Answer:

x ≈ 17.1 m

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² = 9² + 14.5² = 81 + 210.25 = 291.25 ( take the square root of both sides )

x = \sqrt{291.25} ≈ 17.1 m ( to 1 dec. place )

Gnesinka [82]

s - the number of the t-shirts;

h - the number of hats:

The system of equations:

s + h = 23

10 s + 12 h = 246

--------------------------

s = 23 - h

10 * ( 23 - h ) + 12 h = 246

230 - 10 h + 12 h = 246

2 h = 246 - 230

2 h = 16

h = 16 : 2

h= 8

s = 23 - 8

s = 15

Answer: The basketball team sold 15 t-shirts and 8 hats.

Find the volume of the rectangular prism.<br> 9 cm<br> 9 cm<br> 9 cm
cricket20 [7]

Answer:

3672 cm^3

Step-by-step explanation:

There is a typo in the question, the lengths of the sides of the prism are:

24 cm

9 cm

17 cm​

(otherwise, if all sides were 9 cm, it would be a cube, not a prism)

The volume of a rectangular prism is given by:

V=l\cdot w\cdot h

where:

l is the length of the prism

w is the width of the prism

h is the height prism

In this problem,

l=24 cm (length)

w=9 cm (width)

h = 17 cm (height)

Therefore, the volume of the prism is:

V=24\cdot 9 \cdot 17 = 3672 cm^3
