-x=-6 what is X is it 6 or -6?

Answers

Answer:

Step-by-step explanation:

It may be confusing to see why it would 6 instead of -6. The missing value in the X already includes the negative symbol. So if the 6 was the X value, then the negative sign would apply to the 6 making it - 6. The results would be:

⇒ $-x = -6$

⇒ $-6=-6$

Answer: the answer is that it takes 15 minutes to fill the tank per 1 meter.

Step-by-step explanation:

You have to divide 2/5 by 6 to find the answer. 6/1 divided by 2/5 equals 6/1 x 5/2, which equals 30/2. 30/2 equals 15. Hope this helps!

2/5 = 6 mins so 1/5 is 3 mins. 3x5 = 15 mins 5/5 = 15 mins

4j + 5 = 147
4j = 142
142 ÷ 4 = 35.5

So j = 35.5

Answer:

f(x)=4x

Step-by-step explanation:

Let's look at the progression of f(x) values as the x value goes up. The x value goes up in steps of 1, but the f(x) value goes up in steps of 4. This means that the f(x) value grows 4 times faster than the x value. Comparing them side by side, you can see that each f(x) value is indeed 4 times larger than the corresponding x value. Therefore, the descriptive function is f(x)=4x.

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

The equation of a plane which passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5) is given by?

Answers

Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

Please help i give brainliest, show the work though. Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.

Answers

Answer: 5 1/2 pies as a mixed number, 11/2 as an improper fraction, 5.5 as a decimal, 550 as a percent

Step-by-step explanation:

2x5+1 11

-----------= -----

2 2

The fraction 5 1/2 is equal to 5, plus 1 divided by 2 which is equal to 5, plus 0.5 which is equal to 5.5 in decimal

5.5 x 100 = 550 percent

Mixed fraction:

Given statement: Susan is buying 5 and a half pies from the market.

We already know:

The word "and" means "in addition to", which means addition (+)

Therefore, the number of pies Susan bought is;

⇒ 5 and a half pies⇒ 5 + half pies

∴ Half can be written as ½

⇒ 5 + ½

If a whole number is being added to a fraction, we can combine them to convert the sum into mixed fraction.

⇒ 5 + ½⇒ 5 ½

Therefore, 5 ½ is the fraction of pies, Susan bought.

Improper fraction:

Given statement: Susan is buying 5 and a half pies from the market.

In mixed fraction: Susan is buying 5 ½ pies from the market.

To convert the mixed fraction of pies into improper fraction, simply multiply the whole number by the denominator and add the numerator to the product of the whole number and the denominator. The denominator in the mixed fraction will remain the same in the denominator.

⇒ 5 ½⇒ [(5 × 2) + 1]/2⇒ [(10) + 1]/2⇒ [11]/2 = 11/2

Therefore, 11/2 is the fraction of pies, Susan bought.

Decimal:

Given statement: Susan is buying 5 and a half pies from the market.

In improper fraction: Susan is buying 11/2 pies from the market.

Clearly, we can rewrite 11/2 as;

⇒ 10/2 + 1/2

10/2 results in getting 5 and 1/2 results in getting 0.5. Therefore,

⇒ 5 + 0.5⇒ 5.5

Therefore, 5.5 is the decimal of pies, Susan bought.

Percent:

Given statement: Susan is buying 5 and a half pies from the market.

In decimal: Susan is buying 5.5 pies from the market.

Simply multiply the decimal by 100 to determine the percentage of pies bought by Susan.

⇒ 5.5 pies = 5.5 x 100% = 550%

Therefore, 550% is the percent of pies, Susan bought.

Formula of change: amount of change/ original amount *100.

Answer: The percentage change is 16%.

Step-by-step explanation:

February:

4,100 water bottles.

March:

(4,100 + 7/100 x 4,100) water bottles

(4,100 + 287) water bottles.

4,387 water bottles.

April:

(500 + 4,387) water bottles.

4,887 water bottles.

= (4,887 - 4,100) / 4,887 x 100

= 787/4,887 x 100

= 16%

The percentage change is 16%.

B; Student B because it requires a hypothesis
C: Student A because it is preferably done in natural settings
D: Student B because it is preferably done across a long period of time

Answers

Answer:

A is the correct answer.

Step-by-step explanation:

In experiment we require a controlled variable which is the constant in example A that is the plant we intend to put into the soil. In example B there's no such thing as controlled variable, so we can't expect the position of the water level. the water level is so unpredictable since tides or tsunami might change the result.

Answer:

Step-by-step explanation:

Scientific experiments need to have an independent and a dependent variable. Scientists can manipulate the independent variable. A should be the correct answer because it mentions what I just said. All scientific experiments need to have a control and experimental group. Therefore, student A and the answer A are correct.

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

Miles per hour

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?

Answers

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

We know that the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:

18 = 2πr

Solving for r, we get:

r = 9/π ≈ 2.864 feet

Now we can use the formula for the area of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(2.864 ft)^2 ≈ 25.85 ft^2

Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).

Scale factor = $2\frac{1}{2}$

Here, N(-4, 6)→(-4, -6)

M(-6, 2)→(-6, -2)

G(-2, 4)→(-2, -4)
