How to turn 2.087 into a fraction

The volume of the stone if, The volume of the water is 110 cm³, and The volume of the water and the stone is 150 cm³, is 40 cm³.

The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.

Given:

The volume of the water = 110 cm³,

The volume of the water and the stone = 150 cm³,

Calculate the volume of the stone as shown below,

The volume of stone = The volume of the water and the stone - The volume of the water

The volume of stone = 150 - 110

The volume of stone = 40

Thus, the volume of the stone is 40 cm³

The width of the rectangle is 5 units.

The length must be 6 units to have an area of 30 square units.

Points C and D must be 6 units below points A and B.

The two linear functions have the same y-intercept. Then the correct option is A.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

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

The function 3x + 2y = 8 and the other function is graphed.

Convert the standard linear function into slope-intercept form. Then we have

3x + 2y = 8

2y = 8 - 3x

y = 4 - (3/2)x

The y-intercept of the linear function is 4 and the y-intercept of the graphed line is also 4.

The two capabilities have a similar y-catch. Then, at that point, the right choice is A.

Every ideal of S is principal when f:R⇒S be a surjective homomorphism of rings with identity.

In a homomorphism, corresponding elements of two systems behave very similarly in combination with other corresponding elements. For example, let G and H be groups. The elements of G are denoted g, g′,…, and they are subject to some operation ⊕.

In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). The word homomorphism comes from the Ancient

Let f:R⇒S be a surjective homomorphism of rings with identity.

We have to find if R is a PID, prove that every ideal in S is principal.

We know that,

Let I be the ideal of S

Since f is sufficient homomorphism.

So, f⁻¹(I) is an ideal of R.

Since R is PID so ∈ r ∈ R such that

f⁻¹(I) = <r>

I = <f(r)>

Therefore,

Answer:

m<P = 31°

Step-by-step explanation:

Use this symbol < for angle, not <.

<P and <Q are complementary.

That means that their measures add to 90°.

m<P + m<Q = 90°

Now we substitute 7x + 3 for m<P and 16x - 5 for m<Q.

7x + 3 + 16x - 5 = 90

Solve for x.

23x - 2 = 90

23x = 92

x = 4

m<P = 7x + 3 = 7 × 4 + 3 = 31

Answer:

x = 1

Step-by-step explanation:

y = 9 is a horizontal line. It intersects the y axis at (0,9) and for all value s of x, y = 9.

Therefore a line perpendicular to this line will be of the form x = k where k is some constant. It means that for all values of y, the x value is constant. The y value is irrelevant

Since the line passes through (1,-1), ie through x = 1, y = -1, the equation of the line is x = 1

As the point moves along the helix, it traces out a three-dimensional surface in space.The space curve would look like a helix in graph.

1. First, we need to find the vector-valued function r(t) using the given parameter.

2. We can use the parameter x+z=2 to solve for the y-coordinate in terms of t:

y = √(4 − (1+sin t)2 − (1 − sin t)2).

3. We can now substitute this expression into the vector-valued function to obtain:

r(t) = (1+sin t)i+ (√(4 − (1+sin t)2 − (1 − sin t)2))j+ (1-sin)k

4. The space curve represented by the intersection of the surfaces is a helix in a graph.

The space curve represented by the intersection of the surfaces is a helix. It is a three-dimensional curve that can be described by a vector-valued function r(t) with parameter t. The vector-valued function r(t) is given by:

r(t) = (1+sin t)i+ (√(4 − (1+sin t)2 − (1 − sin t)2))j+ (1-sin)k.

The helix can be visualized as a spiral that wraps around a cylinder and is generated by a point travelling around the circumference of the cylinder at a constant speed. This can be observed by noting that the x- and z-coordinates of the vector-valued function are constant and only the y-coordinate changes over time. As the point moves along the helix, it traces out a three-dimensional surface in space.

