What is an equation?

A mathematical statement called an equation demonstrates the equality of two mathematical expressions.

Based on the given condition of a question,

Let X be the required time duration, and then the equation will be

or, (48+6X)=(72+4X)

or, 48+6X=72+4X

or, 6X-4X=72-48

or, 2X=24

or, X=24/2

or, X=12 year

And height = 48 + 6*12 = 48 + 72 = 120 inches

Hence, In 12 years the two trees will be at the same height of 120 inches.

Answer:

  4.05 pounds

Step-by-step explanation:

You want to know the weight that can be added to 2.65 pounds and 10.8 pounds if the total is to be 17.5 pounds.

The available capacity is the difference between the capacity and the weight already in the container:

  17.5 lb -2.65 lb -10.8 lb = 4.05 lb

The container can hold up to 4.05 more pounds.

The coordinates of the square be

A (0, 0)

B (a, 0)

C (a, a)

D (0, a)

slope of line AC = 1

Slope is the rate of change of the line AC this is solved by taking the ratio of change in y to change in x

A (0, 0) and C (a, a)

= (0 - a) / (0 - a)

= -a / -a

= 1

Slope of line BD = -1

the product of the slopes

= 1 * -1

= -1

The rate at which the diameter decreases is  -0.16cm/min

Diameter:

In geometry, diameter refers the straight line that goes from one side to the other side of a circle, passing through the center.

Given,

Here we need to find if a snowball melts so that its surface area decreases at a rate of 1cm^2/min, find the rate at which the diameter decreases when the diameter is 10 cm. Finish solving the problem. Write an equation that relates the quantities.

Here  we obtained the equation that relates the surface area S and the diameter D of a sphere given by

=> S = πD²

Now, we have differentiate the equation as,

=> dS/dt = d/dt (πD²)

=> dS/dt = π d/dt (D²)

​=> dS/dt = 2πD dD/dt

Now, Solving for dD/dt, which is the unknown for this problem, we have

=> dD/dt ​= 1/2πD​ x dS​/dt

Now, substituting the given values, the rate of change of the diameter when D=10 cm and dS/dt as (-1) is

=> dD/dt = 1/2 x π x 10 (-1)

=> dD/dt = -1/20π

=> dD/dt = -0.16cm/min

And we want to solve this by substitution, first, we can rewrite the first equation as:

-3x + 3*(2y) = 12

Now we can substitute the second equation 2y = x + 4 in the parenthesis, we will get:

-3x + 3*(x + 4) = 12

Now we can solve this for x.

The inverse of a function is f^-1(x) = 3(x + 17)/2 and f^-1(x) = x + 10

What is function ?

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable).

An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.

Functions can be roughly categorized into four sorts. based on the element Numerous to one function, onto function, one to one and onto function, into function.

1.f(x) = 2x/3 - 17

Finding the inverse

y = f(x)

  = 2x / 3 - 17

Exchange the variables, x for y and y for x

x = 2y / 3 - 17

Isolate the variable y

Adds 17 both sides

x + 17 = 2y / 3

Multiply by 3 both sides

3(x+17) = 2y

Divide by 2 both sides

y = 3(x + 17)/2

let f^-1(x) = y

f^-1(x) = 3(x + 17)/2

2. f(x) = x - 10

Finding the inverse

y = f(x)

  = x - 10

Exchange the variables, x for y and y for x

x = y - 10

Isolate the variable y

Adds 10 both sides

y = x + 10

Multiply by 3 both sides

3(x+17) = 2y

The tangent theta is a Trigonometric function, the simplified value of 1 + tan²θ is sec²θ.

Trigonometric functions are also called circular functions. They are easily defined as functions of triangle angles. This means that the relationships between the angles and sides of triangles are given by these trigonometric functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant. Also read the triangle identity here.

We have given an expression, 1 + tan²θ

we know that , tanθ = sinθ /cosθ

sin²θ + cos²θ =1 and 1/cosθ = secθ

Now, 1 + tan²θ = 1 + sin²θ/cos²θ

taking LCM cos²θ

=> 1 + tan²θ = (cos²θ + sin²θ )/cos²θ

=> 1 + tan²θ = 1/cos²θ

=> 1 + tan²θ = sec²θ

Hence, the required expression is sec²θ.

The area of trapezoid is 7725 ft²

What is a trapezoid?

In American and Canadian English, a quadrilateral with at least one pair of parallel sides is referred to as a trapezoid. It is referred to as a trapezium in British and other varieties of English.

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases. Unlike the specific situations below, a scalene trapezoid is a trapezoid that lacks equal-sized sides.

Given, the expression for the area a is given as

a = [(b₁ + b₂)/2]*h

where b₁ = 125ft, b₂ = 81ft, h = 75ft.

Substituting these values in the above area expression, we get,

a = [(125+81)/2]*75

a = 103*75

a = 7725 ft²

Thus, the area of trapezoid is 7725 ft²

The number of rolls of a fair six sided die will be  1/6.

A cube (plural "cubes") is a solid with marks on each face. Since the faces are usually all of the same shape, the dual of the Platonic solids and the Archimedean solids is a natural choice. You can "roll" a die by throwing it in the air and letting it rest on one of its faces. Dice are used in many games to choose random numbers to bet on, and are used in board and role-playing games to determine how many squares to move, the outcome of a competition, etc. Coins are a degenerate two-sided case of dice.

In probability theory, an outcome is the possible outcome of an experiment or trial. Each possible outcome of a given experiment is unique, and different outcomes are mutually exclusive (only one outcome occurs in each trial of the experiment). All possible outcomes of an experiment form an element of sample space.

According to the question,

When a dice is thrown, number of possible outcomes =

1, 2, 3, 4, 5, 6 = 6 = n

If they keep running at the same pace, they will eventually meet at the same end of the course after 30 minutes.

The rate at which distance and time change is what is meant by speed. It has the aspect of temporal and spatial distance. The basic unit of distance with the basic unit of time are combined to form the SI unit of speed. This means that the SI unit of speed is the metre per second.

The way that the issue is described is vague.

I believe what is being said here is that they continue to jog at the same speed.

Half a mile per ten minutes is Diane's speed.

2/3 miles per 10 minutes is Jack's speed.

The numerator and denominator (top and bottom of the ratio) must be multiplied by the factor between 10 minutes and an hour (60 minutes) in order to convert this to a standard miles per hour format.

60/10 = 6.

In order to convert the above speeds to miles per hour, we must multiply both speeds by 6.

Diane: (1/3 divided by 6)/hour equals 2 miles/hour

Jack: (4 miles per hour) = (2/3 x 6) / hour

Diane will complete one length in the time it takes Jack to complete a round trip (back) because he runs twice as fast as she does.

Running a mile at a speed of two miles per hour takes Diane 30 minutes.

Running 2 miles (back and forth) at a speed of 4 miles per hour will take Jack 30 minutes.

We know very well that if a triangle is a right angled it means that  Pythagorean Theorem is applicable on it.

Pythagorean Theorem states that if a triangle is right angled then the sum of square of two sides which are originating from that angle which is 90 degree is equal to square of third side.

In other words,a²+b²=c² where a and b are two sides originating from 90 degree angle and c is the third side which is opposite of the 90 degree angle.

Now, we have a=14 and b=19cm,we need to find value of c.

The composite numbers are exactly the numbers that are not prime and not a unit, since every positive integer is either composite, prime, or the number 1.

Because it is the result of the two smaller integers 2 and 7, for instance, the number 14 is a composite number. The integers 2 and 3 are also not composite numbers because they can only be divided by one another and themselves.
