What is 575% written as a mixed number?

pav-90 [236]

Answer:

575% as a mixed number is $5\frac{3}{4}$

Explanation:

575% is equivalent to $\frac{575}{100}$ which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as $\frac{75}{100}$ . This value can be simplified by dividing both the numerator and the denominator by 25. This would give us $\frac{3}{4}$

Back to our number:

$5.75 = 5 + 0.75 = 5 + \frac{75}{100} = 5 + \frac{3}{4} = 5\frac{3}{4}$

Hope this helps :)

Prism M and pyramid N have the same base area and the same height. Cylinder P and prism Q have the same height and the same base

m_a_m_a [10]

Answer:

Answer Cone Z and Cylinder Y.

Step-by-step explanation:

The relationship between the volume of the cone and the volume of the cylinder with the same height and same base is the volume of the cone is 1/3 of the volume of the cylinder.

The formula for the volume of the cone is :

V = 1/3π $r^{2}$ h

The formula for the volume of the cylinder is :

V = π $r^{2}$ h

Let be the height of the cylinder Y. Therefore the height of the cone Z is 3h, when we put it into the formula we get :

V = 1/3π $r^{2}$ (3h) = π $r^{2}$ h

Therefore Cone Z and Cylinder Y have same volume.
