Answer:

x = [tex]\frac{J-Hy}{G}[/tex]

Step-by-step explanation:

This question is from the topic subject of formula. It implies expressing x in terms of G, H y and J.

Given that: Gx + Hy = J

Subtract Hy from both sides to have;

Gx + Hy - Hy = J - Hy

⇒  Gx = J - Hy

Then divide both sides by G, so that we have;

x = [tex]\frac{J-Hy}{G}[/tex]

Therefore,

x = [tex]\frac{J-Hy}{G}[/tex]

Answer:

The coordinates of B are (5,2).

Step-by-step explanation:

Given that,

The midpoint of AB is M (4,-2).

The coordinates of A are (3,-6)

We need to find the coordinates of B. Let the coordinates of B are (x,y).

The mid point is given by :

[tex]M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})\\\\(4,-2)=(\dfrac{3+x}{2},\dfrac{y-6}{2})\\\\\dfrac{3+x}{2}=4\ \text{and}\ \dfrac{y-6}{2}=-2\\\\3+x=8\ \text{and}\ y-6=-4\\\\x=5,y=2[/tex]

So, the coordinates of B are (5,2).

=================================================================

Explanation:

This is because the value -16 is closest to 0, which represents sea level.

I recommend drawing out a vertical number line. Positive numbers are above 0, to indicate elevations above sea level. Negative numbers represent elevations below sea level.

The diagram is shown below. The diagram is not to scale because the red tickmarks shouldn't be equally spaced out; however, the order is correct, and that's all we need to worry about.

Note how -16 is the highest of the four choices, which makes it the closest to sea level. Also note how as you move further down, the negative values get larger in absolute value. It might be helpful to think of a thermometer.

Answer:

402 mph

Step-by-step explanation:

Draw a right triangle with 400 and 40 as the two legs.

You know this is a right angle because 45 degrees NE is perpendicular to 45 degrees NW. (imagine a compass)

So, the two side lengths are 400 and 40

Using the Pythagorean theorem, (a^2 + b^2 = c^2) you can see that the answer is 401.995, or 402

The ground speed of the plane is 402 mph , Option B is the correct answer.

A right angle triangle is a triangle with one of its sides 90 degree.

It is given that

airplane is travelling at speed of 400mph in the direction N 45° E

wind is blowing at 40 mph in the direction N 45° W

The resultant of these two vectors will be the ground speed of the plane.

As they both are travelling in perpendicular directions ( NE is perpendicular to NW)

A right angled Triangle as attached in the image will be formed

Hypotenuse  by Pythagoras theorem will give the ground speed of the plane

Hypotenuse = [tex]\sqrt { 40 ^2 + 400^2}[/tex]

Hypotenuse = 401.99 mph

Therefore the ground speed of the plane is 402 mph.

Answer:201 11/21

Step-by-step explanation:

The number 4232 is called the numerator or dividend, and the number 21 is called the denominator or divisor.

The quotient of 4232 and 21, the ratio of 4232 and 21, as well as the fraction of 4232 and 21 all mean (almost) the same:

4232 divided by 21, often written as 4232/21.

Read on to find the result of 4232 divided by 21 in decimal notation, along with its properties.We provide you with the result of the division 4232 by 21 straightaway:

4232 divided by 21 = 201.523809

The result of 4232/21 is a non-terminating, repeating decimal. The repeating pattern above, 523809, is called repetend, and denoted overlined with a vinculum.

This notation in parentheses is also common: 4232/21 = 201.(523809): However, in daily use it’s likely you come across the reptend indicated as ellipsis: 4232 / 21 = 201.523809… .

4232 divided by 21 in decimal = 201.523809

4232 divided by 21 in fraction = 4232/21

4232 divided by 21 in percentage = 20152.38095238%

Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 4232 and 21, of course. Repetends, if any, are denoted in ().

The conversion is done automatically once the nominator, e.g. 4232, and the denominator, e.g. 21, have been inserted. No need to press the button, unless you want to start over.

Step-by-step explanation:

Answer:

[tex]area=\frac{85}{4}feet^{2}[/tex]

Step-by-step explanation:

1. Approach

Since it is given that the garden box is a rectangle, then the opposite sides are congruent. One can use this to their advantage, by setting up an equation that enables them to solve for the width of the rectangle. After doing so, one will multiply the width by the given length and solve for the area.

2. Solve for the width

It is given that the garden box is a rectangle. As per its definition, opposite sides in a rectangle are congruent. The problem gives the length and the perimeter of the rectangle, therefore, one can set up an equation and solve for the width.

[tex]perimeter=18\frac{1}{2}\\\\length=5[/tex]

[tex]2(length+width)=perimeter[/tex]

Substitute,

[tex]2(5+width)=18\frac{1}{2}[/tex]

Conver the mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction. Then add the result to the numerator.

[tex]2(5+width)=\frac{37}{2}[/tex]

Inverse operations,

[tex]2(5+width)=\frac{37}{2}\\/2\\\\5+width=\frac{37}{4}\\-5\\\\width=\frac{17}{4}[/tex]

3. Solve for the area

Now that one has solved for the width of the box, one must solve for the area. This can be done by multiplying the length by the width. Since the width is a fraction, one must remember, that when multiplying an integer by a fraction, one will multiply the integer by the numerator (the top of the fraction), and then simplify by reducing the fraction, if possible. Reducing the fraction is when one divides both the numerator and the denominator by the GCF (Greatest Common Factor).

[tex]length=5\\\\width = \frac{17}{4}[/tex]

[tex]length*width=area[/tex]

Substitute,

[tex]5*\frac{17}{4}\\\\=\frac{85}{4}[/tex]

[tex]area=\frac{85}{4}feet^{2}[/tex]

Answer:

The area is 90 sq. cm

Step-by-step explanation:

Given

The variation can be represented as:

[tex]A\ \alpha\ l * w[/tex]

Area = 60, when l = 4 and w = 3

Required

Find Area, when l = 6 and w = 3

Represent the variation as an equation

[tex]A = k(l * w)[/tex]

Where k is the constant of variation.

Substitute 60 for A, 4 for l and 3 for w

[tex]60 = k * (4 * 3)[/tex]

[tex]60 = k * 12[/tex]

Make k the subject

[tex]\frac{60}{12} = k[/tex]

[tex]5=k[/tex]

[tex]k=5[/tex]

To get the value of Area when l = 6 and w = 3.

Substitute 5 for k, 6 for l and 3 for w in [tex]A = k(l * w)[/tex]

[tex]A = 5 * 6 * 3[/tex]

[tex]A = 90[/tex]

The area is 90 sq. cm

Answer:

(y - y') = m ( x - x') [m = slope]

y - (-4) = 2/3 (x - 9)

(y +4) = 2/3 (x - 9)

3(y +4) = 2(x - 9)

3y +12 = 2x - 18

2x - 3y - 18 - 12 =0

2x - 3y - 30 =0

The equation of the line passing through (9, -4) having slope = -2/3 will be y = (-2/3)x + 2

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

y = mx also represents direct proportionality. We can write [m] as -

m = y/x

OR

y₁/x₁ = y₂/x₂

Given is a line passing through (9, -4) having slope=-2/3.

The general equation of a straight line is -

[y] = [m]x + [c]

Now -

m = - 2/3

and

- 4 = -2/3 x 9 + c

- 4 = - 6 + c

c = - 4 + 6

c = 2

The equation will be -

y = (-2/3)x + 2

Therefore, the equation of the line passing through (9, -4) having slope = -2/3 will be y = (-2/3)x + 2
