Find the value of y for a given value of x, if y varies directly with x

Answer: Theater A has the greatest percent of seats filled, at 70%

Step-by-step explanation:

To find out which theater has the greatest percent of its seats filled, we need to calculate the percentage of seats filled in each theater. We can use the following formula to calculate percentage:

Percentage = (Part / Whole) x 100

For theater A, we have 112 seats filled out of 160 total seats: Percentage for theater A = (112 / 160) x 100 = 70%

For theater B, we have 84 seats filled out of 140 total seats: Percentage for theater B = (84 / 140) x 100 = 60%

For theater C, we have 117 seats filled out of 180 total seats: Percentage for theater C = (63 / 180) x 100 = 35% (Note that we need to subtract 63 empty seats from the total seats to get the total filled seats in theater C)

Therefore, theater A has the greatest percent of its seats filled, at 70%.

You can deduct that the height of the first box is 5cm. Since the next box is 3x the size, that means it’s height is 15. So 30*30*15= 13500.

Your answer is 13500 cm^3

Have a blessed day,

Jrodt

Answer:

13500 cm³

Step-by-step explanation:

The linear ratio = 10 : 30 = 1 : 3

The volume ratio = 1³ : 3³ = 1 : 27

Thus the volume of the larger box is 27 times larger than the volume of the smaller box

volume = 500 × 27 = 13500 cm³

Answer:

number of hours  Alexander family ‘s sprinkler work = 20

number of hours  Morgan family ‘s sprinkler work = 30

Step-by-step explanation:

Given in the question,

water output rate for the Alexander family ‘s sprinkler = 40 L  

water output rate for the Morgan family ‘s sprinkler = 20 L

Suppose, number of hours  Alexander family ‘s sprinkler work = x

Suppose, number of hours  Morgan family ‘s sprinkler work = y

Equation1

x + y = 50

Equation 2

40x + 20y = 1400

x = 50 - y

Put this value of x in equation 2

40(50-y) + 20y = 1400

2000 - 40y + 20y = 1400

-20y = 1400 - 2000

-20y = -600

y = 30

Put this value of y in equation 1 to get the value of x

x + 30 = 50

x = 50 - 30

x = 20

Answer:

38 units  

Step-by-step explanation:

Triangle ABC is a right triangle.  To find the missing side, AB (which is the hypotenuse), we use the Pythagorean theorem:

a²+b² = c²

10²+24² = c²

100+576 = c²

676 = c²

Take the square root of both sides:

√(676) = √(c²)

26 = c

AB is a diameter; this means the radius is 26/2 = 13.  This means that OB = 13 and OE = 13.

BD and DE are congruent; this means that BD = 6.

This makes the perimeter

13+13+6+6 = 38 units.

The perimeter of kite OBDE is 38 units.

Pythagoras theorem states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

Perimeter is the distance around the edge of a shape.

A kite is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.

According to the given question.

We have a circle with center o and diameter AB.

Triangle ABC is a right triangle.  

To find the missing side, AB (which is the hypotenuse), we use the Pythagoras theorem.

So,

[tex](AB)^{2} = (10)^{2} +(24)^{2}[/tex]

[tex]\implies (AB)^{2} = 100+ 576\\\implies (AB)^{2} = 676\\\implies AB = \sqrt{676} \\\implies AB = 26[/tex]

Since, AB is the diameter of the circle. Therefore,

[tex]OB = \frac{AB}{2} \\\implies OB = \frac{26}{2} = 13[/tex]

Also, OBDE is a kite and we know that the adjacent sides of a kite are congruent.

[tex]\implies OB = BD = 13 \\\And,\ OE = ED = 6[/tex]

Therefore,

the perimeter of kite OBDE

= Length of sides (OB + BD + DE + EO )

= 13 + 13 + 6 + 6

= 26 + 12

= 38 units.

Hence, the perimeter of kite OBDE is 38 units.

An atom containing two more electrons than protons has a net charge of negative two (-2), as determined by the difference in number of positive protons and negative electrons.

An atom which has two more electrons than protons has a charge of -2. The charge of an atom is determined by the difference between the number of protons and electrons. Protons have a charge of +1 and electrons have a charge of -1. Hence, if the atom has two more electrons than protons, it will have a charge of -2 because electrons contribute a negative charge. For instance, for an atom with 2 protons (+2 charge) and 4 electrons (-4 charge), the overall charge would be -2.

An atom with 2 more electrons than protons will have a net charge of -2.

An atom is the basic unit of matter, consisting of a nucleus containing protons and neutrons, surrounded by electrons. Elements are defined by the number of protons in their atoms. An atom's charge is determined by the difference between the number of electrons and the number of protons. If an atom has 2 more electrons than protons, it will have a net charge of -2.

For example, let's consider the element oxygen (O). Oxygen normally has 8 protons and 8 electrons, resulting in a neutral charge. If we add 2 more electrons to oxygen, it will then have 10 electrons and still 8 protons, giving it a net charge of -2.

Answer:

Hence choice A is correct

Step-by-step explanation:

Given equations are [tex]f(x)=\sqrt{x^2-1}[/tex] and [tex]g(x)=\sqrt{x-1}[/tex]

[tex]\left(\frac{f}{g}\right)\left(x\right)=\sqrt{x+1}[/tex]

Hence choice A is correct

Answer:

a. (f/g)(x) =  √x+1

Step-by-step explanation:

We have given two function.

f(x)  = √x²-1

g(x)  = √x-1

We have to find the quotient of f(x) and g(x).

