Answer:Close to 60 country songs but probably not exactly 60 country songs.

Step-by-step explanation:

Mekala player Jumble has 4 techno songs, 2 country songs, and 3 jazz songs on it.

Represent this songs in ratio format

Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3

Total number of songs is unknowns ,let it be represented by x

total number of songs is therefore 4 x, 2 x, and 3 x.

Total number of songs that Mekala plans to Listen = 2 70

Then , 4 x + 2 x + 3 x= 270

9 x = 270

Dividing both sides by 9, we get

x = 30

So, Number of techno songs = 4 × 30= 120

Number of country songs = 2 × 30= 60

Number of jazz songs = 3 × 30= 90

Which has a greater volume; two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm or one family size can
Sophie [7]

Answer:

The two regular cans of soup has a greater volume than the family size can of soup

Step-by-step explanation:

step 1

Find the volume of two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm

The volume is equal to

V=2[\pi r^{2} h]

we have

r=8/2=4\ cm ----> the radius is half the diameter

h=10\ cm

substitute

V=2[\pi (4)^{2} (10)]

V=320\pi\ cm^{3}

step 2

Find the volume of one family can of soup, with a diameter of 10 cm and a height of 12 cm

The volume is equal to

V=\pi r^{2} h

we have

r=10/2=5\ cm ----> the radius is half the diameter

h=12\ cm

substitute

V=\pi (5)^{2} (12)

V=300\pi\ cm^{3}

therefore

Compare the volumes

320\pi\ cm^{3} > 300\pi\ cm^{3}

The two regular cans of soup has a greater volume than the family size can of soup

What is the surface area of the triangular prism?
trasher [3.6K]

The surface area of the triangular prism is: B. 72 sq. ft

<h3>Surface Area of a Triangular Prism</h3>
  • The surface area of a triangular prism is given by the formula: SA = bh + (s1+s2+s3)H
  • Where, b is the base, h is the height, and s1+s2+s3 is the perimeter of the triangular base, H is the length of the prism.

Thus, given the triangular prism as shown in the diagram attached below, we have the following:

b = 4 ft

h = 3 ft

H = 5 ft

s1 + s2 + s3 = 3 + 4 + 5 = 12 ft

  • Plug in the values

Surface area = 4×3 + (12)5 = 12 + 60 = 72

Therefore, the surface area of the triangular prism is: B. 72 sq. ft
