Answer:

2.83 inches longer

Step-by-step explanation:

The SA of a cube is 6s^2.

Therefore the length of the side of the 1200 square inches cube is approximately 14.142 inches long.

The length of the side of the 768 square inches cube is approximately 11.314 inches long.

If you subtract those two numbers, you get the difference in the lengths which is approximately 2.83 inches.

Is the point 3/5 and 4/5 corresponds to an angle in the unit circle what is the csc
Mariulka [41]

<u>Answer:</u>

csc = 5/4

<u>Step-by-step explanation:</u>

Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0  with legs x and y and z as its hypotenuse.

Then using Pythagoras Theorem:

z^2=x^2+y^2

z^2=(\frac{3}{5} )^2+(\frac{4}{5} )^2

z^2 = \frac{9}{25} + \frac{16}{25}

z^2=\frac{25}{25}

z^2=1

Taking square root on both the sides:

z=1

Now, sin\alpha=\frac{4}{5}

and we know that csc = \frac{1}{sin\alpha }

Therefore, csc = 5/4.

Another math question :)
Travka [436]

Lets x = Mary's age

Emily is there years older than twice her sister Mary's age = 2x + 3

Sum of both is less than 30:

x + 2x + 3 < 30

Solve for x

3x + 3 < 30

3x < 27

x < 9

Mary's age = 9

Inequality represents Mary's possible age:

0 < x < 9

Answer is the second one

0 < x < 9
