41 minutes

When 9 people are painting 9 walls, there are the same amounts of people and walls.  This means all of the walls are being painted at the same time, with one person painting each wall.

The same applies to 14 people painting 14 walls.  All of the walls are being painted at the same time, with one person painting each wall.

Even if there was only one person painting one wall, it would take 41 minutes.

Answer:

41 minutes

Step-by-step explanation:

It takes 41 minutes for 9 people to paint 9 walls.

9 walls/ 9 people = 1 wall / person

So it takes 41 minutes  for 1 person to paint 1 wall

14 walls/ 14 people = 1 wall / person

It will take the same amount of time

41 minutes

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

We have the slope m = 2 and the y-intercept b = 0. Substitute:

y = 2x + 0 = 2x

Answer:  The correct option is (C) [tex]y=2x.[/tex]

Step-by-step explanation:  We are given that the slope of a line is 2 and the y-intercept is 0.

We are to find the equation of the line written in the slope-intercept form.

The equation of a line in slope-intercept form is given by

[tex]y=mx+c,[/tex] where m is the slope and c is the y-intercept of the line.

For the given line, we have

slope, m = 2   and   y-intercept, c = 0.

Therefore, the equation of the line in slope-intercept form will be

[tex]y=mx+c\\\\\Rightarrow y=2\times x+0\\\\\Rightarrow y=2x.[/tex]

Thus, the required equation of the line in slope-intercept form is [tex]y=2x.[/tex]

Option (C) is CORRECT.

Answer:

8cm

Step-by-step explanation:

Ab=7cm

Since opposite sides are equal

Cd=7cm

7cm + 7cm = 14cm

Perimeter equals 30cm

:.30cm - 14cm =16cm (bc+ad)

Since both bc and ad are equal,

16cm/2=8cm

:.ad=8cm

Final answer:

In a parallelogram, opposite sides are equal, so by using the given perimeter of 30 cm and one side of 7 cm, we find the length of the adjacent side AD to be 8 cm.

Explanation:

In the given problem with parallelogram ABCD, we know AB = 7 cm and the perimeter is 30 cm. In a parallelogram, opposite sides are equal in length, so if AB = 7 cm, then CD also equals 7 cm. The perimeter P of a parallelogram is the sum of all its sides:

P = AB + BC + CD + DA

Given P = 30 cm and AB = CD = 7 cm, we can find the length of AD (which is also equal to BC) using the formula:

P = 2(AB + AD)

30 = 2(7 + AD)

30 = 14 + 2(AD)

30 - 14 = 2(AD)

16 = 2(AD)

AD = 16 / 2 = 8 cm

Therefore, the length of AD is 8 cm.

x y^2 (11 x y - 4)

Step-by-step explanation:

Simplify the following:

4 x^2 y^3 + 2 x y^2 - 2 y - (-7 x^2 y^3 + 6 x y^2 - 2 y)

Factor y out of -7 x^2 y^3 + 6 x y^2 - 2 y:

4 x^2 y^3 + 2 x y^2 - 2 y - y (-7 x^2 y^2 + 6 x y - 2)

-y (-2 + 6 x y - 7 x^2 y^2) = 2 y - 6 x y^2 + 7 x^2 y^3:

4 x^2 y^3 + 2 x y^2 - 2 y + 2 y - 6 x y^2 + 7 x^2 y^3

Grouping like terms, 4 x^2 y^3 + 2 x y^2 - 2 y + 2 y - 6 x y^2 + 7 x^2 y^3 = (4 x^2 y^3 + 7 x^2 y^3) + (2 x y^2 - 6 x y^2) + (2 y - 2 y):

(4 x^2 y^3 + 7 x^2 y^3) + (2 x y^2 - 6 x y^2) + (2 y - 2 y)

x^2 y^3 4 + x^2 y^3 7 = 11 x^2 y^3:

11 x^2 y^3 + (2 x y^2 - 6 x y^2) + (2 y - 2 y)

x y^2 2 + x y^2 (-6) = -4 x y^2:

11 x^2 y^3 + -4 x y^2 + (2 y - 2 y)

2 y - 2 y = 0:

11 x^2 y^3 - 4 x y^2

Factor x y^2 out of 11 x^2 y^3 - 4 x y^2:

Answer:  x y^2 (11 x y - 4)

Answer:  xy2 • (11xy - 4)

Step-by-step explanation:

4 x^2 y^3 + 2 x y^2 - 2 y - (-7 x^2 y^3 + 6 x y^2 - 2 y)

Factor y out of -7 x^2 y^3 + 6 x y^2 - 2 y:

4 x^2 y^3 + 2 x y^2 - 2 y - y (-7 x^2 y^2 + 6 x y - 2)

-y (-2 + 6 x y - 7 x^2 y^2) = 2 y - 6 x y^2 + 7 x^2 y^3:

4 x^2 y^3 + 2 x y^2 - 2 y + 2 y - 6 x y^2 + 7 x^2 y^3

Grouping like terms, 4 x^2 y^3 + 2 x y^2 - 2 y + 2 y - 6 x y^2 + 7 x^2 y^3 = (4 x^2 y^3 + 7 x^2 y^3) + (2 x y^2 - 6 x y^2) + (2 y - 2 y):

(4 x^2 y^3 + 7 x^2 y^3) + (2 x y^2 - 6 x y^2) + (2 y - 2 y)

x^2 y^3 4 + x^2 y^3 7 = 11 x^2 y^3:

11 x^2 y^3 + (2 x y^2 - 6 x y^2) + (2 y - 2 y)

x y^2 2 + x y^2 (-6) = -4 x y^2:

11 x^2 y^3 + -4 x y^2 + (2 y - 2 y)

2 y - 2 y = 0:

11 x^2 y^3 - 4 x y^2

Factor x y^2 out of 11 x^2 y^3 - 4 x y^2:

Answer:  x y^2 (11 x y - 4)

Step-by-step explanation:

-52-1x= 9(x+9)+9x

-1x= 18x+81

            -52

-1x=18x+29

-1x=29

+18x

17x= 29

      ÷17

x=1.705

Answer:

The answer is....

