the volume of a soap bubble is 2,308.4 mm ^3. Find the radius and diameter of the soap bubble. Use 3.14 for pi​

Answers

Answer 1

Answer:

r = 8.2mm

d = 816.4mm

Step-by-step explanation:

Let the soap be spherical in nature

Volume of a sphere = 4/3 πr³

r is the radius

Given that V = 2308.4mm^3

Substitute

2308.4 = 4/3 πr³

2308 = 4/3 (3.14)r³

2308.4 * 3 = 12.56r³

6,925.2 = 12.56r³

r³ = 6,925.2 /12.56

r³ = 551.37

r = 8.2mm

diameter = 2r

diameter = 2(8.2)

diameter = 16.4mm

Answer:

£9.00

Step-by-step explanation:

67.00-49.00 = 18.00÷2 = 9.00

Let's Try:

a) 9.00×7 = 63.00+4.00(hat) = 67.00

b) 9.00×5 = 45.00+4.00(hat) = 49.00

Answer:

tshirt equals £9

and hat equals £4

Step-by-step explanation:

7t + h = 67

5t +h  = 49      subtract bottom eq from top

 

2t = 18      t = 9

 

5(t) + h = 49

5(9) + h = 49

45 + h = 49

h = 4                  

Find angle RST
Please help​

Answers

Answer:

62

Step-by-step explanation:

so because the triangle going through the center it classifieds as a right triangle which makes angle SRT = 90 degree

three angle of a triangle add up to 180

so we have SRT + RTS + RST = 180

we have SRT

=> 90 + RTS + RST = 180

=> 90 + (3x -25) + (x - 1 ) = 180

=> 90 + 4x -26 = 180

=> 64 + 4x = 180

=> 4x = 116

=> x = 29

now u have x , just plug in and solve

Answer:

p = -1/5

Step-by-step explanation:

-5p + -15/5 = -4

-5p -3 = -4

-5p = -4 +3

-5p = -1

p = -1/5

Answer:

p = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Given

- 5 (p + [tex]\frac{3}{5}[/tex] ) = - 4 ← distribute parenthesis on left side by - 5

- 5p - 3 = - 4 ( add 3 to both sides )

- 5p = - 1 ( divide both sides by - 5 )

p = [tex]\frac{1}{5}[/tex]

Use slope formula to find the slope:

8-5.5/2-1 = 2.5

therefore the M (slope) is 2.5

Answer:

y = 2.5x + 3

Step-by-step explanation:

y2 - y1/x2 - x1 = slope

5.5 - 3 = 2.5

2 - 1 = 1

2.5/1 = 2.5

8 = 2.5(2) +b
