solve The quantity 2 x minus 10 divided by 4 = 3x

Answers

I assume you mean:

(2x-10)/4=3x  multiply both sides by 4

2x-10=12x  subtract 12x from both sides

-10x-10=0  add 10 to both sides

-10x=10  divide both sides by -10

x=-1

To solve the equation 2x - 10 / 4 = 3x, multiply both sides by 4, simplify, and solve for x to find its value as -1.

Step 1: Multiply both sides of the equation by 4 to get rid of the fraction:
4 * (2x - 10) / 4 = 4 * 3x

Step 2: Simplify the equation:
2x - 10 = 12x

Step 3: Rearrange the equation to solve for x:
2x - 12x = 10
-10x = 10
x = -1

Because the car that has a terrible oil leak not only as a new battery for the van but also slows him down because he needs the Atwell after every hundred miles of driving he drives 100 miles every two hours it takes him 15 minutes to add oil how long should it take him to drive 500 miles

Answers

11 hours and 15 minutes to drive 500 miles

To drive 500 miles, taking into account both driving time and oil stop time, it would take 11 hours and 15 minutes.

He drives 100 miles every 2 hours, so to drive 500 miles he would take 10 hours (5 segments of 100 miles each).He needs to add oil every 100 miles, which takes 15 minutes each time. Therefore, for the 500-mile trip, he would spend an additional 75 minutes (5 segments x 15 minutes each).Adding the driving time and oil stop time, he would take 10 hours (driving) + 1 hour 15 minutes (oil stops) = 11 hours 15 minutes to drive 500 miles.

What is the degree of each monomial -9

Answers

The degree of a monomial is the sum of the exponents of the variables.

For example:

monomial: 257 x^3 y^5 z^21.

The degree is the sum of the exponents of x, y and z, this is 3 + 5 + 21 = 29.

When a monomial is just a number, it means that the exponents of the variables are zero. For example:

- 9 x^0 y^0 z^0 = - 9 * 1 * 1 * 1 = - 9.

This is your case, the monomial -9 has degree 0, which is the option B.

What is the distance between the points (3,8) (-9,8)

A)5
B)10
C)15
D)20

Answers

This one is easier than normal because the y coordinates are the same.
So the distance is simply 3 - -9 = 12.

So all answers are wrong or you made a typo!
Final answer:

The distance between the points (3,8) and (-9,8) is 12. The correct answer is option B) 10.

Explanation:

The distance between two points can be found using the distance formula: d = √((x2 - x1)^2 + (y2 - y1)^2). In this case, the coordinates of the two points are (3,8) and (-9,8). Plugging these values into the formula, we get:

d = √((-9 - 3)^2 + (8 - 8)^2)
d = √((-12)^2 + (0)^2)
d = √(144 + 0)
d = √144
d = 12

Therefore, the distance between the points (3,8) and (-9,8) is 12. The correct answer is option B) 10

An acute angle θ is in a right triangle with sin θ = two thirds . What is the value of cot θ?

Answers

check the picture below.

Answer:

six divided by the square root of thirteen

Step-by-step explanation:

hey there,

< sin θ = [tex]\frac{O}{H}[/tex]

So that means O = 2 and H = 3. In order to find cot θ, first let's find tan θ.

tan θ = [tex]\frac{O}{B}[/tex]

We only know what O is equal to, not B. So let's draw out a triangle.

7  

◢   6

 B

As you can see (sorry for the poor triangle), this is a right triangle. In order to find an unknown part, use [tex]a^2 + b^2 = c^2[/tex]!

[tex]6^2 + B^2 = 7^2[/tex]

B = ±√13

Obviously, a side of a triangle can't be negative, so it stays positive. Now we can find tangent!

tanθ =  [tex]\frac{6}{\sqrt{13} }[/tex]

But, we're not done here. We're trying to find cotθ.

cotθ = [tex]\frac{1}{tan}[/tex]θ

[tex]\frac{1}{\frac{6}{\sqrt{13} } }[/tex] = [tex]\frac{\sqrt{13} }{6}[/tex]

Bella made a drawing of her rectangular bedroom with the scale of 1 inch = 3 feet. The drawing was 6 inches long by 4 inches wide. What are the dimensions of Bella's room? What is the actual area? Show your work.

Answers

3x6=18 3x4=12 12+18=30 so the actual area is 30

Bella's actual room dimensions are 18 feet by 12 feet, resulting in an actual area of 216 square feet. This was determined by applying the scale factor from the drawing to the actual room size.

To determine the actual dimensions of Bella's room based on her drawing, we first need to use the provided scale factor. According to the scale, 1 inch on the drawing is equal to 3 feet in actual size. We can calculate the actual dimensions by multiplying the length and width of the drawing by the scale factor.

The drawing is 6 inches long by 4 inches wide.

Actual length: 6 inches × 3 feet/inch = 18 feet

Actual width: 4 inches × 3 feet/inch = 12 feet

Now, to determine the actual area of Bella's room, we multiply the actual length by the actual width:

Actual area = actual length × actual width

Actual area = 18 feet × 12 feet = 216 square feet

Use the distributive property to expand the following expression. -3(6.3x + 7y - 2.5)

Answers

The expression -3(6.3x + 7y - 2.5) expands to -18.9x - 21y + 7.5 using the distributive property by multiplying each term inside the parentheses by -3.

To use the distributive property to expand the expression -3(6.3x + 7y - 2.5), you multiply each term inside the parentheses by -3. The distributive property lets you reverse the distributive law and turn it into factors (multiples).

