The density of the material is  0.4 kg/cubic cm.

Given that:-

Height of the cylinder = 54.5 mm

Diameter of the cylinder = 53.0 mm

Weight of the cylinder = 1 kg

We have to find the density of the cylinder.

We know that,

Density  = mass/volume

Here, mass = 1 kg

We know that,

Volume of a cylinder = [tex]\frac{1}{3} \pi r^2 h[/tex]

Where,

r is the radius of the cylinder, and

h is the height of the cylinder

Here, h = 54.5 mm, and

r = 53/2 = 26.5 mm

Hence,

Volume of cylinder = (1/3)*(22/7)*(26.5)(26.5)*54.5 ≈ 2566.088 ≈ 2566 cubic mm. = 2566/(10*10*10) cubic cm = 2.566 cubic cm

Density of cylinder = 1kg/2.566 cubic cm  ≈ 0.3897  ≈ 0.4 kg/cubic cm.

Answer:

Step-by-step explanation:

the diagonal is the hypotenuse of the two triangles that form the rectangle (see figure) we solve with Pythagoras

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

a² = b²+ c²

a² = 250² + 190²

a² = 62500 + 36100

a² = 98600

a = √98600

a = 314 m

Answer:   w > 50

This is because we are focusing on weights (w) that are larger than 50

We won't have an "or equal to" as part of this.

An inequality for the given scenario is;

⇒ w > 50

Here,

The given scenario is;

For safety, all dogs at a dog park who weigh, w, more than 50 pounds must play in Area 2.

We have to find the inequality.

A scatter plot is a series of points plotted on horizontal and vertical axes. If there is no correlation between variables, the points appear randomly scattered on the coordinate plane. The points will be clustered around a straight line if the correlation is high. A scatter chart is a data visualization tool that helps show trends.

The scatter plot shows not only the magnitude of the correlation but also the direction of the correlation.

As the vertical (or Y-axis) variable increases, the correlation is positive as the horizontal (or X-axis) variable increases.

The correlation is negative if the y-axis variable decreases and the x-axis variable increases, or vice versa.

The correlation is zero if none of the above criteria can be established.

The circumference of the children's ball to the nearest centimeter is 52 centimeters.

If a regulation volleyball has a circumference of about 66 centimeters, solve for its radius using the formula for the circumference of a circle given by:

C = 2πr

66 centimeters = 2πr

r = 33/π centimeters

Then, solve for the surface area of this regulation volleyball using the formula given by:

A = 4πr^2

A = 4π(33/π centimeters)^2

A = 4356/π square centimeters

If the ratio of the surface area of that ball to the surface area of a children's ball is approximately 1.6 : 1, then

surface area of regulation volleyball : surface area of a children's ball = 1.6 : 1

surface area of a children's ball = 4356/π square centimeters/1.6

surface area of a children's ball = 2722.5/π square centimeters

If  the children's ball has a surface area of 2722.5/π square centimeters, solve for its radius using the formula for the surface area given by:

A = 4πr^2

2722.5/π square centimeters = 4πr^2

r = 26.0887907/π centimeters

Solving for the circumference:

C = 2πr

C = 2π(26.0887907/π centimeters)

C = 52.17758139 centimeters

The discriminant of the quadratic equation is q · (q + 8) < 0. The solution set of this inequality is (0, - 8).

The nature of the roots of quadratic equations of the form a · x² + b · x + c = 0 can be inferred by the understading of its discriminant under the following condition:

b² - 4 · a · c < 0

Where a, b, c are the coefficients of the polynomial.

If we know that a = 2 · q, b = q and c = - 1, then the equation of the discriminant is:

q² - 4 · (2 · q) · (- 1) < 0

q² + 8 · q < 0

And by algebraic handling, we find the set of possible values of q:

Interest is Rs.96  and Total amount payback is Rs.3096.

Principal (P) = Rs.3000

Rate of  interest (R) = 1.6%

Number of years (N) = 2 yrs

Simple interest = PNR/100

= (3000*1.6*2)/100

=(9600/100

=96Rs

Total Amount (A) = P+I

=3000+96

=3096Rs

The principal, or initial balance of your account, is where interest is calculated. This could be the initial sum of a loan or an investment. The simplest way to compute interest is as a percentage of the principal .Only relatively short-term loans frequently include one-time basic interest charges. Interest is frequently paid on a daily, monthly, quarterly, or annual basis for loans with longer terms. In that scenario, interest would be consistently earned.

Hence, the interest for the above principle is 96Rs and the total amount to be payback is 3096Rs.

An equiangular triangle is also an example of an acute triangle is a True statement.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

An equiangular triangle is a triangle whose all angles are the same and since all angles are the same so by geometrical constraint all sides must be the same so it will also be an equilateral triangle.

In an equilateral triangle, all interior angles are 60°, and since an acute angle triangle is a triangle in which all angles must be less than 90°.

So an equiangular triangle will be an acute triangle.

= 80 ÷ 40

= 2

Step-by-step explanation:

f(x) = 5|x - 1| - 5

f(x) will be positive that means >= 0, if

5|x - 1| - 5 >= 0

5|x - 1| >= 5

|x - 1| >= 1

that will be true for x <= 0 or x >= 2

f(x) will be negative for the other cases.

so, 0 < x < 2

f(x) is increasing in

[1, infinity)

the value "1" is for sure included, as it starts the increasing part.

f(x) is decreasing in

(-infinity, 1]

"1" is again included, because it ends the decreasing part.

end behavior means for x going to infinity and -infinity : in both cases f(x) goes to infinity.