Step-by-step explanation:

y= -10x+400

Follow below steps:

The student's question involves writing a linear function for the height of an elevator as a function of time, given that the elevator descends from 400 feet to 250 feet in 15 seconds.

First, let's find the rate of descent by calculating the change in height over the change in time. This gives us (250 feet - 400 feet) / (15 seconds) = -10 feet per second. The negative sign indicates a downward movement.

Now, we can construct the linear function for height h(t), where t is the time in seconds. The initial height is 400 feet, so the y-intercept of our linear equation is 400. With a slope of -10, the function takes the form:

h(t) = -10t + 400

This function represents the height of the elevator after t seconds.

Answer:

9/5 is 4 over 1 so you would have 1 and add 4 on and since it is out of 9 it would be 1 4/5

Step-by-step explanation:

The mixed fraction  [tex]1 \frac{4}{5}[/tex] after solving gives the value of the fraction as 9/5.

A fraction represents a part of a number or any number of equal parts.

There is a fraction, containing a numerator(upper value) and denominator(lower value). A proper fraction is also called a fraction that is less than 1. A mixed fraction contains a sum of a whole number and a proper fraction.

We know that 9/5 is 4 over 1

Therefore, we would have 1 and add 4 on.

Since it is out of 9 then it would be [tex]1 \frac{4}{5}[/tex]

Hence, the mixed fraction  [tex]1 \frac{4}{5}[/tex] after solving gives the value of the fraction as 9/5.

Answer: 4

Step-by-step explanation: To have an equation with no solution you have to get something like 0=1 meaning you have to remove all the variables. In this equation you would distribute to get xy+2y+2x=2x+12+4x where y is the missing number. then combining like terms you get xy+2x+2y=6x+12. Subtracting 2x from both sides you get xy+2y=4x+12. Now to get the variables gone y has to be 4 so that the variables to cancel out. By plugging in 4 you can see this works; 4x+8=4x+12 and by subtracting 4x from both sides you get 8=12 which is not true meaning there is no solution.

Answer:

The difference in elevation is 7,716 ft

Step-by-step explanation:

Let

y -----> the elevation of Mt Owens

x -----> the elevation of the bolo cavern

we know that

To find the difference in elevation between the bolo cavern and Mt Owens, subtract the elevation of the bolo cavern from the elevation of Mt Owens

we have

y=7,295 ft ----> is positive because is above sea level

x=-421 ft ----> is negative because is below sea level

therefore

y-x=7,295-(-421)=7,295+421=7,716 ft

Final answer:

To determine the difference in elevation between Bolo Cavern and Mt. Owens, add the absolute values of their elevations: 421 feet below sea level and 7295 feet above sea level, respectively, resulting in a difference of 7716 feet.

Explanation:

The question asks for the difference in elevation between the Bolo Cavern, which is 421 feet below sea level, and Mt. Owens, which is 7295 feet above sea level. To find the difference in elevation, we add the absolute values of both elevations together since one is below sea level and the other is above.

The elevation of the Bolo Cavern is -421 feet (below sea level), and the elevation of Mt. Owens is +7295 feet (above sea level). The difference in elevation is:

|-421| + |7295| = 421 + 7295 = 7716 feet.

Therefore, the difference in elevation between the Bolo Cavern and Mt. Owens is 7716 feet.

Step-by-step explanation:

Given the 2 equations

5x + y = 21 → (1)

x - 3y = 9 → (2)

Multiply (1) by 3 and add the result to (2) to eliminate y term

15x + 3y = 63 → (3)

Answer: [tex]x^{\frac{2}{3} }[/tex]

Step-by-step explanation:

We have several properties of exponents in use here. The two that are used are:

[tex](x^{a})(x^{b}) = x^{a + b}[/tex] (Exponents with the same base that are being multiplied together can have the exponents added)

[tex](x^{a})^{b} = x^{(a)(b)}[/tex] (A base raised to a power, and then raised to another power means that you can multiply the exponents to get the same result as doing inside operations and then outside operations)

Let's apply it!

First, let's simplify what's inside the parenthesis.

[tex]x^{\frac{4}{3} } x^{\frac{2}{3} }[/tex] (Remember, they have the same base of "x", so we can add the exponents)

[tex]x^{\frac{4}{3} + \frac{2}{3} }[/tex] = [tex]x^{\frac{6}{3} }[/tex] = [tex]x^{2}[/tex]

Now we have [tex](x^{2})^{\frac{1}{3} }[/tex]. Let's use the second rule.

[tex](x^{2})^{\frac{1}{3} }[/tex] = [tex]x^{\frac{2}{3} }[/tex]

Final answer:

The solution to the inequality -x > 4 is all real numbers less than -4, which can be expressed as the interval (-∞, -4). This is found by dividing both sides by -1 and reversing the inequality to x < -4.

Explanation:

When considering the inequality -x > 4, we are trying to find the set of all values for the variable x that make the inequality true. The solution to such an inequality requires inverse operations and understanding the rules for inequalities, especially the rule that multiplying or dividing both sides of an inequality by a negative number reverses the inequality symbol.

Step by step, let's solve the given inequality:

This means that any number lower than -4 will be a valid solution for the inequality -x > 4. It's also valuable to visualize this set on a number line, where everything to the left of -4 (but not including -4 itself) is part of the solution set.