(f/g)(x) = ?

The formula to find (f/g)(x) is :

(f/g)(x) = f(x) / g(x)

simplifying f(x) , we have

f(x)  = √(x-1)(x+1)

f(x)  = (√x-1)(√x+1)

Putting values in above formula, we have

(f/g)(x) = (√x-1)(√x+1) / √x-1

(f/g)(x) =  √x+1 which is the answer.

Answer: [tex]x=\±2\sqrt{10}[/tex]

Step-by-step explanation:

To find the solutions of the quadratic equation given in the problem, you can apply the proccedure shown below:

- Subtract 40 from both sides of the equation.

- Multiply both sides of the equation by -1

- Apply square root to both sides of the equation.

Therefore, by applyin the steps above, you obtain:

[tex]40-x^2-40=0-40\\-x^2=-40\\(-1)(-x^2)=(-40)(-1)\\\\x^2=40\\\\\sqrt{x^2}=\±\sqrt{40}\\\\x=\±2\sqrt{10}[/tex]

Answer:

= ±2√10

Step-by-step explanation:

40 − x2 = 0

We could solve this by;

subtracting x² from both sides

we get;

40 = x²

Then we get the square root on both sides;

√x² = √40 ; but the square root of a positive number "a" is +√a or -√a

Therefore;

√x² = ± √40

x = ±√40

√40 = √4√10

       = 2√10

Thus;

x = ±2√10

Hence, Graph 1 does not represent the given function.

Graph 2:

when x=1 we have:

[tex]f(x)=1\neq 2[/tex]

Hence, Graph 2 is not the answer.

Graph 4:

when x=1 we have:

Hence, graph 4 is not the correct graph to represent f(x).

Hence, we are left with Graph 3.

Yes, y is a function of x as earnings are proportional to hours worked. The equation describing x as a function of y is x = y/9.60, since Lin's sister earns $9.60 per hour.

The problem states that the amount Lin's sister earns at her part-time job is proportional to the number of hours she works, and she earns $9.60 per hour. To answer the question whether y is a function of x, yes, y is indeed a function of x because for each value of x (number of hours worked), there is exactly one value of y (the earnings).

To write the equation describing x as a function of y, we start with the standard form of the equation for a direct proportion: y = kx, where k is the constant of proportionality. In this case, k is $9.60 per hour. So, the equation would normally be written as y = 9.60x. However, the question asks for x as a function of y. Therefore, we need to rearrange the equation to solve for x: x = y/9.60.

-3 143/1000

Step-by-step explanation:

To write -3.143 in its equivalent fraction form, multiply the whole number part by the place value of the decimal and add it to the decimal part multiplied by the place value. The resulting fraction is -3143/1000.

To write the decimal number -3.143 in its equivalent fraction form, we first need to determine the place value of each digit. The number -3.143 has three digits after the decimal point, so the fraction's denominator will be ten, raised to the power of three, which is 1000. The fraction's numerator will be the whole number part of the decimal (in this case, -3) multiplied by 1000, plus the decimal part (0.143) multiplied by 1000.

Therefore, the equivalent fraction form of -3.143 is:

-3.143 = (-3 * 1000 + 0.143 * 1000) / 1000 = -3143 / 1000

53 degree angle

Step-by-step explanation:

Two angles are said to be complementary if they add up to 90 degrees. Let the complementary angle of 37 degrees is x. These two angles must add up to 90 degrees. So we can set up the equation as:

37 + x  = 90

Subtracting 37 from both sides, we get:

x = 90 - 37

x = 53 degree angle

From the above solution we can see that if we want to find the complementary angle of any angle, we can subtract the given measure from 90 degrees to get our answer.

Answer:53

Answer:

3 meters

Step-by-step explanation:

We assume the storage room is a rectangle, like most rooms, no indication it is otherwise.

We know it's a rectangle and not a square because it is longer than wide.

We have the perimeter measurement (16 meters).

So, we can make the following equation:

2x + 2y = 16

x being the width of the room, y being it's length.  A perimeter is the sum of all sides.

We also know the room is 2 meters longer than wide... so:

y = x + 2

If we replace y in the first equation by its value relative to x, we get:

2x + 2(x + 2) = 16 which becomes

2x + 2x + 4 = 16

4x =12

thus x = 3

Width: 3 meters

Length: 5 meters.

Confirms the 16 meters perimeter.

Answer:

Width = 3 meters

Step-by-step explanation:

We are given that for an equipment storage room, it is 2 meters longer than its width and the perimeter of this room is 16 meters.

Given the above information, we are to find the width of the room.

Perimeter = [tex]2l+2w[/tex]

Supposing [tex]x[/tex] to be the width and [tex]x+2[/tex] to the length, we can write it as:

[tex]16=2(x)+2(x+2)[/tex]

[tex]16=2x+2x+4[/tex]

[tex]12=4x[/tex]

[tex]x=\frac{12}{4}[/tex]

x = 3

Therefore, the width = 3 meters.

- [tex]f(x-a)[/tex] shifts the function, [tex]f(x)[/tex], [tex]a[/tex] units to the right

We can infer from the picture that the blue graph is shifted 2 units to the right of the red graph, so we should apply the second rule:

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

[tex]g(x-2)=(x-2)^2[/tex]
