a rectangular prism is 18 inches long 6 1/2 inches wide and has a volume of 292 1/2 cubic inches. which equation can u use to fi
zhuklara [117]

The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches

<h3>Volume of a rectangular prism</h3>
  • v = lwh

where

l = length

w = width

h = height

Therefore,

l = 18 inches

w = 6 1 / 2  = 13 / 2 inches

h  =?

v = 292 1 / 2  = 585 / 2

Therefore,

h = v / lw

h = 585 / 2 × 1 / 18 × 2 / 13

h = 585 / 234

h = 2.5 inches

If 36 is 90% of a value, what is that value?
laila [671]
You know 36 is 90% of a value, so it will equal 90/100.
Multiply 90/100 types x (value). Easiest way is to simplify 90/100 = 9/10.
x = 36 / 9/10
x = 360 / 9
x = 40
Therefore, the value would be 40.

Answer:x=3

Step-by-step explanation:

the 3 angles of a triangle equal 180

you add 105 and 46, which equals 151

you subtract 151 from 180 to see what the missing angle is (29)

you would make 6x+11 equal to 29

-subtract 11 from 29= 18

6x/6, 18/6

the answer is 3
