First off.. we need to get the units the same. All in hours,
or all in minutes. 36 minutes = 36/60 hours = 3/5 hours = 0.6 hours.
12 minutes = 12/60 hours = 1/5 hours = 0.2 hours
Set up a proportion:
0.2 is to 0.6 as x is to 22.5
x/22.5 = 0.2/0.6
x = 0.2(22.5)/0.6
x = 7.5 hours
thanx
heyaaaaa
Answer:
The answer to your question is 64 mm³
Step-by-step explanation:
To calculate the volume of a cube just multiply the length of a side three times.
Data
cube-shaped crystal
length = 4 mm
Formula
Volume = length³
Substitution
Volume = (4 mm)( 4 mm)(4 mm)
Simplification and result
Volume = 64 mm³
Answer:
h = 3r - 5
Step-by-step explanation:
We know the height (h) of the cylinder is roughly three (3) times it's radius (r), but not exactly... it's 5 units less.
So, we start by stating that the height is 3 times its radius:
h = 3r
Then we apply the correction mentioned in the question:
h = 3r - 5
It's not important for us to know what the units are... they could be cm, inches, meters or miles. We don't care.
A restricted value is a value that will make the fraction undefined, and thus will make it impossible to exist.
Restricted values can exist in two forms: asymptotes and holes.
By simplifying all sides of this expression, we can find the restricted values.
After finding factors, and then cancelling like factors, keeping in mind the original factors in the denominator, we can find three restrictions:
1, 2, and -2.
