How to calculate area of rectangle ?

The area of a rectangle is equal to its length times its width. Follow the steps mentioned below to find the area of a rectangle:

Step 1: Note the dimensions of length and breadth from the given data.

Step 2: Find the product of length and breadth values.

Step 3: Give the answer in square units.

Given :

Area = 40x.6y.9z

length of one side = 10 x ³y ³

∵Area of rectangle = length ˣ breadth

∴ 40x.6y.9z  = 10 x ³y ³  × length of other side

length of other side =  [tex]\frac{40x.6y.9z}{10 x^{3} y^{3} } = 4x^{-2} . 6y^{-2} . 9z[/tex]

Hence , the length of the other side is  4x⁻².6y⁻².9z .

The equation of a parabola with a directrix at y = −3 and a focus at (5, 3) is y=1/12(x - 5)² .

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

Given that the directrix of parabola is at y=-3.

Focus at (5, 3)

parabola with equation  (x - h)² = 4p(y - k)

p = 3 because the distance from the focus to the directrix is 6 and p = 6/2.

The vertex (5, 0)

Substitute h as 5 and k as 0.

(x - 5)² = 4(3)(y - 0)

(x - 5)² = 12y

Divide both sides by 12

y=1/12(x - 5)²

Hence,  the equation of a parabola with a directrix at y = −3 and a focus at (5, 3) is y=1/12(x - 5)² .

Three easy actions must be taken in order to describe this system as a matrix:

First, create a matrix with all the coefficients. An acronym for this is a coefficient matrix.

Multiply this matrix by the system setup's variables in another matrix.

In another matrix, place the solutions on the other side of the equal sign.

The aggregate volume of the two rectangular prisms is 330 cubic cm.

The base's area multiplied by the height gives the rectangular prism its volume. So the formula for a rectangular prism's volume is as follows. Using cubic units, the volume of a rectangular prism = length × breadth × height

The volume is going to be the addition of two volumes.

We are going to divide the shape into two.

Volume = length × breadth × height

Section A and section B

Volume = length × breadth × height

Volume of section A is = 2 × 10 × 9

Volume of section A = 180 cm³

Volume = length × breadth × height

Volume of section B is = 3 × 5 × 10

Volume of section B = 150cm³

Total volume = volume of section A + volume of section B

Total volume = 180cm³ + 150cm³

Total volume = 330cm³

Answer:

write the given equation in a standard form

6x - 2y = 6

-2y = -6x + 6

y = 3x - 3

m = 3

if the lines are perpendicular to each other the product of their gradient is equal to -1

m1 × m2 = -1

3 × m = -1

3m = -1

m = -1/3

y - y1 = m(x - x1 )

y - (-1) = -1/3 ( x - (-3) )

y + 1 = -1/3 (x + 3 )

y + 1 = -1/3x - 1

y = -1/3x - 1 + 1

y = -1/3x

Answer:

y = -8x + 10.

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -8 and the y-intercept is (0, 10), so the equation is y = -8x + 10.

The equation of a line is given by y = mx + c

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 120.

The slope of a line that passes through (4,440) and (6,560) is 0.676.

We have,

The equation of the line y = mx + c.

The line passes through (4,440) and (6,560).

This means,

We can find the slope using the coordinates (4,440) and (6,560).

Slope = m

m = (4,440) / (6,560)

m = 0.676

Answer:

The first expression, (5^2*x^6*y^(-7))(5*x^0*y^28)

Step-by-step explanation:

Basically, add up the exponents for each unique base. We have two exponents with bases of 5 in this expression, 5^2 and 5 (which is equal to 5^1). Add the exponents together to get 3, so you have 5^3 = 125.

Add up the exponents for bases of x this time. We have x^6 and x^0. 6 + 0 = 6, so we have x^6.

Finally add up the exponents for bases of y. We have y^28 + y^(-7) = 28 + (-7) = 21, so we have y^21.

The gross pay of worker this week is $432.325

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Number of money made in one hour = $ 14.35

Number of hours, worked on Monday = 8 hours

Number of hours, worked on Tuesday = 1/2 hours

Number of hours, worked on Wednesday = 8¾ hours

Number of hours, worked on Thursday = 4 hours

Number of hours, worked on Friday = 8¼ hours

Total number of worked = 4 + 8 + 8¼ + 8¾ + 1/2

                                             = 29.5

Total gross pay = 14.35 × 29.5

Use dimensions of the rectangle to find its area:

What is dimension?

A database of research grants called Dimensions connects funding to publications, clinical trials, and patents as well as other outcomes. Dimensions is a part of the technology firm Digital Science, which has its global headquarters in London, United Kingdom.

Given:

The dimensions of each room are,

Living room = 20 ft x 15 ft

Kitchen = 12 ft x 10 ft

Bedroom 1 = 12 ft x 12 ft

Bedroom 2 = 12 ft x 10 ft

Bathroom = 8ft x 12 ft

So, the total square footage is,

(20 + 12 + 12 + 12 + 8) ft x (15 + 10 + 12 + 10 + 12) ft = 64 ft x 59 ft = 3776 square feet.

Hence, the total square footage of the house is 3776 square feet.

The addition equation is 93 - 67 = 26 in the number line.

What is number line?

A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.

The entire question is depicted in the picture that is attached.

Richard added 26 to 67 by first marking point 67 on the line, then adding 2 tens and 2 threes until he reached 93 as opposed to subtracting 67 to 93 by subtracting 6 tens and 7 ones starting at point 93, which results in 26.

Take note that 26 is equal to 10 plus 10 plus three additional times.

To verify his work, we add the following: 67 + 26 = 93, which is also written as 93 - 67 = 26.

Hence the addition equation is 93 - 67 = 26.

The value of n after solving the given equation comes to 75.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation.

A variable, coefficients, and constants make up an algebraic equation in most cases.

So, we have the equation:

n/(200 - n) = 3/5

Now, solve for x as follows:

n/(200 - n) = 3/5

5n = 600 - 3n

8n = 600

n = 600/8

n = 75

Therefore, the value of n after solving the given equation comes to 75.