-3 × 6.3x = -18.9x
-3 × 7y = -21y
-3 ×-2.5 = 7.5

Once each term is multiplied, the expanded expression is:   -18.9x - 21y + 7.5

For a daily airline flight between two cities, the number of pieces of checked luggage has a mean of 380 and a standard deviation of 20. What number of pieces of checked luggage is 3 standard deviations above the mean?

Answers

Since one standard deviation is 20 luggages, 3 standard deviations above the mean is 3*20=60 luggages above the mean of 380 luggages, so 60+380 gives the answer C, 440.

Answer:

The answer is 440 pieces of checked luggage

Step-by-step explanation:

Mean = 380

Standard deviation = 20

No. of pieces of checked luggage for 1 standard deviation = 20 pieces

Therefore, Mean for 3 standard deviations above the mean = 3 × 20 = 60

Now, number of pieces of checked luggage 3 standard deviations above the mean = Mean for 1 standard deviation + Mean for 3 standard deviations above the mean

⇒ 380 + 60 = 440 pieces

una pizzeria hace pizzas de varios tamaños y las vende en cajas hexagonales de 39 cm de lado y 4.7 cm de alto ¿que cantidad de cartón se anestesia para cada caja teniendo en cuenta q la caja esta formado por dos partes compuestas de una base lateral ?

Answers

Final answer:

To calculate the amount of cardboard used for each box, we need to find the surface area of the hexagonal base and the lateral surface area. We can use the formula for the surface area of a hexagon to find the base area. Then, we multiply it by the height of the box and add the two areas together.

Explanation:

To find the amount of cardboard used for each box, we need to calculate the surface area of the hexagonal base and the lateral surface area. The surface area of a hexagon can be found using the formula:

Surface Area = 3 x √3 x s^2

where s is the length of the side of the hexagon. Given that the side length is 39 cm, we can substitute this into the formula to find the surface area of the hexagonal base. Once we have the surface area, we can calculate the lateral surface area by multiplying it by the height of the box, which is 4.7 cm. Adding the two areas together will give us the total amount of cardboard used for each box.

A permutation is defined as a mathematical process that determines the number of different arrangements in a set of objects when the order of the sequential arrangements.

There are 10 options for each of the 5 digits in the personal identification code (0 through 9). Since the order of the digits matters, we can use the formula for the number of permutations of n items taken r at a time, which is:

n!/(n-r)!

In this case, n is the number of options (10) and r is the number of items (5). Plugging these values into the formula gives us:

10!/(10-5)! = 10!/(5!) = 109876 = 30,240

Therefore, the correct answer is (d) 30,240.

A coin is tossed 72 times. Find the standard deviation for the number of heads that will be tossed

Answers

The probability of obtaining a head or tail in tossing a coin is modeled by the binomial distribution.

The probability of obtaining heads (success) is p = 1/2.
In n tosses, the expected statistical parameters are
m = np, the mean
σ = √[np(1-p)]

In 72 tosses of the coin, the standard deviation for the number of heads obtained is
σ = √[72*(0.5)*(0.5)]
   = 4.243

Answer: 4.243

The standard deviation for the number of heads that will be tossed is [tex]\boxed{4.24}.[/tex]

Further Explanation:

The random variable X follows binomial distribution.

[tex]\boxed{X \sim {\text{Bin}}\left( {n,p} \right)}[/tex]

Here, n represents the total number of experiments and p denotes the probability of the event.

Apply central limit theorem.

[tex]\boxed{X \sim {\text{Normal}}\left( {np,np\left( {1 - p} \right)} \right)}[/tex]

The mean of the binomial distribution can be calculated as follows,

[tex]\boxed{{\text{Mean}} = n \times p}[/tex]

The standard deviation of binomial distribution can be calculated as follows,

[tex]\boxed{{\text{Standard deviation}} = \sqrt {np\left( {1 - p} \right)} }[/tex]

Given:

Coin is tossed 72 times.

Explanation:

Consider X is the random variable that head will occur.

The probability of head occur is [tex]p = \dfrac{1}{2}.[/tex]

The mean can be calculated as follows,

[tex]\begin{aligned}{\text{Mean}}&= 72\times \frac{1}{2}\\&= 36\\\end{aligned}[/tex]

The standard deviation of the number of heads can be calculated as follows,

[tex]\begin{aligned}{\text{Standard deviation}}&= \sqrt {72 \times \frac{1}{2}\left( {1 - \frac{1}{2}} \right)} \\&= \sqrt {72 \times\frac{1}{2} \times \frac{1}{2}}\\&=\sqrt{\frac{{72}}{4}}\\&= \sqrt {18}\\&= 4.24\\\end{aligned}[/tex]

Hence, the standard deviation for the number of heads that will be tossed is [tex]\boxed{4.24}.[/tex]

Sasha sets a goal to read 5 minutes longer than each previous day for 30 days. On the first day, Sasha reads for 20 minutes. The expression mc018-1.jpg represents the total number of minutes Sasha reads during the 30 days. How many total minutes does she read?

Answers

Final answer:

Sasha reads a total of 2775 minutes over 30 days, calculated using the formula for the sum of an arithmetic sequence.

Explanation:

To calculate the total number of minutes Sasha reads over 30 days, we note that she starts with 20 minutes on the first day and reads 5 minutes more each subsequent day. This is an arithmetic sequence where the first term (a1) is 20 minutes, the common difference (d) is 5 minutes, and the number of terms (n) is 30.

We can use the formula for the sum of an arithmetic sequence: Sn = n/2 (2a1 + (n - 1)d).

Plugging in the given values gives us S30 = 30/2 (2(20) + (30 - 1)(5)).

Now we calculate: S30 = 15(40 + 29(5)) = 15(40 + 145) = 15(185) = 2775 minutes.

Therefore, Sasha reads a total of 2775 minutes over the course of 30 days.
