density = <u>mass</u>

                volume

= <u>     40kg      </u>    =     <u>40kg</u>

5m x 8m x 3m  =    120cubic metres

= <u>1/3 kg per cubic m or 0.33 kg per cubic m</u>

Find the area of this circle use 3.14 or 22/7 or pie round your answer to the nearest hundred if necessary
notka56 [123]

Answer:

The area of the circle is 50.24 mm ²

Step-by-step explanation:

To solve this exercise we need to use the area formula of a circle:

a = area

r = radius = 4mm

π = pi = 3.14

a = π * r²

a = 3.14 * (4mm )²

a = 3.14 * 16mm ²

a = 50.24 mm ²

The area of the circle is 50.24 mm ²

Members of Alachua District Choir were asked, when given the choice between Romanticism or Gothic
zalisa [80]

Answer:

\begin{array}{cccc}{} & {Romanticism} & {Gothic} & {Total} & {Males} & {48} & {63} & {111}& {Females} & {59} & {62} & {121} & {Total} & {107} & {125} & {232} \ \end{array}

Step-by-step explanation:

Given

Romanticism

Male = 48

Female = 59

Gothic

Male = 63

Female = 62

Required

Complete the table <em>(See attachment for complete question)</em>

The table can be represented as:

\begin{array}{cccc}{} & {Romanticism} & {Gothic} & {Total} & {Males} & {48} & {63} & {111}& {Females} & {59} & {62} & {121} & {Total} & {107} & {125} & {232} \ \end{array}

The "total" column represents the number of males and female sampled, respectively.

Male = 48 + 63 = 111

Female = 59 + 62 = 121

The "total" row represents the number of Romanticism and Gothic sampled, respectively.

Romanticism = 48 + 59 = 107

Gothic = 63 + 62 = 125

The overall sample is calculated by adding up the number of males and females or the number of Romanticism and Gothic

Overall = Male + Female

Overall = 111 + 121 = 232

or

Overall = Romanticism + Gothic

Overall = 107 + 125 = 232

Look at the graph shown<br> Which equation best represents the line?
Brilliant_brown [7]

y=\frac{11}{4}x +4 is the equation best represents the line.

Solution:

Take any two points on the line.

Let the points be (0, –4) and (4, 7).

x_1=0,y_1=-4,x_2=4, y_2=7

General form of equation of a line is y = mx + c

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

<em>y-intercept is the point which line crosses at y-axis.</em>

In the given line, y-intercept is 4.

c = 4

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{7-(-4)}{4-0}

$m=\frac{11}{4}

Equation of the line:

y = mx + c

y=\frac{11}{4}x +4

Hence y=\frac{11}{4}x +4 is the equation best represents the line.
