tex]g(-x)=g(x)[/tex]

Odd function: A function g(x) is called an odd function if

[tex]g(-x)=-g(x)[/tex]

(a)

Let f and t are both even functions, then

[tex]f(-x)=f(x)[/tex]

[tex]t(-x)=t(x)[/tex]

The product of both functions is

[tex]ft(x)=f(x)t(x)[/tex]

[tex]ft(-x)=f(-x)t(-x)[/tex]

[tex]ft(-x)=f(x)t(x)[/tex]

[tex]ft(-x)=ft(x)[/tex]

The function ft is even function.

(b)

Let f and t are both odd functions, then

[tex]f(-x)=-f(x)[/tex]

[tex]t(-x)=-t(x)[/tex]

The product of both functions is

[tex]ft(x)=f(x)t(x)[/tex]

[tex]ft(-x)=f(-x)t(-x)[/tex]

[tex]ft(-x)=[-f(x)][-t(x)][/tex]

[tex]ft(-x)=ft(x)[/tex]

The function ft is even function.

(c)

Let f is even and t odd function, then

[tex]f(-x)=f(x)[/tex]

[tex]t(-x)=-t(x)[/tex]

The product of both functions is

[tex]ft(x)=f(x)t(x)[/tex]

[tex]ft(-x)=f(-x)t(-x)[/tex]

[tex]ft(-x)=[f(x)][-t(x)][/tex]

[tex]ft(-x)=-ft(x)[/tex]

The function ft is odd function.
