55 miles per hour is equivalent to 24.6992 meters per second.

Translate milles to meter / second?

To convert miles per hour (mph) to meters per second (m/s), you can use the conversion factor 1 mile = 1609.34 meters.

To convert miles per hour (mph) to meters per second (m/s), you can use the conversion factor 1 mph = 0.44704 m/s.

So to convert 55 mph to m/s, you can multiply 55 by 0.44704:

55 mph * 0.44704 m/s/mph = 24.6992 m/s

Therefore, 55 miles per hour is equivalent to 24.6992 meters per second.

The space dedicated to growing beans is 4 ft.

"AB || CD" and "CD || EF" mean that lines AB and CD are parallel and lines CD and EF are parallel as well. Since lines AB and EF are parallel and the length of line CD is 6 ft, the length of line AB and line EF is also 6 ft.

From the information given, we can see that the space dedicated to growing beans is the distance between lines CD and EF.

We also know that the space dedicated to growing beets is 3ft, and the space dedicated to growing celery is 2ft.

Therefore, we can subtract 3ft + 2ft from 6ft to find the space dedicated to growing beans: 6ft - 3ft - 2ft = 4ft.

So the answer is 4ft.

Therefore, The space dedicated to growing beans is 4 ft.

Rectangles have the following properties:

A quadrilateral with four right angles is a rectangle. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.

A rectangle's opposite sides are the same length (congruent). A rectangle's angles are all congruent (the same size and measure.) The term "right angle" refers to an angle that is 90 degrees or more. A rectangle therefore has four right angles. A rectangle's opposing angles are congruent.

Step-by-step explanation:

The width of rectangle is 10 units.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Perimeter of rectangle = 116 units

let the width be x.

then the length is 5x - 2.

so, Perimeter of rectangle = 116 units

2 (5x -2 + x)= 116

2(6x - 2) = 116

6x - 2 = 58

6x = 60

x= 10

So, the width is 10 units and length is 5(10)-2 = 48 units

When the parent graph of the equation, y = √x is changed to y = -√x + 1, the following statements are true:

B. shift down one unit.

C. reflect over the x-axis.

In Mathematics, the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image or function.

Next, we would translate the parent graph of the equation down by one unit;

y = √x - (k)

y = √x - (-1)

y = √x + 1

In Geometry, a reflection over the x-axis is given by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over the x-axis would maintain the same x-coordinate while the sign of the y-coordinate changes from positive to negative or negative to positive.

Lastly, we would apply a reflection over the y-axis;

(x, y)     →     (x, -y)

y = -(√x + 1)

Using Sabah's function, ($1125, $500) is the right ordered pair. It is not a function if any of the x values are the same, but this is not true if the y values are different.

A set of ordered pairs is not a function if an x value has more than one y value associated with it. For instance, in the relation (4, 1), (4, 2), the x-value of 4 has y-values of 1 and 2, indicating that this relation is not a function. The connection is a function if each x-value has a single corresponding y-value.

An ordered group of pairs makes up a relation (x, y). A pair that has two values stated in a specific order between parenthesis is known as an ordered pair. It is made up of the x coordinate (abscissa) and the y coordinate (ordinate). For greater visual comprehension, it helps to locate a point on the Cartesian plane.

The derivative of 7e to the 7x is 7e to the 7x * 7ln(e) * 7. The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x.

1. Take the natural logarithm of the base: ln(e7x)

2. Take the derivative of the natural logarithm: 7x*ln(e)

3. Apply the chain rule: 7e7x * 7ln(e) * 7

The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x. The natural logarithm of e7x is ln(e7x). Taking the derivative of the natural logarithm yields 7x*ln(e). We then apply the chain rule to get the final result of 7e7x * 7ln(e) * 7. In other words, the derivative of 7e to the 7x is equal to 7 multiplied by e raised to the 7x power, multiplied by 7ln(e), and then multiplied by 7 once more.

The time required for the new guy to finish the car is given by the equation A = 10/3 hours = 3 1/3 hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the time required for the new guy to finish the car be A

Now , the equation will be

The total time worked by the two mechanics = 2 hours

The time for the 1st person to finish the car = 6 hours

So , the amount of work done in 2 hours by 1st person = 2/6 = 1/3 of total

The time for the 2nd person to finish the car = 8 hours

So , the amount of work done in 2 hours by 2nd person = 2/8 = 1/4 of total

And , the remaining work = 1 - ( 1/3 + 1/4 )

On simplifying the equation , we get

The remaining work = 1 - ( 7/12 ) = 5/12 of the work

Now , the time required for the 2nd person to complete 5/12 of the work =

A = 5/12 x 8

A = 5 x 2/3

A = 10/3

A = 3 1/3 hours = 3 hours and 20 minutes
