ABCD is a square with an area of 49 cm2, and BE = 4.95 cm. Point E is the midpoint of 2 diagonal lines crossed inside the square
dezoksy [38]

Answer:

I suppose we want to find the side length of the square.

We know that:

The area of the square is 49cm^2

The distance between one of the vertices of the square and the middle of the square is:

BE = 4.95cm

Now let's remember some things.

For a square of side length L, the area is:

A = L^2

and the diagonal length is:

D = √(2)*L

In this case, we know that half of the diagonal is equal to:

BE = 4.95 cm

Then the diagonal is:

D = 2*BE = 2*4.95cm = 9.9cm

And for the diagonal formula, we have:

D =  9.9cm = √(2)*L

Then the side length is:

L = 9.9cm/√(2) = 7cm

And if we check the area of this square, is:

A = L^2 = (7cm)^2 = 49cm^2

So it checks.

Then we can conclude that the sidelength of the square is 7cm, which means that:

AB = 7cm

BC = 7cm

CD = 7cm

DA = 7cm

The mass of Mars is 6.42x10-23 kilograms. The mass of mercury is 3.3x10-23 kilograms. What is the combined mass in scientific no
Paraphin [41]

  • <em>combined mass in scientific notation can be written as</em> 97.2×10^{-24}  kg

  • Scientific notation can be regarded as a way of writing very large as well as  very small numbers.

Mars of mass= (6.42x10^{-23} kg )

Mercury= (3.3x10^{-23} kilograms)

Then we add together

(6.42x10^{-23} )+ (3.3x10^{-23}) kilograms.

= 9.45 × 10^{-24} kilograms

Therefore, combined mass in scientific notation can be written as 97.2× 10^{-24} kg

On your lab bench, you have 2 mystery metal cubes. each cube has a mass of 10.0 grams. cube a has a density of 10 g/cm3. cube b
lianna [129]
To compare both, we find the volume of both cubes as follows:

V of cube A = 10 g / 10 g/cm^3 = 1 cm^3

V of cube B = 10 g / 0.37 g/cm^3 = 27 cm^3

I think the correct answer from the choices listed above is option D. Each edge of cube b is three times larger than cube. Hope this helps. Have a nice day.
