Plzzzzz answer this question about density mass and volume!!!!!!!!!

nataly862011 [7]

Answer:

13.896 kg

Step-by-step explanation:

You can find the mass of the bar by first finding the volume.

V = BH

where B = area of the base (the trapezium), and

H = height (distance trapezium between bases)

The area of a trapezium is

A = (b1 + b2)h/2

where b1 and b2 are the lengths of the bases of the trapezium (the parallel sides), and

h = the altitude of the trapezium (distance between the bases of the trapezium)

V = (b1 + b2)h/2 * H

V = (12 cm + 6 cm)(5 cm)/2 * 16 cm

V = 720 cm^3

The volume of the bar is 720 cm^3.

Now we use the density and the volume to find the mass.

density = mass/volume

mass = density * volume

mass = 19.3 g/cm^3 * 720 cm^3

mass = 13,896 g

Now we convert grams into kilograms.

1 kg = 1000 g

mass = 13,896 g * (1 kg)/(1000 g)

mass = 13.896 kg

Answer: 1.3896 kg

Answer:

-1 Not in domain

0 In domain

1 In domain

Step-by-step explanation:

The domain for the square root function is all positive numbers including (0). The domain is the set of real numbers which when substituted into the function will produce a real result. While one can substitute a negative number into the square root function and get a result, however, the result will be imaginary. Therefore, the domain for the square root function is all positive numbers. It can simply be expressed with the following inequality:

$x\geq0$

Therefore, one can state the following about the given numbers. Evaluate if the number is greater than or equal to zero, if it is, then it is a part of the domain;

-1 => less than zero; Not in domain

0 => equal to zero; <em> </em>In domain

1 => greater than zero: In domain

There were 150 females surveyed, evenly divided for all levels of expertise. there were 450 males surveyed. there were 80 expert

The values which would help complete the table according to the complete part of the task content are as evaluated.

<h3>What value would help complete the table?</h3>

First, the total number of average players can be evaluated by summing up the total number of players vertically as follows;

180 + average + 80 = 600

The number of average players is therefore; 600-180-80 = 340 average players.

Also, the number of female expert players can be evaluated vertically as;

50 + 50 + female expert = 150

Female expert = 150-50-50 = 50 female experts.

The number of male novice players can be evaluated horizontally as;

Male novice + 50 = 180

Male novice = 180 - 50 = 130.

The number of average male players is therefore easily evaluated vertically as;

130 + male average + 30 = 600

male average = 600-130-30 = 440.

Remarks: The table which is required to be completed is that which is in the attached image.
