A railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters, and a height of 4 meters.

larisa86 [58]

The volume of railway car is 216 cubic meters

Solution:

Given that, Railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters and a height of 4 meters

To find: volume of railway car

The volume of rectangular prism is given as:

$v = l \times w \times h$

Where,

"l" is the length and "w" is the width and "h" is the height of prism

From given question,

length = 18 meters

width = 3 meters

height = 4 meters

Substituting the values, we get

$v = 18 \times 3 \times 4 = 216$

Thus volume of railway car is 216 cubic meters

Find an equation of the line that goes through the points (10,34) and (-1,10)

kotykmax [81]

Answer:

Given points are ( 10 ,34 ) and ( -1 , 10)

Step-by-step explanation:

The equation of line is given by 

first we can find slope (m) 

= (y2 - y1) / ( x2 - x1)

= 34-10/10+1

 =24/11

Now the equation is

y - y1 = m ( x - x1) 

y - 10 = 24/11 ( x +11)

11 ( y - 10 ) = 24 (x + 11)

11y - 110 = 24x + 264

24x + 264 +110-11y =0

24x - 11y + 374 = 0

which is the required equation