It is false that the probability of an individual from this population will have a weight greater than 72 pounds is 0.31 instead it is 0.70

According to the question,

Weight of population follows normal distribution

Mean of population : u = 75 pounds

Population Standard deviation : σ = 5.9 pounds

We have to Check if the probability an individual from this population will have a weight greater than 72 pounds is 0.31

Probability that weight is greater than 72 = P( x > 72)

Subtracting by 75 both sides and then dividing by 5.9

=> P( x - 75 / 5.9 > 72 - 75 / 5.9)

Using Z-statistics,

=> P( z > -3/5.9)

=> P( z > -0.508)

=> 1 - P(z < -0.50)

Using Probability distribution table for z,

=> 1 -  0.305

Coefficient Cn is determined by Cn = 1/2 ∫[0,2] (x+2)yn(x) dx

To find the coefficients Cn of the eigenfunction expansion of a function f(x), f(x) must be expanded with the eigenfunction yn(x). The expansion of f(x) with respect to the eigenfunction yn(x) is given by

f(x) = Σ[∞], n=1 cnyn(x)

To find the coefficient cn, we need to compute the dot product of f(x) and yn(x).

cn = (f,yn) = ∫[0,4]f(x)yn(x)dx

Since the eigenfunctions yn(x) are orthonormal, the scalar product is given by

cn = ∫[0,4]f(x)yn(x)dx = ∫[0,2]f(x)yn(x)dx + ∫[2,4]f(x)yn(x)dx

Since f(x) = 2/2 x for x in [0,2] and f(x) = 2 for x in [2,4], compute the coefficient cn as I can do it.

cn = ∫[0,2](2/2x)yn(x)dx + ∫[2,4](2)yn(x)dx

= ∫[0,2]xyn(x)dx + ∫[2,4]2yn(x)dx

= 1/2 ∫[0,2] (xyn(x) + 2yn(x)) dx

= 1/2 ∫[0,2] (x+2)yn(x) dx

A system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased is; 300a + 450b = 6000 and a + 5 = b.

The variables x and y respectively represents  cans of soup and frozen dinners and a and b represents number of cans of soup and frozen dinners.

Let cans of soup be denoted by x

Let each frozen dinner be denoted by y

Now, we are told that each can of soup has 300 mg of sodium and each frozen dinner has 450 mg. Thus;

x = 300

y = 450

It is said that Samuel purchased 5 more frozen dinners than cans of soup  and they all collectively contain 6000 mg of sodium.

Let the no. of cans of soup be 'a' and no. of frozen dinner be 'b'. Thus, we will have the equation as;

Answer:

We can solve this problem using the elimination method, and in the elimination method we need to change equations so that one of the variables (either x or y) is eliminated. to do this, we can multiply one or both of the equations by constants so that the coefficients of one of the variables becomes equal so we can eliminate it from the equation. This will allow us to add the equations together and eliminate that variable.

For example, we could multiply the first equation by -5 and the second equation by 6, to get:

-30x + 10y = -20

-30x + 48y = 270

Then, we can add these equations together to eliminate the x variable:

-30x + 10y = -20

-30x + 48y = 270

-60x + 58y = 250

We can then solve for y by dividing both sides of the equation by 58:

y = 250 / 58

y = approximately 4.31

Once we have the value of y, we can substitute it back into one of the original equations to solve for x. for example, if we substitute it into the first equation, we get:

6x + 2 * 4.31 = 4

6x = 4 - 8.62

6x = -4.62

x = -0.77

Therefore, the solution to the system of equations is x = -0.77 and y = 4.31.

The general anti derivative or indefinite integral of the function

cos2x - sec²x is 1/2 sin2x + tan x + C .

The given function is of the form : cos2x - sec²x

Now we will use the indefinite integral on the above expression:

∫cos2x - sec²x

This can be broken into :

∫cos2x -  ∫sec²x

Now we will integrate them separately:

∫cos2x, we will use u-substitution.

Let 2x = u

Differentiation both sides we get:

2 dx = du

or, dx = 1/2 du

Hence we will use this value:

∫cos2x

Again we will do the second part of the integral:

∫sec²x

Hence the required integral will be:

1/2 sin2x + tan x + C .

Now we will use differentiation to check the integral
