A graduated cylinder is filled with 20ml of water. Then, an 8g marble is dropped into the cylinder, causing the volume to change
Tema [17]

Answer:

The density of the marble is 2,000 kg/m³

Step-by-step explanation:

The given parameters for finding the density of the marble are;

The volume of water in the graduated cylinder, v₁ = 20 ml

The mass of the marble dropped into the graduated cylinder, m = 8 g

The new volume of the cylinder after the 8 g marble is dropped into the cylinder, v₂ = 24 ml

Therefore, the volume of the marble, v = v₂ - v₁

Substituting the known values gives;

The volume of the marble, v = 24 ml - 20 ml = 4 ml

Density, ρ = Mass, m/(Volume, v), the units of density is kg/m³

Therefore, the density of the marble, \rho _{marble}, is given as follows;

\rho _{marble} = m/v = (8 g)/(4 ml) = 2 g/ml

1 g/ml = 1 kg/l = 1,000 kg/m³

∴ \rho _{marble} = 2 kg/l = 2,000 kg/m³.

"write an expression that evaluates to true if the value of the integer variable x is divisible (with no remainder) by the integ
AysviL [449]

Solution:

As we have to write an expression , which evaluates to true if the value of the integer variable x is divisible (with no remainder) by the integer variable y, y≠0.

so, when x is divided by y we should get remainder as 0.

Using Euclid division lemma

x= y* q + m, i.e when an integer x is divided by y gives quotient q and remainder m.

Here , m=0

So, x = q * y

So, the expression which describes the above relationship is ,

\frac{x}{y}=q, where q is Quotient.

Which point is the incenter of ​ △JKL ​ ?
allsm [11]

Answer: In-center of the triangle is point N.


Step-by-step explanation:

We are given a triangle △JKL.

In triangle △JKL, they drew perpendicular bisectors of each side of the triangle.

Also we are given angle bisectors of the each of angles in given triangle.

Note: Perpendicular bisector is a line that intersect a segment into two equal parts and also perpendicular to it.

<em>Also note that the in-center is the point forming the origin of a circle inscribed inside the triangle. It is constructed by taking the intersection of the angle bisectors of the three vertices of the triangle.</em>

<h3>We can see that angle bisectors are intersecting at a point N. </h3><h3>Therefore, in-center of the triangle is point N.</h3>
