The equation which is equivalent to 60% of 25 is x = 0.6 * 25

1. Equivalent equations: Equivalent equations are algebraic equations that are having identical roots or solutions. By adding or subtracting the same number or expression to both side of an equation we get an equivalent equation. Also by multiplying or dividing both sides of an equation by the same non zero number we get equivalent equation.

2. How to find equivalent equation : Steps to find weather the equations are equivalent are:

An equation is used to show the relationship between variables, numbers.

Let x represent the value of 60% of 25. Hence:

x = 60% of 25

x = 0.6 * 25

Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25

The measure of both the angles will be x = 80° and y = 100°.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. Two lines are said to be parallel if they have same slope. These lines never intersect each other and have no common point of intersection.

Given is the same side interior angles of two parallel lines is 20° less than the other same side interior angles.

Same side interior angles are supplementary, we can write -

x + x + 20 = 180

2x = 160

x = 80°

Other angle will be -

y = x + 20 = 100°

y = 100°

Therefore, the measure of both the angles will be x = 80° and y = 100°.

Relative dimensions which will make the surface area a maximum is

x=y = \sqrt{area/3 }

z = 1/2(  \sqrt{area/3 })

Volume = 2xh

Let the box have dimensions x,y,z>0.

The surface area is A=xy+2xz+2yz

The volume is V=xyz

The Lagrangian is L=V−λ(A−constant)=xyz−λ(xy+2xz+2yz−constant).

∂L∂x=yz−λ(y+2z)=0

∂L∂y=xz−λ(x+2z)=0

∂L∂z=xy−λ(2x+2y)=0

Hence, λ=yzy+2z=xzx+2z=xy2x+2y

On cross multiplication,

xyz+2yz2=xyz+2xz2which implies x=y.

Cross-multiplying the middle and the right expressions ,2x2z+2xyz=x2y+2xyzwhich implies z=12y.

So, optimal volume with fixed surface area is to have the width and the depth equal and the height to be half the width and depth.

To find x,y,z given a fixed surface area Area one would use x=y=2z in the equation

Area=xy+2xz+2yz=x2+x2+x2 so

x=y = \sqrt{area/3 }

z = 1/2(  \sqrt{area/3 })

Volume is a measurement of three-dimensional space that is occupied. Numerous imperial units or SI-derived units, such as the cubic metre and litre, are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship.

4 square units will be the area of the largest rectangle.

Given,

First, let's build a rectangle ABCD, where A is the point at the bottom right corner and B,C, and D are the points designated in accordance with A.

Now,

Let A = (p, 0)

B = (-p, 0)

C = (-p, 3 - p²)

D = (p, 3 - p²)

Then the area of rectangle is given as: BA×AD

= 2p × 3 - p²

A = 6p - 2p³

Taking the derivative with respect to p, we have

A' = 6 - 6p²

Now,

A' =0

⇒ 6 - 6p² = 0

⇒ 6p² = 6

⇒ p² = 1

Since, we have to find the greater area, therefore we will take p = 1.

Now, substituting the value of p in (A), we have

Greater area = A= 6 - 2 x 1 = 4 square units

Therefore,

The  area of the largest rectangle should be 4 square units.

What is outfits?

A group of clothes that have been specifically chosen or designed to be worn together is known as an outfit. The term "outfit" can also refer to a business, an association, or a team of people who collaborate frequently. It can be used as a verb to mean "provide with the necessary gear."

A dress is different from a blouse and a skirt!  So I'll rephrase this as how many ways can she dress, to wear one blouse, one skirt and one pair of matching shoes.

You just multiply the number of blouses, the number of skirts, and the number of pairs of shoes;

Step-by-step explanation:

The area of the Rhombus ABCD is 1.2 square meter.

What is Rhombus?

A quadrilateral with four equal-length sides is known as a Rhombus in plane Euclidean geometry. Another name for this shape is an equilateral quadrilateral because all of its sides are equal in length.

Let ABCD be the given Rhombus of Perimeter = 52 cm.

Since all the sides are equal to each other.

Therefore, each side of Rhombus measures = 13 cm

So,

AD = CD = 13 cm and AC = 24 cm.

Area of the triangle ACD = √[ s (s - a) (s - c) (s - d) ] ….. Heron’s Formula.

where s = semi-perimeter,

a, c, and d are side measures.

s = (1/2) [ 13 + 13 + 24 ] = 25

Area (A) = √[ 25 (25 – 13) (25 – 13) (25 - 24) ] = 60

Hence Area of the entire Rhombus = 2 * 60 = 120 cm²

Convert 120 cm^2 into meter square

⇒ 120 cm^2 = 1.2 m^2

Hence, the area of the Rhombus ABCD is 1.2 square meter.

An equation is a mathematical statement with an equal symbol (=) between the algebraic expression. Equations with a degree of one are called linear equations. It is the straight line's equation. Whenever values are substituted for the unknown values in linear equations, the solutions produce values that make the equation true. Since there is only one variable, there is only one solution. For instance, the equation x + 2 = 0 has just one solution, which is x = -2. In the case of the two-variable linear equation, however, the solutions are determined as the Cartesian coordinates of a point on the Euclidean plane.

The three different types of linear equations are: 1) Standard Form

2) The slope intercept form

3)Point Slope Form

How to solve?

A) Linear equation y=mx+b,

C (total cost) = y and n (number of toys) =x.

C=25n + 2500

B) Put n=1750

Differentiation reverses the parity of a function, means if f(x), is an even function, then its derivative f'( x ) is odd which is true i.e f(x) is even function implies f'(x) is odd and if f(x) is odd function implies f'(x) is even .

First, let's we start with the definition of even and odd functions.

f is even if and only if f(x) = f(-x) --(1)

f is odd iff f(x) = -f(-x) ---(2)

If f is even and differentiating equation (1) we get,

f'(x) = f'(-x)× (-1) = -f'(-x).

f'(x) = - f'(-x).

Since, f'(x) is some function, then let

g(x) = f'(x) So, we see g(x) = -g(-x) which shows that the derivative of an even function is an odd function.

If f is odd then: f(x) = -f(-x)

differentiating above function with respect to x we get ,

f'(x) = -f'(-x)× (-1 ) = f'(-x).

Let g(x) = f'(x), then g(x) = g(-x) which shows that the derivative of an odd function is an even function.

Hence, Differentiation reverses the parity is hold.

Paul earns more interest than Monica does.

Simple interest can be defined as a form of interest in which the percent rate is applied on the same principal for a given period of time.

Given that,

Money deposited by Monica is $200 at simple interest of 3.7%.

Money deposited by Paul is $300 at simple interest of 2.9%.

The expression to calculate simple interest is given as,

(P × r × t)/100

Substitute the corresponding values to obtain the simple interest for both cases as follows,

Interest gained by Monica is (200 × 3.7 × 1)/100 = $7.4.

Interest gained by Paul is (300 × 2.9 × 1)/100 = $8.7.

Hence, monica is not correct as the interest earned by Paul is greater than that of monica.
