The mass of the cylindrical clay pipe is 16.54 kg if the 2 m length of cylindrical clay pipe of external and internal diameters 15 cm and 12 cm.

<h3>What is density?</h3>

It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol ρ The density is measured in kilograms per cubic meter.

We have:

2 m length of cylindrical clay pipe of external and internal diameters 15 cm and 12 cm.

The volume of the pipe:

= Volume of the cylinder(D = 15 cm)—Volume of the cylinder (D = 12 cm)

= \rm  \pi (15/2)^2 (200) - \rm  \pi (12/2)^2 (200)

Because 2 meters = 200 cm


= 35342.91 - 22619.46

= 12723.45 cubic cm

Density = mass/volume

1.3 = mass/12723.45

mass = 16540.48 g ≈ 16.54 kg

Thus, the mass of the cylindrical clay pipe is 16.54 kg if the 2 m length of cylindrical clay pipe of external and internal diameters 15 cm and 12 cm.

Which part of the cell holds genetic information in the molecule DNA?
crimeas [40]

Answer:

The correct option is Chromosomes.

Step-by-step explanation:

The correct option is Chromosomes.

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus. Chromosomes are not visible, not even under a microscope. However the DNA becomes more tightly packed during the cell division and is then visible under a microscope.

Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections...

The scale of this map is 1 inch = 50 miles. The ruler measures the distance between Gary, Indiana, and Traverse City, Michigan,
levacccp [35]

Answer:

<em>150 miles</em>

Step-by-step explanation:

Given the scale on the map using the conversion factor

1 inch = 50 miles

We are to find the equivalent miles between the cities in miles if the distace is 3inches

3inches = x

Divide both expressions

1/3 = 50/x

Cross multiply

x = 3 * 50

x = 150

<em>Hence the actual distance between these two cities in miles is 150 miles </em>

2. If f(x) = x - 7 and g(x) = 2x + 5, then what is f(x) * g(x)?
AysviL [449]

Answer:

2x² - 9x - 35

Step-by-step explanation:

f(x) × g(x) = (x - 7)(2x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 5) - 7(2x + 5) ← distribute both parenthesis

= 2x² + 5x - 14x - 35 ← collect like terms

= 2x² - 9x - 35
