what are three equations that are equivalent to 60% of 25
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:
Distribute the coefficients Combine any like term on both side.Arrange the term in same order.If all the terms in two expressions are same then the equations are equivalent.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

what is the area of the largest rectangle with lower base on the x axis and upper vertices on the curve y
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.

a worn, poorly set-up machine is observed to produce components whose length x follows a normal distribution with mean 14 centimeters and standard deviation 3 centimeters. find the probability that the length of a component lies between 19 and 21 centimeters. round your answer to four decimal places.
The probability that the length of a component lies between 19 and 21 centimeters is 0.0376.
What is probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Given:
Population mean, µ = 14
Population standard deviation, σ = 3
Probability that the length of a component lies between 19 and 21 centimeters
= P(19 < X < 21)
= P( (19 - 14) / 3 < (X - µ) / σ < (21 - 14) / 3)
= P(1.67 < z < 2.33)
= P(z < 2.33) - P(z < 1.67)
Using excel function:
= NORM.S.DIST(2.33,1) - NORM.S.DIST(1.67,1)
= 0.9901 - 0.9525
= 0.0376
Hence, the probability that the length of a component lies between 19 and 21 centimeters is 0.0376.

Last year, Pinwheel Industries introduced a new toy. It cost $2500 to develop the toy and S25 to manufacture each toy. Fill in the blanks below as appropriate.
A.) Give a linear equation in the form Cmn + b that gives the total cost, C, to produce n of these toys Preview
B.) The total cost to produce n 3000 toys is S
C.) With $32500, a total of toys can be produced.
a)The linear equation is C=25n + 2500 to produce n 3000 toys, b) The total cost to produce 3000 toys is $77,500, c) With $32500, a total of 1200 toys can be produced in Pinwheel Industries.
What is meant by the term linear equation?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
C= 25(3000) + 2500
C= $77,500
C)

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one

quadrilateral abcd is a rhombus with perimeter 52 meter. the length of diagonal ac is 24. what is the are in square meters of rhombus abcd?
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.

if an open rectangular box is to have a fixed volume v, what relative dimensions will make the surface area a maximum
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.

Monica says that she will earn more interest in one year because her interest rate is higher, is she correct? justify your response.
Paul earns more interest than Monica does.
What is simple interest?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.
