ozzi

Answer:

$24.375

Step-by-step explanation:

Regular price of sandals = $32.50

Store sells sandals for 25% of the regular price.

Hence selling price =(100-25)% of the regular price.

In other words, selling price = 75% of regular price

= 75% of $32.50

= \[\frac{75}{100}*32.50\]

= \[24.375\]

Hence the sale price of the sandals is $24.375

This is $8.125 less than the regular price of the sandal.

A triangular prism has a height of 12 cm. The triangular base is a right triangle whose side lengths are 3 cm, 4 cm, and 5 cm. W
Montano1993 [528]

Answer:

The volume of the prism is 72 cubic cm.

Step-by-step explanation:

This we know because a triangle with sides of 3 units, 4 units, and 5 units must be a 3–4–5 right triangle, the catheti (“legs”) of which are 3 and 4 units. So the area of the base is

3 cm. * 4 cm. / 2 = 6 square cm.

Lastly, the volume of the prism is the base area multiplied by the height:

6 square cm. * 12 cm. = 72 cubic cm.
