Use the surface area formula for a cylinder! 2πrh+2πr2
Plug in what you know! (If the diameter is 8, then that means the radius is 4.)
r = 4
h = 12
2π(4)(12) + 2π(4)(12) = 402.12
I hope this helps! :)
First, you would turn 2 1/9 into an improper fraction. 2 1/9 is now turned into 19/9. Now, you need to find a common denominator between 19/9 and 5/6. The least common denominator, which is the smallest number that both denominators can multiply to, is 18. 19/9 is turned into 38/18 (which is still 19/9 when simplified). 5/6 is turned into 15/18. Now, since both 38/18 and 15/18 have a common denominator, we can write the fraction like (38-15)/18. 38-15 is 23, so your answer is 23/18. When simplified, 23/18 becomes 1 5/18.
Answer:
Step-by-step explanation:
grouping like terms
2a-3a+10b+5b-c+c
-a+15b
It’s a 30-60-90 triangle
the side opposite of 60 would be the side that is root 3
the answer would be 5 times root 3
Answer:
The given function is not a proportional relationship
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
In this problem we have
This is the equation of the line in slope intercept form
where
e ---> represents her daily earnings
h ---> represents the number of hours she works
we have
The slope is equal to
The y-intercept is
Remember that
In a proportional relationship the y-intercept is equal to zero, because the line passes through the origin
In this problem, the y-intercept is not equal to zero, so this line don't pass through the origin
therefore
The given function is not a proportional relationship
