4 The ratio of corresponding dimensions of two similar solids is 3/4. The surface

White raven [17]

4.

The ratio is 3/4 for corresponding dimensions, the ratio of their surface areas is equal to the square of this ratio:

$\sf (\dfrac{3}{4})^2=\dfrac{S}{96}$

Simplify the exponent:

$\sf \dfrac{9}{16}=\dfrac{96}{S}$

Cross multiply:

$\sf 9S=1536$

Divide 9 to both sides:

$\sf S\approx 170.7~m^2$

So the surface area of the second solid is 54 square meters.

The ratio is 3/4 for corresponding dimensions, the ratio of their volumes is equal to the cube of this ratio:

$\sf (\dfrac{3}{4})^3=\dfrac{720}{V}$

Simplify the exponent:

$\sf \dfrac{27}{64}=\dfrac{720}{V}$

Cross multiply:

$\sf 27V=46080$

Divide 64 to both sides:

$\sf V\approx 1706.7~m^3$

5.

A globe is a sphere, use the formula for the volume of a sphere:

$\sf V=\dfrac{4}{3}\pi r^3$

The radius is half of the diameter, so the radius here is 40/2 = 20. Plug it in the formula, use 3.14 to approximate for Pi:

$\sf V=\dfrac{4}{3}(3.14)(20)^3$

Simplify the exponent:

$\sf V=\dfrac{4}{3}(3.14)(8000)$

Multiply:

$\sf V\approx \boxed{\sf 33,493~in^3}$

Plz someone help me with this

Svetach [21]

Hey, There i hope you are haveing a great day :) So I look at the example so it should be the same I think like how you work out the mean by adding all the numbers and then diving them so, (8 + 4 + 8 + 8 + 10 + 2 + 4 + 4) = 48 and now you know you have got 8 numbers there a divide them so 48/8 = 6. and then I think you take away it so, 8 - 6 = 2 4 - 6 =-2 8 - 6 = 2 8 - 6 = 2 10 - 6 = 4 2 - 6 = -4 4 - 6 = -2 4 - 6 = -2 and then 2 + -2 + 2 + 2 + 4 + -4 + -2 + -2 divide 8 = 0 and you can't divide anything by 0 so that would be the answer.

Mention the difference between fossils fuel and alternative energy source with examples.

kvv77 [185]

Answer:

comparing fossils with other engerys:

Most alternatives energy sources doesn't have as much pollution produce like fossil fuel does,

Fossil comes from underground or persevered by nature, when others can be made by renewable resources, such as Wind(windmills) , sun (solar), and water (those rolly things)
