a rectangular prism has a volume of 1374.28 cubic inches.The prism is 9.4 inches wide and 17.2 inches long.What is the height of

NISA [10]

The volume V of a prism can be found by:
The volume of a rectangular prism can be found through:
$V=lwh$
Where l is the length, w is the width, and h is the height.

The height can be found by rearranging the equation to:
$h= \frac{V}{wl}$

Take the volume (1374.28) and divide it by the length times the width (9.4*17.2=161.68).
1374.28/161.68= 8.5 inches is the height of the prism.

A typical running track is an oval with 74-m-diameter half circles at each end. a runner going once around the track covers a di

denpristay [2]

Answer:

Her centripetal acceleration during the turn at each end of the track is $0.432\, \frac{m}{s^{2}}$

Step-by-step explanation:

Total distance covered in one round , D= 400 m

Time taken to cover one round , T = 1 min 40 s = 100 sec

Speed of runner , $V=\frac{D}{T}=\frac{400}{100}\, \frac{m}{s}= 4.0\, \frac{m}{s}$

Now centripetal acceleration is given by

$a_c=\frac{V^{2}}{R}$

where $V= 4.0\frac{m}{s}$

$Radius, R= \frac{Diameter}{2}=\frac{74}{2}m=37\, m$

$\therefore a_c=\frac{4^{2}}{37}\, \frac{m}{s^{2}}=0.432\, \frac{m}{s^{2}}$

Thus her centripetal acceleration during the turn at each end of the track is $0.432\, \frac{m}{s^{2}}$

What is the length of pr ? PLEASE HELP

Karolina [17]

The angles in the triangles are the same, so you know the triangles are similar. Sides PQ and AB correspond as do sides PR and AC. Because the triangles are similar, you know that
PR/AC = PQ/AB
PR/24 = 5/20
Multiplying this equation by 24 gives
PR = 24*(5/20) = 6

The appropriate choice is ...

Identify the domain and range of the relation:<br> (-5,-3), (-2,1), (1,4), (2,5)

jonny [76]

Domain is the x-coordinate and range is the y - coordinate

$\therefore \: domain = \{ - 5, \: - 2, \: 1, \: 2 \} \\ \\ \&\: range = \{ - 3, \: 1, \: 4, \: 5\}$
